R: Glossary Terms

R

restricted stockStocks

Shares subject to transfer, vesting, or resale restrictions imposed by securities law, compensation terms, or contractual agreements.

restricted stock unitsStocks

A compensation award promising an employee a set number of shares once vesting conditions are met, usually time served and sometimes a performance target or a liquidity event. Nothing is owned before vesting. At vesting the shares are delivered and their value is ordinary compensation income, with employers commonly withholding a portion of the shares to cover taxes.

risk-on(risk on) StocksCrypto

Market shorthand for conditions in which investors favor assets perceived as higher risk or more economically sensitive.

risk-off(risk off) StocksCrypto

Market shorthand for conditions in which investors shift toward cash, high-quality bonds, defensive assets, or other perceived safe havens.

reserve order(hidden reserve) StocksCrypto

An order that displays only part of its total quantity while keeping additional size hidden and replenishing the displayed portion after fills.

round lotStocks

The standard trading unit used for quoting and market-structure purposes; for many U.S. stocks this historically has been 100 shares, though definitions can vary by price and rule.

regular trading hoursStocks

The venue's main continuous session, which for United States equities runs from the opening auction at 9:30 a.m. to the closing auction at 4:00 p.m. Eastern time on business days. Official opening and closing prices, index levels and most volume come from this window. Sessions before and after it operate with thinner liquidity and wider spreads.

rebate rateStocks

The interest a securities lender pays back to the borrower on the cash collateral posted against a stock loan. It equals the market rate on that cash minus the lending fee, so an abundant security produces a positive return for the short seller. As the lending fee rises the payment shrinks, and it can turn into a net charge.

Regulation SHO(Reg SHO) Stocks

The SEC regulatory framework governing key aspects of short selling, including locate, close-out, and price-test provisions.

retained earningsStocks

Cumulative earnings retained in the company after dividends and other equity adjustments rather than distributed to shareholders. Full guide →

return on equityStocks

Net income divided by average shareholders equity, showing the profit generated per unit of owner capital. The DuPont decomposition splits it into net margin, asset turnover and financial leverage, which matters because borrowing alone can lift the ratio with no improvement in the underlying business. Buybacks that shrink the equity base also raise it mechanically.

return on assetsStocks

Net income divided by average total assets, measuring how much profit the asset base produces regardless of how it was financed. The figure is naturally low for asset-heavy industries such as utilities and high for asset-light software or services, so comparisons across sectors reveal more about business models than about management quality.

return on invested capitalStocks

After-tax operating profit divided by invested capital, where invested capital is borrowings plus equity less excess cash. It measures what the business earns on all the money put to work, independent of how that money was raised. Compared against the weighted average cost of capital, it indicates whether growth is creating or destroying value.

receivables turnoverStocks

Revenue or credit sales divided by average accounts receivable, measuring collection efficiency under a specified formula.

revenue growthStocks

The percentage increase in a company's sales over a prior period, used to gauge business momentum independent of profitability. Full guide →

retention ratioStocks

The share of profit a company keeps rather than distributing, equal to one minus the payout ratio. Multiplied by return on equity it produces the sustainable growth rate: the pace at which a business can expand using internal funds alone, without new borrowing or share issuance. A high reading only helps if the retained cash earns an adequate return.

reinvestment rateStocks

The proportion of after-tax operating profit a company puts back into the business through capital spending, acquisitions and working capital. In valuation models it multiplies with return on invested capital to produce the growth rate, formalizing the point that expansion has to be bought: growth requires capital, and its value depends on what that capital earns. Full guide →

revenue surpriseStocks

The difference between reported revenue and the pre-release consensus or specified revenue estimate.

risk-free rateStocksCrypto

A reference return intended to approximate an investment with minimal default risk over the relevant horizon, often proxied by government securities.

replacement costStocks

What it would cost today to rebuild an asset or an entire operating capability from scratch, including equipment, construction and the time required to bring it online. It sets a practical ceiling on what a rational buyer pays and a floor below which new competing supply is uneconomic. Tobin's q compares market value against this figure across an economy.

relative valuationStocks

Valuing an asset by comparing market multiples with peers, history, or benchmarks rather than estimating standalone discounted cash flows.

Rule of 40Stocks

A screening heuristic for software and subscription businesses that adds the revenue growth rate to a profitability margin, commonly free cash flow or operating margin, and asks whether the total reaches forty percent. It formalizes the tradeoff that faster expansion justifies thinner margins. The convention is an industry shorthand, not an accounting standard, and its inputs are defined inconsistently.

record dateStocks

The date an issuer uses to determine which holders of record are entitled to a dividend, vote, distribution, or other corporate action.

regular dividendStocks

A recurring cash distribution a company's board declares on a predictable schedule, commonly quarterly in the United States and semi-annually in many other markets. Because the market treats the level as an implicit commitment, boards typically set it at an amount they expect to sustain through a downturn, and reserve one-time special payments for surplus cash.

reverse splitStocks

A consolidation of existing shares that reduces the count and raises the quoted price proportionally, such as one new unit for every ten held. Total value is unchanged. It is most often used to lift a price back above an exchange's minimum listing requirement, and resulting fractional positions are typically cashed out rather than carried forward.

rights offeringStocks

An offering giving existing shareholders transferable or nontransferable rights to buy new shares, often in proportion to current holdings.

resistance zoneStocksCrypto

A price band where selling interest has repeatedly halted advances, drawn as an area because reversals cluster around prior highs and heavy-volume ranges rather than at one exact figure. Holders who bought higher and want to exit at breakeven are one source of the supply. A decisive break often converts the band into support. Full guide →

relative strengthStocksCrypto

The performance of one asset relative to another asset, benchmark, sector, or market over a defined period; it is distinct from RSI. Full guide →

relative weaknessStocksCrypto

Underperformance of an asset relative to a benchmark, peer group, or comparison asset over a specified period. Full guide →

realized volatility(RV) StocksCrypto

Volatility calculated from observed historical returns over a specified sampling frequency and lookback period. Full guide →

reward-to-riskStocksCrypto

The ratio of a trade's gain if the target is reached to the loss if the stop is hit, both measured from the entry price. A setup risking one unit to make three is quoted as three to one. The figure is only half the picture: expectancy also requires the probability of each outcome, and a high ratio usually comes with a lower hit rate. Full guide →

R-multipleStocksCrypto

A way to express a trade outcome relative to a pre-defined unit of planned risk. If 1R is the modeled planned loss, a +2R outcome is twice that unit. Realized losses can exceed -1R when gaps or execution are worse than the planned exit.

relative strength indexStocksCrypto

A momentum oscillator comparing the average size of recent gains against the average size of recent losses over a lookback, conventionally fourteen periods, mapped onto a zero to one hundred scale. Readings above seventy and below thirty are the traditional overbought and oversold markers, though in a strong trend the line can stay pinned at an extreme for a long stretch.

rate of changeStocksCrypto

A momentum indicator expressing the percentage difference between the current price and the price N periods earlier. It oscillates around zero, with the sign showing whether the market is above where it was and the slope showing whether that gap is widening. Because the lookback drops out abruptly, an old spike leaving the window shifts the reading without new price action.

relative volumeStocksCrypto

The ratio of the volume traded so far to what the instrument normally trades over the same portion of a session, usually measured against an average of recent days. A reading of two means twice the usual participation. It is used to distinguish a move backed by unusual activity from a drift occurring on ordinary turnover. Full guide →

rounding bottomStocksCrypto

A gradual reversal formation, sometimes called a saucer, in which a decline decelerates, price traces a shallow curved base over an extended period, and the advance accelerates on the far side. Volume usually falls toward the middle and rebuilds as price rises. Because the turn is slow there is no single dramatic confirmation point.

rounding topStocksCrypto

A gradual reversal formation in which an advance decelerates, price traces a shallow curved dome over an extended period, and the decline steepens on the far side. It reflects demand fading incrementally rather than a sharp change in sentiment. Volume often stays elevated near the peak and picks up again as price falls away from it.

rising wedgeStocksCrypto

A formation with both boundaries sloping upward but the upper one rising more slowly, so the range narrows as price advances. The loss of upward momentum inside a rising structure is why it is generally read as bearish, whether it appears within an uptrend or as a countertrend bounce. Confirmation is a close beneath the lower boundary.

rule-based tradingStocksCrypto

An approach in which entries, exits, position size and risk limits are specified in advance by explicit conditions rather than decided in the moment. Because the conditions are written down, the approach can be backtested, audited after the fact and executed by software. Its usefulness depends on whether the conditions were validated on data not used to create them.

range tradingStocksCrypto

Buying near the lower boundary of a sideways price band and selling near the upper boundary, treating those boundaries as areas where supply and demand have repeatedly reversed price. Stops sit just outside the band. The approach assumes mean reversion rather than continuation, so it performs poorly once the sideways structure resolves into a sustained directional move. Full guide →

relative strength strategyStocksCrypto

Ranking a universe of assets by performance against each other or against a benchmark, then holding the leaders and avoiding or shorting the laggards. Rankings are refreshed on a set schedule, which forces rotation as leadership changes. It differs from the RSI oscillator, which measures a single asset against its own recent history rather than comparing assets to one another.

risk toleranceStocksCrypto

The degree of variability in investment returns, including potential losses, that an investor is psychologically and emotionally willing and able to withstand without abandoning their strategy.

risk capacityStocksCrypto

The objective financial ability of an investor or organization to absorb losses without jeopardizing essential goals, based on factors like time horizon, income, liabilities, and liquidity needs rather than emotional comfort with risk.

risk appetiteStocksCrypto

The level and type of risk an investor or organization is willing to accept in pursuit of their objectives, reflecting a deliberate, forward-looking preference rather than an emotional reaction to losses.

risk managementStocksCrypto

The practice of identifying, measuring, and limiting the ways a portfolio can lose money, covering position size, exit placement, correlation between holdings, leverage, and maximum acceptable drawdown. It sets rules before capital is committed rather than reacting after a loss. Measurement tools include volatility estimates, value at risk, and stress tests against historical crisis periods. Full guide →

risk per tradeStocksCrypto

The amount of capital a trader accepts losing on a single position if the planned exit level is reached, usually expressed as a percentage of account equity. It links size to stop distance: quantity equals the accepted loss amount divided by the distance from entry to exit, per unit. Holding this figure constant keeps the impact of any one loss stable as the account changes size.

risk-reward ratioStocksCrypto

The ratio between a trade's potential loss (distance to the stop) and its potential gain (distance to the target), used alongside win rate to judge whether a strategy has positive expectancy.

risk of ruinStocksCrypto

The probability that losses deplete capital below a specified failure threshold before the strategy recovers, given assumptions about edge, variance, and sizing. Full guide →

recovery factorStocksCrypto

A performance ratio comparing cumulative or net profit with maximum drawdown; definitions vary across trading platforms.

risk parityStocksCrypto

A portfolio approach that allocates capital so assets or groups contribute more evenly to total portfolio risk rather than equalizing dollar weights. Full guide →

risk budgetingStocksCrypto

Allocating a portfolio by how much of its total volatility each position or sleeve is permitted to contribute, rather than by how much capital each receives. A turbulent holding therefore takes a smaller capital weight than a quiet one to consume the same share of the budget. Contributions account for correlation, so two holdings that move together use up more than their standalone volatilities suggest.

ratio spreadStocksOptions

An options position using unequal numbers of long and short contracts, which can create nonlinear and potentially undefined tail risk.

real GDPStocksCrypto

Economic output valued at the prices of a fixed base period, so measured growth reflects changes in the quantity of goods and services produced rather than changes in their prices. It is derived by deflating the current-price figure with a price index. Headline growth rates quoted for an economy are normally this inflation-adjusted series, reported at an annualized rate in the United States.

retail salesStocksCrypto

A monthly estimate of receipts at retail and food service businesses, used as a timely read on consumer spending, the largest component of output in many economies. The United States series is reported in current dollars and is not adjusted for inflation, so a rise can reflect higher prices as much as higher volume. A control group version strips autos, gasoline, building materials, and food services.

real interest rateStocksCrypto

An interest rate adjusted for inflation, approximately the stated rate minus expected inflation over the same horizon. It represents the change in purchasing power a lender earns or a borrower pays. Market-based estimates come from inflation-protected securities, where the gap against a comparable conventional bond gives the breakeven inflation rate. Negative values mean money lent loses purchasing power despite earning interest.

recovery phraseCrypto

An ordered list of common words, usually twelve or twenty-four, encoding the entropy from which a wallet derives all of its private keys. Anyone holding those words can regenerate the keys and move the funds using any compatible wallet software, which is why the list is kept offline and never entered into a website. It is also called a seed phrase or mnemonic.

retroactive airdropCrypto

A token distribution rewarding users for qualifying activity completed before the token or airdrop criteria were announced.

real yieldCrypto

Crypto shorthand for yield funded by external fees or economic revenue rather than primarily by newly issued incentive tokens; definitions vary and should state what cash flows are included.

reserve factorCrypto

The fraction of borrower interest retained by a lending protocol rather than paid to suppliers, often building protocol reserves.

receipt tokenCrypto

A token issued as evidence of a deposited, staked, lent, or locked position and often redeemable for the underlying claim.

restakingCrypto

Using already staked assets or staking-related tokens to provide economic security to additional protocols or services, creating additional reward and slashing dependencies.

reentrancy exploitCrypto

An attack where a contract calls out to an external address before updating its own internal accounting, letting the called contract call back in and repeat an action such as a withdrawal against stale balances. Repeated within one transaction, this can drain a pool. Standard defenses update state before making external calls and add a lock that blocks nested entry into the same function.

real-world assetCrypto

A claim on an off-chain asset such as a Treasury bill, a private credit loan, an invoice, a commodity, or property, tokenized so it can be held and transferred on a blockchain. The token's value depends on a legal structure plus a custodian or servicer enforcing the claim, so it carries counterparty and jurisdictional exposure that a purely on-chain instrument does not.

realized cap(realized capitalization) Crypto

An on-chain valuation metric that values each coin unit at the price when it last moved rather than at the current market price.

realized priceCrypto

Realized capitalization divided by circulating supply, often interpreted as an approximate aggregate on-chain cost-basis measure.

realized HODL wavesCrypto

A version of the age-band supply chart in which each band is weighted by realized value rather than by coin count, so the bands reflect the cost basis embedded in supply of each age instead of raw quantity. Recently acquired supply expands during periods of heavy buying at high prices. Analysts use the shift between young and old bands to describe wealth transfer across a market cycle.

realized profitCrypto

Profit inferred or recorded when coins are spent or positions are closed above their estimated cost basis.

realized lossCrypto

Loss inferred or recorded when coins are spent or positions are closed below their estimated cost basis.

revoke approvalCrypto

Setting a previously granted token spending allowance back to zero, so a contract can no longer move those tokens from the wallet. Allowances persist indefinitely once granted, including unlimited ones, so permission given to a contract that is later exploited remains exploitable. Block explorers and dedicated tools list outstanding allowances, and clearing one is itself an on-chain transaction that costs network fees.

rug pull(rug-pull) Crypto

A scam in which a project's creators abruptly withdraw liquidity, abandon development, or otherwise disappear with investor funds after building up hype or trust. Full guide →

recovery scamCrypto

Second-stage fraud that targets people who have already lost money, promising to trace or claw back stolen assets for an upfront fee. Operators find victims through public complaint threads or lists sold by the original fraudster, then present forged blockchain analysis, fake law-enforcement credentials, or a dashboard showing recovered balances that cannot be withdrawn until further payments clear. Blockchain transfers settle without a reversal mechanism, so no private service can unwind a confirmed transaction.

recordkeepingCrypto

Practice of retaining the transaction-level evidence needed to compute cost basis, holding period, and income as of the time each event occurred. For digital assets that means dates, quantities, fair market value in the reporting currency, fees, counterparties, wallet and exchange identifiers, and transaction hashes. Exchanges close, delist assets, and see only their own platform, so reconstructing a history later is often impossible, and the burden of substantiating a claimed basis sits with the taxpayer.

reserve attestationCrypto

A third-party examination or report addressing specified reserve balances at a point in time; its scope differs from a full financial-statement audit.

recency biasStocksCrypto

The tendency to overweight recent price action or news when forming expectations, at the expense of longer-term context.

revenge tradingStocksCrypto

Re-entering the market impulsively after a loss in an attempt to immediately win it back, typically with larger size or less discipline than the trader's normal process. Full guide →

regret aversionStocksCrypto

Tendency to make choices that minimize anticipated regret rather than maximize expected outcome. Because regret is felt more strongly for actions taken than for actions omitted, it biases toward inaction, toward conventional choices that are easier to justify afterward, and toward staying with the crowd. In portfolios it delays closing a losing position, since selling converts a paper loss into a definite one that has to be acknowledged.

rallyStocks

Sustained advance in price following a decline or a period of consolidation, driven by demand exceeding available supply at successive price levels. Rallies differ in what causes them: short covering, a change in earnings or macro expectations, or systematic buying can each produce one, and the source matters for whether the advance persists. The term carries no fixed magnitude or duration, describing direction and persistence rather than a defined threshold.

recall(sensitivity) StocksCrypto

In classification, the proportion of actual positive cases correctly identified by the model.

revenue(sales, top line) Stocks

The gross amount generated from selling goods or services before expenses are deducted.

R&DStocks

Research and development expense, the cost of investigating and creating new products, services, or processes. Under United States accounting rules most such spending is expensed as incurred rather than capitalized, so a company investing heavily reports lower current profit even though the outlay is intended to build long-lived value. Certain software development costs are treated differently. Tax rules on deducting or amortizing these costs are set by statute and have been changed several times.

ROEStocks

Return on equity, net income divided by average shareholders' equity, expressed as a percentage. It measures profit generated per unit of capital contributed and retained by owners. The DuPont decomposition splits it into net margin, asset turnover, and financial leverage, which shows that a high reading can come from operating efficiency or simply from balance sheet leverage. Buybacks shrink the denominator, so the ratio can rise while total profit is flat.

ROAStocks

Return on assets, net income divided by average total assets. It measures how much profit a business produces per unit of assets deployed, regardless of how those assets were financed. Because interest expense is deducted before net income while debt-funded assets remain in the denominator, some analysts add back after-tax interest to make numerator and denominator consistent. Typical levels differ sharply across industries, so the ratio compares meaningfully only within one.

ROICStocks

Return on invested capital, net operating profit after tax divided by invested capital, which is the debt and equity funding the operating business, usually net of excess cash. It measures the return earned on all capital regardless of source, so unlike return on equity it is not inflated by leverage. Comparing it with the weighted average cost of capital indicates whether growth adds or destroys value, since growth adds value only when the return exceeds the cost. Full guide →

roadshowStocks

Series of presentations in which a company's management and its underwriters meet institutional investors before an offering prices, to explain the business and gauge demand. The meetings feed the order book that determines final pricing and allocation. Communications during this period are constrained by securities rules, so materials are filed or access-restricted and management cannot present information beyond what the registration statement contains.

rangeStocksCrypto

A bounded price area defined by recurring support and resistance over a specified period.

resistanceStocksCrypto

Price area where supply has previously overcome demand and stopped an advance. It forms at prior swing highs, at levels where large volume traded and holders sit near break-even, at round numbers, and at widely followed averages. Like support it is a zone rather than a line, and its significance is judged by how many times price has turned there and on what volume. A decisive break through it often converts the area into support.

retestStocksCrypto

A return to a recently broken support, resistance, trendline, or range boundary to test whether the level now holds from the opposite side.

reversalStocksCryptoOptions

An arbitrage-style position using short stock, short put, and long call at the same strike and expiration to create a near-fixed payoff under parity assumptions.

RSIStocksCrypto

Relative strength index, a momentum oscillator bounded between zero and one hundred. It averages the gains and the losses across a lookback window, forms the ratio of average gain to average loss, and maps it through one hundred minus one hundred divided by one plus that ratio. Readings describe how one-sided recent price changes have been, and are conventionally read against upper and lower thresholds, with divergence between the oscillator and price also watched. Full guide →

ROCStocksCrypto

Rate of change, a momentum measure equal to the current price minus the price n periods ago, divided by that older price and multiplied by one hundred. It expresses the percentage move over a fixed lookback and oscillates around zero, positive when price is above where it was and negative when below. Because it compares only two points, its value can shift when the older reference bar rolls out of the window, independent of current price action.

RVOLStocksCrypto

Relative volume, the current interval's volume divided by the average volume for the same interval across a lookback of prior sessions. A reading above one means participation is heavier than normal for that time of day, which is used to judge whether a price move has unusual involvement behind it. Because it compares like periods, it corrects for the intraday volume curve, in which activity is typically heaviest near the open and the close.

riskStocks

Exposure to outcomes that differ from what was expected, including the possibility of permanent loss of capital. It is measured in several distinct ways, none of them complete: dispersion measures such as standard deviation and beta describe variability, downside measures such as drawdown, value at risk, and expected shortfall describe the loss tail, and scenario analysis describes behavior under specified conditions. Variability and the chance of missing an objective are related but separate ideas, and a measure built for one does not answer the other. Full guide →

rebalancingStocksCrypto

Trading positions to restore portfolio weights, risk exposures, or allocations toward predefined targets.

rhoStocksOptions

An option Greek estimating sensitivity to a change in interest rates, holding other model inputs constant.

rebateStocks

Payment a venue makes to a participant for supplying liquidity, the credit side of a maker-taker fee schedule in which the passive order is paid and the aggressive one charged. Rebates are quoted per share or per contract and set by the exchange within regulatory caps on access fees. The same word is used in securities lending, where the rebate rate is the portion of interest earned on cash collateral that is returned to the borrower.

recessionStocksCrypto

Significant decline in economic activity that is spread across the economy and lasts more than a few months, visible in output, employment, real income, and spending. In the United States the dates are set retrospectively by the National Bureau of Economic Research business cycle dating committee, which weighs depth, diffusion, and duration rather than applying the widely quoted rule of two consecutive quarters of falling GDP. Other countries use different conventions.

reflationStocks

Return of price growth and activity toward a normal level after a period of deflation or unusually weak demand, typically supported by monetary or fiscal easing. It describes a recovery phase rather than an overheating one, so it distinguishes rising prices that are closing an output gap from inflation that runs beyond it. In markets, a reflation trade generally means positioning for stronger nominal growth through cyclical sectors, commodities, and a steeper yield curve.

reorgCrypto

Reorganization, when nodes abandon one branch of a blockchain in favor of a competing branch that the consensus rule scores higher, so transactions confirmed in the discarded blocks return to the pending pool. Short reorgs of one or two blocks occur routinely from propagation delays. Deep ones are expensive to cause and would indicate either a large share of hash power or stake acting against the network, or a serious bug in widely used client software.

rollup(rollups) Crypto

Scaling systems that execute transactions off a base blockchain and post the resulting data plus evidence of correctness back to it, so the base layer supplies data availability and final settlement. Optimistic rollups assume the posted state is valid and open a challenge window in which anyone may submit a fraud proof. Validity rollups, often called zero-knowledge rollups, post a cryptographic proof that the state transition was correct. Distinct from a roll up in options trading, which moves a position to a higher strike.

reflexivityStocksCrypto

A feedback process where prices influence behavior, funding, collateral, narratives, and fundamentals, which then feed back into prices.

reentrancyCrypto

A smart-contract vulnerability where an external call allows control to return into a contract before prior state changes are safely completed.

RWACrypto

Real-world asset: an off-chain asset such as a Treasury bill, private credit loan, invoice, commodity, or property interest represented by a token on a blockchain. The token tracks a legal claim held by an issuer or trustee, so its value rests on that off-chain structure rather than on the chain itself. Redemption rights, custody arrangements, audits, and the governing legal jurisdiction determine whether the token is worth what it represents.

ransomwareCrypto

Malware that encrypts a victim's files or systems and demands payment, usually in cryptocurrency, for the decryption key. Many operators also steal data first and threaten publication, so paying does not remove the exposure. Payments are traceable on public blockchains, and sending funds to an entity or address subject to sanctions can itself breach the law in several jurisdictions regardless of the sender's intent or knowledge.

Relative Volume (RVOL)Stocks

A stock's current trading volume compared with its typical volume for the same period, used to flag unusual participation. Full guide →

RSI (Relative Strength Index)Crypto

A momentum oscillator, typically scaled 0-100, that measures the speed and size of recent price changes to identify potentially overbought or oversold conditions. Full guide →

RVOL False PositiveStocks

An elevated relative-volume reading caused by a distortion (a split, halt, block trade, or thin baseline), rather than genuine new interest in the stock. Full guide →

RVOL ScannerStocks

A screening tool that filters and ranks stocks in real time by relative volume alongside other criteria like price, float, and catalyst. Full guide →

Real Staking YieldCrypto

A staking-return concept that adjusts nominal token rewards for token issuance or inflation, attempting to measure growth in real economic ownership.

Reorganization(reorg) Crypto

A change to the recent canonical blockchain history when nodes adopt a competing chain branch under consensus rules.

A network address exposing node methods used to query blockchain data or submit transactions.

RPC ProviderCrypto

A service operating blockchain node infrastructure and providing application-accessible RPC endpoints.

Real-World Asset (RWA)(RWA) Crypto

A physical, financial, or legal-world asset whose ownership, claim, cash flow, or economic exposure is represented or serviced using blockchain technology.

Rebase AccountingCrypto

A yield-accounting method that changes token balances directly rather than changing the redemption value of each token.

Rebasing TokenCrypto

A token whose wallet balances automatically expand or contract according to protocol rules while proportional ownership may remain similar.

Redemption MechanismCrypto

The rules and infrastructure that let eligible holders exchange a token for underlying collateral, reserve assets, or another reference asset.

Reflection TokenCrypto

A token that redistributes a portion of transaction fees or other token flows among holders according to contract-defined rules.

Realized Cap HODL Waves(RHODL waves) Crypto

A variant of HODL waves weighted by realized capitalization rather than raw coin quantity.

Realized Price DistributionCrypto

A broader term for mapping token supply or cost basis across price levels using on-chain acquisition or last-moved estimates.

Realized Profit/Loss RatioCrypto

A comparison of aggregate realized profits with realized losses over a specified period.

Reserve RiskCrypto

A Bitcoin valuation metric relating price to a measure of long-term holder conviction based on coin-age behavior; it is model-dependent rather than intrinsic value.

Reverse Cash-and-CarryCrypto

Selling or shorting spot exposure while buying discounted futures to profit if the basis converges, subject to borrow and execution constraints.

RFQCrypto

Request for quote: a workflow where a trader asks one or more liquidity providers for executable prices on a specified instrument or multi-leg package.

RHODL RatioCrypto

Rate-Limit BanCrypto

A temporary API restriction triggered when a client exceeds allowed request limits or abuse controls.

Read-Only API KeyCrypto

An API credential limited to retrieving account or market information without permission to trade or withdraw.

Read-Only ReentrancyCrypto

A vulnerability where a view or pricing function observes inconsistent intermediate state during an external call even if direct state-changing reentrancy is blocked.

Recovery ThresholdCrypto

The minimum number of guardian approvals or key shares required to restore a wallet or authorize a recovery action.

Reentrancy GuardCrypto

A contract pattern or mechanism that prevents sensitive functions from being re-entered during the same call stack.

Reflexive TokenomicsCrypto

Token mechanics where price appreciation increases collateral, incentives, treasury value, or adoption in ways that can reinforce demand, with the reverse possible during declines.

Rekt(wrecked) Crypto

Crypto slang meaning a trader or position suffered a severe loss or liquidation.

Renounced OwnershipCrypto

A contract state where the designated owner role has been removed or transferred to an unusable address; this does not prove the contract is safe or immutable.

Replay AttackCrypto

Rebroadcasting a valid transaction or signed message on another chain or context where it remains valid, potentially causing unintended duplicate actions.

Replay ProtectionCrypto

Protocol or transaction rules that prevent signatures intended for one chain or context from being reused on another.

Responsible DisclosureCrypto

Privately reporting a vulnerability to maintainers and giving them a reasonable opportunity to fix it before public disclosure.

REST APICrypto

A request-response web interface commonly used by exchanges for orders, balances, historical data, and configuration.

Retroactive Public Goods Funding(RPGF) Crypto

A model that rewards projects after they have created measurable ecosystem or public value rather than funding them entirely in advance.

Ring SignatureCrypto

A cryptographic signature proving that one member of a group signed a message without revealing which member.

RingCT(Ring Confidential Transactions) Crypto

Ring Confidential Transactions: a privacy construction used in Monero to hide transaction amounts while combining ring-based sender ambiguity.

A combination of a long option on one side and a short option on the opposite side, often used to create directional exposure or measure volatility skew.

Risk-Neutral DensityStocksOptions

A probability density implied from option prices under risk-neutral pricing assumptions, often extracted from the shape of the option surface.

Risk-Neutral Probability(Risk-Neutral Probabilities) StocksOptions

Risk-neutral probabilities are the weights used in derivative pricing under which the expected return on every asset equals the risk-free rate, so that discounting an expected payoff at that rate produces the arbitrage-free value. They are not forecasts of how likely outcomes actually are: they embed the market's aversion to risk, which is why the implied chance of a large decline exceeds what historical frequencies suggest. Their existence follows from the absence of arbitrage, and their uniqueness follows from market completeness.

Roll DownStocksOptions

Moving an options position to a lower strike by closing the existing contract and opening a lower-strike replacement.

Roll Down and OutStocksOptions

Moving an options position to both a lower strike and later expiration.

Roll OutStocksOptions

Moving an options position to a later expiration while keeping the strike the same or similar.

Roll Up and OutStocksOptions

Moving an options position to both a higher strike and later expiration.

Rolling an Option(roll) StocksOptions

Closing an existing option and opening another with a different strike, expiration, or both, usually in a coordinated order.

A partial reversal of a prior price move, commonly measured as a percentage of that move.

Roth IRAStocks

An individual retirement account funded with after-tax contributions, where qualified withdrawals of both contributions and investment growth are tax-free in retirement. Contributions can generally be withdrawn at any time without tax or penalty, but earnings withdrawn early may trigger taxes and penalties. Eligibility to contribute directly phases out above certain income levels, and the account is not subject to required minimum distributions during the original owner's lifetime. Full guide →

REIT (Real Estate Investment Trust)(real estate investment trust) Stocks

A REIT (real estate investment trust) is a company that owns, operates, or finances income-producing real estate and is required by law to distribute at least 90% of its taxable income to shareholders as dividends in exchange for favorable corporate tax treatment. REITs trade on stock exchanges like ordinary shares, giving investors access to diversified real estate exposure (such as apartments, offices, warehouses, or mortgages) without directly buying or managing property. Because of their high mandated payout, REITs are often held for income, and their dividends are frequently taxed as ordinary income rather than at qualified dividend rates.

Real Estate InvestingStocks

Real estate investing is the practice of purchasing, owning, financing, or managing property with the goal of generating income, appreciation, or both. Investors can gain exposure directly, by buying physical residential or commercial property, or indirectly through vehicles such as REITs, real estate crowdfunding platforms, or real estate mutual funds and ETFs, each offering different tradeoffs in liquidity, minimum investment, and management involvement. Common return drivers include rental income, property appreciation, and tax benefits such as depreciation, while risks include vacancy, illiquidity, leverage, and local market cycles.

Rental YieldStocks

Rental yield measures the annual rental income a property generates as a percentage of its value, expressed either as a gross yield (using rental income before expenses) or a net yield (using income after operating costs such as taxes, insurance, and maintenance, but before financing costs). It is used to compare the income-generating potential of different rental properties independent of price appreciation. Rental yield is closely related to cap rate but is sometimes calculated against purchase price rather than current market value, so the two figures can diverge over time.

Random AssignmentOptions

The OCC's method for allocating exercise notices to clearing member firms: rather than assigning in the order positions were opened, the OCC selects which member firms are assigned using a randomized, lottery-style procedure among all firms carrying short positions in that option series. Full guide →

recession probability modelStocksCrypto

A statistical or econometric model (such as those built from the yield curve slope, the Sahm rule, or a composite of leading indicators) that converts current economic data into an estimated probability that the economy is in or entering a recession within a given time horizon; used by traders and economists to quantify recession risk rather than rely on a single binary signal. Full guide →

Reverse Stress TestStocksOptionsFuturesCrypto

A risk assessment that starts from a predefined severe outcome, such as portfolio failure or a specified loss threshold, and works backward to identify the combination of scenarios that could cause it. Full guide →

Roll YieldFutures

The gain or loss generated when a futures position is closed in an expiring contract and reopened in a later-dated one, driven by the price difference between the two contracts; positive in backwardated markets and negative in contango. Full guide →

Round TurnFutures

A completed futures trade consisting of both the opening and closing transaction in a contract, the unit on which most futures commission rates are quoted (a single commission covers the full buy-and-sell or sell-and-buy cycle).

Regulation ATSStocks

The SEC framework (Exchange Act Rules 300-303) that lets an alternative trading system operate without registering as a national securities exchange, provided it registers as a broker-dealer, files Form ATS, and meets fair-access and other conditions once its volume crosses set thresholds.

Rule 605(SEC Rule 605, Order Execution Quality Report) StocksOptions

The SEC rule requiring market centers that execute NMS stock and option orders, and large introducing broker-dealers, to publish monthly, standardized statistics on execution quality such as fill rates, speed, and price improvement. Full guide →

Rule 606(SEC Rule 606, Order Routing Disclosure) StocksOptions

The SEC rule requiring broker-dealers to publish quarterly reports disclosing where they routed customers' non-directed equity and options orders and describing any payment or other relationship with those venues. Full guide →

Retail Liquidity Program(RLP) Stocks

Retail Price Improvement(RPI, RPI order) Stocks

A non-displayed order type used within a retail liquidity program that offers retail customer orders execution at a price better than the prevailing best bid or offer, typically in sub-penny increments. Full guide →

Request for Quote(RFQ) StocksOptionsCrypto

A trading protocol in which a participant asks one or more liquidity providers to submit a price for a specific size and instrument on demand, rather than trading against continuously displayed quotes.

Redemption Fee(early redemption fee) Stocks

A short-term charge some mutual funds impose on shares sold within a set holding period, typically 30 to 90 days after purchase, intended to discourage rapid in-and-out trading that raises costs for remaining shareholders.

Representative Sampling(optimized sampling) Stocks

An index-tracking method in which a fund holds a subset of an index's constituents, chosen and weighted to statistically match the index's risk and return characteristics, rather than owning every single security.

Rollover IRAStocks

A Traditional IRA opened specifically to receive assets moved from an employer retirement plan, such as a 401(k), typically after a job change or retirement. Rolling funds into an IRA preserves their tax-deferred status and often widens investment choice beyond what the former employer's plan offered, as long as the transfer is completed correctly and within any applicable time window. Full guide →

Required Minimum Distribution(RMD) Stocks

The minimum amount the IRS requires an account owner to withdraw each year from most tax-deferred retirement accounts once they reach a specified age, calculated by dividing the prior year-end account balance by an IRS life-expectancy factor. Roth IRAs are exempt from RMDs during the original owner's lifetime, and missing an RMD triggers an excise tax penalty on the shortfall. Full guide →

Russell 2000Stocks

A float-adjusted, market-capitalization-weighted index of roughly 2,000 U.S. small-cap companies, made up of the smallest members of the broader Russell 3000 Index. Maintained by FTSE Russell and reconstituted annually, it is the primary benchmark used to measure U.S. small-cap stock performance. Full guide →

Rectangle Pattern(Trading Range, Box Pattern) StocksCrypto

A continuation pattern where price oscillates between two roughly horizontal, parallel support and resistance lines for an extended period before eventually breaking out in the direction of the prior trend.

Runaway Gap(Measuring Gap) StocksCrypto

A gap that appears in the middle of an established trend on continued strong volume, signaling the trend is accelerating; because it often occurs roughly halfway through the move, traders use it to estimate a remaining price target.

Relative Vigor Index(RVI) StocksCrypto

A momentum oscillator that measures the strength of a trend by comparing an asset's closing price to its trading range, based on the idea that prices tend to close higher than they open in strong uptrends and lower in strong downtrends.

rebase tokenCrypto

A token whose total supply automatically expands or contracts at set intervals, adjusting every holder's wallet balance proportionally, so the token's price is meant to track a target rather than the individual holder's share of supply.

recovery modeCryptoDeFi

A protocol-wide safety state some lending or CDP protocols trigger when the system's overall collateralization ratio falls below a set threshold, temporarily tightening liquidation rules on the riskiest positions to protect the system's solvency. Full guide →

reentrancy attackCryptoDeFi

A smart-contract exploit where a malicious contract repeatedly calls back into a vulnerable function before its first execution finishes updating state, draining funds by triggering the same withdrawal or transfer logic multiple times within one transaction. Full guide →

Rule 72(t) (SEPP)(72(t), Substantially Equal Periodic Payments, SEPP) Stocks

An exception to the 10% early-withdrawal penalty on retirement account distributions taken before age 59½, available when the account owner commits to a fixed schedule of substantially equal periodic payments, calculated under one of the IRS-approved methods and continued for at least five years or until age 59½, whichever is later. Full guide →

Residential Real EstateStocks

Residential real estate is property designed for people to live in, including single-family homes, condominiums, townhomes, and small multifamily buildings of up to four units, as distinct from commercial or industrial property. Investors buy it for rental income, appreciation, or resale, typically using conventional or government-backed residential mortgages rather than commercial loans. It is the most widely held real estate asset class among individual investors because of smaller capital requirements and broad financing availability.

Rental PropertyStocks

A rental property is any real property purchased with the intent of generating income by leasing it to tenants, spanning single-family homes, multifamily buildings, and commercial space. Returns combine periodic cash flow (rent minus operating expenses and debt service) with potential price appreciation, and owners in the U.S. can generally deduct mortgage interest, depreciation, and operating expenses against rental income for tax purposes.

REIT(REITs) Stocks

REIT is the abbreviation for real estate investment trust, a company that owns, operates, or finances income-producing real estate and, under U.S. tax rules, must distribute at least 90% of its taxable income to shareholders as dividends in exchange for avoiding corporate-level income tax. REITs let investors gain real estate exposure and income through publicly traded shares without directly owning or managing property. Equity REITs own buildings and collect rent, while mortgage REITs hold property debt and earn a spread. Because depreciation depresses reported earnings, analysts use funds from operations, and the required payout means growth is funded by issuing new shares or debt. Full guide →

REIT ETFStocks

A REIT ETF is an exchange-traded fund that holds a basket of publicly traded REITs, giving investors diversified real estate exposure across property sectors and companies through a single, exchange-listed security. REIT ETFs trade throughout the day like stocks and typically track an index such as the FTSE Nareit All Equity REITs Index, offering more diversification and liquidity than owning individual REIT shares.

Real Estate SyndicationStocks

Real estate syndication pools capital from multiple passive investors, led by a sponsor (or general partner) who identifies, acquires, and manages the property, to buy real estate too large for one investor to purchase alone. Investors (limited partners) typically receive passive income and a share of appreciation in exchange for a portion of profits paid to the sponsor, and syndications are usually structured as private placements available only to accredited investors under SEC exemptions such as Regulation D.

Rental Property CalculatorStocks

A rental property calculator is a tool that estimates a rental property's expected cash flow, cap rate, cash-on-cash return, and other key metrics from user inputs such as purchase price, rent, financing terms, and operating expenses, letting investors quickly compare potential deals before committing to deeper underwriting.

Rental ROI CalculatorStocks

A rental ROI calculator estimates a rental property's return on investment by comparing annual profit (cash flow plus, in some versions, principal paydown and appreciation) to the cash actually invested, most commonly expressed as cash-on-cash return, letting investors compare deals on a standardized percentage basis.

REIT Comparison ToolsStocks

REIT comparison tools are screeners and dashboards that let investors evaluate REITs side by side on metrics such as dividend yield, price-to-FFO, AFFO payout ratio, property sector, and total return, helping narrow a large universe of publicly traded REITs down to candidates that fit an investor's income or growth goals.

Raw Land(vacant land) Stocks

Raw land is undeveloped property with no structures, utilities, or site improvements, distinguishing it from land that has been graded, permitted, or connected to utilities in preparation for construction. Because it generates no rental income and cannot be depreciated, raw land investors rely on appreciation, rezoning, or eventual development for returns, and lenders typically require larger down payments and charge higher rates for raw-land loans than for improved property.

Recreational LandStocks

Recreational land is a parcel purchased primarily for hunting, fishing, camping, off-road use, or other leisure activities rather than farming or development, and its value is driven by features like wildlife habitat, water frontage, timber, and access rather than income potential. It can occasionally generate income through hunting leases, but most owners hold it for personal use and long-term appreciation rather than cash flow.

Royalty InvestmentStocks

A royalty investment is the purchase of a right to future royalty payments generated by an underlying asset, such as a mineral deposit, oil or gas well, patent, or piece of music, in exchange for an upfront sum, giving the buyer ongoing income without operating the underlying asset itself. Royalty income is generally uncorrelated with stock and bond markets since it depends on the asset's specific production or licensing activity, but it is illiquid and its value depends on accurately forecasting the future output or usage the royalty is based on.

Royalty(royalties) Stocks

A royalty is a payment made by one party to another for the ongoing right to use an asset, most commonly intellectual property (patents, trademarks, copyrights) or natural resources (minerals, oil and gas), typically calculated as a percentage of sales, revenue, or production volume. Royalties let asset owners earn recurring income from a third party's use of the asset without operating the underlying business, mine, or well themselves.

Royalty StreamStocks

A royalty stream is the ongoing series of periodic royalty payments generated by a licensed or royalty-bearing asset over time, which investors can buy, sell, or use as collateral much like a bond's cash flow stream. Unlike a fixed-coupon bond, a royalty stream's size and timing typically vary with the underlying asset's sales, production, or usage, making it a variable, market- or production-linked income source rather than a fixed one.

Royalty CompanyStocks

A specialty finance company that provides capital to mining companies in exchange for a small percentage (typically 1%-3%) of revenue or production from a mine, for the life of that property, without operating the mine or bearing most of its capital costs. Royalty companies such as Franco-Nevada and Royal Gold hold diversified portfolios of royalties across many mines, which lowers single-asset risk relative to owning one mining stock.

Rare CoinsStocks

Coins whose value derives substantially from scarcity, historical importance, minting errors, or exceptional condition rather than metal content: a subset of the broader numismatic coin category. Prices are set by specialist dealers and auction houses and depend heavily on third-party grading from services such as PCGS or NGC.

Rare WhiskeyStocks

Whiskey bottles distinguished by extreme age, closed-distillery origin, tiny production runs, or historic significance, commanding prices far above standard collectible whiskey. Because whiskey doesn't change once bottled, a rare bottle's value rests on scarcity, brand prestige, and collector demand rather than any further maturation.

RefineryStocks

An industrial facility that processes crude oil into refined products such as gasoline, diesel, jet fuel, and heating oil through distillation and chemical processing. Refinery profitability is measured by the "crack spread" (the margin between crude oil input costs and the prices of the refined products produced), which can move independently of, and sometimes opposite to, crude oil prices themselves.

Royalty TrustStocks

A publicly traded trust that holds a fixed royalty interest in a specific pool of producing oil and gas (or mineral) properties and distributes the resulting income to unitholders, without conducting any operations itself. Because the underlying reserves are a fixed, depleting asset with no ability to acquire new properties, distributions typically decline over time and the trust is dissolved once reserves are exhausted or production falls below a set threshold.

Renewable Energy(clean energy) Stocks

Energy generated from naturally replenishing sources (solar, wind, hydroelectric, and geothermal power) as an investment theme spanning utility developers, equipment manufacturers, and dedicated funds. Renewable energy investing carries distinct drivers from fossil-fuel energy investing, including government subsidies and tax credits, interest-rate sensitivity (given capital-intensive project financing), and technology cost curves.

Roth 401(k)Stocks

An employer-sponsored retirement plan funded with after-tax salary deferrals, so qualified withdrawals of contributions and earnings in retirement are federal-income-tax-free. Since a SECURE 2.0 Act change effective 2024, Roth 401(k)s are no longer subject to required minimum distributions during the original owner's lifetime, matching Roth IRA treatment, but a non-qualified early withdrawal is taxed pro-rata between contributions and earnings rather than contributions-first as with a Roth IRA.

Roth conversionStocks

The act of moving funds from a traditional, pre-tax IRA or employer plan into a Roth IRA, paying ordinary income tax on the converted pre-tax amount in the year of conversion in exchange for future tax-free qualified withdrawals. There is no income limit or annual cap on how much can be converted, which is why Roth conversions are the mechanism behind the backdoor Roth strategy for high earners otherwise ineligible to contribute directly to a Roth IRA. Full guide →

rollover windowStocks

The 60-day period an individual has to redeposit funds from an indirect rollover into another eligible retirement account to avoid the distribution being taxed as ordinary income and, if applicable, penalized. Missing the rollover window generally converts the withdrawal into a permanent taxable distribution, though the IRS allows a self-certification procedure for a limited set of qualifying hardship reasons for late rollovers.

recharacterizationStocks

The IRS-permitted process of treating an IRA contribution as if it had originally been made to a different type of IRA, effectively undoing the original classification before the tax-filing deadline. The Tax Cuts and Jobs Act eliminated the ability to recharacterize Roth conversions back to traditional starting in 2018, so recharacterization today applies only to original contributions, not conversions.

Roth IRA five-year ruleStocks

The requirement that a Roth IRA must have been open for at least five tax years, starting January 1 of the year of the first contribution to any Roth IRA the person owns, before earnings can be withdrawn tax-free, even after the owner reaches age 59½. Because the clock is based on the first Roth IRA ever opened rather than each individual account, opening a Roth IRA early, even with a small contribution, can start this clock years before it's actually needed.

required beginning date(RBD) Stocks

The date by which an account owner must take their first required minimum distribution from a tax-deferred retirement account, generally April 1 of the year following the year they reach the RMD starting age set by current law, which SECURE 2.0 raised to 73 for most people and is scheduled to rise to 75 in 2033. Delaying the first RMD to this date means two distributions may be due in the same calendar year, which can push the owner into a higher tax bracket.

relationship to other account typesStocks

A general concept describing which retirement, education, and health accounts can be rolled over, converted, or transferred into one another under IRS rules: for example, a traditional 401(k) can roll into a traditional IRA or another employer plan, a Roth 401(k) can roll into a Roth IRA, and a 529 plan can, subject to strict conditions, roll into a Roth IRA, but pre-tax and Roth money generally cannot be combined without triggering taxation. Understanding these compatibility rules matters when consolidating accounts after a job change or coordinating a multi-account tax strategy like the backdoor or mega backdoor Roth.

riderStocks

An optional add-on provision attached to an annuity or life insurance contract that modifies or enhances the base policy's benefits, such as guaranteeing a minimum income, adding long-term-care coverage, or accelerating a death benefit, in exchange for an additional annual fee. Riders are elected at or after purchase and vary widely between insurers, so their guarantees and costs must be evaluated individually rather than assumed to be standard.

revocable trustStocks

A trust the grantor can amend, modify, or dissolve at any time during their lifetime, most commonly used as a living trust to avoid probate while retaining full control over the assets. Because the grantor retains this control, assets in a revocable trust are still considered part of the grantor's estate for tax purposes and remain reachable by the grantor's creditors, unlike assets placed in most irrevocable trusts.

revenue bondStocks

A revenue bond is a municipal bond repaid solely from the income generated by the specific project it finances, such as toll roads, airports, water utilities, or stadiums, rather than from general tax revenue. Because repayment depends on a single revenue stream, revenue bonds are generally considered riskier than general obligation bonds and typically offer higher yields to compensate. Revenue bond covenants often include debt service coverage requirements and other protections that limit how much revenue can be used for purposes other than paying bondholders.

reinvestment riskStocks

Reinvestment risk is the risk that coupon payments or bond principal returned early (through a call or maturity) must be reinvested at a lower prevailing interest rate than the original bond earned. It is most significant for callable bonds, which tend to be redeemed precisely when rates have fallen, and for shorter-maturity bonds and CDs that mature and need to be rolled over more frequently. Reinvestment risk works in the opposite direction of interest-rate risk: falling rates hurt future reinvestment income even as they raise the current market price of existing bonds. Full guide →

reverse convertible(reverse convertible note) StocksOptions

A reverse convertible is a short-term structured note that pays a high fixed coupon in exchange for the investor accepting downside risk in an underlying reference stock or index. If the underlying stays above a specified barrier level through maturity, the investor receives full principal back plus the coupon; if the underlying falls below the barrier, the investor instead receives a predetermined number of the underlying shares (or an equivalent cash value) worth less than the original investment, absorbing the loss. The high coupon compensates for effectively having sold a put option on the underlying, and losses can significantly exceed the coupon received if the underlying falls sharply.

REIT distributionsStocks

REIT distributions are the periodic cash payments a real estate investment trust makes to shareholders, required by law since REITs must distribute at least 90% of their taxable income annually to maintain their special tax status. Unlike most corporate dividends, the bulk of a REIT distribution is typically classified as ordinary income rather than qualified dividends, so it does not receive preferential capital-gains tax rates, though a portion may qualify for the Section 199A qualified business income deduction, and part may be treated as a nontaxable return of capital that reduces cost basis instead. Because of this ordinary-income tax treatment, REIT shares are often considered better suited to tax-advantaged accounts than a fully taxable brokerage account.

royalty incomeStocks

Royalty income is payment received for the right to use an owned asset, such as intellectual property, a patent, a franchise, or mineral and oil/gas rights, typically calculated as a percentage of revenue or per-unit production generated by the asset's use. Investors can gain exposure to royalty income indirectly through royalty trusts and certain specialty funds, which pass through income from underlying royalty interests, often with variable payouts tied to commodity prices or production volumes. Royalty income is generally taxed as ordinary income, and royalty trust units carry unique tax reporting considerations, including depletion allowances, that differ from typical dividend-paying stocks.

rental incomeStocks

Rental income is money received from leasing real property to tenants, whether from direct real estate ownership or indirectly through investments like real estate crowdfunding platforms. For tax purposes, rental income is generally reported on Schedule E and can be reduced by deductible expenses such as mortgage interest, property taxes, insurance, maintenance, and depreciation, which often makes a rental property's taxable income lower than its actual cash flow. The IRS treats rental activity as passive income for most investors who do not materially participate in managing the property, with specific rules limiting how passive losses can offset other income.

RVPI(residual value to paid-in capital) Stocks

A private fund performance metric that measures the estimated current value of a fund's remaining, unrealized investments relative to capital paid in by limited partners. RVPI represents the unrealized portion of TVPI and declines toward zero as a fund matures and exits its holdings.

Regulation Crowdfunding(Reg CF, Regulation CF) Stocks

The SEC exemption, adopted under Title III of the 2012 JOBS Act, that allows companies to raise up to $5 million in a 12-month period from both accredited and non-accredited investors through a registered online funding portal or broker-dealer. Regulation Crowdfunding imposes investment limits on non-accredited investors tied to their income or net worth, and requires issuers to make specified financial disclosures.

Reg CF(Regulation Crowdfunding) Stocks

The common shorthand for Regulation Crowdfunding: the SEC exemption letting private companies raise up to $5 million in a rolling 12-month period from the general public, including non-accredited investors, through a registered funding portal.

Regulation A(Reg A) Stocks

An SEC exemption, sometimes called a 'mini-IPO,' that allows private companies to raise capital from the public with lighter disclosure requirements than a full registered offering. Regulation A has two tiers: Tier 1 permits raises up to $20 million and Tier 2 permits raises up to $75 million in a 12-month period, with Tier 2 issuers subject to ongoing SEC reporting but exempt from state-by-state registration.

Reg A+(Regulation A+) Stocks

The common name for the modernized Regulation A framework created by the 2012 JOBS Act, which expanded the older Regulation A exemption and added a Tier 2 option allowing raises of up to $75 million in a 12-month period, open to both accredited and non-accredited investors. Non-accredited investors in Tier 2 offerings are generally subject to investment limits based on their income or net worth.

Regulation D(Reg D) Stocks

An SEC exemption from full registration requirements that lets companies raise private capital without a public offering, most commonly used for venture capital and private equity fundraising. Regulation D offerings are typically conducted under Rule 506(b) or Rule 506(c), both of which allow unlimited fundraising from accredited investors but differ in whether general solicitation is permitted.

Rule 506(b)(506(b)) Stocks

A Regulation D safe harbor allowing companies to raise unlimited capital from an unlimited number of accredited investors plus up to 35 sophisticated non-accredited investors, without registering the offering with the SEC. Rule 506(b) prohibits general solicitation or public advertising of the offering, requiring issuers to rely on pre-existing relationships with investors.

Rule 506(c)(506(c)) Stocks

A Regulation D safe harbor, added by the 2012 JOBS Act, that permits companies to raise unlimited capital and to publicly advertise or generally solicit the offering, but restricts participation to accredited investors only. Unlike Rule 506(b), issuers relying on Rule 506(c) must take reasonable steps to verify each investor's accredited status rather than relying on self-certification.

relative value(relative value strategy) Stocks

A hedge fund strategy that seeks to profit from pricing discrepancies between related securities (such as two bonds of similar credit quality or a convertible bond versus the issuer's equity), rather than betting on the direction of the overall market. Relative value strategies typically hold offsetting long and short positions designed to isolate the pricing gap while hedging broader market risk.

redemption gate(gate) Stocks

A contractual limit in a hedge fund's governing documents that caps the percentage of fund assets, or the percentage of an individual investor's holdings, that can be withdrawn in a given redemption period. Redemption gates are used to prevent a rush of withdrawals from forcing a fund to sell illiquid positions at fire-sale prices, but they also mean investors cannot always access their capital on demand.

recovery rateStocks

The percentage of a defaulted loan's principal that a lender ultimately recovers, through collections, collateral liquidation, or a bankruptcy proceeding. Recovery rate, combined with the default rate, determines an investor's realized loss on a defaulted loan or debt security.

retail investorStocks

An individual, non-professional investor who buys and sells securities for their own personal account rather than on behalf of an organization. Retail investors generally have full access to public markets but face restrictions on private offerings unless they separately qualify as accredited or sophisticated investors.

redemption(SPAC redemption) Stocks

The right of a SPAC's public shareholders to return their shares for a pro-rata portion of the cash held in trust, rather than participate in the proposed merger, typically exercised around the shareholder vote on a business combination. High redemption rates can leave a merged company with far less cash than originally anticipated, sometimes forcing it to raise additional financing (PIPE funding) to close the deal.

real estateStocks

Land and improvements to it (residential, commercial, or industrial property) held as an alternative investment for income, appreciation, or both, either directly or through vehicles like real estate investment trusts (REITs) and private real estate funds. As an alternative asset class, real estate is valued for cash flow, potential inflation-hedging characteristics, and historically imperfect correlation with public stock and bond markets.

Registered Investment Adviser (RIA)(RIA) Stocks

An investment advisory firm that has formally registered with the SEC or a state securities regulator under the Investment Advisers Act of 1940, subjecting it to fiduciary duty, disclosure, and examination requirements. RIA status is a regulatory designation for the firm, distinct from professional credentials like the CFP that an individual advisor working at the firm might hold.

Robo-Advisor(robo advisor) Stocks

A digital investment platform that builds and manages a portfolio automatically based on an investor's stated goals and risk tolerance, using algorithms to select funds, allocate assets, and rebalance over time with minimal human involvement. Robo-advisors typically charge lower advisory fees than traditional human advisors and often layer in automated features like tax-loss harvesting, but usually offer more limited holistic financial planning.

Risk Questionnaire(risk tolerance questionnaire) Stocks

A structured set of questions a robo-advisor or human advisor uses to gauge a client's risk tolerance, time horizon, and financial goals, translating the answers into a recommended asset allocation. Risk questionnaires measure both an investor's willingness to take risk (psychological comfort with losses) and capacity for risk (financial ability to withstand losses), which can point to different conclusions if not both considered.

Retirement Date (Target-Date Fund)(target retirement date) Stocks

The year identified in a target-date fund's name (e.g., a '2050 Fund') that anchors its glide path, representing the approximate year an investor in that fund expects to retire or begin withdrawing assets. Investors typically choose a fund by matching this year to their own expected retirement year, but it functions purely as a scheduling input for the fund's asset-allocation formula: it does not guarantee any specific outcome or that the fund's risk level will suit every investor targeting that year.

Return(Investment Return) Stocks

Return is the gain or loss on an investment over a given period, expressed as a percentage of the amount originally invested, combining both price appreciation and any income received such as dividends or interest. It is the fundamental measure used to evaluate and compare investment performance.

Real Return(Inflation-Adjusted Return) Stocks

Real return is an investment's return after subtracting the effect of inflation, showing the actual change in an investor's purchasing power over a period. It gives a more accurate picture of investment performance than nominal return, particularly over long horizons or during periods of elevated inflation.

Redemption Period(Redemption Window, Lock-Up Period) Stocks

A redemption period is the specific window of time during which investors are permitted to withdraw money from a fund, such as a hedge fund, private fund, or non-traded REIT, often subject to advance notice requirements. Funds with restrictive redemption periods (sometimes preceded by an initial lock-up period during which no withdrawals are allowed at all) trade investor liquidity for the ability to hold longer-term, less liquid underlying assets.

REIT NAV(net asset value (REIT)) Stocks

REIT NAV (net asset value) is an analyst's estimate of a REIT's underlying real-estate portfolio value, derived by applying market capitalization rates to the REIT's net operating income (or using appraisals) and then subtracting debt and other liabilities. Unlike a mutual fund's formulaic, daily-calculated NAV, REIT NAV is an estimate that varies by analyst and methodology, and a REIT's traded share price can sit at a premium or discount to that estimated NAV.

Retirement Account(retirement account types, tax-advantaged retirement account) Stocks

A retirement account is any of several tax-advantaged account structures, such as an employer-sponsored 401(k) or an individual IRA, designed to hold investments earmarked for retirement in exchange for tax benefits on contributions, growth, or withdrawals. Which specific rules apply, contribution limits, withdrawal timing, and required distributions, depend on the account type and are set by the IRS. Full guide →

RRSP(Registered Retirement Savings Plan) Stocks

A Registered Retirement Savings Plan (RRSP) is a Canadian tax-advantaged personal retirement account. Contributions are deducted from taxable income in the year they are made, investments grow tax-deferred inside the account, and withdrawals are taxed as ordinary income when eventually taken out, typically in retirement. Contribution room is based on earned income and is regulated by the Canada Revenue Agency (CRA).

Ratio AnalysisStocks

Ratio analysis studies a company by dividing one financial statement figure by another so that firms of different sizes become comparable. The families are liquidity (current and quick ratios), leverage (debt to equity, interest coverage), profitability (gross and operating margin, return on equity), efficiency (inventory and receivable turnover) and valuation (price to earnings, enterprise value to EBITDA). A single ratio says little on its own. The information comes from comparing it against the same company over several years and against direct competitors reporting under the same accounting standards.

Realization MultipleStocks

The realization multiple measures how much cash a private fund has actually returned to its limited partners relative to what they paid in. It equals cumulative distributions divided by paid-in capital, so a value of one means investors have been made whole in nominal terms and anything above one is realized gain. Because it counts only money that has left the fund, it is harder to flatter than a valuation-based multiple, though it ignores timing and therefore says nothing about the annualized rate of return.

Reserve CurrencyStocksFutures

A reserve currency is one that central banks and finance ministries hold in quantity as foreign exchange reserves and that private parties widely use to invoice trade, borrow and settle cross-border payments. Reserve status rests on deep and liquid government debt markets, open capital accounts, predictable legal treatment of foreign holders and a long record of convertibility. The issuing country gains cheaper funding and can run larger external deficits, but it also imports demand for its assets that can complicate domestic monetary policy.

RevolverStocks

A revolver is a committed credit line the borrower may draw, repay and draw again up to an agreed limit for the life of the facility. Pricing has two parts: interest on drawn balances, usually a spread over a floating reference rate, and a smaller commitment fee on the undrawn portion that compensates the lenders for standing ready. Availability is often tied to a borrowing base of receivables and inventory, and covenants can block further draws once leverage or coverage tests are breached.

RippleCrypto

Ripple is a payments technology company whose software routes cross-border transfers between financial institutions, and the name is also used loosely for the XRP Ledger, the open blockchain the company helped create. The ledger reaches agreement through a consensus protocol run by a set of validators rather than through mining, so transactions settle in seconds with very low fees. Its native asset, XRP, can act as a bridge currency between two national currencies that lack a direct market.

Risk MeasuresStocksCrypto

Risk measures are the statistics used to quantify how uncertain or how damaging an investment outcome could be. Dispersion measures such as standard deviation and variance describe how widely returns scatter around their average. Relative measures such as beta and tracking error describe movement against a benchmark. Tail measures such as value at risk, expected shortfall and maximum drawdown describe the size of bad outcomes rather than typical ones. Each captures a different failure mode, so portfolio reporting normally shows several together.

Risk-Free Rate of ReturnStocks

The risk-free rate is the return an investor can earn with no expectation of default over a chosen horizon, used as the baseline against which every risky asset is priced. In practice it is proxied by short-dated government debt of the currency in question, such as Treasury bills for dollar cash flows, matched to the horizon being valued. It sets the anchor in discounted cash flow models, in the capital asset pricing model and in the Sharpe ratio. It is not free of inflation or reinvestment risk.

real optionStocks

A real option is the right, without the obligation, to take a future business action whose value depends on how uncertainty resolves: to expand a plant, abandon a project, delay an investment, switch inputs or stage funding in tranches. Standard discounted cash flow treats a project as a single committed decision and therefore misses the value of that flexibility. Option pricing techniques can be adapted to it, but the inputs are far harder to observe than for a traded option, so the discipline is often used qualitatively.

reserve requirementsStocks

Reserve requirements oblige banks to hold a minimum fraction of their deposit liabilities as reserves at the central bank or as vault cash. Historically they served both as a prudential buffer and as a lever on credit expansion, since a higher ratio leaves less to lend. Their role has faded in several advanced economies, where interest paid on abundant reserves replaced them as the policy tool and some central banks set the ratio at zero. Others, notably China, still adjust the ratio actively as a primary instrument.

residual varianceStocksCrypto

Residual variance is the portion of the variability in an asset return that a model fails to explain. Regress the return on a market index or a set of factors, and the fitted part is systematic while the leftover errors are residual; their variance measures firm-specific risk. In portfolio construction it matters because residual risk is diversifiable: combining many positions whose residuals are uncorrelated shrinks the portfolio residual variance while the systematic component remains. It is also the denominator behind the information ratio and appraisal ratio.

Real Asset(real assets) Stocks

A real asset has physical substance and derives value from its use or scarcity rather than from a contractual claim on another party. The category covers real estate, farmland and timberland, infrastructure such as toll roads, pipelines and utilities, energy reserves, industrial metals and precious metals. Because rents, tolls and commodity prices often move with the general price level, real assets are held for their tendency to preserve purchasing power, at the cost of illiquidity, high transaction expense and ongoing maintenance and operating obligations.

Real Estate Investment GroupStocks

A real estate investment group pools money from several investors to buy or build residential or commercial property, most often as a limited liability company or limited partnership, and handles purchase, financing, leasing and maintenance centrally. Investors own units in the entity rather than a specific building, receive a share of rental income and eventual sale proceeds, and rely on the sponsor for operating decisions. Unlike a listed real estate investment trust, the units are private and generally illiquid, and there is no requirement to distribute a set share of income.

Real Estate Short SaleStocks

A real estate short sale is the sale of a property for less than the balance owed on its mortgage, which the lender must approve because it accepts a reduced payoff to release the lien. Lenders consider it when the borrower is in genuine hardship and the alternative is a foreclosure that would recover even less after legal costs and holding time. Whether the shortfall is forgiven or pursued as a deficiency depends on state law and the agreement, and forgiven debt can carry its own tax consequences.

Repurchase AgreementStocks

A repurchase agreement is the sale of a security combined with a commitment to buy it back at a set price on a set date, which makes it economically a secured loan. The cash borrower delivers collateral and pays the difference between the two prices as interest, quoted as the repo rate; the cash lender holds the security and applies a haircut so the collateral is worth more than the cash advanced. It is the main short-term funding market for dealers and a primary tool of central bank operations.

Return on Total AssetsStocks

Return on total assets divides profit by the average assets employed to generate it, measuring how efficiently the balance sheet is being used regardless of how it was financed. Because net income is after interest, the ratio penalizes leverage, which is why some analysts add back after-tax interest to compare capital structures neutrally. Typical levels differ enormously by industry: an asset-heavy utility or airline operates at a fraction of the return a software or services company achieves on the same profit margin.

Right of RescissionStocks

The right of rescission lets a borrower cancel certain loans secured by their principal dwelling within a short window after closing, receiving back finance charges and fees. Under the United States Truth in Lending Act it applies to refinancings with a new lender, home equity loans and lines of credit, and it does not apply to a loan used to buy or build the home itself. The lender must deliver the required notice and disclosures, and failure to do so extends the period during which the borrower may cancel.

Risk AnalysisStocksCrypto

Risk analysis identifies what could go wrong with an investment or project, estimates how likely each outcome is and how large its effect would be, and examines the interaction between them. Quantitative techniques include scenario testing, sensitivity analysis on individual inputs, Monte Carlo simulation of the distribution of results, value at risk and stress testing against historical episodes. Qualitative work covers governance, legal, operational and concentration exposures that resist measurement. The output is a decision about which risks to accept, hedge, transfer or avoid.

Risk-Free AssetStocksCrypto

A risk-free asset delivers a known return over a chosen horizon with no meaningful chance that the payment fails. Short-dated government debt in the currency of the investor is the standard proxy, since the issuer controls the currency in which it must pay. The label is conditional rather than absolute: it addresses default only, leaving inflation risk, reinvestment risk at maturity and currency risk for a foreign holder. It anchors the capital market line and defines the baseline from which risk premiums on every other asset are measured.

Rule 506Stocks

The safe harbor inside Regulation D that lets an issuer raise an unlimited amount privately without registering the offering with the United States Securities and Exchange Commission. Rule 506(b) permits accredited investors plus a limited number of sophisticated non-accredited investors but forbids general solicitation. Rule 506(c) allows public advertising while restricting purchasers to accredited investors and requiring the issuer to take reasonable steps to verify that status.

real-world asset tokenizationCrypto

The process of issuing a blockchain token that represents a legal claim on an off-chain asset such as a Treasury bill, private credit loan, fund share, commodity, or property interest. A custodian or trustee holds the asset, an issuer or transfer agent maintains the link between token holders and legal ownership, and transfer restrictions are often coded into the token. The chain settles transfers while the enforceability of the claim stays with the legal structure.

retirement dateStocks

The year in a target-date fund's name, used as the anchor for its glide path. The fund holds a higher equity weight far from that year and shifts toward bonds and cash as the year approaches. The date is a design parameter rather than a maturity: a to-date fund reaches its most conservative mix at the target year, while a through-date fund keeps de-risking for years afterwards.

RECsStocks

Renewable energy certificates: tradable instruments representing the environmental attributes of one megawatt hour of electricity generated from a renewable source. The certificate separates from the power itself, so a buyer can make a renewable claim without any physical connection to the generator. Compliance markets require utilities to retire a set quantity under state portfolio standards, while voluntary buyers retire them for corporate claims. Retirement once is what prevents double counting.

RESPStocks

Registered Education Savings Plan: a Canadian account for funding a beneficiary's post-secondary education. Contributions are not deductible, growth is sheltered inside the plan, and the federal government adds a matching grant on contributions up to annual and lifetime maximums. Withdrawals of growth and grant are taxed in the student's hands, usually at a low rate. Unused grant must be repaid if no beneficiary attends an eligible program.

RMBSStocks

Residential mortgage-backed security: a bond backed by a pool of home loans and issued without a government-sponsored enterprise guarantee, so investors carry borrower credit risk alongside prepayment risk. The pool is tranched, with subordinate classes absorbing losses before senior ones and excess spread and overcollateralization providing further cushion. Analysis centres on borrower credit quality, loan-to-value at origination, documentation standards, and the servicer's loss-mitigation record.

RMDsStocks

Required minimum distributions: amounts that must be withdrawn each year from tax-deferred retirement accounts once the owner reaches an age set in the Internal Revenue Code. The annual figure is the prior year-end balance divided by a life expectancy factor from IRS tables, and the withdrawal is generally taxed as ordinary income. Missing one triggers an excise tax on the shortfall. Roth IRAs are exempt during the owner's lifetime.

RV parksStocks

Commercial properties renting sites to recreational vehicles and campers by the night, week, month, or season. Revenue combines site rent with income from utilities, stores, laundry, and activities, and occupancy is highly seasonal and weather-dependent. Capital cost per site is low relative to apartments because the tenant supplies the dwelling, while operations are management-intensive with constant turnover. Buyers underwrite them closer to a hospitality business than to a lease-based rental.

Railcar LeasingStocks

Railcar leasing is the ownership of freight rail cars by a lessor that rents them to shippers, industrial companies and railroads. Contracts run from short-term daily arrangements to leases of several years, and may be full service, where the lessor handles maintenance, regulatory compliance and repairs, or net, where the lessee does. Returns come from lease rates, utilization, maintenance cost control, and the residual value of a car with a service life measured in decades. Demand for specific car types tracks the commodities they carry.

Rare Book InvestmentStocks

Rare book investment is the purchase of printed works for their collector value, driven by edition and issue points (a true first printing rather than a later state), the presence of an original dust jacket, condition of binding and text block, association or signature, and the historical importance of the title. Specialist dealers and auction houses set the market, and completeness matters more than most buyers expect, since a missing plate or a supplied jacket can remove most of the value. Storage requires stable humidity and protection from light.

Rare Coin InvestmentStocks

Rare coin investment concentrates on individual coins whose value comes from scarcity and condition rather than metal content. Each candidate is identified by series, date and mint mark, then graded by an independent service on a numeric scale, because prices between adjacent grades for a key date can differ by multiples. Liquidity comes from a dealer network and specialist auctions rather than an exchange, so the spread between what a dealer bids and what a collector pays is wide and materially affects the outcome of a short holding period.

Rare Whisky InvestmentStocks

Rare whisky investment is the purchase of bottled single malts and other aged spirits for resale value, focused on closed distilleries, limited releases, discontinued expressions and old bottlings with documented provenance. Value depends on distillery, age statement, cask type, bottling series, fill level and label condition, and on whether the original packaging survives. The market is auction-driven and concentrated in a few names. Spirits do not mature further once bottled, so the return depends entirely on collector demand, and authentication has become a real concern as prices have risen.

Registered Disability Savings PlanStocks

A Registered Disability Savings Plan is a Canadian long-term savings account for a person eligible for the disability tax credit. Contributions are not deductible, but investment growth is sheltered until withdrawal, and the federal government adds matching grants and, for lower-income beneficiaries, bonds that require no contribution at all. Grants and bonds carry a holdback rule: amounts received within a defined number of years before a withdrawal must be repaid. Contribution and assistance limits, income thresholds and the holdback period are set by the Canada Revenue Agency.

Registered Education Savings PlanStocks

A Registered Education Savings Plan is a Canadian account used to save for a beneficiary's post-secondary education. Contributions are not deductible, but income and government grants accumulate tax-sheltered inside the plan, and the Canada Education Savings Grant adds a matching percentage of annual contributions up to yearly and lifetime maximums. When the beneficiary enrols, withdrawals of grant and accumulated income are taxed in their hands rather than the subscriber's. If no beneficiary attends, grants are repaid and remaining income is taxed with a penalty unless transferred to a registered retirement plan.

Registered Retirement Income FundStocks

A Registered Retirement Income Fund is the Canadian account into which a registered retirement savings plan is normally converted at the end of the year the holder reaches the prescribed age. The assets stay invested and continue to grow tax-deferred, but the holder must withdraw at least a minimum amount each year, calculated from age and the account value at the start of the year, and every withdrawal is taxed as income. There is no maximum. The minimum percentage schedule and the conversion age are set by federal tax law.

Renewable Energy CertificateStocks

A renewable energy certificate represents the environmental attributes of one megawatt hour of electricity generated from a renewable source, issued to the generator by a tracking registry and tradable separately from the electricity itself. A buyer retires a certificate to substantiate a claim that its consumption was matched by renewable generation. Certificates that meet a state's portfolio standard carry a compliance value set by that program, while voluntary certificates trade on corporate demand. Because the attribute travels apart from the power, the claim is an accounting match, not physical delivery.

Revenue Share InvestmentStocks

Revenue share investment provides capital to a business in exchange for a fixed percentage of its revenue until an agreed multiple of the advance has been repaid. Payments scale with sales, so a slow month costs the business less than a fixed loan instalment would, and repayment finishes sooner when growth is fast. The investor takes no equity and usually no board seat, and the effective return depends on how quickly revenue arrives, since the repayment cap is a fixed amount and only the timing determines the annualized rate.

Return on InvestmentStocks

Return on investment expresses the gain or loss from an investment as a percentage of the amount put in: net gain divided by the cost of the investment. Its appeal is that it can be applied to anything, from a security to a marketing campaign to a piece of equipment, and its weakness is that the basic form ignores time. A given percentage earned over one year and the same percentage earned over five are not comparable, which is why annualized or internal rate of return measures are used instead.

racehorse ownership and syndicationStocks

Racehorse ownership and syndication is the practice of buying thoroughbreds outright or through shared entities in which many investors hold fractional interests managed by a syndicate manager or racing partnership. Costs accrue continuously: training fees, veterinary care, transport, insurance, and entry fees are owed whether or not the horse races. Returns come from prize money, which is heavily concentrated in a small number of animals, and from residual breeding or resale value. Because soundness and racing ability cannot be assessed in advance, dispersion of outcomes is extreme and many horses never earn back their costs.

railStocks

Rail as an infrastructure asset class covers freight and passenger railway networks, terminals, and rolling stock. Exposure typically comes through listed railroad operators, private ownership of short line railroads, rolling stock leasing pools, and infrastructure funds holding concession interests. The economics rest on very high fixed costs in track and structures against low incremental cost per additional car, which makes volume and network density central. Concession and regulated systems earn a return set by contract or regulator, while freight railroads price commercially and are exposed to commodity volumes such as coal, grain, and intermodal containers.

ranchlandStocks

Ranchland is rural property held mainly for livestock production, usually combining native pasture, hay ground, and sometimes timber or irrigated cropland. Value per acre is lower than intensively farmed land and is driven by carrying capacity, water resources and rights, fencing and working facilities, road access, and the size of contiguous blocks. Many parcels carry an amenity component from recreation, hunting, and scenery that can exceed the value supported by cattle income alone, so pricing often reflects demand for lifestyle and conservation use as much as agricultural yield.

receivables financingStocks

Receivables financing advances cash against invoices a business has issued but not yet collected. Two main forms exist: factoring, in which the invoices are sold to a funder that then collects from the customer, and asset-based lending, in which invoices secure a revolving line while the borrower keeps collecting. The funder advances a percentage of eligible invoice value, holds the remainder as a reserve released on payment, and charges a discount fee tied to how long the invoice stays outstanding. Recourse terms decide whether the business must repay if the customer never pays.

recurring revenueOptionsStocks

Recurring revenue is income a business can reasonably expect to continue in future periods because it arises from contracts or repeated purchase behavior rather than one-off transactions, typically subscriptions, maintenance agreements, or usage-based contracts with committed minimums. It is measured as annual or monthly recurring revenue by annualizing committed subscription value at a point in time and excluding one-time fees. Analysts pair it with gross and net revenue retention, which show how much of a cohort's revenue survives churn and how far expansion offsets it. Predictability is why it supports higher valuation multiples. Full guide →

regulatory riskStocks

Regulatory risk is the chance that a change in law, rule, or enforcement practice reduces the value or income of an investment. It can arrive as new legislation, an agency rulemaking, a licensing or permitting decision, a shift in how an existing rule is interpreted, or a tax change. Effects range from higher compliance costs and restricted business lines through to outright prohibition of a product or market. It is difficult to hedge because it is not priced continuously, tends to arrive in discrete steps, and often hits every holding in the affected sector or jurisdiction at once.

renewable-energy infrastructureStocks

Renewable energy infrastructure is the physical generation and supporting assets that produce electricity from wind, solar, hydro, geothermal, or biomass, together with the storage and grid connections they require. Investors access it through listed utilities and yield-focused vehicles, private infrastructure funds, and direct project ownership. Cash flow characteristics resemble contracted infrastructure: revenue is often fixed for years through power purchase agreements or government support schemes, operating costs are low and largely fixed, and returns depend on the resource actually available, equipment availability, and the cost of financing.

reservesStocks

In auction markets, the reserve is the confidential minimum price a consignor will accept, agreed with the auction house before the sale. Bidding may open below it, but if the final bid falls short the lot goes unsold, described in the trade as bought in. Reserves are typically set at or below the low end of the published estimate range and are not disclosed to bidders. An unsold lot leaves a public record that can weigh on later attempts to sell the same item, and the consignor may still owe agreed fees.

resortsStocks

Resorts are destination hospitality properties where guests come for the location and on-site amenities rather than for proximity to a business district, including beach, ski, golf, and integrated leisure complexes. Revenue extends well beyond rooms into food and beverage, spa, activities, retail, and events, so total revenue per available room matters more than room rate alone. Demand is highly seasonal and discretionary, capital requirements for maintaining amenities are heavy, and exposure to weather, natural disaster, and travel disruption is direct. Ownership is frequently split among property owner, brand, and operator.

retailStocks

Retail is the commercial real estate sector comprising properties leased to merchants, ranging from single-tenant net lease stores to neighborhood centers anchored by a grocer, power centers, and regional malls. Leases commonly pair a base rent with percentage rent tied to tenant sales, and pass through common area maintenance, taxes, and insurance. Sales per square foot and the occupancy cost ratio, which is rent as a share of tenant sales, indicate whether rents are sustainable. Performance has diverged sharply by format, with necessity-based and service tenants behaving very differently from discretionary goods.

revenue-producing digital assetsStocks

Revenue-producing digital assets are online properties that generate measurable income, including content websites, e-commerce stores, mobile applications, software products, newsletters, and paid communities. They are bought and sold on marketplaces and through brokers, priced as a multiple of trailing monthly or annual profit. Because the underlying asset is intangible, diligence centers on verifying revenue through platform and payment processor records, testing how concentrated traffic and income are in a single channel, confirming that accounts, code, content rights, and supplier relationships actually transfer, and judging how much of the operation depends on the current owner.

rookie cardsStocks

A rookie card is the first mainstream trading card issued for an athlete, usually in the first season of professional play, and it is typically the most sought after card of that player's career. Collectors treat it as the benchmark issue, so demand and price track the player's performance and reputation more closely than for later cards. Which card qualifies is decided by hobby convention and can be contested when several issues appear in the same year. Grade drives price sharply, and the gap between adjacent high grades often exceeds the value of a mid-grade example.

row cropsStocks

Row crops are annual field crops planted, harvested, and replanted each season in spaced rows, principally corn, soybeans, wheat, cotton, and rice. Because the planting decision is made annually, growers can rotate between crops in response to expected prices, input costs, and agronomic needs, which makes row crop land more flexible than land committed to permanent plantings. Land value is driven by soil productivity ratings, drainage, rainfall or irrigation, and proximity to elevators and processors. Leases are commonly cash rent fixed per acre in advance, or crop share arrangements splitting revenue and some inputs.

royalty financingStocks

Royalty financing provides capital to a company or rights holder in exchange for a percentage of the revenue generated by a specific product, mine, drug, or catalog, rather than for equity or a fixed-coupon loan. Payments run for a defined period, until a stated multiple of the advance has been returned, or for the life of the underlying asset. Because the royalty is calculated off gross or net revenue at a defined measurement point, the financier is paid ahead of most operating costs and is exposed to volume and price rather than to the issuer's overall profitability or capital structure.

Range FloaterStocks

A range floater is a note that accrues interest only on the days a reference rate or index sits inside a stated band, and accrues nothing on days it falls outside. The headline coupon is above what a plain floating rate note pays, and the extra yield is the premium the investor earns for selling a strip of digital options on the reference. Income is therefore uncertain and depends on realised volatility as well as on the level of rates.

Real Option ValuationOptionsStocks

Real option valuation prices the managerial flexibility embedded in an investment, treating choices such as deferring a project, expanding it, contracting it or abandoning it as options on the underlying asset. Standard discounted cash flow assumes a fixed plan and therefore undervalues projects whose outcome managers can steer after uncertainty resolves. The technique borrows financial option methods, using the project value as the underlying and the required outlay as the strike, and it is most defensible where the underlying has an observable traded proxy.

RECOUPONINGStocks

Recouponing resets the fixed rate on an existing swap to the current market rate, with the party holding the losing side making a cash payment equal to the contract's mark to market so the swap restarts at zero value. The purpose is to cut accumulated counterparty credit exposure without terminating and rewriting the trade. It is normally provided for in the documentation, triggered at agreed dates or exposure thresholds, and it changes the cash flow profile while leaving the maturity intact.

Relative Value ArbitrageStocks

Relative value arbitrage seeks profit from the price gap between two related instruments rather than from the direction of the market, buying the one judged cheap and selling the one judged rich so that shared risk factors offset. Common versions include convertible bond arbitrage, on the run against off the run government bonds, and pairs of shares in the same industry. Because gaps are small, positions are usually leveraged, which makes funding cost and margin calls central to whether the trade survives long enough to converge.

RESTRUCTURINGStocks

Restructuring is a significant change to a company's capital structure, operations or legal organisation, undertaken to restore solvency or to improve returns. Financial restructuring alters the claims: extending maturities, cutting coupons, exchanging debt for equity or writing principal down, either by consent out of court or through an insolvency process. Operational restructuring changes the business itself through closures, disposals and headcount reduction. In credit derivatives the word is also a defined credit event that can trigger settlement.

Risk-Weighted AssetsStocksCrypto

Risk-weighted assets are a bank's exposures scaled by factors reflecting how risky each is, forming the denominator of regulatory capital ratios. A claim on a highly rated government may carry a zero weight while an unsecured corporate loan carries a full one, and off-balance sheet items are converted into an equivalent exposure first. Weights come either from a supervisory standardised table or from a bank's own approved models, and the aggregate determines how much capital the minimum ratios require.

ROLLOVERStocks

A rollover is the transfer of a balance or a position from one arrangement to a successor without treating it as a final settlement. In retirement accounts it moves assets from one plan or individual account to another, and a direct trustee to trustee transfer avoids the withholding and deadline problems of taking possession first, with the rules and time limits set by the Internal Revenue Service. In futures it means closing an expiring contract and opening the next delivery month, and in funding it means replacing maturing debt with new debt.

Random walkStocks

A random walk is a process in which each successive value equals the previous value plus an independent random shock, so past changes carry no information about future ones. Applied to prices, it implies that today's level is the most accurate available forecast of tomorrow's, adjusted only for an expected drift. The idea underpins the weak form of the efficient market hypothesis and much of continuous-time option pricing, where prices are modelled as geometric Brownian motion. Empirical tests find deviations, particularly over long horizons.

Real Estate Mortgage Investment Conduit(REMIC) Stocks

A real estate mortgage investment conduit is a US entity that holds a fixed pool of mortgages and issues multiple classes of interests to investors. It is the standard legal wrapper for collateralised mortgage obligations because, if the tax code's requirements are met, the entity itself is not taxed and income passes through to holders, avoiding a second layer of tax. Interests are divided into regular classes, which behave like debt, and a single residual class.

Real-Time Gross Settlement(RTGS) Stocks

Real-time gross settlement is a payment system design in which each transfer settles individually and finally the moment it is processed, using funds held at the central bank, rather than being bundled into a net position settled later. Settling gross removes the credit exposure that builds between netting cycles, at the cost of requiring participants to hold more intraday liquidity. Central banks operate these systems for large-value payments, with intraday credit facilities to smooth queues.

Reciprocal currency (swap) arrangementsStocks

Reciprocal currency arrangements, also called central bank liquidity swap lines, are standing agreements under which two central banks exchange their currencies at the prevailing spot rate and agree to reverse the exchange at that same rate on a set future date, with interest paid by the borrowing side. The receiving central bank lends the foreign currency to banks in its own jurisdiction, easing offshore funding shortages. Because the reversal rate is fixed at the outset, neither central bank takes exchange rate risk.

Recourse LoanStocks

A recourse loan allows the lender, after seizing and selling the pledged collateral, to pursue the borrower personally for any shortfall between the sale proceeds and the outstanding balance. That claim can extend to other assets, and in some cases to wages, through a deficiency judgment. A non-recourse loan limits the lender to the collateral alone. Whether a mortgage is recourse depends on the jurisdiction and the loan documents, and the distinction can also affect the tax treatment of forgiven debt.

Relative Valuation ModelOptionsStocks

A relative valuation model values an asset by comparing it with the market prices of similar assets rather than by discounting its own cash flows. The analyst chooses a peer group, standardises price using a multiple such as price to earnings, enterprise value to EBITDA or price to book, and infers a value from where the peers trade. It reflects current market pricing directly, which is also its weakness: if the whole peer group is mispriced, the result inherits that error.

RepudiationStocks

Repudiation is a refusal to honour an obligation, either by declaring outright that a debt or contract will not be performed, or by acting in a way that makes performance impossible. In sovereign debt it describes a government denying the validity of borrowings, which differs from default in that the obligation itself is disowned rather than merely missed. In contract law an anticipatory repudiation entitles the other party to treat the agreement as breached and seek remedies immediately.

Residual IncomeStocks

Residual income is the profit remaining after charging for the capital used to earn it, calculated as net income minus a capital charge equal to equity multiplied by the required return on equity. A positive figure means the business earned more than the cost of the capital invested in it. Valuation models add the present value of expected residual income to current book value. In personal finance the phrase is used differently, meaning recurring income that continues without ongoing work.

Risk-Adjusted Return On Capital(RAROC) StocksCrypto

Risk-adjusted return on capital divides expected return, net of funding costs and expected losses, by the economic capital held against a position or business line, so activities with different risk profiles can be compared on one measure. Banks use it for pricing loans, allocating capital between desks and setting performance targets, since a wide headline margin earned against a large capital requirement may rank below a thinner margin on a low-risk exposure.

Risk-Based Capital RequirementStocksCrypto

A risk-based capital requirement obliges a regulated financial institution to hold capital in proportion to the risk it takes rather than to the size of its balance sheet. Assets are assigned risk weights, and additional charges cover market and operational risk, giving a denominator of risk-weighted assets against which minimum ratios of qualifying capital are measured. Insurers use an analogous formula based on asset, underwriting and interest rate risk. Regulators set the ratios and the weights.

Rollover RiskStocks

Rollover risk is the danger that a borrower cannot refinance maturing debt on acceptable terms, or at all, and must repay from cash, sell assets or default. It rises when a firm funds long-lived assets with short-term borrowings, concentrates maturities in a narrow window, or relies on markets that close quickly under stress such as commercial paper and repo. Lenders and rating agencies examine maturity schedules and committed backup facilities to judge the exposure.

Rule 10b5-1StocksCrypto

Rule 10b5-1 is a US Securities and Exchange Commission rule addressing insider trading. It confirms that trading while aware of material non-public information breaches the securities laws, and it provides an affirmative defence for trades made under a written plan adopted in good faith at a time when the person had no such information. The plan must set amounts, prices and dates or delegate discretion to another party, and the Commission sets conditions including cooling-off periods and certifications.

rampingStocks

Ramping is market manipulation in which a participant buys aggressively to push a price upward, creating the appearance of genuine demand so that others follow and the manipulator can sell into the interest at inflated levels. It is easiest in thinly traded securities where limited depth means modest volume moves the quote, and it is often paired with promotional messaging. Regulators treat it as prohibited conduct under market abuse and securities fraud provisions, and surveillance systems flag the pattern of concentrated buying followed by distribution. Marking the close is a related timing-specific form aimed at the reference price used for valuation.

rate-sensitive liabilitiesStocks

Rate-sensitive liabilities are the funding items on a bank's balance sheet whose cost reprices within a chosen time band, either because they mature and must be replaced or because they carry a floating rate that resets. Money market deposits, short-term certificates, repo funding and floating rate borrowings fall into the category, while long-dated fixed rate debt does not. Asset liability managers set them against rate-sensitive assets in the same band to produce a repricing gap: a bank with more sensitive liabilities than assets sees net interest income compress when rates rise. Gap analysis is a simple screen, and duration and simulation methods refine it.

ratio vertical spreadStocksOptions

A ratio vertical spread buys and sells options of the same type and expiry at different strikes in unequal quantities, most commonly buying one nearer the money and selling two further out. The extra short options can reduce the net cost to zero or produce a credit, and the position profits over a defined range around the short strike. The trade-off is that beyond the short strikes the position is net short options, so loss is unlimited on a call ratio and large on a put ratio, and margin is required. Because the exposure is uncapped, it is treated as an advanced strategy with elevated approval requirements at most brokers.

real return bondStocks

A real return bond is a Government of Canada security whose principal is adjusted for changes in the consumer price index, with the semi-annual coupon paid on the inflation-adjusted principal, so both the income and the amount repaid at maturity keep their purchasing power. The quoted yield is a real yield, and the difference between it and a conventional bond of similar maturity is the breakeven inflation rate, the average inflation at which the two would deliver the same return. It is the Canadian counterpart of United States Treasury inflation-protected securities and United Kingdom index-linked gilts, and Canadian tax rules treat the annual inflation accrual as current income.

realized gainStocks

A realized gain is the profit locked in when an asset is actually sold or otherwise disposed of, measured as the net proceeds less the cost basis. Until that point a rise in value is an unrealized gain that exists only on paper and can still reverse. The distinction matters for reporting and for tax: most jurisdictions tax a gain only on realization, with the treatment depending on how long the asset was held, and realized losses may be offset against gains subject to rules on ordering, carry-forward and wash sales. Basis itself can be adjusted by commissions, return of capital distributions and corporate actions.

reciprocal exchangeStocks

A reciprocal exchange is an unincorporated insurance arrangement in which the participants insure one another, each subscriber acting as both insured and insurer through powers of attorney granted to a manager called an attorney-in-fact. The attorney-in-fact underwrites, issues policies, handles claims and administers the exchange for a fee, but the risk and surplus belong to the subscribers rather than to shareholders. Any underwriting surplus can be returned to subscribers, and some exchanges retain the right to assess members if losses exceed funds held. It is one of several policyholder-owned forms, alongside mutual insurers and fraternal societies, and it is regulated as an insurer by the state where it operates.

rediscountingStocks

Rediscounting is the sale of an already-discounted short-term instrument to another party, classically a commercial bank selling bills it had bought from customers to the central bank in exchange for reserves. The bank receives the face value less a discount computed at the central bank's rediscount rate, so the operation converts illiquid short-term claims into immediately usable funds. Setting that rate and defining which paper is eligible gave central banks a direct lever over the volume and price of credit, and it was the main policy tool before open market operations in government securities became dominant. Discount window lending against collateral is the modern descendant.

reference obligationStocks

The reference obligation is the specific debt instrument named in a credit derivative to define the credit being traded and to anchor how settlement works. It identifies the seniority level and, in documentation terms, the obligation characteristics that determine which other debts of the same entity qualify as deliverable after a credit event. Selecting it matters because a contract written on subordinated debt behaves differently from one on senior unsecured, and because the deliverable set influences the recovery determined at auction. Standard confirmations reference published lists so that contracts on the same entity remain fungible, and successor provisions govern what happens when the issuer merges or the obligation is retired.

refundingStocks

Refunding is the retirement of an outstanding bond issue using the proceeds of a new one, generally to lower interest cost, extend maturity or remove restrictive covenants. Municipal issuers distinguish a current refunding, where the old bonds are called within a short window, from an advance refunding, where proceeds are placed in an escrow of government securities that services the old bonds until their first call date. The escrowed issue is described as defeased. Analysis compares the present value saving against issuance costs and any call premium, and tax rules in the United States restrict when advance refunding may be done on a tax-exempt basis.

regional exchangeStocksCrypto

A regional exchange is a securities market serving a particular geographic area rather than functioning as the primary national listing venue. In the United States exchanges in Boston, Philadelphia, Chicago, Cincinnati and the Pacific coast once listed local companies and provided a second market in nationally listed shares, competing on fees and execution. Consolidation and electronic trading removed most of the geographic rationale, and the surviving venues were acquired by larger groups and now operate as electronic order books within them. The term persists in market structure discussions to describe venues that compete for order flow in securities listed elsewhere.

registrarStocks

A registrar maintains the official record of who owns a company's securities, updating it as shares are transferred and reconciling the total on the register with the amount authorised and issued. It works alongside the transfer agent, and in many markets one institution performs both roles: recording transfers, issuing and cancelling certificates or book entries, and supplying the holder list used for dividends, proxy distribution and voting at meetings. For bonds the registrar tracks holders of registered debt so that payments reach the right accounts. The function guards against over-issuance, which is why it is kept independent of the issuer's own management.

regulatory capitalStocks

Regulatory capital is the loss-absorbing funding a bank or insurer must hold under supervisory rules, defined and measured by regulation rather than by accounting alone. Bank frameworks built on the Basel standards split it into tiers by quality: common equity tier one, made up mainly of ordinary shares and retained earnings, absorbs losses first, with additional tier one and tier two instruments ranking behind it. Requirements are expressed as ratios of capital to risk-weighted assets, supplemented by a leverage ratio that ignores risk weights and by buffers that restrict distributions when breached. Insurance regimes use different measures such as risk-based capital or the solvency capital requirement. Specific minimums are set by each supervisor.

reinsurance creditStocks

Reinsurance credit is the reduction an insurer may take on its regulatory financial statements for liabilities it has ceded to a reinsurer, allowing the ceded reserves to be removed from the balance sheet or offset. Supervisors grant it only when the reinsurer meets defined conditions, historically requiring licensing in the same jurisdiction or, for others, collateral such as trust funds or letters of credit securing the ceded amounts. Regimes have moved toward reduced or eliminated collateral for reinsurers from qualified jurisdictions that meet capital and conduct standards. Without the credit the cedant gets no capital relief from a treaty it has paid for, which is why the rules shape where reinsurance is placed.

replicationOptionsStocks

Replication constructs a portfolio of traded instruments whose payoff matches that of the instrument being valued in every future state. It is the engine of derivative pricing: if a dynamically adjusted holding of the underlying and a cash position reproduces an option's payoff exactly, then the option must cost what that portfolio costs today, or the difference is an arbitrage. The same logic runs in reverse for hedging, since holding the replicating portfolio short neutralizes the exposure. Index funds use the word differently, where full replication means holding every constituent at index weight, as opposed to sampling a representative subset.

repo rateStocks

The repo rate is the interest cost of borrowing cash against securities in a repurchase agreement, expressed as an annualized rate and embedded in the difference between the sale price and the agreed repurchase price. General collateral trades price close to the prevailing overnight rate, because any acceptable security serves as collateral. A specific security in heavy demand for borrowing trades special, and its repo rate falls below the general level, so the owner of that bond earns a financing advantage by lending it out. Rates are also the basis for secured benchmark indices, and persistent pressure in the repo market signals collateral scarcity or balance sheet constraints.

repricing riskStocksCrypto

Repricing risk is the exposure of net interest income to assets and liabilities resetting or maturing at different times. A bank funding long-dated fixed rate loans with short-term deposits sees its funding cost reset upward while asset yields stay fixed, compressing the margin when rates rise; the mismatch works in its favour when rates fall. It is measured with a repricing gap schedule that buckets balances by the date their rate can change, and refined with duration analysis and income simulation across rate scenarios. It is one of several interest rate risks in the banking book, alongside basis risk, yield curve risk and optionality from prepayment and early withdrawal.

reserve assetsStocks

Reserve assets are the external holdings a monetary authority controls and can readily use to meet balance of payments needs, intervene in the currency market or support confidence in the currency. They comprise foreign currency deposits and securities, monetary gold, special drawing rights, and the reserve position at the International Monetary Fund. To qualify, an asset must be liquid, denominated in a convertible currency and under the effective control of the authority, so pledged or encumbered holdings are excluded. Adequacy is judged against import cover, short-term external debt and money supply, and reserve levels are watched closely in economies operating a peg or a managed exchange rate.

residual value guaranteeStocks

A residual value guarantee is a promise that an asset will be worth at least a stated amount at the end of a lease or financing term, with the guarantor making up any shortfall against actual market value. Equipment and vehicle leases use it so the lessor can set lower payments against a higher assumed end value while transferring the disposal risk to the lessee, the manufacturer or an insurer. Lease accounting requires the lessee to include amounts it expects to owe under the guarantee in its lease liability. Pricing depends on the forecast used, which makes the guarantor's exposure sensitive to technology change, regulation and secondary market conditions.

reverse takeover(reverse merger) StocksCrypto

A reverse takeover is a transaction in which a private company gains a stock exchange listing by combining with an already-listed company, issuing so many new shares to the private company's owners that they end up controlling the merged entity. The listed shell is nominally the acquirer in legal form, but accounting standards require the transaction to be presented as an acquisition of the shell by the private business, since that is the economic substance. Sponsors use it to reach public markets faster and with less underwriting than an initial public offering. Exchanges impose their own approval requirements, and diligence on the shell's undisclosed liabilities is the central risk.

reverse to maturityStocks

A reverse to maturity is a reverse repurchase agreement whose term runs to the maturity date of the collateral, so the cash lender holds the security until it redeems rather than returning it on an earlier date. Because the trade covers the full remaining life of the bond, the arrangement locks a financing spread for that period and removes the need to roll the position at unknown future rates. The mirror trade, repo to maturity, is the same structure seen from the cash borrower's side. Accounting and capital treatment turn on whether the transaction is judged a financing or an outright sale, which has been contested in past disputes.

ring tradingOptionsStocks

Ring trading is an open outcry method in which members trade a single contract at a time in short timed sessions, seated or standing in a circle so every participant can see and hear the others. The London Metal Exchange is the best known user, running successive rings for each metal, and the prices established in those sessions have long served as reference points for physical contracts worldwide. Its distinguishing feature is the sequential, time-boxed structure, which concentrates liquidity in one contract at a defined moment instead of spreading it across a continuous session. Electronic platforms now carry most volume, with ring sessions retained mainly for reference pricing.

risk aversionOptionsStocks

Risk aversion is the preference for a certain outcome over an uncertain one with the same expected value, and it is what makes risky assets trade at prices offering a higher expected return than safe ones. In expected utility theory it corresponds to a concave utility function, where each additional unit of wealth adds less satisfaction than the one before, so the pain of a loss outweighs the pleasure of an equal gain. Degrees are measured by coefficients of absolute and relative risk aversion derived from the curvature of that function. The concept underpins portfolio choice, the equity risk premium and the pricing of insurance.

risk retentionStocksCrypto

Risk retention is the deliberate decision to keep an exposure rather than transfer it, funding any loss from internal resources. Organizations retain risks that are frequent and small enough to budget for, using deductibles, self-insured retentions and captive insurers, and they buy cover above the retained layer where a loss would be severe. The same phrase carries a distinct regulatory meaning in securitization: rules adopted after the financial crisis require a sponsor to hold an economic interest in the credit risk of the assets it securitizes, so that its incentives stay aligned with investors. The required share and permitted forms are set by the relevant regulation.

round tripOptionsStocks

A round trip is a complete buy and sell cycle in the same instrument, and the phrase is normally used to describe the total cost of that cycle. Round-trip cost adds commissions on both sides, the bid-ask spread crossed on entry and exit, exchange and clearing fees, any financing charge while the position was held, and market impact, which is why a strategy with a small expected edge can be unprofitable after execution. Futures commissions are often quoted per round turn rather than per side for the same reason. The term also appears in accounting to describe circular transactions that inflate reported volume without economic substance.

risk-neutral valuationOptionsStocks

Risk-neutral valuation prices a derivative as the expected value of its payoff, computed under a probability measure in which every asset is assumed to drift at the risk-free rate, then discounted at that same rate. The device works because the replicating argument makes the derivative's value independent of investors' actual risk preferences: if a portfolio of the underlying and cash reproduces the payoff, no assumption about expected returns is needed. The probabilities used are not forecasts of what will happen; they are adjusted weights that make the arithmetic consistent with no arbitrage. It is the framework behind Black-Scholes, binomial trees and Monte Carlo derivative pricing.

Realized YieldStocks

The return an investor actually earned on a bond over the period it was held, computed from the purchase price, the coupons received, the rate at which those coupons were reinvested, and the proceeds at sale or maturity. It differs from yield to maturity, which assumes the bond is held to the end and every coupon is reinvested at that same yield. Selling early, or reinvesting at different rates, moves the realized figure away from the quoted one.

RatingsStocks

Opinions on the likelihood that a borrower will meet its debt obligations in full and on time, published as letter grades by agencies registered with securities regulators. Grades split at the boundary between investment grade and speculative grade, a line that governs what many insurers, pension funds and index-tracking mandates may hold. Agencies assess business risk, financial leverage, liquidity and any structural or sovereign support, and a downgrade can trigger collateral calls or forced selling written into contracts.

Real Estate Operating Company(REOC) Stocks

A company that owns, develops and manages property but does not elect real estate investment trust status, so it pays corporate tax on its earnings and faces no requirement to distribute most of its income. That freedom lets it reinvest cash flow into development and trade properties actively rather than holding them for income. Investors therefore price it more like an operating business, on earnings growth and development pipeline, than on a distribution yield.

Regulation UStocks

A Federal Reserve rule limiting how much credit banks and other lenders, other than brokers and dealers, may extend where the loan is secured by margin stock and used to buy or carry margin stock. The lender must obtain a purpose statement from the borrower and observe a maximum loan value set as a percentage of the collateral's market value. It is the counterpart to Regulation T, which governs credit extended by brokers, and to Regulation X, which covers borrowers.

Risk-Neutral MeasuresOptionsStocks

Probability weightings under which the discounted price of every traded asset is a martingale, so today's price equals the expected future payoff discounted at the risk-free rate. They are a pricing device rather than a forecast: the weights already embed the market's aversion to risk, which is why expected returns can be replaced by the risk-free rate without changing the answer. Derivatives pricing uses them because the absence of arbitrage guarantees at least one such measure exists, and market completeness makes it unique.

Roll ForwardStocks

Moving a derivatives position from a contract nearing expiry into a later-dated one, by closing the near leg and opening the deferred leg, usually as a single spread trade. The cost or benefit depends on the price difference between the two contracts. When later contracts trade above nearer ones the roll costs money and drags on a long position's returns, and when the curve slopes the other way it adds to them. The term also describes carrying an accounting balance from one period into the next.

RICHStocks

Trading at a higher price, or a lower yield or spread, than a model or a comparable security implies. A bond is described as rich to the curve when its yield sits below the level neighboring maturities suggest, often because it is the current benchmark issue, is scarce in the repo market, or is held in size by buyers who will not sell. The label describes relative pricing only, and richness can persist for as long as the technical support behind it lasts.

Risk PremiumStocksCrypto

The additional expected return an investor requires for holding an asset with uncertain payoffs instead of a default-free claim of the same maturity. It is estimated as the expected return minus the risk-free rate, and for equities is inferred from long-run realized excess returns, from surveys, or from a dividend discount model solved for the discount rate. Credit spreads and term premiums apply the same idea to default risk and to maturity. Estimates are wide and vary with the method used.

Risk WeightsStocks

Percentages applied to a bank's exposures to convert them into risk-weighted assets, the denominator of the regulatory capital ratios. Under the standardised approach the weight comes from a supervisory table keyed to exposure type, external rating and, for property loans, loan to value. Internal ratings-based approaches let approved banks derive weights from their own estimates of default probability and loss given default, within supervisory constraints. Higher weights mean more capital must be held per unit of exposure.

rate anticipation swapStocks

A rate anticipation swap moves a bond portfolio into different maturities because the manager expects interest rates to change. Anticipating lower yields, the manager sells short-dated bonds and buys long ones to lengthen duration and capture more price appreciation. Expecting higher yields, the manager shortens duration to limit the fall. The trade depends entirely on the rate forecast being right, so a wrong call costs more than holding the original bonds.

reinvestment rate riskStocks

Reinvestment rate risk is the chance that interest or principal received before an investment's horizon must be put back to work at a lower rate than the original one. A bond's quoted yield to maturity assumes every coupon is reinvested at that same yield, so falling rates leave the realized return below it. Callable bonds concentrate the problem, since issuers redeem early exactly when rates have fallen. Zero-coupon bonds held to maturity avoid it.

reserve accountStocks

A reserve account is cash or liquid assets set aside in advance to meet a specified future obligation rather than being available for general use. In securitizations a reserve fund absorbs early shortfalls in collections before losses reach the notes. In property finance a replacement reserve funds capital repairs. In project finance a debt service reserve holds several months of scheduled payments. The trigger, required balance and release conditions are set in the governing documents.

reverse transactionsStocks

Reverse transactions are central bank operations that supply or absorb liquidity for a fixed term against collateral, structured either as repurchase agreements or as collateralized loans. The central bank buys securities with an agreement to sell them back, or lends reserves against a pledged pool, so the position unwinds automatically at maturity. Because they are temporary and self-reversing, they are the main instrument for steering short-term money market rates.

Real-Time QuoteStocksCrypto

A price display showing the current bid, offer and last trade as reported by the exchange or consolidated feed, without the fifteen or twenty minute lag applied to free delayed data. Exchanges own their market data and charge for live distribution, so brokers either pass the fee on, absorb it, or show delayed prices by default. Depth of book, which lists resting orders away from the best quote, is normally a separate and costlier subscription. Latency still exists even on live feeds, so a displayed price is what was true a moment ago, not a guaranteed fill.

RecapitalizationStocks

A restructuring of the mix of debt and equity funding a company without necessarily changing what the business does. A leveraged version borrows to buy back shares or pay a large dividend, raising financial leverage and concentrating ownership. The opposite swaps debt for newly issued equity, cutting interest cost and repairing a stretched balance sheet, often as part of a distressed negotiation where lenders accept shares instead of full repayment. Either direction changes who holds the claims, the fixed charges the company must cover, and how sensitive per-share earnings are to a change in operating profit.

RedliningStocks

The practice of denying or pricing credit, insurance or other services differently based on the neighborhood an applicant lives in, where those geographic lines track racial or ethnic composition. The name comes from mid-twentieth-century United States mortgage risk maps that outlined certain areas in red as hazardous, steering lending away from them for decades. It is prohibited under the Fair Housing Act and the Equal Credit Opportunity Act, and the Community Reinvestment Act requires banks to be assessed on lending across the areas they serve. Enforcement cases examine lending patterns and branch placement, not only stated policy.

Registered RepresentativeStocksCrypto

An individual licensed to take securities orders and recommend securities to the public on behalf of a broker-dealer. In the United States the person must be sponsored by a member firm, pass the required qualification examinations, and be registered with the Financial Industry Regulatory Authority and the states where clients live. Their conduct, communications and recommendations are supervised by the firm and subject to conduct rules, including the obligation under Regulation Best Interest to put the retail customer's interest ahead of their own. Registration status and disciplinary history are publicly searchable.

RepaymentStocks

The act of returning borrowed money to a lender, covering both the principal advanced and the interest charged for its use. Schedules differ in how the two components are split: an amortizing loan spreads principal across level payments, an interest-only loan defers all principal to the end, and a bullet or balloon structure pays a large final sum. Early payment reduces total interest but may trigger a prepayment charge where the contract allows one. Missing a scheduled payment can start default remedies set out in the loan agreement and is generally reported to credit bureaus.

Required Rate of ReturnStocksCrypto

The minimum annual return an investor demands to hold an asset given its risk, used as the discount rate when valuing its future cash flows. It builds from a risk-free rate plus compensation for the risks taken, and one common construction adds a market risk premium scaled by the asset's sensitivity to market moves. A higher figure lowers the present value of any given stream of cash flows, so small changes in it move valuations substantially. For a company as a whole the equivalent input is the weighted average cost of capital across debt and equity.

Research AssociateStocks

A junior role on an equity or credit research team supporting the analyst who publishes and is licensed to speak to clients. The work is model building and maintenance, gathering data from filings and industry sources, drafting sections of notes, updating earnings estimates after results, and answering client data requests. In the United States the role generally requires the relevant securities licences before the person can contribute to published research or speak with clients, and research staff are separated from investment banking by information barriers designed to keep deal pressure out of published views.

Research ReportFuturesStocks

A written analysis of a security, sector or market produced by a brokerage, independent research firm or bank, typically containing a recommendation, a target price or valuation range, forecasts and the reasoning behind them. Regulated versions must disclose conflicts: whether the firm makes a market in the security, holds a position, has done investment banking work for the issuer, and how analysts are compensated. Ratings scales vary between firms, so a neutral rating at one house is not equivalent to another's. The disclosures at the back are as informative as the recommendation on the front.

Return on Average Capital EmployedStocks

A profitability measure dividing operating earnings before interest and tax by the average amount of long-term funding used during the period, where that funding is total assets less current liabilities. Averaging the opening and closing denominator matters for businesses that made a large acquisition or disposal mid-year, because an end-of-period figure would compare a full year of profit against a base that existed only briefly. The result shows how much operating profit each unit of long-term funding generated, independent of the debt and equity split, so it is used to compare capital-intensive companies with different financing.

Return on Average EquityStocks

Net income divided by the mean of opening and closing shareholders' equity, showing what a company earned on the owners' book capital across the period. Averaging the denominator prevents distortion when a large share issue, buyback or dividend moves the equity base part way through the year. Banks report it prominently because their business is turning capital into net interest and fee income under a regulatory capital constraint. A high reading can come from strong margins or simply from thin equity supporting a large balance sheet, so it is read alongside leverage.

Return on Capital EmployedOptionsStocks

A profitability ratio dividing operating earnings before interest and tax by the long-term funding supporting the business, calculated as total assets less current liabilities. Because the numerator sits above interest expense and the denominator combines debt and equity, the result measures how productively the whole funding base is used rather than how the returns are split between lenders and owners. Comparing it with the weighted average cost of capital shows whether operations are creating or consuming value. Book-value denominators understate replacement cost, so older asset bases can flatter the figure.

Return on Net AssetsStocks

Net income divided by the sum of fixed assets and net working capital, showing profit generated per unit of the resources actually tied up in operations. It penalizes a business that carries bloated inventory or slow receivables, because those inflate working capital in the denominator without adding profit, and it rewards one that runs lean or negotiates supplier terms that fund the operating cycle. Manufacturers use it to compare plants or divisions on an equal footing. Heavily depreciated assets shrink the denominator and can flatter an ageing operation.

Return on SalesStocks

Operating profit divided by revenue, expressing how many cents of operating earnings each unit of turnover produces. Because it stops above interest and tax, it isolates operating efficiency from financing choices and tax jurisdiction, which makes it useful for comparing similar businesses. It is structurally different across sectors: a discount grocer runs on thin margins with rapid stock turnover, while a software company can show a wide margin on far lower volume, so the level means little without a peer group. The trend over several periods usually carries more information than any single reading.

Risk AssessmentStocksCrypto

A structured process of identifying what could go wrong, estimating how likely each outcome is and how large the loss would be, and ranking the results so attention goes to the exposures that matter most. In investing it covers market, credit, liquidity, currency, concentration and operational exposures, quantified with tools such as volatility, drawdown history, scenario analysis and stress tests. It is an input to a decision, not a forecast: the estimates depend on the history and assumptions used, and events outside that sample are precisely the ones the exercise is least able to size.

Roy's Safety-First CriterionStocksCrypto

A portfolio selection rule that ranks alternatives by how far their expected return sits above a minimum acceptable level, measured in standard deviations. The chosen portfolio is the one with the highest score, since under an assumption of normally distributed returns that also minimizes the probability of falling below the threshold. Setting the threshold to the risk-free rate reduces the calculation to the Sharpe ratio, so the two are close relatives. The framework matches investors who face a hard floor, such as a required funding level, rather than a general aversion to variability.

Russell 1000 IndexStocksCrypto

A capitalization-weighted index of the largest United States companies by market value, drawn as the top segment of the broader Russell 3000 universe, with the remainder forming the small-capitalization Russell 2000. Membership is set by an annual reconstitution using market value on a ranking date, plus quarterly additions for new listings, and the rebalancing generates heavy trading as index-tracking funds adjust. Because it reaches further down the size scale than a 500-stock benchmark, it captures more of the mid-capitalization segment while still being dominated by the largest names through cap weighting.

rainmakerStocks

A rainmaker is a person who generates a disproportionate share of a firm's revenue by winning mandates, raising assets or bringing in clients, rather than by executing the work. The term is used in investment banking, law and asset management, where relationships rather than capacity decide which firm is hired. Pay is typically tied to originated revenue, which concentrates business risk: when a rainmaker leaves, client relationships often move too, so firms use deferred compensation and team coverage to blunt it.

rate-sensitive assetsStocks

Rate-sensitive assets are the assets on a bank's balance sheet whose yield will reset, mature or otherwise reprice within a specified time band, so their income moves with market interest rates during that period. Floating-rate loans, short-dated securities, interbank placements and maturing fixed-rate loans qualify, while a long fixed-rate mortgage does not until its band arrives. Comparing them with rate-sensitive liabilities in the same band produces the repricing gap used to estimate how net interest income responds.

receiverStocks

A receiver is a person appointed, usually by a secured creditor under its security documents or by a court, to take control of specified assets of a defaulting borrower, manage or sell them, and apply the proceeds to the secured debt. The appointment covers the charged assets rather than the whole company, which distinguishes it from a liquidation. In interest rate swaps the same word names the counterparty that receives the fixed rate and pays the floating one.

related-party transactionStocks

A related-party transaction is a deal between a company and someone able to influence it or be influenced by it: a controlling shareholder, a director or officer, a close family member, or an entity under common control. The concern is that terms may not be at arm's length, so accounting standards and securities rules require disclosure of the relationship, the amounts involved and the terms, and boards typically route approval to independent directors with no interest in the outcome.

reopeningStocks

A reopening is the sale of additional securities carrying the same coupon, maturity date and identifier as an existing issue, so the new bonds are fungible with the old and trade as a single line. Treasuries and other sovereigns reopen benchmarks to build issue size and improve secondary liquidity without creating another maturity point. Buyers pay accrued interest from the original dated date, and because the coupon is fixed, the auction price adjusts to reflect the yield demanded.

repackagingOptionsStocks

Repackaging is the process of placing an existing security into a special purpose vehicle and issuing new notes against it whose terms differ from the original: a different currency, a fixed rather than floating coupon, a shorter maturity, or an added credit or equity component. Swaps inside the vehicle convert the underlying cash flows into what the note pays. It exists because investors face mandate, tax or accounting constraints that the original instrument fails and the repackaged note satisfies.

risk factorStocks

A risk factor is a variable that drives the returns of many assets at once, so exposure to it cannot be diversified away within that market. Interest rate level, credit spreads, inflation, currency, liquidity and equity market direction are common examples, and models express an asset's return as its sensitivity to each factor plus a residual. In corporate filings the same phrase names the section where a company sets out contingencies that could materially harm its business.

risk quantificationStocksCrypto

Risk quantification turns exposure into a number that can be compared, aggregated and limited. Common outputs are the standard deviation of returns, value at risk for a chosen confidence level and horizon, expected shortfall for losses beyond that level, sensitivity measures such as duration or delta, and modeled losses under specified stress scenarios. Every figure inherits the assumptions used to produce it, so a quantified risk is a statement about a model and its data window, not a measured physical quantity.

rate of returnStocks

Rate of return expresses the gain or loss on an investment as a percentage of what was originally committed: ending value plus income received, minus beginning value, all divided by beginning value. Stating one requires three things to be fixed: the period it covers, whether income is assumed reinvested, and whether it is nominal or adjusted for inflation. Figures spanning different lengths of time are made comparable by annualizing, which compounds rather than simply scales the periodic result.

Real options theoryOptionsStocks

Real options theory applies option pricing logic to physical investment decisions, treating managerial flexibility as something with measurable value. A project that can be expanded, delayed, staged, switched to another input or abandoned carries rights resembling calls and puts on the underlying business, and those rights are worth more when uncertainty is greater. Standard discounted cash flow valuation assumes a fixed plan and therefore undervalues such projects, while the theory supplies a framework for pricing the choices management retains.

Random Walk TheoryOptionsStocks

Random walk theory holds that successive changes in asset prices are statistically independent, so past movements carry no usable information about future ones and price charts cannot be extrapolated. It follows from the idea that prices already reflect available information and move only when new information arrives, which by definition is unpredictable. The theory is closely tied to the efficient market hypothesis and is used to argue that consistent outperformance from timing is difficult. Empirical work finds departures from strict independence, which is why the debate continues.

Real Economic Growth RateStocks

The real economic growth rate is the percentage change in a country's output after removing the effect of price changes, so it measures actual increases in the volume of goods and services rather than inflation. It is computed from gross domestic product valued at constant prices, using a deflator to convert nominal figures to a common price base. Comparing it with population growth gives real growth per person, which is the measure more closely related to changes in average living standards.

Real Effective Exchange Rate(REER) StocksFutures

The real effective exchange rate measures a currency's value against a basket of trading partners' currencies, weighted by trade shares and adjusted for differences in price levels or unit labour costs. It shows whether a country's goods have become cheaper or more expensive relative to competitors, which the bilateral nominal rate alone cannot reveal. A rise indicates a loss of price competitiveness, and international institutions publish the series as an input to external balance assessments.

Real Estate AgentStocks

A real estate agent is a licensed intermediary who represents a buyer or a seller in a property transaction, marketing the property, sourcing and screening counterparties, negotiating price and terms and coordinating the steps to closing. Compensation is normally a commission calculated on the sale price and paid at completion under the terms of the engagement. Agents generally work under a supervising broker, and licensing, continuing education and duties owed to the client are set by state or national regulators.

Real Estate Owned(REO) Stocks

Real estate owned is property a lender has taken onto its own balance sheet after a foreclosure sale failed to attract a bid covering the outstanding debt. The lender becomes the owner, responsible for taxes, insurance, maintenance and marketing the asset for resale, and typically sells it as quickly as practicable because holding property is outside its business and consumes capital. Such sales are usually made without the disclosures a private seller provides and without repairs, which is reflected in the price.

Real gross domestic productStocksCrypto

Real gross domestic product is the total value of goods and services produced in an economy over a period, measured at the prices of a chosen base year so that changes reflect volume rather than inflation. It is derived from nominal output using a price deflator, and modern practice chains the weights so the base period updates continuously. It is the headline measure of economic activity, and its quarterly change defines the conventional shorthand for expansion and contraction.

ReceiptOptionsStocks

A receipt is a document acknowledging that payment has been made or that goods or assets have been delivered, and it serves as evidence of the transaction for accounting, warranty, tax and dispute purposes. In business bookkeeping receipts support the entries recorded in the ledger and are the substantiation tax authorities expect for claimed deductions. The word is also used in the plural for the total money a business or government takes in over a period, and in securities markets for instruments such as depositary receipts that represent a claim on an underlying asset.

Receivables Turnover RatioStocks

The receivables turnover ratio measures how many times in a period a business collects its average outstanding customer balances, calculated as net credit sales divided by average accounts receivable. A higher figure means cash is collected faster and less working capital is tied up in unpaid invoices, while a falling figure can signal looser credit terms or deteriorating customer quality. Dividing the days in the period by the ratio converts it into days sales outstanding, which many analysts find easier to interpret.

ReceivershipStocks

Receivership is a legal process in which a court or a secured creditor exercising a contractual power appoints a receiver to take control of specified assets or an entire business, in order to preserve value and repay the debt. The receiver's duty runs primarily to the appointing creditor and can include running the operation, selling assets or winding it down. It differs from bankruptcy in that it targets particular collateral rather than reorganising all claims, and control passes from directors to the receiver for the assets covered.

RecourseStocks

Recourse is a lender's right to pursue the borrower personally, and to reach assets beyond the pledged collateral, when a loan is not repaid in full. With full recourse the lender can seek a deficiency judgment for any shortfall after the collateral is sold, and with limited recourse the claim is capped or restricted to defined circumstances. In factoring and securitisation the term describes whether the seller of receivables must make the buyer whole for accounts that never pay, which determines who carries the credit risk.

RefinanceStocks

To refinance is to replace an existing debt with a new one, using the proceeds of the new loan to retire the old balance. Borrowers do it to lower the interest rate, extend or shorten the term, switch between fixed and floating pricing, consolidate several debts or withdraw accumulated equity in a cash-out transaction. The decision turns on whether the savings over the expected holding period exceed the closing costs, prepayment charges and the effect of restarting the amortization schedule.

Regulation OStocks

Regulation O is a Federal Reserve rule governing credit that a United States bank extends to its own insiders, meaning executive officers, directors, principal shareholders and their related interests. It requires such loans to be made on substantially the same terms as those offered to comparable outside borrowers, to involve no more than normal risk of repayment, to fall within aggregate and individual limits tied to the bank's capital, and in defined cases to be approved in advance by the board with the interested party abstaining. Records must be maintained for examiners.

ReinvestmentStocksCrypto

Reinvestment is the use of income generated by an investment, such as dividends, interest or fund distributions, to buy more of the same or another asset instead of taking the cash. It is what turns a simple return into a compounding one, because the newly purchased units then generate income of their own. Automatic dividend reinvestment plans do this without a separate instruction. Reinvestment risk is the related exposure that cash arriving from maturing bonds or called issues must be redeployed at a lower prevailing rate.

Research AnalystsStocks

Research analysts study companies, industries or securities and publish conclusions used to guide investment decisions. Sell-side analysts at brokerages produce reports, earnings estimates and ratings distributed to clients, while buy-side analysts at asset managers work for their own firm's portfolios and do not publish externally. Rules introduced after conflicts of interest surfaced in the early 2000s separate research from investment banking, restrict how analysts are compensated and require disclosure of the firm's business relationships with covered companies.

Reserve Bank of India(RBI) Stocks

The Reserve Bank of India is India's central bank, established in 1935, responsible for issuing currency, conducting monetary policy under an inflation targeting framework set with the government, regulating and supervising banks and many non-bank financial firms, managing foreign exchange reserves and overseeing payment systems. Policy rates are decided by a monetary policy committee, and the bank also administers reserve requirements such as the cash reserve ratio and statutory liquidity ratio that shape credit conditions.

Residual DividendStocks

A residual dividend policy pays shareholders only what is left after the company has funded every investment project that meets its return threshold, using retained earnings before turning to external finance. The logic is that capital should go first to opportunities earning above the cost of capital, since paying out and then issuing shares or debt incurs transaction costs. The consequence is a payout that swings with the capital budget from year to year, so firms wanting a stable dividend usually apply the principle to a long-run target instead.

Resolution Trust Corporation(RTC) Stocks

The Resolution Trust Corporation was a United States government agency created in 1989 to resolve savings and loan institutions that failed during the thrift crisis. It took over insolvent thrifts, honoured insured deposits and disposed of the real estate and loan portfolios left behind, pioneering bulk auctions, equity partnerships and early securitisation of commercial mortgages to sell assets at scale. It closed in 1995, with remaining responsibilities transferred to the Federal Deposit Insurance Corporation, and its methods informed later crisis resolution efforts.

Retail BankingStocks

Retail banking is the business of providing financial services to individual consumers and small businesses rather than to corporations or institutions. Its core products are current and savings accounts, payment services, cards, personal loans and mortgages, delivered through branches, telephone and digital channels. The economics rest on gathering low-cost deposits and lending them at a wider spread, plus fee income, and the deposit base is protected by insurance schemes and by regulation covering conduct, disclosure and consumer credit.

Retirement Money Market AccountStocks

A retirement money market account is a money market deposit or fund held inside a tax-advantaged retirement account such as an individual retirement account. It holds short-dated, high-quality instruments and is used as the cash position within the account, receiving contributions and the proceeds of sales before they are invested elsewhere, and holding funds set aside for withdrawals. Interest accrues under the tax rules of the surrounding account rather than being taxed each year, and withdrawal rules follow those of the retirement account itself.

Retirement PlanningStocks

Retirement planning is the process of estimating the income a household will need once employment ends and arranging saving, investment and benefit choices to meet it. It involves projecting spending, accounting for inflation and longevity, valuing state and employer pension entitlements, choosing account types with different tax treatment, setting a contribution rate and asset allocation, and later deciding a withdrawal approach. Plans are revisited as circumstances, tax rules and market conditions change, since the projections rest on assumptions that will not hold exactly.

Return on Average Assets(ROAA) Stocks

Return on average assets measures how much profit an institution generates from each unit of its asset base, calculated as net income divided by average total assets over the period. Averaging the denominator across opening and closing balances avoids distortion when the balance sheet grows or shrinks during the year. It is the standard profitability yardstick for banks, because their earnings come from deploying assets, and it can be decomposed into asset yield, funding cost, fee income and credit charges to show what is driving the result.

Return on Risk-Adjusted Capital(RORAC) StocksCrypto

Return on risk-adjusted capital measures profit against an amount of capital scaled to the riskiness of the activity, calculated as net income divided by risk-weighted assets or by economic capital allocated to the business. By charging riskier lines more capital, it lets a bank or insurer compare a low-margin, low-risk business with a high-margin, high-risk one on a consistent basis, which a simple return on equity cannot do. It is used in internal capital allocation, pricing and performance measurement.

Returned Payment FeeStocks

A returned payment fee is a charge a creditor or merchant applies when a payment fails because the payer's account lacks sufficient funds, the account is closed or the instruction is rejected. It is distinct from the overdraft or insufficient funds fee the payer's own bank may charge for the same event, so a single failed payment can produce charges on both sides. Amounts are set by contract and are constrained in some jurisdictions by consumer credit rules requiring the charge to reflect actual cost.

Ricardian equivalenceStocks

Ricardian equivalence is the proposition that whether a government funds spending by taxing now or by borrowing makes no difference to aggregate demand, because forward-looking households recognise that debt implies higher taxes later and save the tax cut to meet them. If it held exactly, deficit-financed stimulus would be offset by higher private saving. The argument requires households to be far-sighted, to face no borrowing constraints, and to care about the tax burden falling on later generations, and empirical work generally finds only partial offset.

Right of First OfferStocks

A right of first offer obliges an owner who decides to sell an asset to present it to the holder of the right before approaching the wider market, on terms the owner specifies. If the holder declines, the owner may sell to anyone else, though usually not on terms more favourable than those offered first. It is weaker than a right of first refusal, which lets the holder match a deal already negotiated with a third party, and it is common in property leases, joint ventures and shareholder agreements.

Ring-FenceStocks

To ring-fence is to separate a set of assets, activities or liabilities so they are legally and financially insulated from the rest of an organisation. Banking regulators in some jurisdictions require retail deposit-taking to be placed in a subsidiary with its own capital and governance, so that losses in trading or investment banking cannot reach insured deposits. The same technique appears in project finance, where a project sits in its own entity, and in tax rules that confine losses from one activity to income from that activity.

Risk NeutralStocksCrypto

A risk-neutral decision maker judges an uncertain outcome only by its expected value and requires no additional compensation for variability, so a certain amount and a gamble with the same average are treated as equivalent. Real investors generally behave as risk averse, demanding a premium for uncertainty. The concept nonetheless does essential work in derivative pricing, where valuation is carried out in an artificial world in which all assets are assumed to earn the risk-free rate, because the resulting price is the one that prevents arbitrage.

Risk ProfilesStocksCrypto

A risk profile is a structured description of how much uncertainty an investor or an organisation is able and willing to bear, and of the specific exposures it already carries. For an individual it combines capacity, meaning the financial ability to absorb loss given horizon, income and obligations, with tolerance, meaning the behavioural willingness to sit through declines. Advisers document it before recommending an allocation, and firms build an equivalent picture of market, credit, liquidity and operational exposures to set internal limits.

Risk-Return TradeoffStocksCrypto

The risk-return tradeoff is the principle that assets expected to deliver higher returns generally carry greater uncertainty about the outcome, because investors will not accept extra variability without the prospect of extra compensation. It underlies the equity risk premium, the extra yield demanded on lower-rated credit, and the pricing models that relate expected return to systematic risk. It is a tendency in expectations rather than a promise: taking more risk widens the range of results in both directions, including permanent loss of capital.

Rule 10b-18StocksCrypto

Rule 10b-18 is a United States Securities and Exchange Commission safe harbour that protects a company repurchasing its own shares from manipulation claims, provided the buying follows four conditions on a given day. All purchases must be made through a single broker, they must be timed to avoid the opening and the final minutes of trading, the price must not exceed the higher of the highest independent bid and the last independent transaction price, and daily volume must stay within a set share of average trading volume. The safe harbour is voluntary and provides no protection against fraud.

Rule 72(t)Stocks

Rule 72(t) is the provision of the United States Internal Revenue Code that lets an account holder take money from an individual retirement account or similar plan before the normal age threshold without the additional early distribution tax, provided the money comes out as substantially equal periodic payments. The amount is fixed using one of the calculation methods the Internal Revenue Service permits and must continue for at least five years or until the age threshold is reached, whichever is longer. Modifying the schedule early triggers retroactive penalties plus interest, and income tax still applies to each distribution.

Russell 3000 IndexStocks

The Russell 3000 Index tracks roughly the three thousand largest publicly traded companies in the United States by market capitalisation, covering the large majority of investable domestic equity value. Constituents are weighted by float-adjusted market capitalisation and the membership is reconstituted annually, with new listings added during the year. It splits into the Russell 1000 of larger companies and the Russell 2000 of smaller ones, and it serves as a broad market benchmark and as the basis for index funds seeking total United States equity exposure.

ratio writingOptionsStocks

Ratio writing is selling more option contracts than the position being hedged or than the options held long, so the sold and held quantities are unequal. A holder of one hundred shares who sells two calls, or a trader who buys one option and sells two further out of the money, is ratio writing. The extra premium improves the return if the underlying stays within a range, but the uncovered portion leaves exposure that grows as the market moves through the short strike, and margin is required against it. Losses on the uncovered part are not bounded by the premium received.

reciprocityStocksCrypto

Reciprocity is an arrangement in which two parties direct business to each other in return for the same treatment, rather than choosing each transaction on its merits. In securities markets it has described institutions placing brokerage orders with firms that send them referrals or research, which raises the question of whether the client's execution quality was the deciding factor. In trade and financial regulation the term describes granting firms from another country access on the same terms one's own firms receive there, a principle used both to open markets and to justify restricting access when it is not returned.

redemption valueStocks

Redemption value is the amount the issuer pays a holder when a security is retired, which for a straight bond held to maturity is normally its face value. It can differ from face value where the terms provide otherwise: a bond called early may be redeemed at a premium above par under a schedule set in the indenture, an index-linked bond redeems at an amount adjusted for inflation, and preferred shares often carry a stated redemption price. The figure matters for calculating yield to maturity or yield to call, since it is the final cash flow being discounted.

reference entityStocks

The reference entity is the borrower whose creditworthiness a credit default swap is written on, and whose default or restructuring triggers payment under the contract. The parties also specify reference obligations, particular debts of that entity used to determine seniority and what may be delivered or valued in settlement. Contracts turn on legal identity rather than commercial group, so a swap on a parent gives no protection against a subsidiary's default, and corporate reorganisations require rules on which successor inherits the contract. A determinations committee decides whether a credit event has occurred, and an auction sets the settlement price.

registered securityStocksCrypto

A registered security records the owner's name on a register maintained by the issuer or its agent, so payments go to the recorded holder and a transfer requires the register to be updated. It contrasts with a bearer security, where possession of the certificate establishes entitlement and coupons are claimed by presenting them. Registration lets the issuer identify holders, supports withholding and information reporting, and allows a lost holding to be replaced, which is why most jurisdictions moved away from bearer form for tax and anti-money-laundering reasons. The term separately means a security registered with a regulator for public sale.

regulatory compliance riskStocks

Regulatory compliance risk is the risk that a firm suffers legal penalties, regulatory sanctions, financial loss or reputational damage because it fails to observe the laws, regulations, codes and internal standards applying to its business. It differs from the risk that the rules themselves change. It is managed through a compliance function that identifies applicable obligations, translates them into policies and controls, trains staff, monitors and tests adherence, and reports breaches to senior management and the board. Supervisors increasingly hold named individuals accountable for specific areas, so governance and evidence of oversight matter as much as the underlying controls.

reinsurance capacityStocks

Reinsurance capacity is the total amount of cover reinsurers are willing to provide for a class of risk at a point in time, determined by the capital they hold, their appetite for that exposure and the returns available elsewhere. It moves in cycles: large catastrophe losses erode capital and reduce capacity, which pushes prices up and attracts new capital, including through insurance-linked securities and sidecars, until abundant capacity pushes prices down again. Because primary insurers rely on reinsurance to write large limits, capacity in that market directly affects what cover is available to policyholders and at what price.

reinsurance sidecarStocks

A reinsurance sidecar is a special purpose vehicle funded by outside investors that takes a quota share of a specific book of a sponsoring insurer's business for a limited period, usually one or two years. Investors' money is held in trust to collateralise the obligations, so the ceding insurer is not exposed to the vehicle's credit, and investors receive premiums less losses and expenses. The structure lets an insurer add capacity quickly when prices are attractive without raising permanent capital, and gives investors an insurance return largely uncorrelated with financial markets. The vehicle is wound up when the exposure period ends.

reschedulingStocks

Rescheduling is an agreement between a borrower and its creditors to change the repayment terms of existing debt, usually by extending maturities and deferring principal, sometimes with a grace period or a revised interest rate. It is used where the borrower is judged illiquid rather than insolvent, so lengthening the schedule allows repayment in full over a longer period rather than writing debt off. Sovereign rescheduling has historically been negotiated with official creditors as a group and separately with commercial banks. Where the debt burden itself is unsustainable, rescheduling only postpones the problem and a reduction in principal is needed instead.

restoration premiumStocks

A restoration premium is the additional amount a ceding insurer pays to bring a reinsurance layer back to its full limit after a loss has consumed part or all of it. Excess of loss treaties usually provide a limited number of restorations, and the premium is commonly calculated in proportion to the amount of limit restored and to the portion of the treaty period remaining. Without such a provision, a single large event would leave the insurer unprotected for the rest of the year. The cost of restoration is part of the true price of the cover, and it is often called a reinstatement premium.

retrocessionStocks

Retrocession is reinsurance bought by a reinsurer, passing part of the risk it has accepted to another company called the retrocessionaire. It lets reinsurers manage accumulations from catastrophe exposures and write larger lines than their own capital would support. The practice can create spirals, where risk ceded out returns through several intermediaries so a single event produces claims circling back to the original cedant, a problem exposed in the London market's losses of the late 1980s and early 1990s. In fund distribution the same word means a share of management fees paid to a distributor, which disclosure rules in several jurisdictions require to be revealed or rebated.

revalorizationStocksFutures

Revalorization is the official restatement of the value of a currency or of recorded asset values, usually upward, to reflect changed economic conditions. As a currency measure it describes raising the official parity of a currency, the opposite of devaluation, or replacing a currency that has lost most of its value with a new unit at a stated conversion rate. In accounting it describes restating asset values, and in some jurisdictions pension or wage entitlements, by an index so figures recorded in earlier periods remain comparable after inflation. The purpose in each case is to restore a meaningful relationship between recorded and current values.

reverse mortgageStocks

A reverse mortgage lets an older homeowner borrow against the equity in their home and receive the money as a lump sum, a line of credit or regular payments, with no repayment required while they continue to live there. Interest is added to the balance instead of being paid, so the debt grows over time and the equity remaining shrinks. The loan becomes due when the borrower sells, moves out permanently or dies, and is usually repaid from the sale proceeds. Age requirements, counselling obligations and limits on the amount available are set by the programme or lender and change over time.

right of substitutionStocks

A right of substitution allows one party to replace an asset with an equivalent one during the life of a contract. In collateralised lending, repo and securities lending the borrower may swap the securities pledged for others of agreed quality and value, which lets it recall a specific security needed for delivery elsewhere while keeping the financing in place. In a futures contract with a deliverable basket, the seller's freedom to choose among eligible instruments performs a similar function and gives rise to the cheapest to deliver option. The right is valuable to whoever holds it and is priced accordingly.

ring-fencingStocksCrypto

Ring-fencing separates part of a business or a pool of assets so it is legally and financially insulated from the rest of the group, with its own capital, governance and restrictions on transactions with affiliates. In banking it is used to keep retail deposit-taking and payments away from trading and investment banking activity, so essential services can continue if other parts of the group fail. Utility regulators use the same technique to stop a regulated network subsidising or being drained by unregulated ventures. The protection is only as strong as the restrictions, since intra-group exposures can otherwise reconnect the parts.

rising bottomStocks

A rising bottom is a chart formation in which successive lows in a price series are progressively higher, forming an upward sloping line beneath the price even where the highs are flat or irregular. Technical analysts read it as buyers becoming willing to step in earlier on each pullback, and it is the defining feature of an uptrend and of patterns such as the ascending triangle. A break below the rising line is treated as evidence the pattern has failed. Like all pattern reading it describes what has already happened and offers no assurance the sequence continues.

risk financingOptionsStocks

Risk financing covers the arrangements an organisation makes to pay for losses that occur, as opposed to loss control, which tries to stop them occurring. The choices are retention, funding losses from cash flow, reserves or a captive insurer, and transfer, buying insurance or using contractual indemnities and capital market instruments such as catastrophe bonds. Most programmes combine the two through deductibles and excess layers, retaining predictable high-frequency losses where insurance would simply return the same money less expenses, and transferring the infrequent large losses that could threaten solvency. The mix is reviewed as the cost of cover changes.

risk identificationCrypto

Risk identification is the first stage of a risk management process, in which an organisation systematically finds and records the exposures that could affect its objectives, before any attempt to measure or treat them. Techniques include reviewing operations and contracts, inspecting sites, analysing loss history, interviewing staff at every level, using checklists and standard exposure classifications, and running structured workshops on what could go wrong. The output is a register describing each exposure, its causes and what it would affect. Anything missed here is left uncontrolled by every later stage, which is why breadth matters more than precision at this point.

risk management processStocksCrypto

The risk management process is the repeating cycle an organisation uses to handle uncertainty: establish the context and objectives, identify exposures, analyse their likelihood and consequence, evaluate them against defined criteria, treat them by avoiding, reducing, transferring or retaining, then monitor and review as conditions change, with communication and consultation running throughout. International standards set out this sequence so decisions can be documented and audited. Its value lies in being systematic and recurring rather than in any single step, because exposures and the organisation's tolerance for them both change over time.

risk poolingStocksCrypto

Risk pooling combines many independent exposures so the average outcome becomes more predictable than any single one, which is the mechanism underlying insurance. As the number of similar, uncorrelated units in the pool grows, the variability of the average loss per unit falls in proportion to the square root of the number, so an insurer can charge a premium close to the expected loss and still be confident of meeting claims. The mechanism weakens when exposures are correlated, as with earthquake or pandemic losses, since correlated events strike the whole pool at once, which is why such risks need reinsurance or public backing.

risk transferStocksCrypto

Risk transfer shifts the financial consequences of a possible loss from one party to another in exchange for a payment or another concession. Insurance is the standard form, and contractual indemnities, hold-harmless clauses, guarantees, hedging with derivatives and capital market instruments such as catastrophe bonds achieve the same effect by different mechanisms. Transfer moves the cost, not the event, so the transferring party still faces the operational disruption and retains any exposure the contract excludes, limits or leaves ambiguous. It also introduces counterparty risk, since the arrangement is only as good as the transferee's ability to pay when the loss occurs.

rolling down the curveStocks

Rolling down the curve is holding a bond on an upward sloping yield curve so that, as time passes and its remaining maturity shortens, it is valued at the lower yield applying to that shorter maturity, producing a price gain in addition to the coupon. The return comes from the shape of the curve rather than from any change in it. The gain is realised only if the curve stays broadly where it is, so the position depends on rates not rising by more than the cushion the slope provides, and it must be rolled into a longer bond periodically to maintain the exposure.

router logicStocksCrypto

Router logic is the set of rules inside a smart order router that decides where and how to send each part of an order across competing trading venues. Inputs typically include displayed prices and sizes, the fees or rebates each venue charges, the probability of a fill, expected latency, historical fill quality and any regulatory obligation to respect protected quotations. The logic then slices and sequences child orders across lit books, auctions and dark venues. Because those choices affect execution price and information leakage, best execution rules require firms to be able to explain and evidence how their routing serves the client.

rate of return regulationStocks

Rate of return regulation sets the prices a monopoly utility may charge so its revenues cover operating costs plus an allowed return on the capital it has invested. The regulator determines a rate base of assets, an allowed rate of return and the costs it will accept, then approves tariffs expected to produce that outcome. Its weakness is the incentive it creates: efficiency savings reduce allowed revenue while capital spending increases the rate base, so the firm has reason to over-invest and little reason to cut cost. Price cap regulation was developed to address that by fixing allowed price changes for a period regardless of realised cost.

Resolution Trust Corporation (RTC)Stocks

The Resolution Trust Corporation was the United States government body created in 1989 to resolve savings and loan associations that had failed, taking over their assets and disposing of them. It closed or sold hundreds of institutions and sold vast quantities of real estate and loans, developing techniques such as bulk auctions, equity partnerships with private investors and early large-scale securitisation of commercial mortgages to shift illiquid assets at scale. Its work ended in the mid-1990s, with remaining responsibilities passing to the Federal Deposit Insurance Corporation. It remains the standard reference for a public asset management company handling a systemic banking clean-up.

rights issueStocks

A rights issue raises new equity by offering existing shareholders the chance to buy additional shares in proportion to their holdings, usually at a discount to the market price, within a defined period. The right itself has value, so shareholders who do not wish to subscribe can normally sell it in the market and receive compensation for the dilution instead. Because every holder gets the opportunity, the structure respects preemption rights, which is why it is the standard method for substantial equity raising in the United Kingdom and much of Europe. Underwriters usually agree to take up shares that are not subscribed.

Rate of Capital GainStocks

The price appreciation component of an investment's return over a period, calculated as the ending price minus the beginning price, divided by the beginning price. Added to the income yield, which is dividends or coupons divided by the beginning price, it gives the total holding period return. Separating the two matters because they can be taxed differently and because a holding can pay a positive income yield while its price component is negative.

Realized Compound ReturnStocks

The annualized rate actually earned on a bond over a holding period, calculated from the final accumulated value including coupons reinvested at the rates that really prevailed, rather than at the yield to maturity. Yield to maturity assumes every coupon is reinvested at that same yield, so the two figures diverge whenever rates change. The gap is the reinvestment risk a bondholder carries, and it grows with the size of the coupon.

Registration StatementOptionsStocks

The disclosure document a company files with the United States Securities and Exchange Commission before offering securities to the public, containing audited financial statements, a description of the business, risk factors, the use of proceeds and details of the offering. The prospectus given to investors forms part of it. Sales cannot be completed until the filing is declared effective, and the commission reviews and comments rather than approving the merits of the offering.

Regulatory ArbitrageStocksCrypto

Structuring an activity so it falls under the least costly set of rules while its economics stay largely unchanged, for example booking business in a lighter-touch jurisdiction, reclassifying an instrument into a category carrying a lower capital charge, or moving lending outside the regulated banking perimeter. It exploits the fact that rules attach to legal form as well as substance. Regulators respond with substance-over-form tests, consolidated supervision and cross-border coordination.

ReinsuranceStocks

Insurance bought by an insurer from another insurer to transfer part of the risk it has underwritten. Treaty reinsurance covers a whole class of business automatically, while facultative reinsurance is negotiated risk by risk. Proportional forms share premiums and losses in a fixed ratio, and excess of loss forms respond only above an attachment point. Ceding risk lets an insurer write larger policies, smooth results, protect capital against catastrophes and free capacity for new business.

Replicating PortfolioOptionsStocks

A combination of the underlying asset and borrowing or lending that produces exactly the same payoff as a derivative in every future state considered. If such a portfolio exists, the derivative must cost what the portfolio costs, because any difference would allow a trade with certain profit. Option pricing models are built this way: the binomial method solves for the number of shares and the loan that match the option's payoffs, then rebalances at each step.

RepossessionStocks

A secured lender taking back the specific asset pledged as collateral after the borrower defaults, most commonly a vehicle or equipment. The security agreement and local law set what notice is required, whether a court order is needed, and how a peaceable seizure may be carried out. The lender then sells the asset, applies the proceeds against the balance and costs, and can usually pursue the borrower for any deficiency that remains.

Residual ClaimStocks

A claim on a company's cash flows and assets that ranks after every fixed obligation has been met. Common shareholders hold it: they receive dividends only when declared and only after interest, taxes and preferred dividends are paid, and in a liquidation they receive whatever remains once creditors are satisfied, which is often nothing. The payoff is open-ended on the upside and bounded below at zero by limited liability.

Riding the Yield CurveStocks

Buying a bond with a maturity longer than the intended holding period and selling it before it matures, so that as it ages it is valued at the lower yield attaching to shorter maturities. On an upward sloping curve that roll down produces price appreciation on top of the coupon. The extra return is not assured: if yields rise or the curve flattens during the holding period, the position can return less than a matched-maturity bill.

Risk Structure of Interest RatesStocks

The pattern of yields on bonds that share the same maturity but differ in default risk, liquidity and tax treatment. The spread of a corporate bond over a government bond of identical maturity compensates for expected default losses, for the uncertainty around them, and for thinner trading. Tax status works the other way, which is why municipal issues can yield less than Treasuries of the same term for investors in higher brackets.

Random VariableCrypto

A quantity whose value is determined by the outcome of a random process, formally a function mapping each possible outcome to a number. It is described by a distribution giving the probability of each value or range, from which summary measures such as the mean, variance and quantiles are computed. A discrete one takes countably many values; a continuous one takes any value in a range and is described by a density. Asset returns, default indicators and claim amounts are all modelled this way.

Receiver SwaptionOptionsStocks

An option to enter an interest rate swap as the fixed-rate receiver and floating-rate payer, at a strike rate agreed at the outset. It gains value when swap rates fall below the strike, since the holder can then receive the higher agreed fixed rate, so it behaves like a put on rates and a call on bond prices. Investors use it to lock in a reinvestment rate on cash expected in future, and it is the option an issuer effectively holds inside a callable bond.

Reciprocal RateStocksFutures

The exchange rate for a currency pair expressed the other way round, obtained by dividing one by the quoted rate. If one currency is quoted at 1.25 units per unit of another, the reciprocal quote is 0.80 in the opposite direction. Dealers use it to move between quoting conventions, and because bid and offer swap places when a quote is inverted, the bid of one becomes the reciprocal of the offer of the other. Careless inversion of a two-way price therefore produces the wrong spread.

ReconciliationStocks

The control process of comparing two independent records of the same balance or activity and investigating every difference until it is explained or corrected. In investment operations it covers positions and cash held at the custodian against the accounting system, trade records against broker confirmations, and fund units in issue against the register. Differences are classified as timing items that will clear or as genuine breaks needing correction, and unresolved breaks are escalated because they can conceal errors, unauthorised activity or misappropriation.

RefinancingStocks

Replacing existing debt with new debt, with the same lender or a different one, so the old obligation is repaid out of the proceeds of the new one. Borrowers do it to extend maturity, lower the interest rate, switch between floating and fixed, release collateral or relax covenants. The economics turn on whether the saving over the remaining term exceeds the cost, including prepayment penalties, arrangement fees and writing off unamortised issue costs. Mass refinancing when rates fall is what shortens the life of mortgage-backed securities.

RegulatorStocks

A public authority with statutory powers to authorise firms, make rules for their conduct and prudential soundness, supervise compliance and take enforcement action. Powers typically include granting and withdrawing permission to operate, compelling information, imposing fines, restricting business lines and pursuing individuals. In financial services, responsibility is often split between a body overseeing the stability of firms and one overseeing conduct toward customers and markets, with securities issuance and disclosure supervised separately depending on the jurisdiction.

Relationship ModelStocks

A description of corporate governance systems in which companies are financed and monitored through long-term relationships with banks, suppliers and cross-holding partners rather than through liquid capital markets. Control sits with insiders holding large stakes and board seats, ownership is concentrated, disclosure is lighter, and hostile takeovers are rare. It is contrasted with the market-based or outsider model of the United States and United Kingdom, where dispersed ownership, extensive disclosure and the market for corporate control supply the discipline instead.

Race to the BottomStocks

Competition between jurisdictions or firms that progressively lowers standards, taxes, wages or regulatory requirements as each tries to attract capital or undercut rivals. Each move is individually rational but the collective outcome leaves everyone worse off on the dimension being cut, since the relative advantage disappears once others follow. It is invoked in debates about corporate tax competition, labour and environmental rules, and it is the argument for coordinated minimum standards.

Rate-and-Term RefinanceStocks

Replacing an existing mortgage with a new one that changes the interest rate, the repayment period, or both, without withdrawing meaningful equity. The new loan pays off the old balance plus closing costs, and cash back to the borrower is capped at a small amount set by the loan programme. Because no equity is taken out, lenders generally price it below a cash-out refinance. The economics turn on closing costs relative to the monthly saving and how long the loan is held.

Rational Choice TheoryOptionsStocks

A framework assuming that individuals hold ordered preferences and select the option that best satisfies them given their information, the prices they face and their constraints. It supplies the optimising agent used in most microeconomic models and yields testable predictions about how behaviour shifts when relative prices or budgets change. Behavioural research documents systematic departures such as reference dependence, present bias and framing effects, which motivated bounded rationality models.

Rational Expectations TheoryStocks

The proposition that people form forecasts using all available information and an understanding of how the economy actually works, so their errors are random rather than systematic. Applied to macroeconomics it implies that policy changes the public anticipates are largely offset by adjusted behaviour, and that only surprises move real output. It reshaped models of inflation and central bank credibility, and underlies the argument for transparent policy rules over discretion.

ReaganomicsStocks

The economic programme of the Reagan administration in the 1980s United States, built on four elements: cuts in marginal income tax rates, slower growth in non-defence federal spending, deregulation of industries such as transport and finance, and support for tight monetary policy to break inflation. Supporters credit it with the disinflation and expansion that followed, while critics point to widened deficits. It is the most widely cited application of supply-side economics.

RealStocksCrypto

In economics, a value adjusted for changes in the general price level, as opposed to nominal, which is measured in the currency of the day. A real figure is computed by deflating the nominal one by a price index such as the consumer price index or the output deflator, so movement reflects purchasing power rather than inflation. Interest rates, wages and national output are all reported both ways, and comparisons across years use the adjusted series.

Real PropertyStocks

Land together with everything permanently attached to it, including buildings, fixtures, growing crops and mineral or air rights, plus the bundle of legal rights to use, exclude, lease and transfer it. It is distinguished from personal property, which is movable. The distinction determines which conveyancing formalities, recording rules, depreciation treatment and property tax rules apply, and it governs whether an item stays with a building when the building is sold.

Real TimeStocks

Data or processing delivered with no material delay between an event and its availability, so a quote, trade report or balance reflects the current state rather than a snapshot from minutes earlier. In markets, live feeds come directly from exchanges and usually carry a licence fee, while free displays are commonly delayed fifteen or twenty minutes. Systems that price, hedge or risk-manage positions depend on it because a stale input produces a stale decision.

Real wagesStocksCrypto

Wages measured in purchasing power rather than currency, calculated by dividing nominal pay by a consumer price index and rebasing to a reference year. The measure shows whether pay increases have outpaced the cost of what workers buy. They can fall while nominal pay rises if inflation is faster, which is why bargaining and policy discussions distinguish the two. Over long periods they track labour productivity, though the relationship is not one for one.

Recency, Frequency, Monetary Value(RFM) StocksCrypto

A customer scoring method that ranks each buyer on three variables: how recently they last purchased, how often they purchase, and how much they have spent. Each dimension is bucketed, usually into quintiles, and the combined score segments the base so marketing spend can be aimed at the segments most likely to respond. It is widely used in retail and subscription businesses because it needs only transaction history, no survey or demographic data.

Reference NumberStocks

A unique identifier a bank, card network or payment processor attaches to a transaction so it can be located later. It is generated when the transaction is authorised and appears on statements, receipts and confirmations. Customer service and dispute processes use it to retrieve the exact record rather than searching by amount and date, and a chargeback or trace request normally cannot proceed without it. It identifies the transaction, not the account holder.

RegulationStocks

A rule with the force of law issued by a government agency under authority delegated by legislation, setting out how the statute applies in practice. In finance, agencies such as securities commissions, banking supervisors and market authorities write rules covering disclosure, capital, conduct, custody and market operation, usually after publishing a proposal and considering public comment. Breach can bring fines, licence conditions or enforcement action, so compliance is a real operating cost.

Regulation WStocks

A Federal Reserve rule implementing sections 23A and 23B of the Federal Reserve Act, which limit transactions between a bank and its affiliates. It caps credit extended to any one affiliate and to all affiliates combined as a share of the bank's capital, requires collateral for covered exposures, and demands terms at least as favourable to the bank as those available from an unaffiliated party. The aim is to stop an insured bank subsidising riskier group companies.

Relief RallyStocks

A rise in prices that follows the removal of an anticipated threat rather than an improvement in fundamentals, for example when an economic release, court ruling, earnings report or policy decision proves less damaging than feared. Positioning drives much of the move as hedges are unwound and short positions covered. Because the trigger is the absence of bad news, such rallies can fade quickly if underlying conditions have not actually changed.

RepatriableStocks

Describing funds or investment proceeds that may lawfully be converted and transferred back to an investor's home country. Whether a holding qualifies depends on the destination country's exchange control rules, the account type used and any tax clearance obtained. In India, for example, balances in a non-resident external account are freely repatriable while those in a non-resident ordinary account face annual limits and documentation. Non-repatriable funds must stay in the local jurisdiction.

Required reserve ratioStocks

The minimum fraction of a bank's deposit liabilities that a central bank obliges it to hold as reserves, either as vault cash or as a balance at the central bank. Raising it forces banks to hold more against each unit of deposits, reducing what can be lent and lowering the deposit multiplier, while lowering it does the reverse. Several central banks have set the requirement to zero and now steer credit conditions through the interest paid on reserves instead.

Reserve RatioStocks

The share of a bank's deposit liabilities actually held as reserves, meaning vault cash plus balances at the central bank, expressed as reserves divided by deposits. It includes both the portion a regulator requires and any excess a bank chooses to keep for settlement needs or precaution. A higher figure means less of each deposit is lent out, which reduces the money multiplier. In insurance the same phrase describes funds set aside relative to premiums or claims.

RestatementStocks

A revision and reissue of financial statements a company has already published, made when the originals contained a material error, an accounting method was applied incorrectly, or a misstatement is discovered later. A revision corrects prior period figures in the comparatives, while a reissuance withdraws reliance on the earlier statements entirely. Restatements often trigger auditor and regulator scrutiny, covenant reviews and shareholder litigation, and they weigh on perceived reporting quality.

Retail Price IndexStocksCrypto

A United Kingdom measure of consumer price inflation compiled from a basket of goods and services. It differs from the consumer prices index mainly by including mortgage interest and certain housing costs, and by using a different mathematical formula to combine individual prices. Because that formula tends to produce a higher reading, the index lost its national statistic designation, though it remains embedded in index-linked gilts, some pensions and commercial contracts.

Retirement Income Certified Professional(RICP) Stocks

A professional designation awarded by The American College of Financial Services to advisers who complete coursework and examinations on retirement income planning, covering withdrawal strategy, Social Security claiming, annuity and pension choices, tax sequencing, health and long-term care funding, and estate issues. Candidates must meet experience and ethics requirements and complete continuing education to keep it. It signals training in decumulation rather than accumulation.

Return on RevenueStocks

A profitability ratio dividing net income by total revenue, showing how much profit a company keeps from each unit of sales. Because both figures come from the income statement, it isolates operating and cost efficiency without reference to the asset or capital base. Rising revenue alongside a flat or falling ratio indicates growth bought through discounting or higher costs. It is most useful compared against the same company over time or against direct competitors.

RevaluationStocksFutures

An official upward adjustment of a currency's fixed exchange rate against a reference currency or basket, made by the monetary authority. It makes imports cheaper and exports dearer in foreign currency terms, and is usually a response to inflationary pressure or a persistent external surplus. It is the opposite of devaluation and applies only under a pegged or managed regime, since a floating rate moves without an official act. In accounting the word means restating an asset to current fair value.

Revenue Agent's ReportStocks

A document an Internal Revenue Service examiner issues at the close of an audit, itemising each proposed adjustment, the legal basis for it, and the resulting change in tax, penalties and interest. The taxpayer may agree and sign, or dispute it by requesting an appeals conference within the stated period. If no agreement is reached, the Service issues a statutory notice of deficiency, which is what allows the taxpayer to petition the Tax Court.

Revenue per Available Seat Mile(RASM) StocksCrypto

An airline productivity measure equal to operating revenue divided by available seat miles, where an available seat mile is one seat flown one mile whether or not it was occupied. It captures both how full aircraft are and what fares were achieved, so it can be compared against cost per available seat mile to see whether a route or a network covers its unit costs. Carriers report it alongside load factor and yield.

Revenue per EmployeeStocks

A productivity ratio dividing total revenue by the average number of full-time equivalent staff over the same period. It indicates how much output each worker supports and is used to compare firms within an industry and to track whether a company is scaling revenue faster than headcount. Comparisons across industries are not meaningful because capital intensity and outsourcing differ, and heavy use of contractors can flatter the figure by keeping workers off the payroll count.

Revocable BeneficiaryStocks

A beneficiary designation on a life insurance policy or annuity that the owner can change at any time without the beneficiary's consent. It is the default for most policies and preserves the owner's flexibility as circumstances change. The opposite, an irrevocable designation, gives the beneficiary a vested interest that cannot be altered, borrowed against or surrendered without their agreement, which is why it appears in divorce settlements and collateral assignments.

Revolving creditStocks

A borrowing facility with an approved limit that the borrower can draw, repay and redraw without reapplying, such as a credit card, an overdraft or a corporate revolving loan. Interest accrues only on the drawn balance, and repaying restores availability. Corporate facilities usually carry a commitment fee on the undrawn portion and covenants the borrower must meet at each drawdown. Because the limit is a binding promise to lend, banks hold capital against the undrawn amount too.

Risk ControlStocksCrypto

The set of measures applied to reduce the likelihood or the size of a loss once risks have been identified and measured. In portfolio management it covers position limits, diversification rules, stop levels, leverage caps, liquidity buffers and hedges. In operations it covers segregation of duties, authorisation limits and system controls. It differs from risk financing, which pays for losses through insurance or reserves rather than preventing them.

Robber BaronStocks

A pejorative label for late nineteenth century American industrialists who built dominant positions in railways, steel, oil and finance through aggressive tactics including preferential rebates, predatory pricing, pooling arrangements and political influence. The term frames their wealth as extracted through market power rather than earned through efficiency. Public reaction to their combinations produced the Sherman Act of 1890 and the regulatory agencies that followed.

Rogue TraderStocksCrypto

An employee who takes positions well beyond authorised limits and conceals them, usually by falsifying records, exploiting weak reconciliation between front and back office, or booking offsetting fictitious trades. Losses stay hidden while positions are doubled up in hope of recovery, so the eventual loss far exceeds the original breach. Cases such as Barings in 1995 and Societe Generale in 2008 drove requirements for segregation of duties, independent confirmation and mandatory leave.

Rule of 70Stocks

A shortcut for estimating how long a quantity growing at a constant percentage rate takes to double: divide seventy by the growth rate expressed in percent. Something growing at two percent a year doubles in roughly thirty five years. It derives from the natural logarithm of two, about 0.693, and is accurate for small rates, with error widening as rates rise. It is applied to population, real output and the erosion of purchasing power by inflation.

Rent-a-CaptiveStocksCrypto

An arrangement in which a company buys access to an existing captive insurance vehicle owned by a sponsor instead of forming and capitalising its own. The participant rents a segregated cell or account within the sponsor's captive, funds it with premium and collateral, and keeps the underwriting result attributable to its own risks, while the sponsor supplies the licence, capital base and administration. It suits organisations whose premium volume is too small to justify the cost of a standalone captive, and the participant's exposure is normally ring-fenced from the other cells by contract or by protected cell legislation.

RescissionStocksCrypto

The cancellation of a contract that returns both parties to the position they held before it was made, with money and property handed back rather than damages paid. In securities work it most often appears as a rescission offer: an issuer that sold interests in a transaction failing to comply with registration or disclosure requirements offers to buy them back at the original price plus interest, limiting the liability that would otherwise arise. Statutory rescission rights are created by the governing securities or consumer credit law and usually run for a defined period after the transaction.

Residual RightStocks

The right to decide how an asset is used in circumstances the contract does not cover. Contracts cannot anticipate every future state, so ownership in the economic sense is often defined as holding whatever decision rights are left once the explicit contractual promises are exhausted. The idea underpins the property rights theory of the firm: whoever holds residual control has the incentive to invest in the asset, which is why allocating these rights matters in joint ventures, franchising and buyout structures. Residual claims on cash flow, such as common equity, are the financial counterpart.

Residual ValueStocks

The estimated worth of an asset at the end of a defined holding period, lease term or depreciation schedule. In lease pricing it sets the amount the lessee is charged for: the payment stream covers the difference between the starting value and the projected residual, plus a finance charge, so a higher assumed residual lowers the payment and shifts more risk onto the lessor. In depreciation accounting the same figure is the salvage value subtracted from cost before the depreciable amount is spread over the asset's useful life.

RestitutionStocks

A remedy requiring a party to give up a gain obtained at another's expense, measured by what the wrongdoer received rather than by what the claimant lost. Securities and commodities regulators commonly seek it alongside civil penalties, ordering a firm to repay customers money taken through unsuitable sales, unauthorised trading or misrepresentation. Because the measure is the benefit conferred, restitution can be ordered where the claimant cannot prove a precisely quantified loss, and it differs from disgorgement, which strips ill-gotten gains and may direct them to the regulator rather than to identified victims.

Retrospective RatingStocks

A premium method in which the final cost of an insurance policy is calculated after the period ends, using the buyer's own claims experience during that period. The insured pays a provisional premium up front, then the premium is recomputed from actual incurred losses plus loss adjustment expense and insurer charges, subject to a stated minimum and maximum. It converts part of the arrangement into self-funding: good loss experience produces a refund, poor experience produces an additional call, and the stated maximum caps how far that additional call can go.

Returned CheckStocks

A cheque the paying bank refuses to honour and sends back through the clearing system unpaid. The usual reasons are insufficient funds, a closed or frozen account, a stop payment instruction, a mismatched signature or a stale date. The depositing bank reverses the provisional credit it gave, so a balance that appeared available can disappear days after the deposit, and both banks typically charge a fee. In an investment account a returned deposit can unwind a purchase made against that provisional credit, leaving the customer responsible for any market loss in between.

Risk MarginStocksCrypto

An explicit addition to the best estimate of insurance liabilities, representing the compensation a third party would require to take those obligations over. Solvency II and IFRS 17 both build technical provisions as a best estimate plus this margin, and the standard method is a cost of capital calculation: project the capital that would have to be held against non-hedgeable risk in each future year, charge a prescribed cost of capital rate on it, and discount the result back. It makes the balance sheet value of liabilities transfer-based rather than purely statistical.

Risk Seeking(risk loving) StocksCrypto

A preference structure in which a decision maker accepts a gamble over a certain amount of equal expected value, so no premium is demanded for bearing variability and something is paid instead for the chance of an extreme outcome. In expected utility terms the utility function is convex, so the certainty equivalent exceeds the expected value. Prospect theory finds the pattern most often in the domain of losses, where people reject a certain loss in favour of a gamble that might avoid it, and in demand for lottery-like payoffs such as deep out of the money options.

Rational ExpectationsOptionsStocks

A modelling assumption that people form forecasts using all available information and the true structure of the economy, so their expectations are correct on average and their errors are unpredictable rather than systematically biased. It does not require anyone to be right in any single period, only that mistakes do not repeat in a way that could be exploited. The assumption underpins the efficient market hypothesis and much of modern macroeconomics: if households and firms anticipate a policy change, its effects are reflected in prices and behaviour before it takes effect.

Regional PolicyStocks

Government measures aimed at reducing economic disparities between areas within a country or trading bloc, typically by directing investment, grants, tax reliefs or infrastructure spending toward places with weaker output or higher unemployment. Instruments include enterprise zones carrying reduced business taxes, relocation incentives, transport and broadband projects, and structural funds of the kind the European Union operates. For investors the relevance is that such programmes change the after-tax economics of locating assets, and property valuations in designated areas can depend on a programme's duration and on whether relief is clawed back.

Regulatory CaptureStocksCrypto

The outcome in which an agency created to police an industry ends up serving the interests of the firms it supervises rather than the public. It arises from the concentration of expertise and lobbying resources on the industry side, the movement of staff between regulator and regulated, and the diffuse nature of consumer interests, which gives no single household an incentive to counter-lobby. Symptoms include rules written around incumbents' existing practices, enforcement that favours settlements over structural change, and standards that raise the cost of entry for new competitors.

Risk-Neutral WorldStocksCrypto

A hypothetical setting used in derivative pricing in which every investor is indifferent to risk, so all assets are assumed to grow at the risk-free rate and expected payoffs are discounted at that same rate. It is a computational device rather than a claim about behaviour: moving from the real-world probability measure to the risk-neutral one changes the drift of the underlying while leaving its volatility unchanged, and the resulting price is the one that rules out arbitrage in the real world. Black-Scholes and binomial pricing both operate inside it.

Real Exchange RateStocksFutures

The nominal exchange rate adjusted for the price levels of the two countries, expressing how many units of the foreign basket of goods one unit of the domestic basket buys. It combines the nominal quote with the ratio of the two countries' price indices, so a currency can appreciate in nominal terms while depreciating in real terms if its domestic inflation is lower. It is the measure relevant to competitiveness and to purchasing power parity, since trade responds to the relative prices of goods rather than to the nominal quote alone.

Registered BondStocks

A bond whose owner is recorded in a register maintained by the issuer or its agent, so interest and principal are paid to the person named rather than to whoever presents the instrument. It contrasts with a bearer bond, where possession is title. Registration may cover principal only or both principal and interest, and modern issuance is effectively all registered and held in book entry form within a depository. Transfer requires an instruction to the registrar, which is what allows tax reporting and makes a lost holding replaceable.

Return on CapitalStocks

A profitability measure comparing operating profit against the capital employed to produce it, showing how much a business earns on the money invested in it regardless of how that money was raised. The numerator is usually operating profit after tax and the denominator the sum of debt and equity funding, or equivalently net working capital plus net fixed assets. Comparing it against the weighted average cost of capital is the test of whether growth creates value, since expanding a business earning less than its cost of capital destroys value faster the more it grows.

Risky AssetStocks

An asset whose return is not known in advance, so its future value is a distribution rather than a single number. The classification is relative to a stated horizon and unit of account: a Treasury bill maturing at the horizon is risk-free in nominal terms over that period but risky in real terms if inflation is uncertain, and risky to a foreign investor because of the exchange rate. Portfolio theory treats the choice between risky assets and the risk-free asset as separate from the choice among risky assets themselves.

Rate LockStocks

A lender's commitment to hold a quoted mortgage interest rate for a stated number of days while the loan is processed, so the borrower is protected if market rates rise before closing. Locks carry an expiry, may cost a fee or a slightly higher rate for longer periods, and usually require a paid extension if the transaction runs late. From the lender's side the promise creates an interest rate exposure between commitment and funding, which is why pipelines of locked loans are hedged in the forward mortgage market.

Rate MakingStocks

The actuarial process of setting insurance premium rates so that expected claims, expenses and a provision for profit and contingencies are covered. Actuaries group policies into classes with similar expected loss, estimate frequency and severity from historical experience adjusted for trend and for changes in cover, then load the resulting pure premium for expenses and the cost of capital. In many jurisdictions filed rates must be shown to the regulator to be adequate, not excessive and not unfairly discriminatory before use.

Rate on LineStocks

The premium charged for a reinsurance layer expressed as a percentage of the limit of cover in that layer, calculated as premium divided by limit. A layer providing 50 million of cover written for 5 million of premium has a rate of 10 percent, and the reciprocal of that figure, the payback period, implies ten loss-free years would be needed to fund one full loss. Underwriters use it to compare layers of different sizes and to judge how the market is pricing remote risk.

Ratio SwapOptionsStocks

An interest rate swap in which the notional amount on one leg is a multiple of the notional on the other, so the two sets of payments do not offset one for one. A counterparty might receive fixed on one unit of notional while paying floating on two, which turns the trade into a leveraged view on the direction of rates rather than a hedge. The multiplier magnifies both the cash flows and the mark-to-market swing, making the position's rate sensitivity larger than the stated notional suggests.

Real Option AnalysisOptionsStocks

A capital budgeting method that values managerial flexibility by treating choices such as expanding, delaying, abandoning or switching a project as options on the underlying business. Instead of committing to a single discounted cash flow forecast, the analyst models the uncertainty in project value and prices the right to act once it resolves, using binomial trees, simulation or closed-form option formulas. The result adds a flexibility premium to conventional net present value, and it matters most where uncertainty is high and the decision can genuinely be deferred.

Redemption DateStocks

The date on which a bond's principal becomes repayable and the security is retired. For a bullet issue it coincides with maturity, but callable and sinking fund bonds have several possible earlier dates, and the first one the issuer can choose often drives pricing when the bond trades above par. Yield quotations state which date is assumed: yield to maturity uses the final one, yield to call the first optional one, and yield to worst whichever produces the lowest return for the holder.

Reference IndexOptionsStocks

The index a derivative, structured note or fund uses to determine payments or to define its objective. The contract specifies which version applies, price or total return, who calculates it, how values are observed, and what happens if it is discontinued or materially changed. Because the index is chosen rather than negotiated, its own rules on constituent selection, weighting and rebalancing become part of the instrument's economics, so a change in methodology can shift the payoff without any change to the contract itself.

Refunding ProtectionStocks

A bond covenant barring the issuer from redeeming early with money raised from cheaper new debt, even where a general call right exists. It targets the specific event bondholders most dislike, refinancing at lower interest rates, while still permitting calls funded from operating cash flow or asset sales. Protection usually runs for a stated number of years from issue. A bond described as non-refundable may therefore still be callable, and that distinction changes how the call risk is priced.

Regulatory HarmonizationStocksCrypto

The process of aligning rules across jurisdictions so firms face comparable requirements wherever they operate. It ranges from mutual recognition, where one authority accepts another's supervision, through common minimum standards such as the Basel capital framework, to identical texts adopted region-wide. The aims are to cut duplicate compliance cost and to close gaps that let activity migrate to the least demanding regime. Differences in timing and in national add-ons mean harmonized standards rarely produce identical outcomes in practice.

ReinstatementStocks

The restoration of insurance cover to its original amount after a claim has eroded it, or the revival of a policy that has lapsed. In excess of loss reinsurance the contract states how many reinstatements are available and at what price, often a pro rata premium based on the portion of the limit used and the time remaining in the period. Without one, a layer is exhausted once paid, so the number purchased determines how many separate events the programme can absorb in a single year.

Reinsurance BrokerStocksCrypto

An intermediary that places an insurer's risk with reinsurers, structuring the programme, preparing the submission of exposure data, negotiating terms, and handling claims and accounting afterwards. The broker is normally paid a commission deducted from the reinsurance premium, so the buying insurer sees the cost embedded in the rate rather than as a separate fee. Beyond placement these firms supply catastrophe modelling and market pricing information, which makes them a main source of the analytics used to set retentions and layer limits.

Reinsurance PoolStocks

An arrangement in which several insurers share a defined class of risk by ceding premiums and losses into a common account, each member taking an agreed percentage of the total. Pools are used where individual exposures are too large or too rare for one carrier to absorb, such as nuclear, terrorism or aviation risk, and where a national scheme requires participation. Each member's result then reflects the aggregate experience of the pool rather than the policies it wrote itself.

Reinsured(cedant, ceding company) Stocks

The insurance company that transfers part of the risk it has underwritten to a reinsurer, also called the cedant or ceding company. It keeps the original contract with its policyholder and remains liable to that policyholder in full, so reinsurance changes who ultimately bears a loss without changing who owes the claim. It pays a premium, retains an agreed layer of loss for its own account, and may receive a ceding commission recognizing the acquisition costs it has already incurred.

RentesStocks

French government bonds paying a fixed annual income, issued historically as perpetual securities with no repayment date so the holder simply received the coupon indefinitely. The name comes from the rente, the income stream itself, and the price of such a security is the coupon divided by the yield investors require, which makes its value unusually sensitive to interest rates. Nineteenth century European finance was built around these instruments, and the word survives as the general French term for fixed income government stock.

RepatriationStocksFutures

The return of capital or earnings held abroad to the investor's home country, converting foreign currency back into the domestic one. Companies repatriate profits from overseas subsidiaries through dividends, intercompany loans or royalty payments, and the choice among those routes is shaped by withholding taxes, exchange controls and how the home country taxes foreign income. Large flows move currency markets because they concentrate demand for the home currency, so tax changes altering the cost of bringing money home can shift them sharply.

Reputational RiskStocksCrypto

The risk that damage to a firm's standing with customers, counterparties, employees or regulators reduces its future earnings or its access to funding. It is usually a consequence of another failure rather than a standalone event: a conduct breach, a data loss or a mispriced product first brings fines and remediation costs, then the slower loss of business. Because there is no position to measure, firms track it through complaint volumes, media monitoring, customer attrition and scenario analysis instead of through an exposure figure.

ResolutionStocks

A formal decision put to a vote at a company meeting and recorded in the minutes. Ordinary resolutions carry routine business such as approving accounts or reappointing auditors and pass on a simple majority of votes cast, while special resolutions cover constitutional changes such as amending the articles or reducing capital and require a higher threshold set by company law. Shareholders may also table their own, subject to notice and holding requirements, which is the main formal channel for raising governance concerns.

RetentionStocks

The portion of a risk an insurer or a self-insured company keeps for its own account instead of transferring it to a reinsurer or insurer. It can be expressed as a deductible per claim, an attachment point above which a reinsurance layer responds, or an aggregate amount for the year. Setting it trades premium against volatility: a higher figure lowers the ceded premium but leaves more loss inside the balance sheet, so the level is chosen against available capital and tolerance for earnings swings.

RetrocessionaireStocks

The reinsurer that accepts risk ceded by another reinsurer, standing one step further removed from the original policyholder. The chain runs from insurer to reinsurer to this counterparty, and each transfer passes on part of the exposure together with part of the premium. Because the same catastrophe exposure can circulate through several such contracts, supervisors monitor these chains for spiralling, where a company ends up indirectly reinsuring losses it had already ceded away and its net position is far larger than it believed.

Return PeriodStocks

The average interval between events at or above a given severity, used in catastrophe modelling to express how rare a loss is. A 250 year loss corresponds to an annual exceedance probability of one in 250, and the two figures are simply reciprocals of each other. It describes long run frequency rather than a schedule: an event of that size can occur in consecutive years, because each year carries the same probability regardless of what happened in the previous one.

Reverse Dutch AuctionStocksCrypto

An auction in which the buyer states the quantity it wishes to purchase and sellers submit offers, with the price rising until enough sellers are willing to transact. Companies buying back their own shares use the format: holders tender at prices within a stated range, and the company sets the single clearing price that secures the amount it wants, paying that price to everyone accepted. It reveals the supply curve of willing sellers instead of requiring the buyer to guess where it lies.

Reverse Knock-In OptionOptionsStocks

A barrier option that comes into existence only when the underlying reaches a barrier placed where the option is already in the money, rather than out of the money as in a standard knock-in. A reverse knock-in call has its barrier above the strike, so at the moment it activates it already carries intrinsic value. That discontinuity makes the payoff jump at the trigger, so the position is difficult to hedge near that level and its delta can change abruptly as the underlying approaches.

Reverse Knock-Out OptionOptionsStocks

A barrier option cancelled when the underlying reaches a barrier set in the region where the contract is in the money. A reverse knock-out call has its barrier above the strike, so the holder loses the option exactly when it has become most valuable and the payoff drops to zero at the trigger rather than tapering away. The premium is far lower than for a vanilla option of the same strike, and the sharp jump in value at the barrier makes the greeks unstable nearby.

Reverse Leveraged Buyout(reverse LBO) Stocks

The return of a company to public markets through a share offering after it was taken private in a leveraged buyout. Proceeds usually repay part of the acquisition debt, so the listing both raises equity and reduces balance sheet risk, while the sponsor keeps a stake and sells down over time under lock-up terms. Investors examining one compare the debt still outstanding, capital spending deferred during private ownership, and how much of the earnings improvement came from operations rather than leverage.

RibaStocks

The Arabic term for the increase or excess that Islamic law prohibits in financial dealings, understood most commonly as interest charged on a loan of money. The prohibition rests on the principle that a return must come from bearing risk in a real transaction rather than from lending money at a guaranteed increment. Islamic finance therefore structures funding around asset sale at a disclosed mark-up, leasing, or profit and loss sharing partnerships, with a supervisory board reviewing whether individual contracts comply.

RightsizingStocks

A corporate restructuring that resets headcount, facilities and business lines to the level management judges appropriate for expected demand, most often through reductions. The word is a management label for downsizing that emphasizes matching capacity to workload rather than cutting for its own sake. Accounts record the cost as a restructuring charge covering severance, lease exits and asset write-downs, and analysts separate that one-off charge from continuing operating expense when judging whether the promised savings are durable.

Risk MonitoringStocksCrypto

The continuing process of measuring exposures against limits and reporting breaches to the people able to act on them. It turns a risk framework into daily practice: positions are revalued, exposures aggregated across desks and counterparties, and metrics such as value at risk, stress losses, concentration and liquidity coverage compared with the limits the board approved. Its effectiveness rests on independence from the risk takers and on escalation rules stating who is told, how quickly, and what must happen next.

Roller Coaster(roller coaster swap) OptionsStocks

A swap or loan whose notional amount rises for a period and then falls, following the funding profile of an underlying project rather than staying level throughout. Construction and seasonal working capital deals use the structure because borrowing peaks partway through and then amortizes. Valuing it means treating each period's notional separately along the forward curve, so its sensitivity to interest rates is not comparable to that of a bullet swap of the same starting size.

Running BrokerStocksCrypto

A bill broker who buys bills of exchange from holders and places them with discount houses or banks, earning a turn on the difference rather than holding the paper on its own book. The role developed in the London discount market, where such brokers carried bills between institutions and matched sellers with buyers. Because the firm acts as intermediary rather than principal it takes little credit exposure itself, and its value lies in knowing which houses will accept which names.

RationalityStocksCrypto

The assumption in economic models that a decision maker holds consistent preferences and chooses the option that best satisfies them given the information and constraints faced. Consistency rather than selfishness is what the term requires: preferences must be complete and must not contradict each other when options are compared in different orders. Behavioural research documents systematic departures such as loss aversion and framing effects, which is why models increasingly use bounded rationality, where search and computation are themselves costly.

Real Balance EffectStocksCrypto

The change in spending that follows a change in the purchasing power of money holdings. When the price level falls, the real value of cash and fixed-value assets rises, households feel wealthier and buy more, pushing output back toward its earlier level without any change in interest rates. Named the Pigou effect after its originator, it was offered as an argument that a flexible price level could restore full employment unaided. Debt fixed in nominal terms works against it, since falling prices raise the real burden on borrowers.

Reversion LevelStocks

The long run value toward which a mean-reverting variable is pulled in a stochastic model. In a process of the form dx = a(b - x)dt + sigma dW, b is that level and a is the speed at which the gap closes, so the expected change is positive when the variable sits below it and negative when it sits above. Interest rate and volatility models depend on this structure because those quantities do not drift without limit the way an equity price can.

remaindermanStocks

The person or entity that receives property held in a trust or a life estate once the prior interest ends, typically on the death of the income beneficiary. A remainderman holds a future interest rather than a present right of use, so they cannot draw income or occupy the property while the life tenant lives, but they can object if the life tenant damages the asset. The interest can be vested, meaning certain to take effect, or contingent on a stated condition being met.

reversing tradeStocksFutures

A trade that closes an existing futures or options position by taking the equal and opposite position in the same contract, rather than holding it to delivery. A trader long ten contracts sells ten of the same contract, the clearing house nets the two, and the position and its margin obligation disappear. Most exchange-traded derivative positions are settled this way rather than by physical delivery, and the profit or loss is the difference between entry and exit prices multiplied by the contract size.

risk sharingStocksCrypto

An arrangement in which two or more parties agree in advance to divide the financial consequences of an uncertain event rather than one party bearing all of it. Insurance pools, reinsurance treaties, joint ventures with agreed loss splits and co-payments in a health plan are all forms of it. It differs from risk transfer, where the exposure moves wholly to another party, and from retention, where it is kept. Sharing lowers the variance each party faces, and the price is the premium or the share of upside conceded.

Revenue Anticipation Note(RAN) Stocks

A short-term municipal note issued in expectation of specific non-tax revenue, such as a state or federal grant reimbursement or utility receipts, and repaid when that revenue arrives. It smooths the gap between when a government must spend and when it is paid.

Rent Roll(tenant schedule) Stocks

A schedule listing every unit or suite in a property with its tenant, lease start and end dates, contract rent, concessions, deposits and occupancy status. It is the lease-level record a T-12 aggregates.
