P: Glossary Terms

P

preferred stock(preferred shares) Stocks

An equity or hybrid security that generally has priority over common stock for dividends and liquidation proceeds, often with limited voting rights.

public companyStocks

A company whose shares are registered with a securities regulator and trade on an exchange or an over-the-counter venue, so any investor can buy them. In the United States it files periodic disclosures with the SEC, including annual and quarterly reports and material-event notices, and answers to outside shareholders who elect its board and vote on major corporate matters.

private companyStocks

A business whose ownership sits with founders, employees, family or private investors rather than with shareholders trading on an exchange. It is not required to publish audited quarterly financials, so outsiders see little data on it. Holders usually realize value only through a sale of the business, a company buyback, a negotiated secondary transaction or an eventual public listing.

penny stockStocks

Under SEC Rule 3a51-1, a low-priced equity that fails the rule's exclusions for exchange listing, minimum price and minimum net tangible assets. The classification triggers extra broker-dealer disclosure, suitability and risk-warning obligations before a customer can buy. Securities in this category typically have thin volume, wide spreads and limited public financial reporting.

public floatStocks

Shares considered available for public trading after excluding certain insider, affiliate, or restricted holdings; definitions vary by context and rule. Full guide →

price improvementStocksCrypto

Execution at a price better than the relevant quoted or order price benchmark, such as a retail buy filled below the best displayed ask.

price impactStocksCrypto

The price change caused by the user's own order consuming available liquidity, distinct from unrelated market movement during execution.

payment for order flowStocks

Compensation a broker receives from a wholesale market maker for routing customer orders to it. The market maker earns the spread on those orders and may offer price improvement against the public quote. United States brokers must disclose these arrangements and their routing practices, and the arrangement creates a documented conflict between routing revenue and the duty of best execution. Full guide →

pre-market tradingStocks

Trading that takes place before a stock exchange's regular session opens, typically with lower volume and wider spreads than the regular session.

prime brokerStocks

A bank or broker-dealer providing a hedge fund or other professional client with a bundled service: custody, consolidated financing and margin, securities lending to support short positions, settlement of trades done away with other executing brokers, and reporting. Terms are negotiated privately, and the provider can raise margin requirements or recall borrowed stock, making it a source of funding risk.

pattern day traderStocks

A FINRA designation applied to a margin-account holder who executes a defined number of same-day round trips within a rolling five-business-day window where those trades are a significant share of total activity. The designation carries a minimum account equity requirement set by FINRA rule, and the account is restricted from further day trading until that equity is maintained. Full guide →

pretax income(income before taxes, EBT) Stocks

Income before the recognition of income-tax expense or benefit. Full guide →

property plant and equipmentStocks

The long-lived physical assets a business uses to operate: land, buildings, machinery, vehicles, fixtures and construction in progress. The balance is carried at historical cost less accumulated depreciation, so the recorded figure often differs sharply from replacement or market value. Growth in the gross balance shows where a capital-intensive company is actually investing.

payout ratioStocks

The share of profit distributed to holders, computed as dividends per share divided by earnings per share, or total distributions divided by net income. A cash-based variant uses free cash flow instead, which is more informative because distributions are paid in cash. A reading above one means the distribution exceeds current profit and is being funded from elsewhere.

P/E ratioStocks

A stock's price divided by its earnings per share, used to gauge how much investors are paying for each dollar of a company's earnings.

PEG ratioStocks

The P/E ratio divided by a company's expected earnings growth rate, intended to adjust valuation for how fast a company is growing. Full guide →

price-to-salesStocks

A valuation ratio dividing market capitalization by trailing or forward revenue, or share price by revenue per share. Because it uses the top line it stays meaningful for a company with no profit, but it ignores margins and capital structure entirely, so a low reading on a thin-margin, heavily indebted business is not comparable to the same reading elsewhere. Full guide →

price-to-bookStocks

A valuation ratio dividing share price by book value per share, where book value is shareholders equity. It compares the market's assessment against accounting net worth. The measure works best for banks and insurers whose assets are carried near fair value, and poorly for firms whose value sits in brands, software or research that accounting does not capitalize. Full guide →

price-to-free-cash-flowStocks

A valuation ratio dividing market capitalization by free cash flow, meaning operating cash flow less capital expenditures. It is harder to manipulate than a profit-based multiple because it uses cash actually generated after maintaining the asset base, but it is distorted in years with unusual capital spending, large working capital swings or heavy acquisition activity.

precedent transactionsStocks

A relative valuation method that prices a business from the multiples paid in completed acquisitions of comparable companies. Because those prices include a control premium and deal-specific synergies, the multiples usually sit above trading comparables. Results depend on the market conditions prevailing when each deal closed, so stale comparisons can mislead badly.

profit warningStocks

A company announcement, issued ahead of a scheduled report, that results will fall short of prior guidance or market expectations. It is made to avoid a selective or delayed disclosure of material information. Because the news arrives outside the normal reporting calendar and is unambiguous in direction, the price reaction is often larger than at a regular release.

post-earnings announcement driftStocks

The documented tendency for a stock to keep moving in the direction of a results surprise for weeks afterward, rather than fully adjusting at the moment of release. It is one of the longest-standing anomalies in academic finance, usually attributed to slow processing of new information. Its measured magnitude has varied over time and is reduced by trading costs.

payable dateStocks

The day a declared distribution is actually paid to holders of record. It follows the declaration date, the ex-dividend date and the record date in the corporate action sequence, usually by a few weeks. Cash appears in a holder's account on or shortly after that day, depending on how the custodian processes the payment.

poison pillStocks

A shareholder rights plan a board adopts to deter a hostile takeover, triggering when an acquirer crosses a stated ownership threshold. Once triggered, every other holder can buy newly issued shares cheaply, diluting the acquirer's stake and making further accumulation prohibitively expensive. The effect is to force a bidder to negotiate with the board rather than buy control in the market.

proxy fightStocks

A campaign by a dissident holder to win votes from other shareholders in order to replace directors or pass a resolution against the board's recommendation. Both sides file solicitation materials with the SEC and approach holders directly. Universal proxy rules in the United States let shareholders combine nominees from both slates on a single card.

price actionStocksCrypto

Analysis focused primarily on price movement, highs, lows, closes, ranges, and market structure rather than relying exclusively on derived indicators. Full guide →

point and figureStocksCrypto

A charting method plotting columns of X marks for rising prices and O marks for falling ones, advancing a column only when price moves by a defined box size and switching columns only on a reversal of a set number of boxes. Time is not an axis, so quiet stretches add nothing and only meaningful moves appear on the chart.

previous day high(PDH) StocksCrypto

The prior regular session's highest traded price, often used as a reference for breakouts, liquidity, and intraday structure.

previous day low(PDL) StocksCrypto

The prior regular session's lowest traded price, often used as a reference for breakdowns, liquidity, and intraday structure.

percentage price oscillatorStocksCrypto

A momentum indicator equal to the difference between two exponentially smoothed price lines expressed as a percentage of the longer one, rather than in raw price units. Stating the result in percentage terms is what distinguishes it from MACD and makes readings comparable across instruments trading at different price levels or across a long history.

Parabolic SAR(PSAR) StocksCrypto

A trend-following indicator plotting a trailing stop-and-reversal level that accelerates toward price as a trend persists. Full guide →

point of controlStocksCrypto

The price level with the greatest traded volume over a chosen period in a volume profile, marking where the most business was transacted and, by inference, where the largest number of positions were established. Traders watch it as a magnet for price and as a reference for whether the market accepts or rejects that level on a retest.

put-call ratio(PCR) StocksCryptoOptions

A ratio comparing put activity with call activity using volume or open interest; interpretation depends on which data and market are measured. Full guide →

piercing patternStocksCrypto

A two-candle bullish reversal in which a down period is followed by an up period that opens beneath the prior low and closes back above the midpoint of the previous body without fully covering it. The deeper the close pushes into the previous body, the stronger the signal is considered, and confirmation is usually sought from the next period. Full guide →

pin barStocksCrypto

A candle with a small body at one end and a long shadow at the other, typically two-thirds or more of the total range, showing that price moved decisively in one direction during the period and was rejected before the close. It is read at a support or resistance level, where the tail marks the failed excursion beyond it.

position tradingStocksCrypto

A longer-horizon strategy that holds positions for weeks to months, or longer, to capture a sustained trend, tolerating short-term volatility along the way.

pullback tradingStocksCrypto

Entering in the direction of an established trend after price retraces part of the prior move, rather than chasing the initial thrust. Common reference points for the retracement include a moving average, a prior breakout level, or a Fibonacci retracement zone. The intended benefit is a tighter stop and a better entry price. The tradeoff is that a strong trend may never offer the retracement.

pairs tradingStocksCrypto

A relative-value strategy that trades two linked securities based on a defined spread or residual relationship. A pairs strategy must specify the hedge ratio, stability tests, execution on both legs, borrow assumptions, and invalidation conditions. Full guide →

parameter optimizationStocksCrypto

Searching candidate strategy or model settings to improve a chosen objective, which can easily overfit without proper validation.

profit factorStocksCrypto

Gross profits divided by gross losses across a set of trades; values above one indicate total winning dollars exceeded total losing dollars before other considerations.

position sizingStocksCrypto

Determining how large a trade should be, typically based on account size, the distance to a stop-loss, and the percentage of capital the trader is willing to risk on that trade. Full guide →

profit targetStocksCrypto

The price level at which a trader plans to exit a position in gain, chosen from a measured chart objective, a volatility multiple, a support or resistance zone, or a fixed multiple of the amount risked. It is the numerator in the reward-to-risk calculation used to judge whether a setup is worth taking. Unlike a resting order, it can exist only as a written plan.

portfolio marginStocksCrypto

A risk-based brokerage margin methodology that considers modeled portfolio losses across scenarios rather than applying only position-by-position fixed percentages.

put optionStocksOptions

A contract giving the holder the right, but not the obligation, to sell an underlying asset at a set price before expiration, often used as a bearish or hedging alternative to shorting.

payoff diagramStocksOptions

A chart plotting a position's profit or loss on the vertical axis against the price of the underlying on the horizontal axis, usually drawn as of expiration. Kinks appear at each strike, and the points where the line crosses zero mark breakeven prices. It makes the maximum gain, maximum loss, and breakeven levels of a multi-leg structure visible at a glance.

protective putStocksOptions

A strategy combining long underlying exposure with a long put to establish a downside floor for a premium cost.

pin riskStocksOptions

The risk around expiration that the underlying finishes near a strike, creating uncertainty about exercise, assignment, and resulting stock exposure.

price discoveryStocks

The process by which a market arrives at a price reflecting the information and preferences of its participants, through the interaction of bids and offers over time. It works fastest where liquidity is concentrated and quoting is continuous. Auctions at the open and close, and reopenings after a halt, are formal mechanisms designed to gather interest so a single clearing level can be established.

passive orderStocks

An order that waits to be traded against rather than crossing the spread, typically a resting limit priced at or behind the best quote. It aims to earn the spread or a liquidity rebate and avoids the immediate cost of aggression. The risks are non-execution and adverse selection, where the fill arrives precisely because price is about to move against the holder.

PCE price indexStocksCrypto

A measure of consumer inflation built from the personal consumption expenditures component of the national accounts, published monthly by the Bureau of Economic Analysis. Its basket updates continuously to reflect substitution between goods as relative prices change, and it covers spending made on households' behalf such as employer-paid health care. The Federal Reserve states its inflation target in terms of this index.

producer price indexStocksCrypto

A measure of the average change in selling prices received by domestic producers for their output, published monthly in the United States by the Bureau of Labor Statistics. It covers goods, services, and construction at various stages of processing. Because it captures costs earlier in the supply chain, it is watched as a possible leading signal for consumer prices and as an input to margin analysis.

purchasing managers indexStocksCrypto

A diffusion index built from surveys of purchasing executives about new orders, output, employment, supplier deliveries, and inventories. Respondents report whether conditions improved, stayed the same, or worsened, and the result is scaled so readings above 50 indicate expansion and below 50 contraction. Because it is survey based it publishes ahead of hard data, which makes it a widely watched early signal.

proof of workCrypto

A consensus mechanism in which participants (miners) compete using computational power to add new blocks, making it economically expensive to rewrite transaction history. Full guide →

proof of stakeCrypto

A consensus mechanism in which validators lock up (stake) network assets and are rewarded or penalized based on their participation, replacing computational mining with capital at risk.

peer-to-peer network(P2P) Crypto

A network architecture in which nodes communicate directly with one another rather than relying on a single central server.

public keyCrypto

Cryptographic information derived from a private key and used to verify digital signatures; blockchain addresses are often derived from public keys.

private keyCrypto

Secret cryptographic information used to produce the digital signatures required to authorize transactions from a blockchain address; anyone who obtains it can typically move the associated funds. Full guide →

priority fee(tip) Crypto

An optional Ethereum transaction fee paid to encourage faster inclusion by a validator, commonly called a tip.

proposer-builder separation(PBS) Crypto

An architecture that separates block construction from the consensus participant proposing the block to reduce centralization and improve MEV markets.

perpetual futures(perpetual swap, perp) Crypto

A derivative contract with no fixed expiration that tracks an underlying cryptoasset using funding, margin, and liquidation mechanisms. Full guide →

perpetual swapCrypto

A derivative contract tracking an underlying asset's price with no expiration date, so a position can be held indefinitely. A periodic funding payment between longs and shorts pulls the contract toward the spot index: when it trades above the index, longs pay shorts, and the reverse when it trades below. Positions are margined and can be liquidated if collateral falls below maintenance requirements.

payment tokenCrypto

A token whose intended purpose is transferring value between parties rather than granting access to a service or a claim on a protocol's revenue. Bitcoin and stablecoins used for settlement are the common examples. Regulators in several jurisdictions treat this category separately from security and utility tokens, with rules focused on money transmission, reserve backing, and anti-money-laundering obligations.

protocol revenueCrypto

Value retained by a crypto protocol or its stakeholders after specified payments to users, liquidity providers, validators, or other participants, depending on the accounting methodology.

protocol feesCrypto

Gross fees paid by users or generated by protocol activity before deciding how those fees are distributed.

pre-mineCrypto

Tokens or coins created and allocated before broad public mining, validation, or market participation begins.

protocol-owned liquidity(POL) Crypto

Liquidity positions owned by a protocol or DAO treasury rather than temporarily rented through external token incentives.

price oracleCrypto

A service that delivers external market data to smart contracts, which cannot read information outside their own blockchain. Designs range from a single reporting party to decentralized networks that aggregate many independent sources and publish a signed median on-chain. Because liquidations and derivative settlements depend on the reported figure, manipulating a thin source is a recurring attack against protocols relying on one feed.

protocol riskCrypto

The chance of loss arising from how a decentralized system is built and governed, separate from market price moves. It covers contract bugs, upgradeable proxies and admin keys that can change the rules, oracle dependencies, economic designs that fail under stress, and governance capture. Audits reduce it but do not remove it, since audited code has been exploited through logic errors and dependency flaws.

peg stability moduleCrypto

A contract that lets users swap a stablecoin for a designated reserve asset at or near a fixed rate, usually for a small fee, giving arbitrageurs a direct route to correct deviations from the target price. It anchors the peg more tightly than open-market arbitrage alone. The cost is that backing shifts toward whatever reserve asset the module accumulates, inheriting that asset's own risks.

Puell MultipleCrypto

Daily Bitcoin miner issuance value divided by a historical moving average of issuance value, used to contextualize miner revenue cycles. Full guide →

proof of reserves(PoR) Crypto

A method for demonstrating control of specified assets held by a custodian, often using cryptographic proofs and attestations; it does not by itself prove liabilities or solvency. Full guide →

proof of liabilitiesCrypto

A method for demonstrating customer obligations or liabilities so asset proofs can be evaluated against what the custodian owes users.

paper walletCrypto

Private key material printed or handwritten and stored offline, an early approach to cold storage that keeps keys away from any connected device. Its weaknesses are practical: the key is exposed when generated and again when spent, paper degrades and burns, and partial spends through an unfamiliar interface have sent change to addresses the owner did not control. Hardware wallets have largely replaced the format.

pump and dumpCrypto

A scheme in which promoters hype an asset to drive its price up, then sell their own holdings into the buying they created, leaving later buyers holding the loss.

pig butcheringCrypto

Long-running investment fraud in which the operator builds a personal or romantic relationship over weeks or months before introducing a trading platform they control. Small withdrawals are honored early to establish credibility, account screens display fabricated gains, and pressure to deposit escalates as the balance grows. Withdrawal is eventually blocked behind invented taxes or fees. The name comes from the fattening metaphor used by the criminal networks that run these operations at industrial scale.

Ponzi scheme(Ponzi schemes) CryptoStocks

Frauds that pay returns to existing investors out of money contributed by new investors rather than from any economic activity. Reported returns look steady and unusually consistent because they are written rather than earned, and the scheme survives only while inflows exceed redemptions. Recurring markers include an unexplained strategy, growing difficulty withdrawing, statements produced by the operator alone, and no independent custodian holding the assets.

pyramid schemeCrypto

Structure that pays existing participants from the entry fees of new recruits rather than from any product sold or return generated. Each layer requires a larger layer beneath it, so the arithmetic of recruitment forces collapse once new entry slows, leaving the most recent joiners with losses. It differs from a Ponzi scheme in that participants are told to recruit directly, while a Ponzi is presented as a passive investment managed by a central operator.

pre-trade checklistStocksCrypto

Short, fixed list of conditions verified immediately before an order is sent, so routine errors are caught while the trade can still be abandoned. Typical items include whether the setup matches the plan, the position size implied by the stop distance and the account risk limit, upcoming scheduled events, the instrument's liquidity and spread, and correlation with positions already open. Its value comes from being identical every time rather than from being long.

post-trade reviewStocksCrypto

Structured examination of completed trades against the plan that produced them, separating the quality of the decision from the quality of the outcome. A typical review records the setup, the entry and exit rationale, the size chosen, whether the rules were followed, and what was knowable at the time. Because a single result carries little information in a high-variance process, reviews are aggregated across many trades to surface recurring errors rather than to judge any one result.

probability weightingStocksCrypto

Feature of prospect theory in which people act on transformed probabilities rather than stated ones, overweighting small probabilities and underweighting moderate to high ones. This explains why the same person buys lottery-like payoffs and also insures against rare losses, and why deep out-of-the-money options can trade above a risk-neutral estimate. The weighting function is nonlinear and inverse-S shaped, and it describes observed psychology rather than a pricing rule.

prospect theoryStocksCrypto

Model of choice under risk developed by Kahneman and Tversky in which outcomes are evaluated as gains and losses relative to a reference point rather than as final wealth levels. Its value function is concave for gains, convex for losses, and steeper for losses than for gains, which produces loss aversion. Combined with probability weighting it reproduces behavior that expected utility theory misses, including risk-seeking to avoid realizing a loss and risk aversion after a gain.

PDTStocks

Pattern day trader, a FINRA classification applied to a margin account that executes day trades above a defined frequency within a rolling five business day window, where those day trades also make up more than a set share of total trading in the account. A flagged account must keep minimum equity above a level fixed by FINRA rule before it may day trade, and falling below that level triggers a restriction until equity is restored. Cash accounts are outside the rule but face settlement constraints instead.

premiumStocksOptions

Price paid by the buyer of an option to the seller in exchange for the rights the contract conveys, quoted per share and multiplied by the contract size to give the cash amount. It splits into intrinsic value, the amount by which the option is in the money, and extrinsic value, which reflects time remaining, implied volatility, rates, and expected dividends. The buyer's maximum loss is this amount; the seller receives it and takes on the contract's obligation. Distinct from the premium in physical metal and coin markets, which is the amount charged above the melt value of the metal an item contains.

prospectusStocks

A formal disclosure document filed with the SEC that describes a securities offering, including the issuer's business, financials, and risk factors.

pivotStocks

Point at which price reverses direction, and separately a calculated reference level. As a structure, a pivot high is a bar whose high exceeds a defined number of bars on each side, and a pivot low is the mirror; these define the swing points used for trendlines and stop placement. As a calculation, the classic pivot point is the average of the prior period's high, low, and close, from which support and resistance levels are derived by fixed formulas.

pullbackStocksCrypto

A temporary move against the prevailing trend that does not necessarily invalidate the larger directional structure.

PPOStocksCrypto

Percentage price oscillator, the difference between a fast and a slow exponential moving average expressed as a percentage of the slow average, multiplied by one hundred. It carries the same information as the moving average convergence divergence indicator but in relative terms, so readings are comparable across assets trading at different price levels and across time for one asset whose price has changed a great deal. A signal line, itself an average of the oscillator, is normally plotted with it.

POCStocks

Point of control, the price level at which the most volume traded over a chosen period, taken from a volume profile that distributes traded volume across price rather than across time. It marks where the market spent the most activity and therefore where the largest number of positions were established, so it is watched as a reference price often returns to. It shifts as new volume accumulates, and each session, week, or range has its own.

portfolioStocksCrypto

The complete set of assets held by an investor or managed as a single unit and evaluated as a whole rather than position by position. Its return is the weighted average of its components' returns, but its volatility is not, because that depends on how the components move together: adding an asset less than perfectly correlated with the rest can lower total volatility even when that asset is volatile on its own. Construction therefore focuses on weights and correlations. Full guide →

putStocksOptions

Option contract giving the holder the right to sell the underlying at the strike price until expiration. Its value rises as the underlying moves below the strike, and the buyer's loss is limited to the premium paid. The seller receives the premium and must buy the underlying at the strike if assigned, so exposure extends to the strike price less the premium if the underlying falls toward zero. Puts are used both to express a view on declines and to hedge a long holding.

PCEStocksCrypto

Personal consumption expenditures price index, a United States inflation measure published monthly by the Bureau of Economic Analysis covering prices of goods and services bought by or on behalf of households. Its weights update each period and reflect actual spending patterns including substitution between goods, and its scope includes items paid for by third parties such as employer-funded health care. The Federal Reserve states its inflation target in terms of this index rather than the consumer price index.

PPIStocksCrypto

Producer price index, a United States measure of the average change in selling prices received by domestic producers, published monthly by the Bureau of Labor Statistics. It is organized by industry, by commodity, and by stage of demand, and unlike consumer price measures it excludes imports and sales taxes. Because it captures prices earlier in the production chain, it is watched for cost pressure that may or may not pass through to consumer prices later.

PMIStocksCrypto

Purchasing managers' index, a diffusion index built from surveys of purchasing executives about whether activity such as new orders, output, employment, supplier deliveries, and inventories rose, fell, or was unchanged. Responses are converted into an index where fifty separates expansion from contraction, so the level indicates direction and breadth rather than a growth rate. Because these surveys close and publish quickly, they are followed as early readings on activity ahead of official statistics.

PoWCrypto

Proof of work, a consensus mechanism in which participants compete to find a hash below a target, which requires many attempts and therefore real computation and energy. The winner proposes the next block and receives the reward. Because the work is expensive to perform and trivial to verify, rewriting history requires redoing all the accumulated work faster than the honest network extends it, which is what makes settled blocks costly to reverse.

PoSCrypto

Proof of stake, a consensus mechanism in which the right to propose and attest to blocks is assigned according to how much of the network's asset a validator has locked as stake, rather than by computation. Misbehavior such as signing conflicting blocks is punished by slashing part of that stake, so the security assumption shifts from energy expenditure to capital at risk. Selection is randomized and weighted by stake, and rewards come from issuance and transaction fees.

permissionlessCrypto

Describing a network anyone can join and use without approval, so running a node, submitting transactions, deploying contracts, and participating in consensus require only meeting the protocol's technical and economic conditions. Identity is not checked at the protocol layer, and access cannot be revoked by an administrator. Rules are enforced by the software each participant chooses to run, which means changing them requires broad adoption rather than a central decision.

permissionedCrypto

Describing a network in which participation is restricted to identified and approved parties, so an operator or a consortium controls who may run nodes, submit transactions, or validate. This supports known-counterparty settlement, confidentiality between participants, and formal governance, at the cost of depending on that authority. Such networks commonly use classical Byzantine fault tolerant consensus rather than open mining or staking, because the validator set is fixed and known in advance.

proposerCrypto

The consensus participant selected to propose a block for a particular slot, round, or height.

perpCryptoFuturesStocks

Perpetual futures contract, a derivative that tracks an underlying asset's price with no expiration date, so a position can be held indefinitely. Convergence toward spot is maintained by a funding rate exchanged periodically between the two sides: when the contract trades above the index, longs pay shorts, and when it trades below, shorts pay longs. Positions are margined and can be liquidated when maintenance margin is breached, and leverage limits are set by the venue.

proxyStocks

A contract that holds an application's storage and address while forwarding every call to a separate implementation contract holding the logic. Because the implementation address can be replaced, the application can be upgraded without users migrating. Whoever controls that upgrade authority can change the rules the contract enforces, which is why proxy detection and the identity of the upgrade admin are standard checks. In equity markets the same word means a shareholder vote cast by an authorized representative.

phishingCrypto

A fraud that impersonates a trusted party to make the target hand over credentials, a seed phrase, or a transaction signature. Delivery is typically a spoofed email, message, advertisement, or lookalike domain leading to a cloned interface. In crypto the payload is often not a password prompt but a signature request granting token spending approval, so the loss happens through a transaction the victim genuinely authorized rather than through a stolen key. Full guide →

panicStocksCrypto

A rapid, emotion-driven exit in which holders sell to end the discomfort of a falling price rather than in response to changed information. It clusters, because falling prices trigger stop orders and margin calls that force further selling, producing accelerating declines on rising volume. Panic phases end when forced sellers are exhausted rather than when the news improves, which is why price often turns before sentiment does.

patienceStocksCrypto

In trading, the discipline of waiting for a setup that meets predefined conditions instead of taking a position because time has passed without one. It is what turns a written strategy into an actual filter. A system with an edge only realizes that edge across the specific situations it was tested on, so entries taken outside those conditions are untested trades no matter how any individual one turns out.

Pattern Day Trader (PDT) RuleStocks

A FINRA rule requiring a margin account that executes four or more day trades within five business days (where those trades exceed 6% of account activity) to maintain a minimum equity balance. FINRA amended the rule effective June 4, 2026, reducing that minimum from $25,000 to $2,000; brokers have a transition period through October 20, 2027 to implement the lower threshold. Check your broker's current requirement.

Portfolio DiversificationStocksCrypto

Spreading capital across assets that do not move in lockstep, so a loss in one is not fully mirrored across the whole portfolio; genuine diversification depends on real differences in risk drivers, not just holding more assets. Full guide →

Partial WithdrawalCrypto

An automatic withdrawal of validator balance above the required active stake amount while the validator remains active, subject to Ethereum protocol rules.

Passkey WalletCrypto

A wallet using device-backed passkey authentication, often combined with smart accounts or secure enclaves to simplify key management.

PassphraseCrypto

An optional additional secret combined with a seed phrase in some wallet standards to derive a different wallet, requiring exact recovery knowledge.

PaymasterCrypto

An ERC-4337 smart contract that can sponsor transaction fees or allow alternative fee-payment logic for user operations.

Peer DiscoveryCrypto

The methods nodes use to find other network participants so they can join and maintain a peer-to-peer network.

Permit SignatureCrypto

An off-chain signature authorizing a smart contract to spend tokens or perform an action without first sending a separate on-chain approval transaction.

Permit2Crypto

A reusable smart-contract permission system popularized by Uniswap for signed token approvals and transfers across applications, requiring careful allowance management.

Pool FeeCrypto

A fee retained by a mining or staking pool for coordinating participation and distributing rewards.

Pooled StakingCrypto

Combining stake from multiple users through a service or protocol to meet validator requirements or share rewards.

Private-Key BackupCrypto

A secure copy of the cryptographic secret or seed material needed to restore access to blockchain funds.

Probabilistic FinalityCrypto

A settlement model where confidence increases as more blocks build on a transaction rather than reaching a single deterministic finality event.

PruningCrypto

Deleting or compacting old blockchain data that is no longer required for a node's chosen validation or query role.

PseudonymousCrypto

Using a persistent identity or address that is not directly tied to a public legal name, common in blockchain communities and on-chain activity.

Peg DefenseCrypto

Protocol, issuer, or market actions intended to restore or preserve a pegged asset's target value.

Pre-Mine AllocationCrypto

The destination and proportions of a pre-created token supply assigned before open network participation.

Principal Token(PT) Crypto

A tokenized claim on the principal component of a yield-bearing asset, commonly created by splitting principal from future yield.

Private SaleCrypto

A token sale offered to a limited group of investors before or outside a broad public distribution.

Proxy ContractCrypto

A smart contract that delegates calls to separate implementation logic, commonly used to make applications upgradeable while preserving address and state.

Public SaleCrypto

A token offering made available to a broader set of eligible participants according to the issuer's rules and applicable law.

Partial LiquidationCrypto

Forced reduction of part of a leveraged position to restore margin compliance without immediately closing the entire position.

Percent Supply Last ActiveCrypto

The share of supply that last moved within or beyond a defined age window, used to study holding behavior.

Perp PremiumCrypto

The percentage difference between a perpetual contract's traded or mark price and its spot index or reference price.

Perpetual Funding(funding) Crypto

Periodic payments between long and short perpetual-contract traders intended to keep the contract price near the underlying reference market.

Portfolio DeltaCrypto

The net first-order sensitivity of a portfolio's value to changes in the underlying cryptoasset price.

Position RatioCrypto

A comparison of aggregate long and short position exposure, distinct from a ratio based only on the number of accounts.

Predicted Funding RateCrypto

A venue's estimate of the next funding rate based on current premium, interest, and contract-specific formulas.

Provably Lost CoinsCrypto

Assets sent to outputs or addresses that are cryptographically or logically unspendable under known protocol conditions.

Put/Call OI RatioCrypto

Put open interest divided by call open interest; interpretation requires context because positions may be hedges, spreads, or market-making inventory.

Put/Call Volume RatioCryptoOptionsStocks

Put option trading volume divided by call volume over a chosen period.

Paid ShillCrypto

A promoter compensated to market a cryptoasset or project, creating a conflict that should be disclosed where required.

Paper HandsCrypto

Internet slang criticizing someone for selling quickly under pressure or volatility.

PasskeyCrypto

A phishing-resistant credential based on public-key cryptography that can replace or supplement passwords for supported services.

Phishing-Resistant MFACrypto

Multi-factor authentication designed to prevent credential replay on fraudulent sites, typically using cryptographic origin binding.

Play-to-Earn(P2E) Crypto

A gaming model that rewards players with transferable tokens or digital assets for in-game activity.

Plutocratic GovernanceCrypto

A governance structure where voting influence is strongly proportional to wealth or token ownership.

PonzinomicsCrypto

PrintStocksCrypto

Trader shorthand for a reported trade or transaction at a specific price and size. Distinct from prints in the art market, which are artworks pulled from a matrix such as a plate, stone, screen or block.

Property AppreciationStocks

Property appreciation is the increase in a real estate asset's market value over time, typically driven by factors such as rising local demand, limited housing supply, inflation, neighborhood improvements, or broader economic growth. It represents one of the two primary sources of real estate investment return, alongside rental income, and is only realized as an actual gain when the property is sold or refinanced. Appreciation is not guaranteed (property values can also decline due to oversupply, economic downturns, or deteriorating local conditions), which is why real estate is generally considered a longer-horizon investment.

Probability of Profit (POP)(POP, Probability of Profit) Options

An estimate, derived from an option's implied volatility and the underlying's price distribution, of the statistical likelihood that a given options position will show a profit by expiration; it does not account for how large that profit or loss might be. Full guide →

Probability of TouchOptions

An estimate of the likelihood that the underlying price will touch a given strike at any point before expiration, rather than only at expiration; it is always higher than the probability of finishing beyond that strike, since price can touch a level and then reverse. Full guide →

Probability ITM(Probability In-the-Money) Options

An implied-volatility-based estimate of the likelihood that an option will finish in the money at expiration; delta is commonly used as a rough proxy for this probability, though the two are not mathematically identical. Full guide →

phillips curveStocksCrypto

An economic model describing an inverse relationship between inflation and unemployment (or economic slack more broadly): as unemployment falls and the labor market tightens, wage and price inflation are theorized to rise, and vice versa; the relationship has weakened and become less reliable in recent decades, but it remains a core reference point in how central banks think about the inflation-employment trade-off. Full guide →

potential GDPStocksCrypto

The maximum level of real economic output an economy can sustain over the long run without generating rising inflation, determined by the size of the labor force, capital stock, and productivity growth; it is a theoretical, unobservable benchmark estimated by economists and central banks, used to calculate the output gap and assess whether current growth is inflationary or not. Full guide →

Position Accountability LevelFutures

A threshold set by an exchange below the hard federal or exchange position limit at which a trader must be prepared to explain the size and purpose of a large position to the exchange, and may be required to reduce it, without automatically breaching a formal limit.

Pro-Rata AllocationOptionsFutures

A matching method that fills resting orders at a price level in proportion to their size rather than strictly by time priority, commonly used in options and futures markets to allocate trades among multiple market makers quoting the same price.

Primary Listing ExchangeStocks

PensionStocks

A retirement benefit, typically provided through a defined benefit plan, that pays a retiree a regular income stream for life based on years of service and final or average salary. Pensions have become less common in the private sector as employers have shifted toward defined contribution plans like the 401(k), though many government and union jobs still offer them.

Psychological Level(Round Number Level) StocksCrypto

A round, easy-to-remember price (such as $100, $50,000 for bitcoin, or a whole index number) where traders disproportionately cluster limit orders and stops, making it act as informal support or resistance even without a prior technical basis.

Positive Volume Index(PVI) StocksCrypto

A cumulative indicator that only adjusts on days when volume rises from the prior day, based on the theory that price changes on high-volume days reflect crowd-driven, less-informed activity.

Percent Above Moving Average(Percent of Stocks Above Moving Average) Stocks

A market breadth indicator that tracks the percentage of stocks within an index trading above a chosen moving average (commonly the 50-day or 200-day), used to gauge the overall health and participation of a market trend. Full guide →

public mempoolCrypto

The default, visible pool of pending transactions that have been broadcast to a blockchain's network but not yet included in a block, where anyone running a node can observe pending transaction details before they are confirmed. Full guide →

Publicly Traded REIT(exchange-listed REIT) Stocks

A publicly traded REIT is a REIT whose shares are listed and traded on a major stock exchange, such as the NYSE or Nasdaq, giving investors daily liquidity and transparent, market-set pricing. This distinguishes it from non-traded and private REITs, whose share prices are not continuously quoted and which are typically far less liquid.

Private REITStocks

A private REIT is a REIT that is not registered with the SEC for public trading and is instead sold through private placements, typically to accredited or institutional investors. Private REITs are illiquid, with no public market for shares and redemption terms set entirely by the sponsor, and they carry lighter public disclosure requirements than publicly traded REITs.

Property Tax(real estate tax, ad valorem tax) Stocks

Property tax is a recurring local tax levied on real estate ownership, typically calculated as a percentage (the mill rate or tax rate) of the property's assessed value and used to fund schools, infrastructure, and local government services. Assessed value and effective rates vary widely by state and county, and many jurisdictions offer reduced assessments for agricultural, timberland, or conservation-use land compared with land held for development, so owners should verify local rules before assuming a rate.

Patent RoyaltiesStocks

Patent royalties are payments made by a licensee to a patent holder for the right to make, use, or sell a patented invention, commonly structured as a percentage of the licensee's sales revenue or a fixed fee per unit sold. Because a U.S. utility patent's protection generally lasts 20 years from the filing date, patent royalty income streams have a finite, known horizon after which the invention enters the public domain and can be used by anyone without payment.

PatentStocks

A patent is a government-granted exclusive right that allows an inventor to prevent others from making, using, selling, or importing their invention for a limited period, generally 20 years from the filing date for a U.S. utility patent, in exchange for publicly disclosing how the invention works. Patents can be bought, sold, or licensed like other property, and investors can gain exposure to patent-derived income through licensing royalties or IP-backed financing without inventing anything themselves.

Public InfrastructureStocks

Public infrastructure is infrastructure owned, funded, or operated by government entities, such as public roads, municipal water systems, public transit, and government-owned airports, generally financed through taxes, government bonds (including municipal bonds), and user fees. Investors can gain exposure indirectly through municipal bonds or through public-private partnerships where a private operator manages a government-owned asset under contract.

Private InfrastructureStocks

Private infrastructure is infrastructure owned, financed, or operated by private companies or investment funds rather than government entities, including privately owned toll roads, cell towers, data centers, and pipelines, often held through private equity infrastructure funds, publicly traded infrastructure companies, or master limited partnerships. Private infrastructure investments often carry long-term contracted or regulated revenue, which supports steady cash flow, but access for individual investors is frequently limited to public infrastructure stocks, ETFs, or, for accredited investors, private infrastructure funds.

Ports(seaports) Stocks

Ports, as an infrastructure investment category, refers to ownership or operation of maritime shipping terminals that handle cargo and container traffic, generating revenue from berthing, cargo-handling, and storage fees. Port operators often hold long-term concessions (sometimes decades) from government port authorities, and revenue is closely linked to global trade volumes, giving ports meaningful exposure to international trade cycles alongside the high barriers to entry typical of infrastructure assets.

PlatinumStocksFutures

A rare precious metal used primarily in autocatalysts, jewelry, and industrial catalysis, with a much smaller investment market than gold or silver. Platinum's price is closely tied to automotive production (especially diesel vehicles) and mine supply concentrated in South Africa and Russia.

PalladiumStocksFutures

A rare precious metal used mainly in catalytic converters for gasoline vehicles, giving it one of the most concentrated end-use profiles of any traded metal. Palladium is mined mostly as a byproduct of platinum and nickel mining, primarily in Russia and South Africa, which makes its supply relatively inelastic to price.

Premium Over SpotStocks

The extra amount a buyer pays for a physical bullion product above the metal's underlying spot price, covering minting, distribution, dealer margin, and, in periods of high demand, scarcity of available inventory. Premiums vary by product type, size, and mint, and typically widen sharply during supply shortages or market stress.

Precious-Metals Fund(precious metals mutual fund) Stocks

A mutual fund or ETF that invests in a basket of precious-metals-related assets (typically mining and royalty company stocks, sometimes combined with physical bullion or futures), rather than a single metal or single miner. These funds offer diversified sector exposure but carry management fees and, unlike physical bullion, expose investors to broad equity-market risk.

Physical OwnershipStocks

Directly holding a tangible asset (bullion, a coin, a bottle of wine, a painting) in one's own possession or a segregated account, rather than owning a paper claim such as fund shares or a futures contract. Physical ownership eliminates counterparty and custodian risk but adds the practical burdens of storage, insurance, authentication, and typically wider bid-ask spreads on resale.

Physical Gold vs. Gold ETFStocks

A comparison between owning physical bullion directly and owning shares of a gold-backed ETF. Physical gold offers direct possession and no counterparty risk but requires storage, insurance, and wider dealer spreads; gold ETFs offer instant liquidity, low transaction costs, and easy portfolio integration but carry a small annual expense ratio, custodian counterparty exposure, and no ability to take physical delivery for most retail-sized holdings.

Precious Metals IRA(Gold IRA, self-directed precious metals IRA) Stocks

A self-directed IRA that holds physical gold, silver, platinum, or palladium instead of, or alongside, stocks and funds. Internal Revenue Code Section 408(m) treats most metals and coins as non-deductible collectibles, which trigger an immediate taxable distribution if an IRA acquires them, but it carves out an exception for gold, silver, platinum, and palladium bullion meeting specific fineness standards, plus certain government-minted coins, provided a bank or IRS-approved non-bank trustee keeps physical possession of the metal. Full guide →

ProvenanceStocks

The documented ownership and exhibition history of a collectible item, tracing it back through prior owners, dealers, and institutions. Strong, unbroken provenance supports both authenticity and value, while gaps in provenance raise the risk that an item is a forgery, stolen, or improperly exported.

Primary Art MarketStocks

The market in which artwork is sold for the first time, typically directly from the artist through a gallery, at prices generally set by the gallery rather than by open bidding. Primary-market prices are more predictable but less market-tested than secondary-market (resale) prices, since the work has no prior sale history to benchmark against.

Pipeline(Pipelines) Stocks

Fixed infrastructure that transports crude oil, natural gas, or refined products over land, typically operated by midstream companies under long-term contracts or regulated tariffs. Pipeline economics are generally driven by contracted volumes and regulated or negotiated fee rates rather than the spot price of the commodity flowing through them. Many United States pipeline operators are structured as master limited partnerships, which pass income through to unit holders and avoid entity-level tax as long as at least 90% of gross income comes from qualifying sources, including transportation of certain fuels.

profit-sharing planStocks

A defined contribution retirement plan in which the employer makes discretionary contributions to employee accounts, often based on company profitability, with no obligation to contribute in a given year. Contributions can be allocated by a fixed formula or a more flexible age-weighted or new-comparability formula, and the plan can be combined with a 401(k) as a single plan design.

plan administratorStocks

The person or entity named in a retirement plan's governing documents responsible for day-to-day plan operations, including complying with ERISA's reporting, disclosure, and fiduciary duties, interpreting plan terms, and making distribution and eligibility determinations. The plan administrator is often, but not always, the employer or plan sponsor itself, and it can face personal liability under ERISA for breaches of fiduciary duty.

plan sponsorStocks

The employer, or for a multiemployer plan, the union or association, that establishes and maintains a retirement plan for its employees or members. The plan sponsor makes the underlying design decisions, including contribution formulas, investment lineup, and eligibility rules, and is legally distinct from the plan administrator, though the same entity often fills both roles at smaller companies.

premature distributionStocks

The IRS's formal term for a taxable retirement-account withdrawal taken before the qualifying age, reported on Form 1099-R with a distribution code that triggers the 10% early-withdrawal penalty unless the taxpayer can claim a recognized exception on Form 5329. It is functionally synonymous with "early withdrawal" but is the terminology used in IRS tax reporting and instructions.

pro-rata ruleStocks

An IRS rule under Internal Revenue Code §408(d)(2) that treats all of a taxpayer's traditional, SEP, and SIMPLE IRAs as a single aggregated account when determining how much of any distribution or Roth conversion is taxable, based on the ratio of after-tax basis to the total combined balance across all those accounts as of year-end. It prevents someone from selectively converting only after-tax, nondeductible dollars while leaving pre-tax dollars behind, which is why the pro-rata rule can create an unexpected tax bill on a backdoor Roth conversion if the person also holds pre-tax IRA balances.

prepaid tuition planStocks

A type of 529 plan that lets a purchaser lock in current tuition rates at eligible in-state public colleges by prepaying future tuition credits, shifting the risk of tuition inflation to the plan rather than the family. Prepaid plans are less flexible than standard 529 savings plans (many are limited to in-state public schools or require adjustment if the beneficiary attends a private or out-of-state school), and several states have closed their prepaid plans to new enrollment.

policy loanStocks

A loan a life insurance policyholder takes against their permanent policy's cash value, which does not require credit approval and has no fixed repayment schedule, but which accrues interest and reduces the death benefit by the outstanding loan balance if not repaid before the insured's death. An outstanding loan that grows larger than the cash value can cause the policy to lapse, which can trigger an unexpected taxable event on the gain portion of the loan that was never repaid.

participating policyStocks

A life insurance policy, typically whole life issued by a mutual insurer, that entitles the policyholder to share in the insurer's divisible surplus through non-guaranteed annual dividends, which can be taken as cash, used to reduce premiums, left to accumulate with interest, or used to purchase additional paid-up insurance. Dividends are not guaranteed and depend on the insurer's actual mortality, expense, and investment experience relative to what was assumed when pricing the policy.

payable on death(POD) Stocks

A beneficiary designation on a bank account, such as checking, savings, or a CD, that functions like a transfer-on-death designation for securities: the named beneficiary receives the account funds directly upon the owner's death without going through probate. Like TOD, a POD designation takes precedence over a will's instructions for that specific account, a common source of unintended results when a will and beneficiary designations aren't kept consistent.

probateStocks

The court-supervised legal process of authenticating a will, or applying intestacy law if there is none, paying the deceased's debts and taxes, and distributing the remaining assets to heirs or beneficiaries. Probate can be time-consuming and public, which is why many estate plans use tools like trusts, transfer-on-death designations, and joint ownership to move assets outside the probate process.

putable bondStocks

A putable bond gives the bondholder, rather than the issuer, the right to force the issuer to repurchase the bond at a predetermined price before maturity, typically on specified dates. Investors exercise this put option when interest rates rise and the bond's fixed coupon becomes less attractive relative to newly issued bonds, or when the issuer's credit quality deteriorates. Because this feature benefits the investor, putable bonds generally offer lower yields than otherwise comparable non-putable bonds.

preferred ETFStocks

A preferred ETF is an exchange-traded fund that holds a diversified basket of preferred stocks, giving investors exposure to preferred dividend income and price movements without needing to select and hold individual preferred issues. Because many preferred stocks are issued by banks and insurers, preferred ETFs are often concentrated in the financial sector, which adds sector-specific risk relative to a broadly diversified bond fund. Preferred ETF prices are sensitive to interest-rate changes and issuer call risk in much the same way individual preferred shares are, though the fund itself smooths out single-issuer credit risk through diversification.

principal-protected note(PPN) Stocks

A principal-protected note is a structured note designed to return the investor's full original principal at maturity, regardless of how the underlying reference asset performs, while offering some participation in the asset's upside. This protection is not insured by the FDIC or SIPC; it is a promise backed solely by the issuing bank's creditworthiness, so if the issuer defaults, the investor can still lose principal. Principal protection typically comes at the cost of capped or reduced upside participation and requires the investor to hold the note to maturity, since selling early exposes the note to market price fluctuation with no protection guarantee.

passive incomeStocks

Passive income is earnings received from an investment, business, or asset that requires little to no ongoing active effort to maintain, as distinguished from earned income from a job. In an investing context, common sources include dividends, bond interest, REIT distributions, and rental income, all of which continue to be generated without the investor performing regular work in exchange. The IRS uses a narrower legal definition of 'passive income' for tax purposes, generally limited to rental activity and business income in which the taxpayer does not materially participate; portfolio income like dividends and interest is technically classified separately even though it is commonly described as passive in everyday use.

preferred dividendsStocks

Preferred dividends are the fixed or floating periodic payments made to holders of preferred stock, which must generally be paid before any dividend can be distributed to common shareholders. Unlike bond interest, preferred dividends are not a contractual obligation the issuer must pay to avoid default; a company can suspend them during financial stress, though cumulative preferred structures require missed dividends to be made up before common dividends resume. Many preferred dividends qualify for preferential qualified-dividend tax treatment if IRS holding-period requirements are met, unlike most bond interest.

purchasing powerStocks

Purchasing power is the quantity of goods and services that a given amount of money can buy, which erodes over time as inflation raises the general price level. An investment return that fails to outpace inflation results in a loss of real purchasing power even if the nominal account balance grows, which is why long-term investors distinguish between nominal returns (unadjusted) and real returns (inflation-adjusted). Holding too much wealth in cash or low-yielding fixed-rate instruments over long periods is a common way purchasing power is eroded without an investor necessarily noticing, since the account balance itself never falls.

private equity(PE) Stocks

An asset class where investment firms raise pooled capital from institutions and high-net-worth investors to acquire equity stakes in private companies, or take public companies private, aiming to improve operations and exit through a sale or IPO. Private equity funds are typically structured as closed-end limited partnerships with 10-year-plus lifespans and are illiquid relative to public markets. Full guide →

portfolio companyStocks

A company in which a private equity fund, venture capital fund, or other investment vehicle holds an equity stake as part of its investment portfolio. The fund typically takes an active role in a portfolio company through board seats, operational guidance, or strategic direction, aiming to grow its value before an eventual exit.

pre-seed(pre-seed round) Stocks

The earliest stage of startup fundraising, typically used to build an initial product or validate a business idea before a company has meaningful revenue or traction. Pre-seed rounds are usually funded by founders, friends and family, and angel investors, often using SAFEs or convertible notes rather than a priced equity round.

pro rata rights(pro-rata rights) Stocks

A contractual right allowing an existing investor to participate in a company's future financing rounds in proportion to their current ownership percentage, protecting them from dilution as the company raises more capital. Pro rata rights are common terms for early investors, including seed funds and angels, to maintain their stake in successful startups through later rounds.

private credit(private debt) Stocks

Non-bank lending to companies, arranged directly between a borrower and private lenders such as credit funds, business development companies, or institutional investors, rather than through syndicated bank loans or public bond markets. Private credit has grown rapidly since the 2008 financial crisis as banks pulled back from leveraged and middle-market lending, leaving asset managers to fill the gap. Full guide →

P2P lending(peer-to-peer lending) Stocks

A form of lending in which individual or institutional investors fund loans to borrowers directly through an online platform that matches supply and demand for credit, bypassing traditional bank balance sheets. Investors typically buy fractional interests, called notes, in individual consumer or small-business loans and earn interest as borrowers repay.

pipeline assetStocks

Midstream energy infrastructure (such as pipelines, storage terminals, and processing facilities) that transports or handles oil, natural gas, or refined products, typically owned by master limited partnerships. Pipeline assets often generate relatively stable, fee-based revenue tied to throughput volumes under long-term contracts, rather than direct exposure to commodity prices.

precious metalsStocks

Physical metals such as gold, silver, platinum, and palladium held as an alternative investment for their perceived store-of-value characteristics and historical role as an inflation hedge and safe haven during periods of economic or geopolitical stress. Investors can gain exposure through physical bullion, futures, or exchange-traded products backed by the metal.

Positive Screening(best-in-class screening) Stocks

An ESG methodology that selects companies with strong ESG performance relative to industry peers, rather than excluding whole sectors outright. A 'best-in-class' energy fund, for example, might still hold oil and gas companies if they rank favorably on environmental and safety practices compared to competitors in the same industry.

Proxy VotingStocks

The exercise of a shareholder's voting rights on corporate matters (board elections, executive pay, mergers, and shareholder proposals), typically delegated to the fund manager for shares held inside a mutual fund or ETF. Fund managers must disclose their proxy voting records, and voting policy has become a key stewardship and ESG lever, especially for large passive managers who cannot vote with their feet by selling.

Passive FundStocks

A mutual fund or ETF designed to replicate the holdings and weights of a specified index rather than have a manager pick securities, aiming to match the index's return rather than beat it. Passive funds typically charge much lower expense ratios than active funds because they require far less research and trading activity.

Passive InvestingStocks

An investment strategy built around buying and holding a broad, diversified basket of securities (typically via an index fund or ETF), rather than trying to pick winning stocks or time the market. Passive investing generally produces lower costs and turnover than active investing, and by design it will match, not beat, its benchmark's return before fees.

Profitability Factor(RMW, robust minus weak) Stocks

A factor from Fama and French's five-factor asset pricing model (denoted RMW, for 'robust minus weak') that captures the historical tendency of stocks with high operating profitability to outperform stocks with low operating profitability. Operating profitability is defined as revenue minus cost of goods sold and operating/interest expenses, divided by book equity, a measure closely related to, but distinct from, the separate 'quality' factor used in many commercial factor products. Full guide →

Pip(Percentage in Point, Price Interest Point) Stocks

A pip is the smallest standardized price movement in a forex quote, conventionally the fourth decimal place for most currency pairs (or the second decimal place for pairs involving the Japanese yen). Pips are the standard unit traders use to measure price changes and calculate gains, losses, and position sizing.

Portfolio InsuranceOptions

Portfolio insurance is a hedging approach designed to protect a portfolio's value against significant declines while preserving upside participation, historically implemented using protective puts or dynamic strategies that increase hedges as prices fall. The term is closely associated with dynamic, rules-based hedging programs used by institutional investors in the 1980s, whose synchronized selling is widely cited as a contributing factor to the severity of the October 1987 stock market crash.

Portfolio OptimizationStocks

Portfolio optimization is the process of selecting the mix of assets that is expected to deliver the highest return for a given level of risk, or the lowest risk for a given expected return, based on modern portfolio theory. It typically uses quantitative models incorporating expected returns, volatility, and correlations between assets to identify an 'efficient' portfolio on the risk-return frontier. Full guide →

Political RiskStocks

Political risk is the risk that changes in government policy, regulation, leadership, or political stability will negatively affect the value of an investment. It ranges from tax and regulatory changes in stable democracies to expropriation, capital controls, or civil unrest in less stable countries, and is a key consideration in international and emerging-market investing.

Price-weighted indexStocks

A price-weighted index assigns weights based on component share prices rather than market capitalization, so higher-priced stocks have greater mathematical influence.

Proprietary Trading(prop trading) StocksCrypto

Proprietary trading is a firm dealing in securities, derivatives or currencies with its own capital to earn profit for itself rather than filling client orders for a fee. The desk keeps the entire gain and absorbs the entire loss, so results land in trading revenue instead of commission revenue. In the United States the Volcker Rule restricts short-term proprietary positions at banking entities that hold insured deposits, which pushed much of the activity toward hedge funds and independent trading firms. Market making, hedging and underwriting activity are treated separately from it.

Purchase Money Security Interest(PMSI) Stocks

A purchase money security interest is a lien a lender or seller takes in the very goods whose purchase it financed. Under Article 9 of the Uniform Commercial Code it can outrank an earlier blanket lien on the same collateral class, provided the creditor perfects it within the statutory window and, for inventory, notifies existing secured parties beforehand. That super-priority is why equipment vendors and floor-plan lenders will finance a borrower who has already pledged substantially all assets to a bank.

paper swapFuturesStocks

A paper swap is a commodity swap settled entirely in cash against a published price index, with no obligation to deliver or receive the physical commodity. One side pays a fixed price and receives the floating index average over the settlement period, the other side takes the opposite leg, and only the difference changes hands. Producers and consumers use it to lock in a price while continuing to buy or sell physical barrels or cargoes separately through their normal supply channels.

People's Bank of China(PBOC) StocksCrypto

The People Bank of China is the central bank of the People Republic of China, responsible for issuing the renminbi, conducting monetary policy, managing the country foreign exchange reserves and overseeing the payment system. It operates under the State Council rather than as an independent institution, and it uses a broader toolkit than most peers, including reserve requirement ratios, targeted lending facilities, window guidance to banks and a daily reference rate that anchors onshore currency trading within a permitted band.

perpetual debtStocks

Perpetual debt pays interest indefinitely and has no scheduled maturity date at which principal is repaid. Investors recover capital only by selling in the market or if the issuer exercises a call, which such issues normally allow after a set number of years. With no redemption date, the price is unusually sensitive to changes in yield and to the credit standing of the issuer. Banks issue perpetual instruments to meet regulatory capital rules, and those versions typically add loss absorption features such as coupon cancellation.

perpetual preferred stockStocks

Perpetual preferred stock pays a fixed or floating dividend with no maturity date, ranking ahead of common shares for dividends and in liquidation but behind every class of debt. Dividends may be cumulative, meaning missed payments accrue and must be cleared before common dividends resume, or non-cumulative, meaning a skipped payment is gone. Issuers usually retain a call right after an initial period. Because the cash flow resembles a bond without redemption, the price moves with long-term interest rates as well as with issuer credit.

poolStocks

A pool is a group of individual loans or receivables assembled and held together so that the cash they generate can back a single security. In agency mortgage lending, hundreds of home loans with similar coupons and maturities are combined and a pass-through certificate is issued against them, giving each holder a proportional share of the principal and interest collected. Pooling diversifies the idiosyncratic risk of any one borrower and creates an instrument large and standardized enough to trade.

putable convertible bondStocks

A putable convertible bond gives its holder two separate rights: to convert into a fixed number of the issuer shares, and to sell the bond back to the issuer at a set price on specified dates. The conversion right supplies equity upside while the put establishes a floor and shortens the effective maturity, since the holder can walk away if the shares disappoint or credit weakens. The issuer pays for both features with a lower coupon, and must plan for the cash needed if the put is exercised.

Plaza AccordStocksFutures

The Plaza Accord was the September 1985 agreement among finance officials of the United States, Japan, West Germany, France and the United Kingdom to bring down the value of the dollar through coordinated intervention in currency markets. The dollar had appreciated sharply in the early 1980s, hurting American exporters and fueling protectionist pressure. The dollar fell substantially against the yen and the deutsche mark over the following two years, and the subsequent Louvre Accord of 1987 sought to halt the decline.

price-weighted averageStocks

A price-weighted average adds the prices of its constituents and divides by a divisor, so a high-priced share influences the index more than a low-priced one regardless of company size. The Dow Jones Industrial Average and the Nikkei 225 are built this way. The divisor is adjusted whenever a stock splits or a constituent is replaced, so that the mechanical change does not alter the index level. Critics note that a share split reduces a company influence without changing anything about the business.

Par Yield CurveStocks

A par yield curve plots, for each maturity, the coupon a newly issued bond would need to carry in order to trade exactly at face value. Because such a bond has no discount or premium to amortize, its coupon equals its yield to maturity, which makes the curve the natural reference for pricing new issues and for quoting swap rates. It is derived from observed market prices and is mathematically related to the zero coupon and forward curves, each of which describes the same term structure from a different angle.

ParityStocks

Parity means two values are equal, and the specific sense depends on the market. A convertible bond is at parity when its market price equals the value of the shares it converts into. A currency is at parity with another when one unit buys exactly one unit. Put call parity is the arbitrage relationship linking the prices of a put, a call, the underlying and a bond of the same maturity. In each case the term marks the point at which a comparison balances rather than favoring one side.

Parity PriceStocks

Parity price is the price at which two instruments are equivalent in value. For a convertible bond it is the conversion ratio multiplied by the current share price, which is what the bond would be worth if converted immediately, and the amount by which the bond trades above it is the conversion premium. In agricultural policy the term has a separate historical meaning: the price that would give farmers the same purchasing power for their output as in a designated base period.

Participatory Note(P-Note) StocksFutures

A participatory note is a derivative issued offshore by a registered foreign investor in India that passes the economic return of an underlying Indian security to a holder who is not registered locally. The registered institution buys the share and issues the note, so the beneficial owner gains exposure without completing local registration. Because that structure obscures who ultimately holds the position, Indian regulators have tightened know-your-customer and reporting requirements and restricted the use of such notes for speculative derivative positions.

Plunge Protection Team (PPT)(Working Group on Financial Markets) StocksCrypto

Plunge Protection Team is the informal nickname for the Working Group on Financial Markets, created by executive order in March 1988 after the October 1987 stock market crash. It is chaired by the Secretary of the Treasury and includes the chairs of the Federal Reserve Board, the Securities and Exchange Commission and the Commodity Futures Trading Commission, with a mandate to advise on market integrity and investor confidence. The nickname comes from a 1997 newspaper column, and the group has no public trading mandate or disclosed balance sheet.

Post-Money ValuationStocks

Post-money valuation is what a company is deemed to be worth immediately after a financing round closes, equal to the agreed pre-money value plus the new cash raised. Dividing the investment by the post-money figure gives the percentage of the company the new investors own. The headline number is easy to overstate, because option pool expansion, liquidation preferences and anti-dilution terms all change the economics without changing the stated valuation, so the preference stack matters as much as the number itself.

Price to Tangible Book ValueStocks

Price to tangible book value compares the share price with book equity after removing goodwill and other intangible assets, leaving only assets with a physical or contractual form. It is used most in banking and insurance, where the balance sheet is largely financial and carried close to fair value, and it strips out the goodwill created by past acquisitions that would not survive a liquidation. For asset-light businesses whose value rests on brands and software the measure is close to meaningless.

Price-to-Book RatioStocks

The price to book ratio divides the share price by book equity per share, comparing what the market pays with what the accounts say the owners contributed and retained. A ratio below one signals that the market expects the assets to earn less than their carrying value or doubts the carrying value itself. Its usefulness depends on how closely the accounts track economic reality, so it works better for banks and property companies than for firms whose main assets are research, brands and people that accounting never capitalizes.

Principal, Interest, Taxes, Insurance(PITI) Stocks

Principal, interest, taxes and insurance are the four components of a typical monthly housing payment on a mortgaged home. Principal repays the loan balance, interest is the cost of the borrowing, taxes are the property levy collected by local government and insurance covers the building, with mortgage insurance added when the down payment is small. Lenders often collect the tax and insurance portions into an escrow account and pay the bills as they fall due, and they use the total against income when testing affordability.

Private BankingStocks

Private banking is the delivery of banking, credit and investment services to wealthy clients through a dedicated relationship manager, usually above a stated minimum of investable assets. Services extend beyond deposits and portfolio management to lending against securities and property, trust and estate structuring, philanthropic advice and coordination with the client tax and legal advisers. Revenue comes from a mixture of fees on assets, spreads on lending and product commissions, and disclosure of how the bank is paid is a recurring supervisory focus.

physical deliveryOptionsStocks

Settlement of a derivatives contract by transferring the actual underlying commodity or security instead of exchanging cash for the price difference. Exchange rules define deliverable grades, approved warehouses or delivery points, and the notice and delivery dates. Speculative positions are usually closed before the notice period precisely to avoid the obligation, leaving the mechanism to commercial participants who genuinely want the goods or can supply them.

premium to NAVStocks

The amount by which a fund's market price exceeds the per-share value of its holdings, quoted as a percentage of net asset value. It appears mainly in closed-end funds and exchange-traded products with limited or suspended creation, because a fixed share count means demand moves the price without changing the portfolio. When price sits below net asset value the same measure is a discount, and both can persist for long periods.

price-to-earningsStocks

A valuation multiple dividing share price by earnings per share, expressing the price paid for each unit of annual profit. Trailing versions use reported earnings from the last twelve months and forward versions use analyst estimates, so the two are not comparable with each other. The multiple is meaningless when earnings are negative, and it shifts with accounting choices, leverage, and expected growth rather than with value alone.

prime money market fundStocks

A money market fund permitted to hold short-term corporate and bank debt such as commercial paper and certificates of deposit alongside government paper. That credit exposure brings a modestly higher yield than a government fund and adds issuer risk. Under Securities and Exchange Commission rules, institutional prime funds price at a floating net asset value and prime funds can apply liquidity fees when redemptions are heavy.

PRIIPsStocks

Packaged retail and insurance-based investment products: a European Union and United Kingdom regulatory category covering investments whose return depends on a wrapper or on reference values rather than on directly held securities, including funds, structured products, and unit-linked insurance. Manufacturers must publish a short standardized key information document setting out the product, its risk on a common indicator scale, performance scenarios, and aggregate costs so retail buyers can compare.

PRIIPs Key Information DocumentStocks

The Key Information Document required under the European packaged retail and insurance-based investment products regulation is a short, standardized disclosure that must be given to a retail investor before they buy an in-scope product. Its length, headings and order are prescribed so that competing products can be compared directly. It carries a summary risk indicator on a fixed scale, performance scenarios prepared by a set methodology, a breakdown of costs including their effect on return over stated holding periods, and details of how to complain.

Parametric TriggerStocks

A parametric trigger determines whether a contract pays out by reference to a measured physical parameter rather than to the loss actually suffered. The contract names the index (wind speed at a location, earthquake magnitude and depth, rainfall over a period, river gauge height), the threshold, and the amount payable at each level. Because settlement needs only the published measurement, payment is fast and loss adjustment is unnecessary. The trade-off is basis risk: an event can cause severe damage without crossing the threshold, or cross it while causing little.

Performance RoyaltyStocks

A performance royalty is owed to the songwriter and the music publisher whenever a composition is performed publicly: broadcast on radio or television, streamed, played in a venue, or used in a business. Performing rights organizations license users on a blanket basis, monitor or sample usage, and distribute the collected money to their writer and publisher members under a published distribution rule. It is separate from the mechanical royalty owed for making copies, and separate again from any payment owed to the owner of the sound recording.

Performing Mortgage NoteStocks

A performing mortgage note is a mortgage loan whose borrower is paying on schedule. Investors buy such notes for the contracted interest income, at a price reflecting the note rate against current market rates, the seasoning and payment history, the remaining term, and the equity cushion between the balance and the property value. The main risks are prepayment, which ends the income early when rates fall, and a later default that turns the position into a nonperforming note requiring workout or foreclosure.

Population ReportStocks

A population report is a running census published by a third-party grading company showing how many examples of a given collectible it has certified at each grade. Collectors use it to judge relative scarcity: a card or coin with very few examples at the top grade commands a premium over one with hundreds. The figure is not a true supply count, because it covers only items submitted to that company, counts resubmissions of the same item more than once, and cannot include examples still held ungraded.

Portfolio Investment EntityStocksCrypto

A Portfolio Investment Entity is a New Zealand tax classification for a fund that elects into a regime under which investment income is taxed at each investor's own prescribed investor rate rather than at the entity's rate. The investor supplies that rate to the fund, the fund calculates and pays tax on their share of income, and for most investors the resulting tax is final, so the income is not taxed again in their own return. The regime also changes how certain offshore share investments are taxed inside the fund.

Premium DomainStocks

A premium domain is an internet address whose string itself carries commercial value, typically because it is a short dictionary word, an exact-match commercial keyword, or a memorable brandable term on a widely recognized extension. Some are held by investors and offered on the secondary market at negotiated prices; others are reserved by the registry operator and sold at a higher initial registration fee, sometimes with a recurring premium renewal price that continues for as long as the name is held. Trademark conflict is the main legal exposure.

Private Mortgage NoteStocks

A private mortgage note is a real estate loan made by an individual or a non-bank entity rather than by a regulated institution, evidenced by a promissory note and secured by a mortgage or deed of trust. It arises when a seller finances part of the purchase price for a buyer, or when a private lender funds a borrower who cannot obtain bank credit. Terms are negotiated directly, so rate, amortization, balloon date and remedies vary widely, and the note can be sold on at a price reflecting its payment record.

Public Provident FundStocks

The Public Provident Fund is a long-term savings scheme backed by the Government of India, opened at banks and post offices, in which deposits accumulate at an interest rate the government announces periodically. It runs for a fixed initial term that can be extended in further blocks, with partial withdrawal and loan facilities allowed only after specified years. Contributions, accrued interest and the maturity amount receive favorable treatment under Indian income tax law, and annual deposit minimums and maximums are set by the government.

Publishing RoyaltyStocks

A publishing royalty is income earned from the underlying musical composition, the words and music, as opposed to any particular recording of it. It reaches the songwriter and the music publisher through several channels: mechanical royalties for reproductions, performance royalties for public performance and broadcast, and synchronization fees for use with visual media. The publisher administers the copyright, registers the work with collection societies, licenses it and pursues payment, keeping an agreed share. In book publishing the same phrase means an author's contractual share of sales revenue.

Portfolio of Financial AssetsStocks

A portfolio of financial assets is the complete set of securities, deposits, funds and derivative positions held by an investor, considered together rather than one at a time. The point of the grouping is that risk and return are properties of the combination: assets whose prices do not move in lockstep offset part of each other's variability, so total volatility is generally lower than the average volatility of the pieces. Analysis therefore centers on weights, correlations and aggregate exposures rather than on the merits of any single position.

Pre-IPOStocks

Pre-IPO describes the period and the transactions that occur before a private company lists its shares publicly. Pre-IPO shares are bought from the company in late-stage private rounds, or from existing employees and early investors through secondary transactions, usually at a valuation set by negotiation rather than by a market price. Such holdings are illiquid, often restricted by transfer approval rights and by a lock-up after any listing, and financial disclosure is limited compared with a listed company, so pricing rests on incomplete information.

paintingsStocks

Paintings are unique works in paint on canvas, panel, or paper, and they anchor the fine art market because each is a single object rather than one of an edition. Price depends on the artist's auction record, the period and subject within that artist's output, size, medium, condition and restoration history, exhibition record, and unbroken provenance. Authentication rests on inclusion in a catalogue raisonne, expert committees, and technical analysis. Transaction costs are high once buyer's premium, seller's commission, insurance, storage, and conservation are counted, and sales are infrequent.

parallelsStocks

Parallels are alternate versions of a base trading card that share the same photograph and design but differ in a distinguishing feature such as border color, foil pattern, or refractor finish, and are produced in smaller quantities than the base card. Sets are usually tiered, each successive parallel scarcer than the last, with the rarest limited to a handful of copies or a single one-of-one. Scarcity is often stated by serial numbering printed on the card. Because the image is identical, price differences between parallels come almost entirely from print run.

parkingStocks

Parking assets are garages and surface lots operated as income property, earning revenue from transient hourly parking, monthly contracts with nearby employers and residents, and event pricing. Operating costs are low relative to other property types and structures need little tenant improvement capital, but income is tied closely to activity in the surrounding buildings and to commuting patterns. Ownership models range from direct operation to leasing the facility to a parking operator for fixed rent. Long-term demand is exposed to transit investment, remote work, and changes in vehicle ownership.

participation ratesStocks

In a structured product or indexed annuity, the participation rate is the percentage of a reference index's gain that is credited to the contract. If an index rises ten percent over the measurement period and the participation rate is seventy percent, seven percent is credited before any cap or spread is applied. The issuer sets it from the cost of the options used to build the payoff, so participation falls when volatility and option costs rise or when interest rates leave a smaller budget for the option package. It is normally reset at each term renewal. Distinct from the participation rate of an execution algorithm, which is its share of total market volume over a period.

partnershipsStocks

A partnership is a business owned by two or more persons that is generally treated as a pass-through for tax purposes, meaning income, deductions, and credits flow to the partners and are reported on their own returns rather than taxed at the entity level. In a general partnership every partner shares management and unlimited liability. In a limited partnership, general partners manage and bear unlimited liability while limited partners contribute capital, risk only their investment, and stay out of management. The partnership agreement governs allocations, distributions, transfers, and dissolution.

pastureStocks

Pasture is agricultural land maintained in grass or forage for grazing livestock rather than for cultivated crops. Its productive capacity is measured as carrying capacity, commonly expressed in animal unit months per acre, which depends on rainfall, soil, forage species, and management practices such as rotational grazing. Because pasture generates less revenue per acre than irrigated cropland, its value per acre is usually lower and is influenced strongly by water availability, fencing and handling infrastructure, and whether the parcel carries development, recreational, or conservation value beyond grazing.

permanent cropsStocks

Permanent crops are agricultural plantings that live for many years and yield repeated harvests from the same trees or vines, including almonds, citrus, apples, olives, and wine grapes. They require substantial capital before the first commercial crop, produce rising yields as the planting matures, then decline and need replanting, so a property's value depends on the age distribution across its blocks. Because the planting cannot be changed between seasons, growers cannot rotate away from a weak price, and secure long-term water rights are usually the binding constraint on value.

photographyStocks

Photography as a collecting field values prints as physical objects, so the same image can be worth very different amounts depending on which print is offered. Determinants include whether it is a vintage print made near the time of the negative or a later print, the process used, size, edition size, whether the photographer signed and dated it, condition, and provenance. Because negatives and files can yield further prints, edition control and estate policy materially affect scarcity. Light exposure and humidity degrade many processes, so storage and display practice influence long-term condition.

physical commodity ownershipFuturesStocks

Physical commodity ownership is holding the actual raw material, most often precious metals in bar or coin form, rather than taking exposure through futures, funds, or producer shares. It removes futures roll and fund counterparty exposure but introduces costs that paper exposure does not carry: storage and insurance, assay and authentication on resale, wide dealer bid-ask spreads, transport, and in some jurisdictions sales tax on purchase. Allocated storage assigns specific identified bars to the owner, while unallocated holdings are a claim on a pool and rank as a creditor of the custodian.

platform riskStocksCrypto

Platform risk is the exposure created when an asset's revenue or accessibility depends on a third-party service the owner does not control, such as a search engine, app store, social network, marketplace, or investment platform. A change in ranking algorithm, fee schedule, policy, or account status can cut or eliminate income without any change in the underlying business. It also covers operational failure of the platform itself, including outages, insolvency, and loss of custody or records. Mitigation focuses on diversifying traffic sources, owning the customer relationship directly, and keeping independent records.

premiumsStocks

In physical metal and coin markets, the premium is the amount charged above the melt value of the metal an item contains, quoted in currency or as a percentage of spot. It covers fabrication, distribution, dealer margin, and any collector demand for the specific product. Premiums vary by product and shift with retail demand: small bars and popular sovereign coins carry higher premiums than large bars, and premiums can widen sharply when retail buying surges. Buyers pay the asking premium and typically sell into a lower bid premium, so the round trip cost is the spread between them. Distinct from an option premium, which is the price an option buyer pays for the rights the contract conveys.

prepaymentStocks

Prepayment is the repayment of loan principal ahead of the scheduled amortization, arising when a borrower refinances, sells the underlying property, makes extra payments, or defaults and has the loan liquidated. For an investor in loan-backed bonds it shortens the life of the investment and returns cash that must be reinvested, usually at the lower rates that prompted the refinancing in the first place. Speeds are quoted with conventions such as the conditional prepayment rate, the annualized share of a pool expected to repay early. Lockouts, yield maintenance, and penalties are used to limit it.

printsStocks

Prints are artworks made by transferring an image from a matrix such as a plate, stone, screen, or block onto paper, so multiple originals exist from the same work. Techniques include etching, lithography, screenprint, and woodcut, and each impression is an original rather than a reproduction. Value depends on the artist, the edition size, whether the impression is early in the run, signature and numbering, the state of the image, paper and margins, and condition including fading and foxing. Later restrikes made after the artist's involvement ended trade at large discounts. Distinct from a print in trading, which is trader shorthand for a reported trade at a specific price and size.

private fundsStocks

Private funds are pooled investment vehicles offered without a public registration, sold only to investors who meet wealth or sophistication standards set by securities regulators, and therefore subject to lighter disclosure than a registered fund. The category includes hedge funds, private equity, venture capital, private credit, and real assets vehicles. Common features are limited liquidity through lock-ups and redemption gates or a fixed fund life, valuation of holdings by the manager or a third party rather than by continuous market pricing, and fee terms combining a management fee with a share of profits.

private notesStocks

Private notes are debt instruments issued directly by a borrower to one or a small number of lenders without a public offering or exchange listing. Interest rate, payment schedule, collateral, covenants, and default remedies are negotiated in the note and any accompanying security agreement rather than set by market convention. Because no trading market exists, the lender expects to hold to maturity and prices the loan for illiquidity as well as credit. Enforcement depends on documentation quality, properly perfected security interests, and the borrower's willingness and ability to pay.

probabilityStocksCrypto

Probability is a number between zero and one expressing how likely an outcome is, where zero means it cannot occur and one means it is certain. It can be estimated from the observed frequency of an event across many repetitions, or assigned as a degree of belief that is updated as evidence arrives. In investing it combines with payoffs to give expected value, the sum of each outcome multiplied by its probability. Probabilities implied by option prices are risk-neutral rather than real-world, so they embed compensation for risk and should not be read as forecasts.

project financeStocks

Project finance funds a specific asset, such as a power plant, toll road, pipeline, or renewable installation, through a standalone entity whose debt is repaid from the cash the project itself generates. Lenders have limited or no recourse to the sponsors' balance sheets, so they underwrite contracted revenue: offtake agreements, availability payments, or long-term supply contracts. The structure relies on security over project assets and accounts, a defined payment waterfall, reserve accounts, and covenants such as a minimum debt service coverage ratio. Construction risk is usually transferred through fixed-price turnkey contracts.

proofStocks

A proof is a coin struck by a specialized process for collectors rather than for circulation, using polished dies and blanks and multiple strikes at higher pressure to produce sharp detail and, commonly, mirrored fields against frosted devices. Mints sell them directly in packaging at a premium to face and to bullion value. The word describes the method of manufacture, not a grade: a proof coin is separately graded on a numeric scale, and handling marks or hairlines reduce that grade. Impaired proofs that entered circulation are graded under a different designation.

public-private partnershipsStocks

A public-private partnership is a long-term contract in which a government engages a private consortium to design, build, finance, operate, or maintain public infrastructure, with responsibilities and risks allocated by the agreement rather than by ownership alone. Payment comes either from users, as in a toll road concession, or from the public authority through availability payments tied to keeping the asset in service to a defined standard. Contracts commonly run for decades and specify performance standards, deductions for failure, handback condition, and the treatment of refinancing gains and early termination.

purchase-price allocationStocks

Purchase price allocation is the accounting step after an acquisition in which the total consideration paid is assigned to the identifiable assets acquired and liabilities assumed at fair value, with any excess recorded as goodwill. Identifiable intangibles such as customer relationships, technology, trade names, and order backlog are separated from goodwill and given useful lives, which sets future amortization expense. Because the allocation decides how much of the price becomes an amortizing charge against reported earnings and how much sits as non-amortizing goodwill subject to impairment testing, it changes post-deal profit even though cash paid is unchanged.

Par BondStocks

A par bond trades at a price equal to its face value, which happens when its coupon rate matches the yield the market requires for that maturity and credit quality. At that point current yield and yield to maturity are the same, and no premium or discount has to amortise over the remaining life. New issues are usually priced at or close to par by setting the coupon to the prevailing market yield on pricing day.

Pari PassuStocks

Pari passu is a contractual term meaning that two or more claims rank equally, so in a distribution each receives the same proportion of what it is owed rather than one being paid ahead of another. Bond indentures and loan agreements use a pari passu clause to promise that the debt will not be subordinated to future borrowings of the same class. In insolvency the principle governs how a class of unsecured creditors shares whatever value remains after secured and priority claims.

PARTNERStocks

A partner is a co-owner of a partnership who shares in its profits and losses under the partnership agreement. A general partner manages the business and carries unlimited personal liability for its obligations, while a limited partner contributes capital, takes liability only up to that commitment, and stays out of day to day management. In private funds this split defines the structure: the fund manager acts as general partner and investors come in as limited partners. Partnership income is generally taxed at the partner level.

PERPETUITYStocks

A perpetuity is a stream of identical cash flows that continues indefinitely with no final repayment of principal. Its present value is the periodic payment divided by the discount rate, a result that converges because distant payments are discounted so heavily they add almost nothing. A growing perpetuity, where payments rise at a constant rate below the discount rate, divides the next payment by the discount rate minus that growth rate, which is the formula behind terminal value in a discounted cash flow model.

Pillar IStocks

Pillar 1 is the part of the Basel capital framework that sets the minimum regulatory capital a bank must hold against credit, market and operational risk, computed under prescribed standardised or internal model approaches. It fixes the numerator, eligible capital sorted into tiers, and the denominator, risk-weighted assets. Pillar 2 then adds supervisory review of risks the formula misses and of a bank's own capital adequacy assessment, and Pillar 3 requires public disclosure so market participants can compare positions.

Portfolio ConstructionStocks

Portfolio construction is the process of turning a set of return, risk and correlation views plus a set of constraints into actual position sizes. It begins with objectives and horizon, sets exposure across asset classes, then selects instruments and decides weights using methods ranging from fixed policy allocations to mean variance optimisation and risk parity. Constraints such as liquidity, tax treatment, mandate limits and transaction costs bind the result, and a rebalancing rule defines when the portfolio is returned to target.

PRE-REFUNDINGStocks

Pre-refunding is a municipal financing technique in which an issuer sells new bonds before its existing callable bonds can be redeemed and places the proceeds in an escrow of government securities. The escrow is structured to pay the old bonds' coupons until the call date and the call price on that date, so the original issue is defeased and effectively backed by Treasuries rather than by the issuer. The escrowed bonds usually trade with a higher rating and a shorter effective maturity as a result.

Preferred RiskStocksCrypto

A preferred risk is an applicant an insurer classifies as having a lower expected loss than the standard population, and who therefore qualifies for a lower rate. In life underwriting the classification rests on measurable factors such as medical history, laboratory results, build, tobacco use and family history; in property and casualty lines it rests on claims history, construction and exposure characteristics. The classification determines the rate charged and is set by the insurer's own underwriting rules within the limits regulators allow.

Putable Common StockOptionsStocks

Putable common stock is equity issued with an attached right allowing the holder to sell the shares back to the company at a set price on stated dates. The put makes the security part equity and part written option for the issuer, which is why accounting rules generally keep it out of permanent equity and classify it as a liability or as temporary equity. Issuers have used the structure to reassure buyers in offerings where the market doubts the valuation, at the cost of a contingent cash obligation.

primitive securityStocks

A primitive security is an instrument whose payments come directly from the issuer and are not defined by reference to another asset's price. Ordinary shares, plain bonds and bank deposits are examples: the holder receives dividends, coupons or interest from the entity that issued the claim. The category exists to contrast with derivative securities, whose payoffs are contractual functions of some other price or rate, and the distinction matters because valuation of a primitive claim starts from the issuer's own cash flows and credit.

Paid-In CapitalStocks

Paid-in capital is the total amount shareholders have contributed to a company in exchange for shares, recorded in equity and split between the par or stated value of the stock and additional paid-in capital, the excess above par. It measures money raised from investors directly, unlike retained earnings, which accumulate from profits. Secondary market trading between investors does not change it, because no new money reaches the company in those transactions.

Paid-Up CapitalStocksCrypto

Paid-up capital is the portion of a company's issued share capital for which shareholders have actually delivered payment, as opposed to shares issued but only partly paid. In jurisdictions that allow partial calls, the balance is called-up but unpaid capital and directors can call for it later. The figure appears within equity on the balance sheet and is used in company law and regulatory tests, for example minimum capital requirements for licensed entities.

Perpetual BondStocks

A perpetual bond has no maturity date, so the issuer pays coupons indefinitely and never repays principal unless it exercises an embedded call. Its value is the coupon divided by the required yield, which means the price is highly sensitive to rate changes because the cash flows extend without end. Banks issue perpetual instruments to satisfy regulatory capital rules, often with discretionary coupons and loss absorption features, and those clauses make them behave more like equity than senior debt.

Portfolio InvestmentStocks

Portfolio investment is the purchase of financial assets such as shares, bonds and funds for the return they generate, without acquiring control or an active management role in the issuer. In balance of payments statistics it is distinguished from foreign direct investment by the size of the equity stake and the intent behind it, with a threshold of around ten per cent of voting power commonly used to separate the two. Portfolio flows are typically more mobile and reverse faster.

Pretax EarningsStocks

Pretax earnings, also called earnings before tax, are a company's profits after all operating expenses, interest and non-operating items have been deducted but before income tax is applied. The figure lets analysts compare profitability across companies whose effective tax rates differ because of jurisdiction, incentives or one-off tax items. Subtracting the tax provision gives net income, and the relationship between the two implies the company's effective tax rate for the period.

Pretax Profit MarginStocks

Pretax profit margin expresses earnings before tax as a percentage of revenue, computed by dividing pretax income by total revenue and multiplying by one hundred. It captures how much of each unit of sales survives operating costs, interest and non-operating items, while removing distortions caused by differing tax rates. Comparing it with operating margin isolates the effect of financing costs, and tracking it over time shows whether cost or interest pressure is compressing profitability.

Price-to-Cash Flow RatioStocks

The price to cash flow ratio divides a company's share price by its operating cash flow per share, or equivalently market capitalisation by total operating cash flow. Because cash flow adds back non-cash charges such as depreciation and is less exposed to accounting choices than net income, the ratio is used where earnings are distorted by heavy depreciation or write-downs. It ignores capital expenditure, so a variation based on free cash flow is often examined alongside it.

Private-label securitiesStocks

Private-label securities are mortgage-backed or asset-backed bonds issued by banks, broker-dealers or specialist finance companies rather than by a government agency or government-sponsored enterprise, so they carry no agency guarantee. Credit risk sits with investors and is managed by structuring the deal into tranches with a defined loss priority, plus features such as overcollateralisation and excess spread. They typically pool loans that fall outside agency eligibility, including jumbo and non-qualifying mortgages.

Pac-Man defenseStocksCrypto

The Pac-Man defense is a takeover response in which the target turns around and bids for the hostile acquirer. The point is to force the aggressor to spend its cash and attention defending itself, and in some structures to create cross-holdings that neutralise voting power. It demands enormous financial capacity and a willing set of lenders, so it is rare, and it can leave both companies weakened by the debt raised. Regulators, exchange rules and cross-holding provisions in company law constrain how far it can go, and boards more often reach for less destructive responses such as a white knight or a rights plan.

partial recourse loanStocks

A partial recourse loan gives the lender a claim beyond the collateral, but only up to a limit set in the documents. That cap may be a fixed amount, a percentage of the original principal, a burn-down that shrinks as the loan amortizes or as performance targets are met, or a guarantee covering only defined circumstances. The structure sits between full recourse, where the borrower's whole balance sheet stands behind the debt, and non-recourse, where the collateral is the sole remedy, and it lets the parties price a specific slice of downside rather than all or none of it. Project and real estate financings use it extensively.

participation certificateStocks

A participation certificate represents a proportional interest in a pool of loans or in a single loan, entitling the holder to a share of the interest and principal collected as it is received. Mortgage pass-through securities are the best known form, in which the certificate holder receives a pro rata slice of the payments from an underlying pool net of servicing and guarantee fees, so prepayments flow straight through and shorten the investment. Loan participations work similarly in commercial lending, where the lead bank keeps the borrower relationship and sells shares in the credit to other institutions that have no direct claim on the borrower.

paying agentStocks

A paying agent is the institution an issuer appoints to distribute interest and principal on a security to its holders. It receives funds from the issuer on each payment date and passes them through the clearing systems or registrar to the entitled accounts, handles any withholding tax obligations, and cancels matured instruments. The role is administrative rather than credit-bearing: the agent pays only what the issuer has funded and gives no guarantee of its own, so a missed payment is the issuer's default rather than the agent's. On international issues the same institution often acts as fiscal agent, taking on additional documentary duties short of the fiduciary responsibilities a trustee assumes.

payoffOptionsStocks

A payoff is the amount a contract delivers at settlement as a function of the underlying's value, stated before any premium already paid is taken into account. A long call has a payoff equal to the greater of zero and the underlying price minus the strike; a forward has a payoff equal to the underlying price minus the contracted price, positive or negative. Subtracting the premium converts the payoff into a profit and loss profile, which is why the two diagrams look alike but sit at different heights. Payoff diagrams are the standard tool for combining legs of a strategy, since positions add vertically at each price.

PO(principal-only strip) Stocks

A principal-only strip is the piece of a mortgage-backed security that receives only the principal portion of the underlying loan payments, with the interest portion going to a separate interest-only strip. It is bought at a deep discount to face value and returns par over time, so anything that accelerates principal repayment raises the return by pulling those cash flows forward. Falling interest rates encourage refinancing, which speeds prepayment, so the strip typically gains value as rates fall and loses as they rise, giving it long duration. It is often paired with an interest-only strip, whose price moves the opposite way.

portfolio pumpingStocksCrypto

Portfolio pumping is the practice of buying additional shares of positions a fund already holds, in the closing minutes of a reporting period, to lift their marked prices and flatter the reported return. It works on thinly traded names where a modest order moves the close, and the effect typically reverses in the following session. Because reported performance drives fees, flows and rankings, securities regulators treat it as marking the close, a form of market manipulation, and have brought enforcement actions against advisers for it. Academic studies detect it through abnormal quarter-end returns in small-cap holdings followed by first-day reversals.

positive convexityStocks

Positive convexity means a bond's price rises more when yields fall than it falls when yields rise by the same amount. Duration alone predicts a straight-line response, so convexity is the curvature correction: for an option-free bond the price and yield relationship bows toward the origin, which works in the holder's favour in both directions. The effect grows with maturity and with lower coupons, and it makes such bonds more valuable when yield volatility is high. Callable bonds and mortgage-backed securities can display negative convexity instead, because the issuer's or borrower's option truncates price gains as yields fall.

positive working capitalStocks

Positive working capital exists when current assets exceed current liabilities, so the resources expected to become cash within a year are larger than the obligations due in the same period. It provides a cushion for paying suppliers and payroll without emergency borrowing, and lenders often require a minimum level as a covenant. A large surplus is not automatically good: it can mean cash sitting idle, inventory that is not selling, or receivables that are being collected slowly, all of which tie up capital that could earn a return elsewhere. Interpretation therefore depends on the composition of the current accounts rather than the total alone.

prepayment modelStocks

A prepayment model forecasts how quickly borrowers in a mortgage pool will repay principal ahead of schedule, which determines the timing of cash flows and therefore the value of the securities backed by that pool. The main driver is the refinancing incentive, the gap between the borrowers' existing rate and available market rates, adjusted for burnout, meaning that borrowers who did not refinance during an earlier opportunity are less likely to respond to the next one. Models also allow for housing turnover, seasoning, loan size, credit quality, seasonality and transaction costs. Output is usually expressed as a conditional prepayment rate or as a multiple of a standard benchmark.

prepetition phaseStocks

The prepetition phase is the period before a debtor files a bankruptcy petition, and the label matters because United States bankruptcy law treats claims and transactions differently depending on which side of the filing they fall. Obligations incurred before the filing become prepetition claims, subject to the automatic stay and paid only through the plan according to priority, while obligations incurred afterward are administrative expenses paid ahead of them. Transfers made during defined look-back windows before the filing can be recovered as preferences or fraudulent transfers. Distressed investors analyse this period closely, since it sets the claim structure the eventual restructuring must resolve.

price keeping operations(PKO) StocksCrypto

Price keeping operations refers to intervention intended to support share prices, most closely associated with Japan in the 1990s when public pension and postal savings money was directed into the equity market during periods of sharp decline. The mechanism is straightforward buying pressure applied by an entity that is not seeking a market return, often timed around fiscal year-end when banks needed unrealized equity gains to support reported capital. Critics argue such support delays price discovery, weakens the incentive to restructure and transfers risk to public balance sheets. The phrase is descriptive market language rather than an official policy label.

price takerStocksCrypto

A price taker is a participant whose own trading or output decisions are too small to move the market price, so it accepts the prevailing price as given. In economics the term describes firms in perfect competition, which face a horizontal demand curve and can sell any quantity at the market price but nothing above it. In trading it describes an investor whose order size sits well within available depth. The opposite is a price maker or price setter, which has enough market share, product differentiation or order size that its decisions change the price others face.

principalStocks

Principal has three distinct meanings in finance, separated by context. In lending it is the amount borrowed and still owed, on which interest is calculated and which amortization repays over time. In trading it describes a firm dealing for its own account and balance sheet, taking the other side of a customer order rather than acting as agent for a commission. In agency law it is the party on whose behalf an agent acts and who is bound by the agent's authorised actions. The trading and agency senses both turn on the same underlying question of who bears the economic consequences of a transaction.

prior lien bondStocks

A prior lien bond ranks ahead of other secured bonds of the same issuer over the same collateral, so its holders are repaid first from that property in an enforcement. Such issues typically arose from reorganizations, particularly of railroads and utilities, where new money had to be raised and could only be attracted by placing it in front of existing mortgage bonds, usually with the consent of those holders. The lien position, rather than the coupon, is the defining feature, and later issues secured on the same assets become junior or general lien bonds ranking behind it.

private bankerStocks

A private banker manages the banking, credit and investment relationship for wealthy individuals and families, typically above a stated asset threshold set by the institution. The service combines deposit and lending arrangements, such as securities-backed borrowing and property finance, with portfolio management, custody and referrals into trust, estate and tax planning specialists. Compensation reaches the bank through fees on assets, lending spreads and transaction charges. The role differs from a retail relationship manager in the size and complexity of balance sheets handled, and from an independent adviser in that the banker sits inside an institution whose own products form part of the offering.

pro-forma income statementOptionsStocks

A pro-forma income statement presents results on an adjusted or hypothetical basis rather than strictly as accounting standards require. Two uses dominate. Transaction pro-formas restate historical results as if an acquisition, disposal or refinancing had occurred at the start of the period, so the combined business can be compared with prior years, and securities regulators prescribe how these are prepared and presented. Management pro-formas exclude items the company considers non-recurring, such as restructuring charges or share-based compensation. The second kind is not standardized, so the adjustments must be reconciled to the reported figures and read with attention to which costs keep recurring in every period.

profit takingStocks

Profit taking is selling a position that has appreciated in order to convert an unrealized gain into cash. Commentators use the phrase to explain a decline that follows a strong run, on the reasoning that holders with gains are choosing to realize them rather than that new negative information has arrived, although the explanation is applied after the fact and is difficult to verify. In taxable accounts the decision has consequences beyond the price, since realizing a gain triggers a tax event whose treatment depends on the holding period and the jurisdiction, which is one reason realized and unrealized positions are managed differently.

protected cell companyStocks

A protected cell company is a single legal entity divided by statute into separate cells, each with its own assets and liabilities that are legally ring-fenced from every other cell and from the company's general account. Creditors of one cell have no claim on the assets of another, so unrelated programmes can share one corporate shell, one board and one set of licences without pooling risk. Captive insurance, insurance-linked securities and some fund platforms use the structure because it removes the cost of forming and capitalizing a separate company for each participant. Effectiveness depends on the segregation being recognised by the courts of any jurisdiction where a claim is brought.

protection buyerStocks

The protection buyer is the party in a credit default swap that pays a periodic premium in exchange for compensation if the reference entity suffers a defined credit event such as bankruptcy, failure to pay or, where applicable, restructuring. Economically the position is short credit risk and behaves like being short the reference entity's bonds, gaining value as spreads widen. Buyers include lenders hedging an actual exposure and investors expressing a negative view without owning the underlying debt, which is the naked case. Settlement after a credit event follows an auction that sets the recovery price, and the buyer receives par less that recovery.

protection sellerStocks

The protection seller is the party in a credit default swap that receives a periodic premium and agrees to compensate the buyer if the reference entity suffers a defined credit event. The position is economically long credit risk, similar to owning the reference entity's bonds funded at the benchmark rate, and it gains as spreads tighten and loses as they widen. Sellers include insurers and funds seeking credit exposure without buying bonds, and dealers hedging offsetting trades. The maximum loss is the notional less the recovery determined at auction, which is why the position is collateralized daily and why concentrated selling can accumulate exposure far larger than the premium received suggests.

public financeStocks

Public finance studies how governments raise and spend money and the economic effects of doing so. Its subjects are taxation and who ultimately bears each tax, expenditure on public goods, transfers and social insurance, budget deficits and the accumulation of public debt, and the division of responsibilities between national and subnational governments. For investors the field is practical rather than abstract: it governs the credit analysis of sovereign and municipal bonds, since the capacity to service debt depends on the tax base, the flexibility of spending and the legal priority given to debt service. The term is also used in markets to mean the business of underwriting municipal securities.

pull to par(pull to maturity) Stocks

Pull to par is the tendency of a bond's price to converge on its face value as maturity approaches, regardless of where it traded earlier in its life. The reason is contractual: the issuer repays a fixed amount on a fixed date, so the remaining cash flows shrink and any discount or premium must be amortized away by that point. A bond bought below face value therefore earns part of its yield from price appreciation and one bought above earns less than its coupon suggests. Duration falls alongside it, which is why an aging bond becomes progressively less sensitive to interest rate moves.

pure arbitrageStocksOptions

Pure arbitrage exploits an actual price discrepancy in identical or contractually equivalent assets to lock a riskless profit with no net capital committed. The classic cases are buying a security on one venue while selling it on another at a higher price, and constructing a synthetic position from options that violates put-call parity against the underlying. It differs from risk arbitrage and statistical arbitrage, which take real exposure to an event or to a historical relationship and are not riskless despite the name. Opportunities are brief and small because the trade itself removes the discrepancy, so capturing them depends on execution speed and low transaction costs.

pure catastrophe swapStocks

A pure catastrophe swap transfers natural catastrophe risk between two parties through a bilateral contract rather than through a bond or a traditional reinsurance policy. One side pays a periodic fee and receives a payment if a defined event occurs, with the trigger set on indemnity losses, an industry loss index, or physical parameters such as recorded wind speed or earthquake magnitude at specified locations. Parametric triggers settle quickly because no loss adjustment is needed, at the cost of basis risk when the payout does not match the buyer's actual damage. Insurers also use the structure to swap exposure to different perils and regions with each other, diversifying without moving premium.

pure playStocks

A pure play is a company whose revenue comes overwhelmingly from a single business line, so its results track that activity directly rather than being blended with unrelated segments. Investors seek them when they want targeted exposure to a theme, and analysts use them as comparables when valuing a division inside a diversified group, since a conglomerate offers no clean market price for any one segment. The concentration cuts both ways: without offsetting businesses, a downturn in the single end market flows straight through to earnings. Spin-offs are often justified on the argument that the separated business will be valued more clearly as a pure play.

put on a putOptionsStocks

A put on a put is a compound option: the holder buys the right to sell an underlying put option at a set strike on a set date. Two strikes and two expiries are involved, one pair for the compound contract and one for the option it delivers. The structure is used when a hedge may or may not be needed, for example by a bidder that will require downside protection only if its tender succeeds, since paying a small premium now preserves the choice without buying the full hedge. Total cost is lower than buying the underlying option outright, but higher if the second option is eventually acquired.

put priceStocks

The put price is the amount an issuer must pay a bondholder who exercises a put option written into the indenture, requiring the issuer to buy the bond back on a specified date. It is usually par, sometimes with accrued interest, and the dates on which the right can be exercised are set out in a put schedule. The feature protects the holder against rising yields and against credit deterioration, so a putable bond carries a lower coupon than an otherwise identical bond without one. Analysts price such issues on yield to put when the option is likely to be used, and treat the put date as the effective maturity.

par yieldStocks

The par yield for a given maturity is the coupon rate at which a newly issued bond of that maturity would price exactly at face value. Because the bond has no discount or premium to amortize, its coupon equals its yield to maturity, which makes the par rate a clean benchmark for comparing borrowing costs across maturities. It is derived from the underlying zero coupon or spot rates by finding the coupon that makes the present value of all payments equal one hundred, so the par, spot and forward curves are three views of the same information. Swap rates are quoted on the same basis.

Putable Asset SwapStocksOptions

An asset swap package in which the investor holds the right to terminate the swap at a preset price if the underlying bond defaults or another agreed trigger occurs. A plain asset swap leaves a buyer who loses the bond still obligated on the swap. Adding the put removes that residual exposure, so the package behaves closer to a synthetic floating rate note. The embedded option is paid for through a lower spread over the floating benchmark.

Pledged AssetStocks

An asset a borrower assigns as security for a loan while keeping ownership of it. The lender records a lien and can seize and sell the asset on default, which lowers its expected loss and usually the interest rate charged. Securities, deposits, receivables, equipment and property are common. Some mortgage programs let a borrower pledge an investment account instead of making a larger cash down payment, leaving the account invested but encumbered.

Pooled FundsStocks

Money contributed by many investors and managed as a single portfolio, with each participant owning units representing a proportional claim on the whole. Combining capital buys diversification and institutional pricing that a small account could not reach alone, and costs are shared across the pool. Mutual funds, collective investment trusts inside retirement plans, and pension pools all use the structure. Returns and losses accrue to unit holders in proportion to their holdings.

PEGGINGStocksFutures

Holding a currency at or near a fixed rate against another currency or a basket, maintained by a central bank that stands ready to buy or sell reserves at the chosen level and often supports it with interest rate policy and capital controls. A peg imports the anchor country's monetary conditions and can break when reserves run short against sustained selling. The word also describes manipulative trading intended to hold a price at a level, for example near an option strike into expiration.

Portfolio ReturnStocks

The gain or loss on a collection of holdings over a period, expressed as a percentage of the value invested. It equals the weighted average of the individual asset returns, each weight being that asset's share of portfolio value at the start of the period, plus the effect of any rebalancing. Time-weighted calculations strip out the timing of cash flowing in and out so a manager can be compared with a benchmark, while money-weighted calculations keep it because it drives what the owner actually earned.

Principal-Only (PO) Strip(PO strip) Stocks

The class of a stripped mortgage-backed security that receives only the principal payments from the underlying loan pool and no interest, so it is bought at a deep discount to face value. Faster prepayment returns that face amount sooner and raises the return, which makes the strip gain value when rates fall and borrowers refinance. That gives it unusually long duration and makes it a mirror image of the interest-only strip, whose cash flows shrink as the loans pay down.

Prepayment RiskStocks

The risk that borrowers repay mortgage or other amortizing loans earlier than scheduled, returning principal to the investor at a time when it can only be reinvested at lower rates. Refinancing waves triggered by falling rates are the main driver, alongside home sales and defaults made whole by a guarantor. It shortens the security's average life exactly when longer duration would have been valuable, capping price gains in a rally, an effect known as negative convexity.

Private Equity Real EstateStocks

Property investment made through closed-end commingled funds or separate accounts rather than through listed shares. Managers raise commitments from institutions, call capital as assets are bought, add value through development, leasing or repositioning, and return proceeds on sale over a fund life measured in years. Strategies run from core, holding stabilized income-producing buildings with modest leverage, to opportunistic, using high leverage and development risk. Interests are illiquid and valuations rest on periodic appraisal.

Product PortfolioStocksCrypto

The full set of products or business lines a company sells, analyzed together for how each contributes cash, growth and risk. Frameworks such as the growth-share matrix classify lines by market growth and relative share to decide where to invest, where to harvest cash and where to exit. Viewing them as a portfolio matters because mature cash-generating lines can fund lines that consume cash while they scale, and because concentration in one line raises the cost of a single market turning down.

Profitability RatiosStocks

Measures that express profit relative to the sales, assets or equity that produced it, so companies of different sizes can be compared. Margin ratios divide gross, operating or net profit by revenue and show how much of each dollar of sales survives each layer of cost. Return ratios such as return on assets, return on equity and return on invested capital divide profit by the capital employed and show how efficiently that capital works. Interpretation requires comparison within the same industry, because typical levels differ widely.

Payment in Kind (PIK) SecurityStocks

A bond or preferred instrument that pays its coupon by issuing additional securities or increasing the principal balance instead of paying cash. It preserves cash at the issuer during heavy investment or after a leveraged buyout, at the cost of a compounding balance that must eventually be refinanced or repaid. Investors demand a higher rate for the deferral and treat the exposure as high risk, since a company using the feature is usually already tight on cash.

Prime BrokerageStocks

A bundle of services investment banks provide to hedge funds and other leveraged investors, centered on financing positions, lending securities for short sales, and holding assets in custody. It also covers consolidated reporting across executing brokers, margin and collateral management, trade clearing, and introductions to potential investors. The bank earns financing spreads, stock loan fees and commissions, and takes counterparty exposure it controls through margin terms and by rehypothecating client collateral within agreed limits.

Paper TradeStocksCrypto

A simulated transaction recorded but not actually executed, used to test a strategy or learn a platform without committing money. Brokers provide simulators that price fills against live market data. Results systematically overstate what live trading would produce, because a simulator usually fills at the quoted price without competing for the same liquidity, ignores the market impact of the order, and removes the emotional pressure of real losses that changes how orders are actually placed.

Payment-in-KindStocks

Settling an obligation by delivering goods, services or additional securities instead of cash. In debt markets it means an issuer meeting a coupon by adding to the principal balance or issuing more notes, which preserves cash but compounds the amount eventually owed. The term also covers dividends paid in extra shares and, in agriculture, government programs that compensated farmers with commodities from public stocks rather than money.

Personal FinanceStocks

The management of an individual's or household's money, covering budgeting, saving, borrowing, insurance, investing, tax planning and provision for retirement and estate transfer. Decisions in each area interact: how much debt is carried affects how much can be saved, and the account type an investment sits in affects what the return is worth after tax. The field is concerned with matching cash flows and risk to a household's own goals and time horizon rather than with maximizing return alone. Full guide →

Portfolio ManagerStocks

The person responsible for deciding what a fund or account holds, working within the mandate's rules on eligible assets, concentration, risk and benchmark. The role covers security selection or allocation, sizing positions, managing cash flowing in and out, and controlling risk against the benchmark, with performance measured as return relative to that benchmark and to peers. Managers of registered funds owe fiduciary duties to holders and operate under compliance rules covering personal trading and allocation of orders across accounts.

passive managementStocksCrypto

Passive management holds a portfolio designed to track a published index rather than to select securities expected to outperform. The manager replicates the index weights, or samples them, and trades mainly to reflect index changes and cash flows, which keeps turnover, research cost and fees low. Performance is judged by tracking difference and tracking error against the benchmark rather than by return above it, since matching the index is the stated objective.

passive market-index portfolioStocksCrypto

A passive market-index portfolio holds every security in a broad market index in the same proportions the index uses, so its return before costs equals the index return. It serves as the practical stand-in for the theoretical market portfolio in the capital asset pricing model and as the benchmark against which active strategies are measured. Because weights adjust automatically with prices, a capitalization-weighted version trades only for index additions, deletions and corporate actions.

primary dealersStocksCrypto

Primary dealers are banks and broker-dealers approved to trade directly with a central bank and to bid in government debt auctions. In return for that access they are expected to bid meaningfully at every auction, make continuous two-way markets in government securities, and report position and flow data to the authorities. The network gives the treasury reliable distribution for new issuance and gives the central bank counterparties for open market operations.

protective covenantStocks

A protective covenant is a clause in a loan agreement or bond indenture that constrains the borrower in order to defend the lender's claim. Negative covenants forbid actions such as pledging assets to another lender, paying large dividends or taking on debt above a stated leverage ratio. Affirmative covenants require reporting, insurance and maintenance of financial tests. Breaching one is an event of default, which can accelerate repayment even if no payment was missed.

pure yield pickup swapStocks

A pure yield pickup swap sells one bond and buys another of longer maturity or lower credit quality purely to collect a higher yield, with no forecast about interest rates or spreads involved. The investor accepts more duration or more credit risk in exchange for the extra income, and the trade is intended to be held rather than reversed. A rise in market yields or a deterioration in the new issuer's credit can outweigh the yield gained.

Pension PlanStocks

An employer-sponsored arrangement that sets money aside during working years to provide income in retirement. In the defined benefit form the employer promises a formula-based payment, usually built from years of service and final or average pay, and carries the investment and longevity risk in a funded trust. In the defined contribution form the employer and employee pay into an individual account and the retirement income depends on contributions and investment results. Funding standards, vesting rules and any insurance backstop are set by legislation in each jurisdiction.

Personal IncomeStocks

The total income households receive from all sources before personal taxes: wages and salaries, employer contributions to benefit plans, proprietors' income, rental income, interest and dividends, and government transfer payments such as social security and unemployment benefits. In the United States the Bureau of Economic Analysis publishes it monthly alongside personal outlays and the saving rate, and it is one of the indicators used to date business cycles. Subtracting personal current taxes gives disposable personal income, the amount available to spend or save.

Policy-ineffectivenessOptionsStocks

A proposition from rational expectations macroeconomics, associated with Thomas Sargent and Neil Wallace, arguing that systematic and therefore anticipated monetary policy cannot change real output or employment. If people form expectations using all available information and understand the policy rule, they adjust wages and prices immediately when a predictable change arrives, leaving only the price level altered. Only the unanticipated component of policy has a real effect. Objections rest on nominal rigidities such as staggered contracts and menu costs, which give even foreseen policy traction for a time.

Portfolio VarianceStocksCrypto

A measure of how much a portfolio's return fluctuates, computed from the weight and variance of each holding plus the covariance between every pair. The pairwise terms are what make diversification work: when assets do not move together, the combined figure comes out below the weighted average of the individual variances, and combining assets with low or negative correlation lowers it further. Its square root is the portfolio standard deviation, the form usually quoted as volatility. The calculation relies on estimated covariances, which shift over time and tend to rise in crises.

Premium BondStocks

A bond trading above its face value, which happens when its coupon exceeds the yield the market currently demands for that credit and maturity. The buyer pays more than will be repaid at maturity, so the extra amount is amortized away over the remaining life and the yield to maturity comes out below the coupon rate. Such bonds carry less price sensitivity to a given yield change than an equivalent discount bond, and they are more exposed to early redemption, since a high coupon gives the issuer a reason to call. In the United Kingdom the same phrase names a government savings product whose return is delivered by prize draw.

Property ManagementStocks

The operation of real estate on an owner's behalf: marketing vacant space, screening tenants, signing and enforcing leases, collecting rent, arranging maintenance and repairs, paying operating bills, keeping the accounts and handling compliance with local housing and safety rules. Managers are usually paid a percentage of collected rent plus leasing commissions and fees for capital projects. For an investor the cost reduces net operating income and therefore the value a capitalization rate produces, so it is included as an expense even when the owner does the work personally.

Paris Club meetingStocks

A Paris Club meeting is a negotiation in which official bilateral creditors, the governments and export credit agencies making up that informal group, agree common terms for rescheduling or reducing debt owed to them by a country that cannot pay. The group works case by case, normally requires the debtor to have an International Monetary Fund program in place, and applies comparability of treatment, which obliges the debtor to seek similar terms from creditors outside the group.

passing the bookStocksFutures

Passing the book is the handover of a trading position from a dealer's desk in one time zone to the same firm's desk in the next as the local session closes, so the risk stays actively managed around the clock. The receiving desk inherits the position, the limits and any resting orders, and reports back at the next handover. It is standard practice in foreign exchange and global rates, and the handover record is a control point that supervisors examine.

path-independent optionOptionsStocks

A path-independent option has a payoff determined solely by the price of the underlying at expiration, no matter what route the price took to get there. Standard European calls and puts are the base case, since only the final settlement level enters the payoff formula, which is what makes them tractable with closed-form valuation methods. Path-dependent contracts such as barriers, lookbacks and Asian options are the contrast: a level touched or an average taken along the way changes what is owed.

pension mortgageStocks

A pension mortgage is an interest-only home loan arranged alongside a personal pension, where the borrower pays interest to the lender and separately contributes to the pension, intending to repay the capital from the cash lump sum the pension can pay at retirement. It was marketed mainly in the United Kingdom. Repayment depends on investment performance and on the proportion of a pension that rules allow to be taken as cash, which HM Revenue and Customs sets and revises.

performance benchmarkingStocks

Performance benchmarking measures a portfolio against a reference series chosen to represent the opportunity set the manager was hired to work in. The comparison produces active return, the difference between the two, and tracking error, the volatility of that difference. A benchmark is only informative if it is investable, published in advance, and matched to the mandate's currency, sector and size profile, because a mismatched reference makes a manager look skillful or poor for reasons unrelated to any decision taken.

phantom stockStocks

Phantom stock is a contractual promise to pay an employee an amount tied to the value of a company's shares, without issuing any actual shares. Units are credited at grant, track the share price and sometimes accrue dividend equivalents, then settle in cash on vesting or at a defined event such as a sale. Because no equity changes hands, existing owners are not diluted. Payments are generally treated as compensation under rules set by the relevant tax authority.

Pillar III(Pillar 3) Stocks

Pillar III is the disclosure component of the Basel capital framework, alongside Pillar I's minimum capital calculations and Pillar II's supervisory review. It requires banks to publish standardized information about capital resources, risk-weighted assets, leverage, liquidity, and the methods used to measure credit, market and operational risk. The intent is market discipline: if counterparties, depositors and investors can compare risk profiles on a consistent basis, funding costs respond before a supervisor has to intervene.

placementStocksCrypto

A placement is the distribution of a block of securities to investors by an intermediary that builds a book of demand and then allocates at an agreed price. It can be primary, raising new money for the issuer, or secondary, moving an existing holder's stake without changing the share count. Placements run privately to selected institutions under an exemption, or publicly with full disclosure, and an accelerated bookbuild compresses the process into a few hours after the market closes. Allocation is discretionary rather than pro-rata.

poolingStocks

Pooling combines many individual assets, usually loans or receivables, into a single portfolio whose combined cash flows are then treated as one source of payment. It is the first step in securitization: a sponsor transfers the pool to a separate vehicle, which issues securities backed by it. The economic point is diversification, since idiosyncratic defaults across a large pool are more predictable in aggregate than in any single loan, although losses that hit the whole pool together remain undiversified.

poop and scoopStocksCrypto

Poop and scoop is a manipulation in which someone spreads false or misleading negative information about a company to drive its share price down, then buys the shares cheaply before the claim is disproved and the price recovers. It is the mirror image of a pump and dump. Securities regulators treat it as fraud under general anti-manipulation provisions, and it typically leaves an evidence trail in the perpetrator's own trading records alongside the posts or messages that spread the claim.

positive basisStocks

A positive basis exists when the credit default swap spread on an issuer exceeds the credit spread available on that issuer's cash bond. Basis equals the swap spread minus the bond spread. It often appears when protection buyers outnumber sellers, when the cash bond is expensive because it is scarce or locked up by buy-and-hold investors, or when the obligations deliverable under the swap are broader than the bond alone, which makes the contract worth more than the bond's own spread.

positive gapStocks

A positive gap arises when a bank's rate-sensitive assets repricing within a chosen time band exceed its rate-sensitive liabilities in that band. Gap equals rate-sensitive assets minus rate-sensitive liabilities, so a positive figure means more of the balance sheet reprices upward when rates rise, widening net interest income, and downward when rates fall. Gap analysis is a coarse screen: it ignores the size of rate moves, embedded options such as prepayment, and the timing of cash flows inside each band.

positive yield curveStocks

A positive yield curve slopes upward, so longer-dated bonds of the same credit quality yield more than shorter-dated ones. Explanations include a term premium demanded for tying money up and bearing greater price sensitivity to rate changes, and expectations of higher future short rates. It is the shape observed most of the time, which is why it is also called a normal curve, and its steepness is measured by the spread between two chosen maturity points.

preannouncementStocks

A preannouncement is a company's release of key results, usually revenue or earnings, ahead of its scheduled reporting date. Firms issue one when actual figures will differ enough from published expectations that waiting would leave the market misinformed, and disclosure rules generally require the release to reach all investors at once rather than selected analysts. A preannouncement flagging a shortfall is often called a profit warning; one flagging a beat carries the same disclosure obligations.

premium currencyStocks

A premium currency is one whose forward exchange rate is higher than its spot rate against a given counterpart, meaning it buys more of that counterpart for future delivery than for immediate delivery. The gap is arithmetic rather than a forecast: covered interest parity fixes the forward rate from the spot rate and the interest rate differential, so the currency carrying the lower interest rate trades at a forward premium and the higher-rate currency trades at a forward discount.

premium over bond valueStocks

Premium over bond value measures how much more a convertible bond costs than the straight debt inside it is worth. Investment value is what the bond would be priced at with no conversion right, discounting its coupons and principal at the yield on comparable non-convertible debt of the same issuer. The premium is the market price minus that value, usually shown as a percentage of it, and it quantifies how much of the price is being paid for the embedded equity option.

pro-rataStocksCrypto

Pro-rata means allocating an amount in proportion to each participant's share of a defined total. In an oversubscribed offering, every order receives the same fraction of what it asked for. On exchanges that use pro-rata matching, a resting order at the best price is filled in proportion to its size rather than by time priority, which rewards displaying large size instead of arriving first. Interest, dividends and insurance premiums are also apportioned this way across part of a period.

profitability indexStocks

The profitability index is the present value of a project's future cash flows divided by the initial investment required. A value above one means the discounted inflows exceed the outlay, the same signal as a positive net present value. Its use is in ranking: when capital is rationed and projects differ in size, the index shows value created per unit of money committed, which net present value alone does not, though it can mislead when projects are mutually exclusive.

put protected equityOptionsStocks

Put protected equity is an equity portfolio held together with put options on the same or a correlated index, so that losses below the strike are offset by the options' payoff. The structure converts an open-ended downside into a defined one, at the cost of the premium paid, which is a continuing drag whenever the protection is rolled. How well it works depends on the basis between the holdings and the index used, the strike chosen relative to spot, and the tenor bought.

prisoners' dilemmaOptionsStocks

The prisoners' dilemma is a game in which each participant does better by defecting whatever the other chooses, yet both end up worse off than if they had cooperated. Named for two suspects questioned separately, it shows how individually rational choices produce a collectively poor outcome when no binding commitment is available. Finance uses it to explain runs on a bank, price wars, creditors racing to enforce against a distressed borrower, and the difficulty of sustaining output limits within a cartel.

portable alphaStocksCrypto

Portable alpha is a portfolio design that funds a benchmark exposure synthetically, using futures or swaps that require only margin, and invests the freed capital in a return source unrelated to that benchmark. The portfolio therefore delivers the intended market return plus whatever the separate source earns, less financing cost. Its central dependency is liquidity: the derivative leg needs cash for variation margin, so the return engine has to be redeemable quickly or the position must be cut at the worst moment.

PATH ActStocks

The Protecting Americans from Tax Hikes Act is United States legislation enacted in 2015 that made several temporary tax provisions permanent instead of leaving them to expire and be renewed annually, including the research credit and enhanced expensing for certain business assets. It also tightened refund procedures, requiring the Internal Revenue Service to hold refunds on returns claiming certain family credits until identity and eligibility checks are complete, and it modified the rules governing foreign investment in United States real property and the treatment of REIT spin-offs.

PIIGSStocks

PIIGS is an acronym used in financial commentary during the euro area sovereign debt crisis for Portugal, Italy, Ireland, Greece and Spain, the member states whose government borrowing costs rose sharply from 2010 as investors questioned their debt sustainability. Their common features were large deficits or banking sector losses combined with the inability to devalue or set independent monetary policy inside a currency union. The label is widely regarded as pejorative and has fallen out of use in professional publications.

Paper MoneyStocks

Paper money is currency issued as printed notes that circulate as a medium of exchange. Modern issues are fiat money: they are not redeemable for a commodity and derive value from legal tender status and confidence in the issuing authority, which controls the quantity in circulation. Earlier forms were representative, exchangeable on demand for a stated weight of gold or silver. Because supply can be expanded at negligible cost, the purchasing power of paper money depends on the discipline of the issuer.

Personal Consumption ExpendituresCryptoStocks

Personal consumption expenditures measure the total value of goods and services bought by households, and they form the largest component of gross domestic product in most advanced economies. In the United States the Bureau of Economic Analysis publishes the series along with a price index derived from it, and the core version of that index, which excludes food and energy, is the inflation measure the Federal Reserve uses for its target. Its weights update as spending patterns shift, which distinguishes it from the fixed-basket consumer price index.

Personal PropertyStocks

Personal property is anything a person or business owns that is not land or permanently attached to it. It divides into tangible items such as vehicles, equipment, inventory and household goods, and intangible items such as shares, bonds, bank balances, patents and contractual rights. The distinction from real property matters for how ownership transfers, how a security interest is created and perfected, how the asset is treated in bankruptcy, and whether local property tax applies to it.

Point-and-Figure (P&F) ChartStocks

A point-and-figure chart plots price movement without reference to time, filling a column of X marks while price rises and a column of O marks while it falls. A new mark is added only when price moves by a set box size, and the chart switches columns only when it reverses by a specified multiple of that box, commonly three boxes. Filtering out smaller fluctuations produces a clean picture of support, resistance and breakouts, and column counts are used to derive price objectives.

Portfolio RunoffStocksCrypto

Portfolio runoff is the natural shrinkage of a pool of loans or securities as borrowers repay principal, issues mature and prepayments arrive, with no new assets bought to replace them. Lenders let a book run off when they exit a product line, and central banks use the same mechanism to reduce a balance sheet by allowing holdings to mature without reinvesting the proceeds, a passive alternative to selling into the market. The pace depends on the maturity profile and on how quickly borrowers prepay.

PovertyStocks

Poverty is the condition of lacking the income or resources needed to meet a defined standard of living. Absolute measures compare income against the cost of a basic basket of food, shelter and necessities, while relative measures compare it against the median in the same society, a common threshold being some fraction of that median. Statistical agencies publish poverty lines and update them for prices and household composition, and multidimensional measures add access to education, health and services alongside income.

Preference SharesStocks

Preference shares are equity securities that rank ahead of ordinary shares for dividends and for the return of capital in a winding up, usually paying a fixed rate and usually carrying no vote except in defined circumstances. Cumulative issues carry forward any dividend the company misses and must clear the arrears before ordinary holders are paid. Terms vary widely: shares may be participating, convertible, redeemable or perpetual, and the dividend is discretionary in a way bond interest is not, so they sit between debt and common equity in risk.

Price-to-Rent RatioStocks

The price-to-rent ratio compares the cost of buying a home with the cost of renting a comparable one, calculated as the purchase price divided by the annual rent. A high reading indicates that buyers are paying a lot for each unit of housing services, which is often read as a sign of stretched valuations or of expectations that prices will rise. It is used to compare housing markets across cities and over time, though it ignores taxes, maintenance, financing costs and expected capital growth.

Primary Dealer Credit FacilityStocks

The Primary Dealer Credit Facility was an emergency lending programme run by the Federal Reserve Bank of New York that extended overnight and short-term collateralised loans to primary dealers, the securities firms that trade directly with the Federal Reserve. It was created in March 2008 when dealers were unable to fund inventory in the repo market, and it was reopened in March 2020. Because dealers are not deposit-taking banks, the facility gave them access to central bank liquidity that would otherwise be unavailable.

Primary credit rateStocks

The primary credit rate is the interest rate the Federal Reserve charges financially sound depository institutions that borrow at its discount window, and it is set above the target range for the federal funds rate. Loans are short term, fully collateralised and available without the borrower having to demonstrate an inability to obtain funds elsewhere. Because the rate sits above market alternatives, it acts as a ceiling on short-term interbank rates, and institutions that do not qualify may borrow at the higher secondary credit rate.

Profits InterestOptionsStocks

A profits interest is a stake in a partnership or limited liability company that entitles the holder to a share of future appreciation and earnings but gives no claim on the value that exists on the date it is granted. That threshold, set so the holder would receive nothing on an immediate liquidation, is what distinguishes it from a capital interest. It is used in the United States to compensate managers and key employees of pass-through entities, and its tax treatment depends on meeting requirements set out in Internal Revenue Service guidance.

PropertyStocks

Property is a legally recognised bundle of rights over something of value, chiefly the rights to use it, to exclude others, to take its income and to transfer it. The law divides it into real property, meaning land and whatever is permanently affixed to it, and personal property, meaning everything else, including tangible goods and intangible claims such as shares and patents. How a right is created, recorded, taxed and enforced depends on which category it falls into and on the jurisdiction.

Provision For Credit LossesStocks

The provision for credit losses is the expense a lender records in a period to build or maintain the reserve it holds against loans it expects will not be repaid in full. Under the expected loss standards now used in major accounting regimes, the estimate covers losses anticipated over the life of the exposure and reflects forecasts of economic conditions, rather than waiting for a loss event to occur. Because the charge runs through the income statement, changes in the estimate move reported earnings directly.

Proxy VoteOptionsStocks

A proxy vote is a vote cast at a company meeting by someone the shareholder has authorised to act on their behalf, which is how most shares are voted since few holders attend in person. Companies distribute a proxy statement setting out the resolutions, and holders return voting instructions by mail or electronically, either directing how each item should be voted or leaving discretion to management. Contested situations produce proxy contests, in which a dissident solicits the same votes to change the board or block a transaction.

Pump-and-Dump SchemeStocks

A pump-and-dump scheme is securities fraud in which promoters accumulate a thinly traded asset, spread misleading or exaggerated claims to attract buyers, then sell into the demand they created, leaving later buyers holding a position whose price collapses. It is most common in microcap shares and in low-liquidity digital tokens, where a small amount of buying moves the price sharply. Promotion through social media, messaging groups and paid newsletters is a recurring feature, and the conduct is prohibited under anti-fraud and market manipulation rules.

parentStocks

A parent is a company that controls another company, usually by holding a majority of its voting shares, though control can also arise from contractual arrangements or the ability to appoint the board. The controlled company is a subsidiary. Accounting standards require the parent to prepare consolidated financial statements combining every entity it controls and eliminating transactions between them, so the group is presented as a single economic unit. Each company remains a separate legal person, so a subsidiary's creditors normally have no claim against the parent unless it guaranteed the obligation or a court sets the separation aside.

partial insuranceStocks

Partial insurance is cover that leaves the policyholder bearing some of any loss, through a deductible, a percentage co-insurance share, or a policy limit below the value at risk. The retained portion is deliberate: it gives the insured a continuing financial interest in preventing and mitigating losses, which limits moral hazard, and it removes small claims whose administrative cost would exceed their value. Premium falls as the retained share rises, so the choice trades a certain premium cost against uncertain retained losses. Underinsurance clauses can also impose a partial share where property is insured below its value.

participating dividendOptionsStocks

A participating dividend is the additional payment made to holders of participating preferred shares after they have received their fixed preferential dividend and the ordinary shareholders have received a specified amount. The terms of the issue set the formula, often sharing further distributions in a defined ratio between the two classes. The feature gives preferred holders a claim on upside they would otherwise forgo in exchange for priority, and it is common in venture capital and private company structures. Whether it applies on a sale as well as on dividends depends on the participation terms written into the charter.

participating forwardOptionsStocks

A participating forward is a currency or commodity hedge that fixes a worst-case rate while letting the holder keep a share of any favourable move, arranged so no premium is paid up front. It is built from an option bought at the protection level and a smaller amount of the opposite option sold at the same level, the ratio chosen so the premiums offset. The participation rate is the proportion of a favourable move retained, and it is not free: the protected rate is set worse than the outright forward rate, which is the real price of keeping some upside.

participating optionOptionsStocks

A participating option is a structure in which the buyer pays no premium, or a reduced one, and in exchange gives up part of the benefit when the market moves in their favour. Protection at the strike is complete, while gains beyond it are shared with the seller in a fixed proportion, achieved by combining a purchased option with a partial sale of the opposite one. The label is also used for index-linked products where the holder receives a stated percentage of an index gain with principal protected. In every case the participation rate is what the buyer pays with.

participating preferred stockStocks

Participating preferred stock pays its fixed preferential dividend and also shares in distributions made to common shareholders, instead of being limited to the stated rate. The same feature usually applies on a sale or liquidation: the holder takes the liquidation preference first, recovering the invested amount, and then participates in the remaining proceeds alongside common holders as though the shares had converted. It is common in venture capital terms, where it materially changes how sale proceeds are split, particularly at moderate valuations. Participation is sometimes capped at a multiple of the original investment, after which converting to common becomes the better outcome.

payback periodStocks

The payback period is the time it takes for the cash inflows from an investment to recover the money originally spent on it. With even annual inflows it is the initial outlay divided by the annual inflow; with uneven ones the flows are accumulated until the running total turns positive. It is easy to compute and communicates a rough liquidity and risk screen, which is why it survives alongside better measures. Its two defects are that it ignores the time value of money and that it ignores everything happening after the cut-off, so a project with large later returns can be rejected. Full guide →

pennantStocks

A pennant is a short consolidation on a price chart that follows a steep directional move and takes the shape of a small symmetrical triangle, with converging boundaries formed by lower highs and higher lows. Traders treat it as a continuation pattern, expecting the prior move to resume when price breaks out of the converging range, and often measure a target from the length of the preceding move. It differs from a flag, whose consolidation runs between roughly parallel lines rather than converging. As with all chart patterns, identification is subjective and the outcome is not assured.

performance bondStocks

A performance bond is a guarantee, usually issued by a surety company or a bank, that a contractor will complete a project according to the contract, with the surety liable up to the bond amount if it does not. On default the surety may arrange completion by another contractor, fund the original one, or pay the owner the cost of finishing the work. It is underwritten like credit rather than like insurance, since the surety expects to recover from the contractor and takes an indemnity from it. Public construction contracts commonly require one. The phrase is also used loosely for futures margin.

plus tickStocksCrypto

A plus tick is a trade executed at a price above the price of the immediately preceding trade in the same security, also called an uptick. Together with the zero-plus tick, a trade at the same price as the previous one where the last different price was lower, it defined when short selling was permitted under the United States uptick rule from the 1930s until its removal in 2007. A replacement adopted in 2010 applies a price test only after a security has already fallen by a set percentage from the prior close, rather than continuously.

preemptive rightStocks

A preemptive right entitles existing shareholders to subscribe for new shares before they are offered to anyone else, in proportion to their current holdings, so their percentage ownership and voting power are not diluted without their consent. In the United Kingdom and much of Europe the right is a statutory default that shareholders must vote to disapply, which is why rights issues are the standard route for raising equity there. In most United States states it applies only if the charter provides it, which is one reason placements and public offerings without a rights element are far more common.

preferenceStocks

A preference in insolvency is a payment or transfer a debtor makes to one creditor shortly before failing, which leaves that creditor better off than it would have been in the liquidation. Insolvency law lets a trustee or administrator reverse such transactions within a defined look-back period, so creditors of the same rank share equally. Statutory conditions differ by jurisdiction and typically address the timing, whether the recipient was connected to the debtor, and whether the payment was made in the ordinary course of business. In United Kingdom market usage the word is also shorthand for preference shares.

preferred creditorStocks

A preferred creditor is one whose claim ranks ahead of ordinary unsecured creditors in an insolvency by statute, rather than by contract or by holding security. The categories vary by jurisdiction and commonly include limited amounts of unpaid employee wages and pension contributions and certain taxes collected on the state's behalf. Preferred claims are paid after the costs of the insolvency process and after creditors holding fixed security over specific assets, and ahead of unsecured creditors generally. Because recoveries usually run out well before the unsecured class is reached, ranking is often decisive rather than technical.

premium loadingStocks

Premium loading is the amount added to the expected cost of claims when setting an insurance rate, so the premium covers more than the losses it is expected to pay. It bundles acquisition and administration expenses, premium taxes, a margin for the uncertainty that actual claims exceed the estimate, and a profit allowance. It can also mean a specific surcharge applied to an individual risk that underwriting judges worse than the standard class, such as a driver with a poor record. Either way, the loading is the gap between the pure premium and the price actually charged.

premium raidStocks

A premium raid is an attempt to acquire a large block of a company's shares quickly by offering holders a price well above the market, in order to gain control or a blocking stake before the board or rival bidders can respond. The speed is the point: existing management has little time to organise a defence and other potential bidders little time to compete. Takeover rules in most markets constrain the tactic through disclosure thresholds that force a buyer to announce its stake, mandatory offer requirements once a percentage is crossed, and restrictions on treating shareholders unequally.

price controlStocksCrypto

A price control is a legal limit on what may be charged for a good or service, either a ceiling above which sellers may not price or a floor below which they may not. A binding ceiling set below the market-clearing level produces excess demand and shortages, queues, rationing or informal markets, while a binding floor produces surpluses. Rent regulation and minimum wages are the most debated examples, and both are argued over precisely because the size of the distortion depends on how responsive supply and demand actually are in the market concerned.

price talkStocks

Price talk is the indicative pricing an underwriting syndicate circulates to investors while marketing a new issue, expressed as a yield range, a spread over a benchmark or a discount, to gauge demand before terms are fixed. It is guidance rather than a commitment, and it moves as the order book builds: strong demand lets the syndicate revise the talk to a tighter level, while weak demand widens it or the deal is pulled. Investors read the progression as a live signal of how the issue is being received, and final pricing is set when the book closes.

prior preferred stockStocks

Prior preferred stock ranks ahead of a company's other preferred issues for dividends and for repayment in a liquidation, so its holders must be paid in full before any junior preferred class receives anything. Companies create the class when raising further preferred capital requires offering better priority than existing holders have, and its dividend rate is usually lower to reflect the reduced risk. Both classes still rank behind all debt and ahead of common shares. Whether an issuer can create such a class at all typically depends on protective provisions in the terms of the existing preferred stock.

private bankStocksFutures

A private bank provides banking, credit and investment services to wealthy individuals and families, typically combining discretionary or advisory portfolio management with lending against securities or property, custody, trust and estate structures and cross-border planning. Revenue comes from management fees, a share of transactions and the spread on deposits and loans. The phrase carries a second, older meaning in some markets: a bank owned by partners with unlimited personal liability rather than by shareholders. Suitability, conflict of interest and cross-border marketing rules apply to the advisory activity, and client confidentiality has narrowed under international information exchange agreements.

pro forma earnings reportStocks

A pro forma earnings report presents results on a basis other than the applicable accounting standards, typically excluding items management considers non-recurring or non-cash, such as restructuring charges, acquisition costs, impairments or share-based compensation. Companies argue the adjusted figure shows underlying performance more clearly. The risk is that exclusions are selective and inconsistent between periods, which flatters results. United States rules require any non-standard measure released publicly to be reconciled to the nearest standard measure and prohibit giving it undue prominence, so a reader should compare the adjusted number with the reported one before relying on it.

profitStocks

Profit is what remains from revenue after the costs of earning it. Accounting profit subtracts recorded expenses and is reported at several levels: gross profit after the cost of goods sold, operating profit after selling and administrative costs, and net profit after interest and tax. Economic profit goes further by also subtracting the opportunity cost of the capital and effort employed, so a business can report accounting profit while earning nothing above what its resources could return elsewhere. Profit differs from cash flow, because revenue and expenses are recognised when earned or incurred rather than when money actually moves.

program tradingStocksCrypto

Program trading is the simultaneous execution of a basket of many different stocks as a single coordinated order. The New York Stock Exchange has defined it by thresholds covering the number of stocks in the basket and its total value. Index funds use it to track a benchmark, arbitrageurs to exploit gaps between index futures and the underlying shares, and large investors to move whole portfolios with minimal signalling. Because such orders can hit the market at once, exchanges introduced curbs and later market-wide circuit breakers after the 1987 crash, when concentrated index-related selling was identified as an amplifying factor.

protected bidStocksCrypto

A protected bid is a displayed, automatically executable bid at the best price on a United States exchange, which other trading centres may not trade through. Under the order protection rule of Regulation NMS, a venue must not execute an order at a price inferior to a protected quotation displayed elsewhere, so it either routes the order to that venue or matches the price. Only automated, immediately accessible quotations at the top of an exchange's book qualify: manual quotations and depth behind the best price are not protected. The mirror concept on the sell side is the protected offer.

protected offerStocksCrypto

A protected offer is a displayed, automatically executable offer at the best price on a United States exchange, which other venues may not trade through under Regulation NMS. If a trading centre would otherwise execute a buy order above that price, it must route to the venue displaying it or match it, so the national best offer is respected across a fragmented market. Protection extends only to the top-of-book automated quotation; orders resting deeper in the book and quotations that are not immediately executable can be traded through. The equivalent on the buy side is the protected bid.

pufferyStocksCrypto

Puffery is promotional exaggeration so obviously subjective that no reasonable person would treat it as a statement of fact, such as calling a service the finest available. Because it makes no verifiable claim, it generally does not support an action for misrepresentation, which is why it is distinguished from a specific factual assertion about performance, fees or track record. The distinction is narrower in the marketing of financial products, where advertising rules require communications to be fair, clear and not misleading, and where claims about returns, rankings or comparisons must be substantiated and balanced with risk disclosure.

pure premium rating methodStocks

The pure premium rating method sets an insurance rate by first calculating the pure premium, which is expected losses and loss adjustment expenses divided by the number of exposure units, and then grossing that figure up for expenses and profit. The gross rate is the pure premium divided by one minus the expense and profit ratio. It works directly from loss experience per exposure and needs no existing rate to start from, which is why it suits a new line of business. The alternative loss ratio method instead adjusts an existing rate by comparing actual with expected loss ratios.

purpose loanStocks

A purpose loan is credit extended for the purpose of buying or carrying margin stock, and in the United States it falls under the Federal Reserve's margin rules, which limit how much may be lent against such securities. The lender documents the borrower's stated purpose, traditionally on a specific form, and the limitation applies whatever collateral is pledged. Its counterpart, a non-purpose loan, is secured by securities but used for something else entirely, such as a property purchase or business funding, and is not subject to those margin limits, though the lender still sets advance rates and can issue collateral calls.

packageOptionsStocks

A package in derivatives is a set of positions traded and priced as a single unit, built from standard components such as European calls and puts, forward contracts, cash and the underlying asset. Spreads, collars, range forwards and many structured currency and interest rate hedges are packages assembled to produce a payoff profile the components do not give individually. They are often designed so the premiums of the bought and sold components offset, producing a structure with no upfront cost, which shifts the price into the levels at which protection and participation apply rather than removing it.

Pecking Order HypothesisStocks

The proposition that firms finance investment in a preferred order: internally generated funds first, then debt, and new equity only as a last resort. The logic is asymmetric information. Managers know more about the firm's prospects than outside investors, so an equity issue is read as a signal that the shares are overpriced and the announcement tends to push the price down. It predicts that highly profitable firms borrow less, because they need less outside money.

Pension FundStocks

A pool of assets set aside to pay retirement benefits to a defined group of members, held separately from the sponsoring employer. In a defined benefit arrangement the fund must meet promised payments based on salary and service, so the sponsor bears any shortfall and the assets are measured against a liability. In a defined contribution arrangement the member's benefit depends on contributions and investment results, so the member carries that outcome.

Preferred Habitat TheoryStocksCrypto

A term structure explanation in which investors and borrowers have preferred maturity ranges that suit their own liabilities, and will move outside them only if paid enough to compensate. Yields therefore reflect expected future short rates plus premiums that depend on supply and demand within each maturity segment, and those premiums can be negative where demand for a particular maturity is unusually strong. It sits between pure expectations and strict market segmentation.

Private Mortgage InsuranceStocks

Insurance that protects the mortgage lender, not the borrower, against loss if the borrower defaults and the property sells for less than the outstanding balance. Lenders require it on conventional loans when the down payment is small relative to the purchase price, and the borrower pays the premium monthly, up front, or through a higher note rate. United States federal law lets borrowers request cancellation, and requires automatic termination, once the balance falls to set shares of the original value.

Profit MarginStocks

A ratio expressing a measure of profit as a percentage of revenue, showing how much of each sales dollar survives after a given set of costs. Gross margin deducts the cost of goods sold, operating margin also deducts operating expenses, and net margin deducts everything including interest and tax. Comparing the levels within one company shows where costs bite, and margins are comparable across companies only within the same industry and accounting basis.

Perfect CompetitionStocks

A market structure in which many small buyers and sellers trade an identical product with full information and free entry and exit, so no participant can influence the price. Each firm takes the market price as given and produces where marginal cost equals it, and entry drives economic profit to zero in the long run. It is a benchmark rather than a description of real markets, useful for judging how far actual outcomes depart from it.

P/E effectStocksCrypto

The empirical finding that shares trading on low ratios of price to earnings have historically earned higher average returns than shares on high ratios, documented in United States data from the 1970s onward. Interpretations divide: one treats it as compensation for risk not captured by beta, since low-multiple firms tend to be more leveraged and closer to distress; another treats it as mispricing from investors over-extrapolating growth. It is a precursor of the value factor later built from book to price.

Paired Shares(Stapled Stock) StocksCrypto

Shares of two separate companies that are issued jointly and can be traded only together as a unit, with one certificate or one quoted line representing both. The structure lets two businesses under common control keep separate legal identity and tax treatment while giving investors a single security. It was used in United States real estate to combine a property owner with an operating company before tax legislation restricted new arrangements, and stapled structures elsewhere follow the same principle.

Parallel Money MarketsStocks

The wholesale sterling markets that developed outside the traditional London discount market, in which banks, local authorities, finance houses and companies lend to each other directly without the central bank acting as lender of last resort to the market. Instruments include interbank deposits, local authority loans, certificates of deposit and eurocurrency deposits, and they are unsecured. Their growth changed how policy is transmitted, since short rates are no longer influenced solely through the discount market.

Partial Lookback OptionOptionsStocks

A lookback option in which the extreme price used for settlement is taken over only part of the contract's life, or is adjusted by a percentage factor, rather than over the whole period at the full extreme. Narrowing the observation window or applying a factor reduces the expected payoff and therefore the premium, which is the point: a full lookback is expensive because it settles against the most favourable price ever reached. Valuation still requires modelling the distribution of the running extreme.

Partial Plan TerminationStocks

A situation in which a significant proportion of participants in a qualified retirement plan stop being covered, typically through employer-initiated layoffs or the closure of a division, without the plan being wound up entirely. Where it occurs, the affected participants must become fully vested in their accrued employer-derived benefits regardless of the plan's normal vesting schedule. Whether a reduction is large enough to count is judged on the facts against Internal Revenue Service guidance and case law in the United States.

Partly Paid SharesOptionsStocks

Shares on which only part of the issue price has been paid, leaving the holder liable to pay the balance when the company makes a call. The outstanding amount is a contingent liability that travels with the shares, so a buyer takes on the obligation, and a company in difficulty can call the unpaid capital to raise cash. Large privatisations and rights issues have used instalment structures of this kind to spread payment, and the shares trade at a price reflecting the outstanding call.

Passive Loss RulesStocks

United States tax provisions limiting the ability to offset losses from activities in which the taxpayer does not materially participate against wages, portfolio income or other non-passive income. Disallowed losses are suspended and carried forward to offset future passive income, and are generally released in full when the taxpayer disposes of the entire interest in the activity in a taxable transaction. Rental activity is treated as passive by default, with exceptions defined in the Internal Revenue Code and its regulations.

PassportingStocks

The arrangement under which a financial firm authorised in one European Economic Area state may provide services or establish a branch in another without obtaining separate authorisation there. Supervision of the firm's prudential soundness stays with the home state regulator while conduct rules of the host may apply, which is what makes a single authorisation workable. It rests on the underlying directives, so a firm outside the arrangement must rely on local authorisation, a subsidiary, or a third-country equivalence regime.

Payer SwaptionOptionsStocks

An option to enter an interest rate swap as the fixed-rate payer and floating-rate receiver, at a strike rate fixed at the outset. It gains value when swap rates rise above the strike, because the holder can then lock in paying the lower agreed rate, so it behaves like a call on rates and a put on bond prices. Borrowers use it to cap the cost of future fixed-rate funding, and settlement can be by entering the swap or by cash payment of its value.

PingingStocksCrypto

Sending small immediate-or-cancel orders into a dark pool or hidden book to detect whether a large resting order is present, inferring its existence from whether the probe executes. A fill signals hidden liquidity at that price, which the sender can then trade against or trade ahead of elsewhere. Venues counter it with minimum order sizes, anti-gaming logic, participant segmentation and randomised delays, and regulators have examined the practice under rules on manipulative and deceptive conduct.

PledgeStocks

A security interest created by delivering possession or control of an asset to a lender while ownership stays with the borrower, so the lender may sell it to satisfy the debt on default. Securities, deposits and documents of title are secured this way, and for book-entry securities control is established through the custodian or an account control agreement rather than physical delivery. The lender's rights over the collateral, including any right to reuse it, come from the agreement and the governing law.

Political Risk InsuranceStocksCrypto

Cover for losses to a cross-border investment or trade receivable caused by government action rather than by commercial performance. Insured perils typically include expropriation or nationalisation, restrictions on converting or transferring currency, breach of contract by a state entity, and damage from political violence or war. Policies are written by specialist private insurers and by national export credit agencies and multilateral bodies, and they generally require the investor to pursue available legal remedies before a claim is paid.

Portfolio ReinsuranceStocks

A transaction in which an insurer cedes a whole defined block of business to a reinsurer rather than individual risks, transferring the premium and the liabilities of that block together. It is used to exit a line of business, release capital tied up in reserves, or transfer the run-off of policies no longer written. Where in-force policies are involved, the ceding insurer usually stays liable to policyholders unless the transfer is sanctioned under a statutory portfolio transfer process.

Positive CarryStocksCrypto

A position whose income exceeds the cost of financing and holding it, so it earns money while simply being held. Borrowing at a short-term rate to hold a longer-dated bond yielding more produces it, as does holding a currency with a higher deposit rate funded in one with a lower rate. The earning is compensation for the risks that make it possible, chiefly the chance that the asset price falls or the financing rate rises before the position is closed.

Preferential DebtStocks

Claims that insolvency law places ahead of ordinary unsecured creditors and, in some jurisdictions, ahead of holders of floating charges. Typical categories include limited amounts of unpaid employee wages and holiday pay, contributions owed to occupational pension schemes, and certain taxes collected on behalf of the state. The categories and any caps are set by statute and change over time, so recovery analysis on unsecured bonds has to account for whatever currently ranks above them in the relevant jurisdiction.

Premium TaxStocks

A tax levied on insurance premiums, charged as a percentage of the premium and usually collected by the insurer from the policyholder and remitted to the taxing authority. It substitutes for sales or value added tax, from which insurance is generally exempt. Rates differ by class of business and by jurisdiction, and where a risk is located in one place and the insurer in another, allocation rules decide which authority is owed. Rates are set by each jurisdiction's legislature and revised periodically.

Premiums In ForceStocks

The total annualised premium on policies that are currently active at a measurement date, regardless of how much has been earned or collected so far. It measures the size of the book being carried rather than income for a period, which is what separates it from written premium (contracted during the period) and earned premium (attributable to expired exposure). Analysts track it to see whether the portfolio is growing or shrinking once cancellations and non-renewals are taken into account.

Present Expected ValueStocksCrypto

The probability-weighted average of an uncertain future cash flow, discounted to today at a rate appropriate to its risk and timing. It combines two steps: forming the expectation across possible outcomes, then applying a discount factor. The order of the two does not change the arithmetic because both operations are linear. Under a risk-neutral measure the probabilities are adjusted so that the discount rate can be the risk-free rate, which is the basis on which derivative prices are computed.

Presenting BankStocksCrypto

The bank that presents a documentary collection to the buyer for payment or acceptance in a trade finance transaction. The exporter's bank forwards the documents with instructions, and the presenting bank releases them only against payment, or against the buyer's acceptance of a time draft, so the buyer cannot take delivery of the goods without committing to pay. It acts purely on instructions and does not guarantee payment, which is what separates a collection from a letter of credit.

Price CompressionStocks

A narrowing of the price or yield gap between instruments of different quality or characteristics, so that weaker credits trade closer to stronger ones. It typically occurs when demand for yield pushes investors down the quality scale faster than issuance can absorb them, leaving less differentiation for the same underlying risk. The consequence is that investors receive less compensation per unit of credit risk, and the gaps tend to widen sharply again once conditions change.

Price ElasticityStocks

A measure of how much the quantity demanded or supplied of a good changes when its price changes, calculated as the percentage change in quantity divided by the percentage change in price. Demand is called elastic when the ratio exceeds one in absolute value, meaning quantity moves proportionally more than price, and inelastic when it is below one. It determines whether a price rise increases or reduces total revenue, and it governs how the burden of an indirect tax is split between buyers and sellers.

Price Level AccountingStocks

A reporting approach that restates historical cost figures into units of current purchasing power using a general price index, so amounts recorded in different periods become comparable. It adjusts non-monetary items such as inventory and fixed assets and recognises the gain or loss from holding monetary items during inflation. It was mandated or encouraged in several countries during high-inflation periods and largely abandoned afterwards, though standards still require it for entities reporting in hyperinflationary economies.

Price SupportFuturesStocks

A government measure that keeps the price of a commodity above the level the market would set, using purchases into public stockpiles, minimum purchase guarantees, payments that make up the difference to a target price, or restrictions on supply. Holding a price above equilibrium creates surplus output that has to be bought, stored, exported or destroyed, so the fiscal cost rises with the gap. For traders it distorts the futures curve, since accumulated public stocks can be released later.

Primary OfferingStocks

A sale of newly created securities in which the proceeds go to the issuer, increasing its capital and, for equity, the number of shares outstanding. It contrasts with a secondary sale, where existing holders sell their shares and the company receives nothing. An initial public offering can contain both components, and the split matters to investors because only the primary portion funds the business while the secondary portion shows what existing owners are choosing to do.

Private Limited CompanyStocks

A company with limited liability whose shares may not be offered to the public and are usually subject to transfer restrictions written into its articles. Because it does not raise capital from public markets it faces lighter disclosure requirements than a public company, though it must still file accounts and register details of directors and ownership in most jurisdictions. Re-registering as a public company is the step required before a flotation, and it brings the fuller disclosure regime with it.

Product Guarantee InsuranceStocks

Cover for the cost of repairing, replacing or refunding a product that fails to perform as warranted, including the expense of a recall where that is insured. It responds to the financial consequence of the product not working, which distinguishes it from product liability cover, which responds to injury or damage the product causes to people or other property. Insurers underwrite it on the manufacturer's testing, quality control and claims history, and exclusions for known defects are standard.

Prospective Finite PolicyStocks

A finite risk reinsurance contract covering losses that have not yet occurred, under which the cedant pays premium into an experience account that accumulates at an agreed rate and funds its own claims, with the reinsurer taking only limited risk above that. Because most of the economics is the timing of the cedant's own money rather than genuine transfer, accounting standards require a contract to transfer significant insurance risk before it can be reported as reinsurance rather than as a deposit.

Protection PaymentStocks

In a credit default swap, the amount the protection seller owes the buyer once a credit event on the reference entity has been determined. Settlement is usually by auction: a market-wide process establishes the final price of the defaulted obligations, and the seller pays the difference between par and that price on the contract notional. Cash flowing the other way, the buyer's periodic fee, is the premium leg, so the two sides of the contract are named and valued separately.

Protective StopStocksCrypto

A resting stop order placed against an open position to cap the loss if price moves against it, becoming a market or limit order once the trigger price trades. Placement is normally derived from the position's own structure, such as beyond a recent swing point or a multiple of average true range, rather than from a round loss figure. It does not fix the exit price: a gap through the trigger fills at the next available price, which can be materially worse than the level set.

Public OfferingStocks

A sale of securities to investors generally, made under a registration statement or prospectus reviewed by the securities regulator and accompanied by prescribed disclosure. Anyone eligible in the relevant market may buy, which separates it from a private placement sold to a restricted group under an exemption. It covers both a company's first sale of shares and later issues of equity or debt, and the disclosure and liability regime attached to the prospectus is what the registration requirement exists to deliver.

Pup CompanyStocksCrypto

An insurance subsidiary formed and wholly owned by a larger insurer to write business the parent prefers to keep separate, such as a different class, a different rating tier, or a particular state's market. Keeping it in a separate licensed entity means separate rate filings, separate statutory accounts and separate capital, so its results and pricing do not mix with the parent's own book. Its obligations are its own unless the parent has given an explicit guarantee.

Put On The MinimumOptionsStocks

A fixed-strike lookback put whose payoff is the greater of zero and the strike minus the lowest price the underlying reached during the observation period. Because settlement uses that minimum rather than the price at expiry, a decline captured at any point in the contract's life is retained even if the underlying recovers before maturity. The retrospective feature makes it more expensive than an otherwise identical standard put, and valuation requires the distribution of the running minimum rather than only the terminal price.

Put ProvisionStocks

A bond term giving the holder the right to require the issuer to redeem, usually at par, on stated dates or after a defined event such as a change of control. It caps the price fall from rising yields or deteriorating credit, because the holder can exit at the put price instead of selling into the market, so a putable bond yields less than an otherwise identical straight bond. For the issuer it creates a potential early cash demand that has to be planned for in liquidity terms.

Putable SwapOptionsStocks

An interest rate swap that gives the fixed-rate receiver the right to terminate the contract early on stated dates without making a break payment. That termination right is an embedded option, so the fixed rate is set less favourably to the holder than on a comparable non-cancellable swap, the difference being the option premium spread across the payments. It is used to hedge an asset that may be repaid early, so the hedge can be removed when the asset disappears.

Paris ClubStocks

An informal group of creditor governments that meets to restructure debt owed to them by countries in payment difficulty. It works to agreed principles: cases are considered individually, decisions are taken by consensus, creditors act together rather than separately, and the debtor is expected to have a programme with the International Monetary Fund in place. Its agreed minute is then implemented through bilateral agreements, and it normally requires the debtor to seek comparable treatment from its other creditors.

Price regulationStocks

Government control of the prices a firm may charge, used where competition is absent, most often in utility networks. Rate of return regulation sets prices to cover costs plus an allowed return on the asset base, which protects the firm but weakens the incentive to cut costs. Price cap regulation instead fixes an allowed path, commonly inflation less an efficiency factor, over a review period, so the firm keeps savings it makes within that period. For investors, the regulatory determination drives allowed revenue and therefore cash flow.

Profit maximisationStocks

The assumption that a firm chooses output, price and inputs to make the gap between total revenue and total cost as large as possible. The condition is that marginal revenue equals marginal cost with marginal cost rising through that point; under perfect competition marginal revenue equals price, so the firm produces where price equals marginal cost. Corporate finance restates the objective as maximising the present value of future cash flows, since a single-period figure ignores timing, risk and the investment needed for later periods.

PropensityStocks

The fraction of income allocated to a given use. The average propensity to consume is consumption divided by income; the marginal propensity to consume is the share of an additional unit of income that is spent, with the remainder saved, so the marginal shares of spending and saving sum to one. The marginal figure drives the multiplier in Keynesian models, since a higher spending share means each round of income generates more of the next. Estimates differ by income level and by whether a change is seen as temporary.

Pension Plan Withdrawal CreditsStocks

The portion of accrued pension benefits a departing member is entitled to take out of a plan, usually as a transfer to another arrangement or as a cash lump sum where the rules allow it. The amount reflects service completed and the plan's vesting schedule, so an employee who leaves before vesting may forfeit employer-funded portions. Tax treatment depends on the jurisdiction and on whether the money is moved into another qualifying plan.

PIMCOStocks

Pacific Investment Management Company, an asset manager founded in 1971 in Newport Beach, California, widely known for actively managed fixed income mutual funds, exchange-traded funds and institutional mandates. It became a subsidiary of the German insurer Allianz in 2000 and manages money for pension plans, insurers, sovereign funds and retail investors. Its published commentary on interest rates and credit cycles is widely followed because of the size of the bond portfolios it runs.

Paid-Up Additional InsuranceStocks

Extra whole life coverage bought with a policy dividend or an optional rider payment, requiring no further premiums once purchased. Each addition carries its own death benefit and cash value, and because the insured is charged at their attained age, the amount of coverage bought per dollar falls as they get older. The additions themselves earn dividends, so participating policyholders use them to compound coverage and cash value inside the original contract.

Pareto Efficiency(Pareto Optimality) OptionsStocks

An allocation of resources in which no rearrangement can make one party better off without making another worse off. It is the standard used in welfare economics to judge whether an outcome leaves potential gains from trade unexploited. Reaching it says nothing about fairness: an allocation giving nearly everything to one person can satisfy the condition. A change that helps at least one party and harms none is called a Pareto improvement.

Passive Foreign Investment Company(PFIC) Stocks

A non-United States corporation that fails either of two Internal Revenue Code tests: most of its gross income is passive, such as interest, dividends and rents, or most of its assets produce passive income. Many offshore funds meet the definition. A US shareholder faces punitive default treatment on distributions and gains, including an interest charge on deferred tax, unless an election such as qualified electing fund or mark-to-market is made and annual reporting is filed.

Pay Yourself FirstStocks

A budgeting method in which saving is treated as the first bill of the month rather than whatever is left at the end. The saver sets an automatic transfer from the paycheck or checking account into a savings, brokerage or retirement account on payday, then spends from the remainder. The mechanism works by removing the decision from each spending moment. It does not increase income, so the transfer amount still has to fit actual cash flow.

PayeeStocksCrypto

The party named to receive a payment under a cheque, draft, bill of exchange, note or electronic transfer. The payer or drawer names the payee on the instrument, and only that party, or someone to whom they endorse it, can obtain the funds. On a life insurance or annuity contract the term describes the person entitled to the proceeds. Naming the payee precisely matters because banks verify it against the presenting party.

PaymentStocks

The transfer of value from a payer to a payee to settle an obligation, made in cash, by bank transfer, card, cheque or digital token. A payment has two stages that are often confused: clearing, when instructions and amounts are exchanged and netted, and settlement, when funds actually move and the obligation is legally discharged. Whether a payment can be reversed, and how long settlement takes, depends on the network carrying it.

Payroll TaxStocks

A tax levied on wages and salaries, usually split between employer and employee and withheld by the employer at each pay run. In the United States the main components fund Social Security and Medicare, with the Social Security portion applying only up to an annual wage cap and the Medicare portion applying to all covered wages. Rates and the wage cap are set by statute and adjusted periodically, so current figures must be checked with the authority.

Penetration PricingStocks

A launch strategy that sets an introductory price well below the expected long-run level to win volume and market share quickly, then raises it once buyers are established. It works where demand is price sensitive, unit costs fall with scale, or switching costs lock customers in afterwards. The trade-off is thin or negative early margins and the risk that customers anchor on the low price and resist the later increase.

Periodic Interest RateStocks

The interest rate applied to a balance in one compounding period rather than over a full year. It equals the nominal annual rate divided by the number of periods per year, so a stated annual rate of twelve percent compounded monthly gives a periodic rate of one percent. Because interest credited in one period joins the balance for the next, the effective annual rate exceeds the nominal rate whenever compounding happens more than once a year.

Perseroan TerbatasStocks

The Indonesian limited liability company, abbreviated PT, in which capital is divided into shares and shareholders are liable only up to the amount they subscribed. It is formed by notarial deed and approved by the Ministry of Law, and is run by a board of directors with a separate board of commissioners supervising them. A publicly listed one adds Tbk to its name, while a foreign owned investment company takes the PT PMA form.

Personal Financial StatementStocks

A document listing an individual's assets, liabilities and resulting net worth at a point in time, often paired with a statement of income and expenses. Lenders request one when underwriting a business loan, a personal guarantee or a large mortgage, and regulators require it from certain corporate insiders. Assets are usually reported at estimated current value rather than historical cost, which is the main way it differs from a company balance sheet.

Personal Identification Number(PIN) Stocks

A numeric code that authenticates a cardholder or account holder to a bank, ATM or payment terminal. It supplies one of two factors in a card transaction: possession of the card and knowledge of the code. The issuer never stores it in readable form. Instead the entered digits are encrypted inside the terminal's secure hardware and verified against a stored cryptographic value. Sharing it typically shifts liability for unauthorised withdrawals to the customer.

Position TraderStocksCrypto

A trader who holds a directional position for weeks, months or longer, aiming to capture a sustained trend rather than intraday movement. The approach relies on higher-timeframe charts, fundamental or macro drivers, and wider stops, so it needs smaller position sizes relative to account equity and tolerates larger interim drawdowns. It generates few transactions, which lowers commission and spread costs, and it exposes the position to overnight gaps and financing charges.

Positive EconomicsOptionsStocks

The branch of economics that describes and tests what is, using statements that can in principle be verified or falsified against data, such as how a tax change affects consumption. It is set against normative economics, which makes value judgments about what policy ought to be. The distinction matters because a shared positive finding can still support opposite policy conclusions once different value judgments are applied to it.

Positive PayStocks

A cash management service in which a company sends its bank a file of issued cheques listing number, date and amount, and the bank pays only items matching that list. Anything that does not match is flagged as an exception for the company to accept or return. Payee positive pay extends the match to the payee name. The service is a fraud control against altered and counterfeit cheques, moving detection to before funds leave the account.

Post-Trade ProcessingStocksCrypto

Everything that happens between the moment a trade is agreed and the moment cash and securities have changed hands: confirmation and affirmation of terms, allocation to underlying accounts, clearing and netting through a central counterparty, settlement at the depository, and recording of positions. Errors and mismatches are resolved here, and the length of the settlement cycle determines how long counterparty risk stays open. Reconciliation and corporate action processing continue after settlement.

Poverty TrapStocksCrypto

A self-reinforcing situation in which being poor makes it harder to stop being poor. It arises when earning more triggers withdrawal of means-tested benefits or tax credits, so extra earnings raise disposable income by very little, producing a high effective marginal tax rate. It also arises at country level when low income prevents the saving and investment that would raise productivity. Benefit tapers and phase-outs are designed to soften the effect.

Predatory PricingStocks

Setting a price below cost with the aim of driving competitors out of a market and then raising prices once rivals have exited. Competition authorities treat it as an abuse only where the seller has market power and could plausibly recoup the losses later, because low prices normally benefit buyers. Proving it requires showing pricing below an appropriate measure of cost and a realistic path to recoupment, which is why such cases are difficult to bring.

Present Value Interest Factor of Annuity(PVIFA) Stocks

A multiplier that converts a stream of equal periodic payments into a single present value. It equals one minus the discount factor for the final period, all divided by the periodic rate, and assumes payments arrive at the end of each period. Multiplying the payment by this factor gives the lump sum today that is financially equivalent to the whole stream. It underlies loan amortisation, bond pricing and pension valuation.

Preservation of CapitalStocks

An investment objective that prioritises avoiding nominal loss of the amount invested over seeking growth. Portfolios built around it concentrate in short-dated government securities, insured deposits, money market instruments and high-grade bonds held to maturity, where price variation is small and repayment risk is low. The trade-off is that returns may not keep pace with inflation, so purchasing power can still fall even when the nominal balance is intact.

Price elasticity of supplyStocks

A measure of how strongly the quantity producers offer responds to a change in price, calculated as the percentage change in quantity supplied divided by the percentage change in price. A value above one means supply is elastic and output adjusts more than proportionally. It rises with spare capacity, availability of inputs, ease of storage, and above all with time, since producers can add capacity over a long horizon but not overnight.

Private Finance InitiativeStocks

A procurement model developed in the United Kingdom under which a private consortium designs, builds, finances and operates a public asset such as a hospital or road, and the public authority pays a unitary charge over a long concession. The state avoids upfront capital outlay and transfers construction and availability risk, but commits to a long stream of payments. Critics point to high financing costs and contracts that prove inflexible as needs change.

Private SectorStocks

The part of an economy owned and run by individuals and companies rather than by the state, comprising sole traders, partnerships, private and listed companies, cooperatives and non-profits. Its organisations are financed by owners, retained profits and capital markets rather than by taxation, and they are directed by profit or by their members' purposes. In national accounts it is measured separately from general government and public corporations.

PrivatizationStocks

The transfer of ownership or control of an asset, enterprise or service from the state to private hands, by public share offering, trade sale, management buyout or long-term concession. Governments use it to raise proceeds, cut subsidies and expose an activity to competitive pressure. Where the activity is a natural monopoly, a regulator is usually created at the same time to set prices and service standards, since a change of ownership alone does not create competition.

Producer SurplusStocks

The difference between what producers receive for the units they sell and the minimum they would have accepted, shown as the area between the market price and the supply curve up to the quantity traded. It measures the gain from trade accruing to sellers, and combined with consumer surplus it gives total welfare in a market. A price floor, a tax or a binding quota changes its size, which is how the effect of such policies is assessed.

Product Life CycleOptionsStocks

The stages a product passes through from launch to withdrawal: introduction, growth, maturity and decline. Sales, margins, competitive intensity and the appropriate marketing spend differ at each stage, so the model is used to plan pricing, capacity and reinvestment. Analysts apply it to judge when revenue growth will slow and cash generation will peak. Its weakness is that stage boundaries are only visible after the fact and some products never follow the pattern.

Profit Before Tax(PBT) Stocks

A company's earnings after deducting cost of sales, operating expenses, depreciation, amortisation and interest, but before any charge for income tax. It sits between operating profit and net income on the income statement. Because tax charges vary with jurisdiction, loss carryforwards and one-off settlements, this line is used to compare underlying performance across companies and periods without those distortions. It still includes financing costs, so it is not neutral to capital structure.

PromotionStocks

The element of the marketing mix covering all communication used to inform buyers about a product and persuade them to buy: advertising, public relations, sales promotion, direct marketing and personal selling. Companies budget it as a share of revenue and judge it by measured response such as incremental sales or customer acquisition cost. In an employment context the same word describes an employee's advancement to a role carrying greater responsibility and pay.

Property InsuranceStocks

Coverage that indemnifies the owner or user of physical property for loss or damage from named or all-risk causes such as fire, storm, theft and vandalism, and usually for resulting loss of use. The contract sets a limit, a deductible the insured retains, and a valuation basis: replacement cost pays to rebuild with new materials, while actual cash value deducts depreciation. Standard exclusions commonly include flood, earthquake, war and ordinary wear.

Public GoodStocks

A good with two properties: consumption by one person does not reduce what is available to others, and non-payers cannot practically be excluded from it. National defence, street lighting and a lighthouse are the standard examples. Because free riding is possible, private markets tend to undersupply such goods, which is the economic argument for tax funding or public provision. Goods meeting only one of the two conditions are called club goods or common resources.

Public Limited Company(PLC) StocksCrypto

A company incorporated in the United Kingdom, Ireland or a similar jurisdiction that is permitted to offer its shares to the public, denoted by the suffix plc after its name. It must meet a statutory minimum share capital, appoint at least two directors and a qualified company secretary, and file fuller accounts than a private company. It may list on an exchange but is not required to, and listing brings a separate set of obligations.

Public debtStocks

The portion of a government's borrowing held outside the government itself, meaning securities owned by domestic and foreign investors, banks, pension funds and central banks. It is distinguished from gross debt, which also counts intragovernmental holdings such as bonds sitting in public trust funds. Because only the externally held portion requires interest payments to outside parties, it is the measure most often compared with annual output when assessing fiscal capacity.

Purchase-Money MortgageStocks

A loan extended by the seller of a property to the buyer as part of the purchase, secured by the property itself rather than provided by a bank. The buyer signs a note and a mortgage or deed of trust to the seller and pays under agreed terms, often with a balloon payment. Buyers use it when they cannot qualify for conventional financing. The seller carries default risk but may foreclose, and the loan can rank behind an institutional first mortgage.

Push Down AccountingStocks

A method in which an acquired company restates its own separate financial statements to the new basis established by the buyer, so the purchase price allocation, including revalued assets and any goodwill, appears in the subsidiary's books rather than only in consolidated accounts. It is optional under United States rules and is elected when a change of control occurs. It generally raises depreciation and amortisation in the subsidiary, lowering its reported post-acquisition earnings.

Petty CashStocks

A small amount of currency an organisation keeps on hand to pay minor expenses such as postage, taxi fares and supplies, where raising a purchase order or cheque would cost more than the item itself. It is normally run on an imprest system: the fund is set at a fixed amount, a receipt is collected for every disbursement, and it is topped back up by the total of the receipts, which is the point at which the expenses are recorded.

Passive StrategyStocksCrypto

An approach that holds a broad market portfolio and trades only to reflect changes in the index or in cash flows, rather than attempting to identify mispriced securities. Its case rests on the arithmetic that all investors together hold the market, so active positions sum to zero before costs and are negative after them, and on the argument that public information is already reflected in prices. Implementation still involves choices: index construction, replication method, securities lending policy and rebalancing all affect the result relative to the stated benchmark.

Personal TrustStocks

An arrangement in which an individual transfers assets to a trustee to hold and manage for named beneficiaries under the terms of a trust deed. The trustee holds legal title and owes fiduciary duties of loyalty and care, while the beneficiaries hold the economic interest. Uses include managing assets for minors, providing for a surviving spouse while directing the remainder elsewhere, and holding property outside probate. Tax treatment varies by jurisdiction and by whether the trust is revocable, and a revocable trust generally does not remove assets from the settlor's taxable estate.

Policy InstrumentStocks

A variable a policymaker can control directly and uses to pursue a target it cannot control. For a central bank the instrument is typically the overnight interest rate or the quantity of reserves, while the target is inflation or nominal income, and the link between them runs through intermediate variables such as credit growth and expectations. Choosing an instrument involves a trade-off: controlling a price means accepting whatever quantity results, and controlling a quantity means accepting the price, so a shift between them changes which shocks the market absorbs.

Portfolio Opportunity SetStocksCrypto

The full range of expected return and standard deviation combinations obtainable from a given group of assets by varying the weights. Plotting it in mean and standard deviation space produces a region bounded on the left by the minimum variance frontier, and its upper edge above the minimum variance point is the efficient frontier. Its shape depends on the correlations between the assets: the lower they are, the further the boundary bows to the left, which is the geometric expression of the diversification benefit. Adding a risk-free asset extends the set along a straight line.

Trading in contracts that reference a commodity without an expectation of physical delivery, so positions are closed out or cash settled rather than resulting in a cargo changing hands. Volumes there typically exceed the underlying physical trade many times over, because hedgers and speculators can enter and exit without handling the goods. Prices in the two markets are linked by the ability to deliver at expiry, and the gap between them is basis risk.

Passive RetentionStocksCrypto

Bearing a risk without having decided to, because it was never identified, was wrongly assumed to be insured, or falls into a gap between policies. It differs from active retention, where an organisation deliberately keeps an exposure because insuring it costs more than the expected loss. The danger is that no reserve, capital allocation or mitigation plan sits behind it, so the first indication is usually the loss itself.

Pay Later Option(contingent premium option) OptionsStocks

An option for which no premium is paid at the outset: the buyer pays only if the contract finishes in the money, with the premium deducted from the payout or invoiced at expiry. Because the seller collects nothing in the losing states, the contingent premium is larger than an ordinary up-front premium. A holder whose option finishes barely in the money can end up with a net loss, since the premium falls due in full once the strike is passed.

Payment TermsStocks

The contractual conditions setting when an invoice must be settled, the method of payment, any discount for early settlement and the interest or charges applied to late payment. They determine how long the seller finances the buyer, so they feed directly into working capital: lengthening terms improves the buyer's cash conversion cycle at the supplier's expense. In cross-border trade they also specify the currency and whether documentary credit or open account applies.

PD(probability of default) Stocks

Abbreviation for probability of default, the estimated chance that a borrower fails to meet its obligations over a stated horizon, usually one year. It is one of the three inputs to expected credit loss, alongside loss given default and exposure at default, and multiplying the three gives the expected loss on a facility. Estimates come from internal rating models, agency transition data or market-implied measures derived from bond spreads and credit default swaps.

Pension SystemStocks

The overall architecture through which a country provides retirement income, usually described in pillars: a state scheme financed from taxes or contributions and paid out of current revenue, occupational schemes sponsored by employers and funded by invested assets, and voluntary personal saving. The balance between them determines how much retirement income depends on demographics and public finances versus on investment returns, and reform typically shifts risk between the state, employers and individuals.

Per Pro(per procurationem, p.p.) Stocks

A notation placed before a signature to show that the person signing does so on behalf of another under delegated authority, rather than in their own right. It appears on cheques, contracts and correspondence signed by a subordinate for an absent principal. The signature binds the principal only to the extent of the authority actually granted, so a counterparty relying on it should confirm the signatory's mandate before treating the document as effective.

Percentage of Loss DeductibleStocks

A deductible expressed as a share of the loss itself rather than as a fixed sum, so the amount the insured bears rises with the size of each claim. It keeps the policyholder financially involved at every loss level, which limits inflated claims and the temptation to relax loss control on large exposures. Contracts often add a minimum and maximum in money terms so the retained amount cannot become trivial or ruinous.

Perpetual DebentureStocks

A debt security with no fixed redemption date, so the issuer pays interest indefinitely and repays principal only on liquidation or by exercising a call. Value therefore rests entirely on the coupon stream, which makes the price extremely sensitive to interest rates and to the issuer's credit. Investors realise capital by selling in the secondary market rather than by waiting for maturity, and any call feature caps the price when rates fall.

Perpetual SuccessionStocks

The characteristic of an incorporated body that it continues to exist regardless of changes among its members, so shares can be transferred, directors replaced and shareholders can die without affecting the entity's contracts, property or licences. It is a direct consequence of separate legal personality and it is what makes corporate securities transferable without renegotiating every agreement the company holds. The entity ends only through formal dissolution, striking off or liquidation.

PetrodollarsOptionsStocks

The United States dollar revenues oil-exporting countries earn from crude sales, so named because oil is priced and settled in dollars internationally. Because those receipts often exceed what an exporter can spend domestically, the surplus is recycled into international bank deposits, sovereign wealth funds and foreign securities. That recycling channelled large flows into the eurodollar market and into lending to developing countries during the 1970s and remains a source of cross-border capital today.

PIG(passive income generator) Stocks

Abbreviation for passive income generator, an investment held mainly to produce income of a type that United States tax rules classify as passive, so it can be set against passive losses from other holdings that would otherwise be suspended. The passive activity loss rules restrict deducting such losses against wages or portfolio income, which is what creates the demand for offsetting passive income. Suitability depends on the individual's circumstances and should be confirmed with a tax adviser.

Placed BusinessStocks

Insurance that a broker has successfully arranged with underwriters, meaning terms are agreed and the risk is on cover, as opposed to enquiries still being quoted or declined. Brokers track the proportion of enquiries that convert to placed business as a measure of market appetite and of their own effectiveness. In subscription markets a risk may be only partly placed, with the broker still seeking underwriters to complete the remaining share of the line.

Point Barrier OptionOptionsStocks

A barrier option whose trigger is tested only at specified moments, most often a single observation date or a set of fixing times, rather than continuously through the life of the contract. Discrete monitoring makes the option worth more than a continuously monitored knock-out and less than a knock-in, because the price can cross the level between observations without effect. It also makes the barrier easier to influence around the fixing, so contracts define the observation source precisely.

Potential Market RiskStocksCrypto

An estimate of how far a contract's value could move against a firm over a future horizon, used to size the exposure a counterparty relationship may generate before any loss has occurred. It is measured by simulating market factors forward to a confidence level and taking the resulting replacement cost, then adding it to current mark-to-market exposure. Credit limits are set against this forward-looking figure rather than against today's value alone.

Premium CapacityStocks

The maximum volume of premium an insurer or a market can write, given its capital, its reinsurance protection and any regulatory limit on the ratio of premium to surplus. Capacity expands when capital enters after profitable years and contracts after large losses, which is the mechanism behind the underwriting cycle: scarce capacity raises rates and tightens terms, and the resulting profits attract new capital that competes rates down again.

Presettlement RiskStocksCrypto

The risk that a counterparty defaults before a contract reaches settlement, leaving the surviving party to replace the trade at whatever the market price has become. The loss is the cost of replacement rather than the notional amount, so it depends on how far prices have moved since the trade was struck and on the remaining life. It is managed with collateral, netting agreements and exposure limits, and it precedes settlement risk, which arises only during the exchange itself.

Primary LayerStocks

The bottom section of an insurance or reinsurance programme, responding first to a loss above any deductible and up to its own limit, with excess layers attaching only once it is exhausted. Because it is hit by frequent as well as severe claims, it carries the highest expected loss cost and the highest rate per unit of limit, and it is where the insurer's claims handling and loss control effort concentrates.

Prime RateStocks

A benchmark lending rate that commercial banks publish and use as the base for pricing many business and consumer loans, with individual borrowers charged the prime rate plus a spread reflecting their credit. In the United States it has moved as a fixed margin over the Federal Reserve's target for overnight rates, so it steps up and down with policy decisions rather than trading continuously. Rates on credit cards and home equity lines are commonly tied to it.

Principal Protected BondStocks

A structured note that promises return of the face amount at maturity while paying a return linked to an equity index, basket or other reference. It is typically built from a zero coupon bond that grows to par plus an option funded by the remaining proceeds, which is why participation in the index is partial. The protection is only as good as the issuer's credit, and selling before maturity means taking the market price rather than par.

Prior-Period AdjustmentsStocks

Corrections to financial statements of earlier periods for a material error or a change in accounting policy, made by restating the comparative figures and adjusting the opening balance of retained earnings rather than by running the amount through current profit. Handling it this way keeps the current year's reported performance free of items that belong to earlier periods. Disclosure of the nature of the correction and the amount restated for each line is required.

Pro FormaStocks

A presentation of financial information on a hypothetical or adjusted basis, showing what results or position would look like under stated assumptions such as a completed acquisition, a refinancing or the exclusion of items management considers non-recurring. It is a supplement to, not a substitute for, statements prepared under accounting standards. Regulators require the reconciliation to the reported figures and prohibit presentations that give the adjusted numbers more prominence than the audited ones.

Process RiskStocksCrypto

The exposure to loss from failures in how work is actually carried out: manual steps, handoffs between systems, reconciliations, approvals and controls that break down under volume or change. It is a component of operational risk and it is measured by mapping each process, identifying failure points, and tracking incidents and near misses. Mitigation runs to automation, segregation of duties, four-eyes checks and reconciliation to independent sources rather than to insurance alone.

Product Liability InsuranceStocks

Cover for the legal liability a manufacturer, distributor or retailer incurs when a product it supplied causes injury or damage to property, paying damages and defence costs up to the policy limit. Liability can attach without proof of negligence in jurisdictions applying strict liability to defective goods. Underwriting looks at the product's use, the markets it reaches, the recall history and quality control, and cover is normally arranged with a per-claim and an annual aggregate limit.

Profit ForecastStocks

A published estimate of a company's earnings for a stated future period, made either by the company itself or by analysts covering it. Company forecasts are treated as formal statements in several markets: under the UK Takeover Code a forecast issued during an offer must be reported on by advisers and then repeated or withdrawn as circumstances change. Analysts build their own from revenue drivers, margin assumptions and financing costs, and the consensus of those estimates becomes the benchmark against which reported results are judged when they arrive.

ProfiteerStocks

A seller who charges prices far above normal levels by exploiting scarcity, emergency or wartime conditions rather than by adding value or bearing extra cost. The label is a political and legal judgment rather than an accounting one, and governments respond with price-gouging statutes, excess profits taxes or windfall levies that claw back part of the gain. For investors the accusation matters mainly as a regulatory and reputational exposure, because it often precedes price controls or special taxation of a whole sector.

Promised YieldStocks

The return a bondholder would earn if the issuer paid every coupon and the principal in full and on schedule, and if each coupon were reinvested at that same rate. It is the yield to maturity quoted at purchase, so it describes a contractual promise rather than an expectation. Any default, deferral or reinvestment at a different rate produces a realized return above or below it. Comparing it with expected yield, which weights default scenarios by probability, isolates the credit risk premium embedded in a bond's quoted return.

Proof of LossStocks

A formal statement a policyholder files with an insurer setting out what was damaged or lost, when and how it happened, and the amount claimed, signed and supported by documents such as invoices, photographs or police reports. Policies set a deadline for filing after the loss, and the insurer's obligation to pay generally does not begin until a satisfactory statement is received. It converts a reported incident into a measurable claim the insurer can investigate, value and hold reserves against.

ProtestStocksCrypto

A formal certificate drawn up by a notary recording that a bill of exchange or promissory note was presented for acceptance or payment and was refused. The document states the date, the demand made and the answer given, and it preserves the holder's right of recourse against endorsers and the drawer. In trade finance a protested bill is the standard evidence of dishonour used to support later legal action for recovery, and the requirement to obtain one is often waived expressly in the instrument.

Prudential RatioStocks

A regulatory ratio a bank or insurer must keep at or above a minimum set by its supervisor, designed to limit the chance of failure rather than to measure profitability. Examples include capital measured against risk-weighted assets, a leverage ratio against total exposure, and liquid assets against projected stressed outflows. Each pairs a defined numerator of loss-absorbing or liquid resources with a denominator representing exposure. The required minimum comes from legislation or supervisory rules and is revised periodically as standards change.

Public SectorStocks

The part of an economy owned or controlled by government, covering central and local administration, state agencies and enterprises the state owns. It is financed by taxation, borrowing and charges rather than by shareholder capital, and its borrowing requirement feeds the supply of government bonds that anchors domestic interest rates. For investors its size matters because state spending, procurement and pay settlements shape demand in whole industries, and because public borrowing competes with private issuers for the same pool of savings.

Puke PointStocksCrypto

Trading slang for the level of loss at which a holder abandons a position and sells regardless of valuation, driven by pain rather than analysis. It marks the end of a sequence in which an investor first denies the loss, then rationalizes it, then capitulates. Clusters of these forced exits show up as volume spikes and price gaps, because many holders reach the limit of their tolerance at similar levels. Position limits and predefined exit rules exist precisely to move that decision away from the moment.

Pure Bond Value(investment value, bond floor) Stocks

The value a convertible bond would have if its conversion right were stripped away, found by discounting the coupons and redemption amount at the yield the market demands from an ordinary bond of the same issuer, maturity and seniority. It acts as a floor under the convertible's price: as the share falls, the convertible converges toward this level and stops tracking the equity. The gap between the market price and it is the value the market attributes to the conversion option.

Parisian OptionOptionsStocks

A barrier option that knocks in or out only after the underlying has stayed beyond the barrier for a specified length of time, rather than the instant the level is touched. The clock may require one continuous spell past the barrier or, in the cumulative variant, total time spent there across the life of the contract. Requiring persistence makes the contract far harder to trigger with a brief spike or a single manipulated print, so its value depends on the whole path of the underlying.

Positional GoodsStocks

Goods whose value to the owner depends on how few other people have them, so satisfaction comes from relative standing rather than from the item itself. Prime addresses, scarce artworks and places at selective institutions behave this way: supply cannot expand to meet demand without destroying the scarcity that creates the value. Prices for such assets tend to track the wealth of the richest buyers rather than general incomes, which is why they can rise faster than broad consumer prices for long stretches.

Precautionary MotiveStocks

The reason households and firms hold money beyond what planned spending requires, namely to meet unexpected costs or gaps in income. Keynes set it alongside the transactions and speculative motives as one of three sources of demand for money. Balances held for it rise with uncertainty about future income and with the difficulty of raising cash quickly, and fall as the interest given up on idle money grows. It explains why cash holdings expand during recessions even as spending weakens.

Prepayment FunctionStocks

The equation in a mortgage-backed security model that converts loan and market conditions into a projected rate of early repayment. Inputs typically include the gap between the loan's coupon and current refinancing rates, the age of the loan, the season, and how often the pool has already had the chance to refinance. Its output drives the projected cash flows, so the assumed function determines the estimated average life, yield and duration of the security far more than its stated maturity does.

Price MechanismStocks

The process by which prices coordinate decisions in a market economy, rising when demand exceeds supply and falling when supply exceeds demand until the two balance. Movements act as signals about scarcity, as incentives to produce more or consume less, and as a rationing device deciding who gets a limited quantity. Where prices are held fixed by administration, all three functions are suppressed at once and shortages, queues or unsold surpluses appear in their place.

Progressive TaxationStocks

A tax structure in which the average rate paid rises with income or wealth, usually implemented through bands where successive slices of income face higher marginal rates. Only the slice falling inside each band is taxed at that band's rate, so crossing a threshold never reduces after-tax income on earnings already received. Thresholds and rates are set by legislation and reviewed periodically, and credits, allowances and deductions can make the effective schedule differ substantially from the headline one.

Public SpendingFuturesStocks

Outlays by government on goods, services, investment and transfers, financed by taxation, borrowing or asset sales. Statistics separate current spending on wages and services from capital spending on infrastructure, and both from transfer payments that move money between households without buying anything. Because the state is a very large buyer, changes in its programmes move demand in construction, defence and healthcare directly, and the borrowing needed to fund a deficit adds to the stock of government bonds outstanding.

Public UtilityStocks

A company supplying an essential network service such as electricity, gas, water or fixed telecommunications, usually operating a natural monopoly under a licence that limits what it may charge. Regulators set allowed revenue by estimating an efficient cost base and permitting a return on the capital invested, which makes the business behave more like a regulated bond than a free-market enterprise. Steady rate-linked cash flows follow from that framework, and the periodic price review becomes the dominant event for valuation.

Puttable Bond(put bond) Stocks

A bond giving the holder the right to sell it back to the issuer at a set price on stated dates before maturity. The embedded put protects the investor when yields rise or credit quality deteriorates, because the redemption price is fixed while the bond's market value would otherwise fall. The holder pays for that protection through a lower coupon than an otherwise identical bullet bond, and the security's value equals the straight bond value plus the value of the put option.

posterior distributionStocksCrypto

The probability distribution of an unknown quantity after observed data have been combined with a prior distribution, using Bayes' rule. It is proportional to the prior multiplied by the likelihood of the data under each candidate value, then rescaled so total probability equals one. In finance it is what a Bayesian estimate of an expected return, a default probability or a model parameter actually is: a whole distribution rather than a single number, from which both a point estimate and a credible interval are read off.

prior distributionStocksCrypto

The probability distribution assigned to an unknown quantity before the current data are examined, representing what is believed or assumed at the outset. Bayes' rule multiplies it by the likelihood of the observed data to produce the posterior. A prior can encode genuine earlier evidence, a modeling judgment such as shrinking estimated returns toward a market average, or deliberate vagueness. When data are scarce the prior dominates the answer, and its influence shrinks as the sample grows, which is why the choice matters most in small samples.

prudent man ruleStocks

A fiduciary standard requiring a trustee or investment fiduciary to manage assets with the care, skill and caution a prudent person would apply to their own affairs. Its early form judged each holding on its own merits, which pushed fiduciaries toward conservative individual securities. Later United States law, through the prudent investor rule and the Uniform Prudent Investor Act, moved the test to the portfolio as a whole and to the suitability of the overall risk and return strategy, permitting investments that would look imprudent viewed in isolation.

Parity Bond(parity debt, additional bonds on parity) Stocks

A bond issued with an equal claim on the same pledged revenue as an issuer's existing bonds, ranking alongside them rather than behind. Bond documents normally set an additional-bonds test the issuer must satisfy before more parity debt can be issued.
