J: Glossary Terms

J

jobless claimsStocksCrypto

Weekly counts of new applications for unemployment insurance and of people still receiving benefits, published in the United States by the Department of Labor. Because they arrive weekly rather than monthly, they are among the timeliest labor market indicators. Individual weeks are noisy, so a four-week moving average is the standard way to read the underlying trend.

JOLTSStocksCrypto

Job openings and labor turnover survey, a monthly Bureau of Labor Statistics report on the demand side of the United States labor market. It counts unfilled job openings on the last business day of the month, together with hires, quits, layoffs and discharges, and other separations. The quits rate is watched as an indicator of worker confidence and the ratio of openings to unemployed workers as a measure of labor market tightness. It is released with a longer lag than the payroll report.

Just-in-Time Liquidity(JIT liquidity) Crypto

Liquidity supplied immediately before a known or observed swap and withdrawn shortly after to capture fees, potentially diluting passive LP returns.

Jade LizardStocksOptions

A strategy combining a short put with a short call spread, typically structured for a net credit and no upside loss if the credit exceeds call-spread width.

Jensen's AlphaStocksCrypto

The intercept from a capital-asset-pricing-style regression, interpreted as return unexplained by the model's market beta under its assumptions.

Johansen TestStocksCrypto

A multivariate procedure for estimating the number of cointegrating relationships among multiple nonstationary time series.

Junk Bond(high-yield bond, junk bonds, high yield bonds) Stocks

A junk bond, or high-yield bond, is a corporate or government bond rated below investment grade by major credit rating agencies, reflecting a higher perceived risk that the issuer could default. To compensate investors for this added risk, junk bonds pay higher coupon rates and yields than investment-grade bonds of similar maturity. Their prices tend to be more sensitive to the issuing company's business and economic conditions than to interest-rate moves alone, giving them return characteristics that sit between investment-grade bonds and stocks.

Jelly Roll(Roll (options combination)) Options

A four-leg combination that pairs a synthetic long position in one expiration with a synthetic short position in another (same strikes, different expirations), isolating the cost of carry between the two expirations rather than taking a directional or volatility view.

job openings rateStocksCryptoOptionsFutures

A JOLTS metric measuring the number of unfilled job positions on the last business day of the month as a percentage of total employment plus job openings; used together with the unemployment rate (as the "job openings to unemployed" ratio) to gauge how tight or loose the labor market is.

Joint Brokerage AccountStocks

A taxable brokerage account owned by two or more people, most commonly spouses or partners, who share access to and legal ownership of the assets. Structures include joint tenants with rights of survivorship, where a deceased owner's share passes automatically to the surviving owner(s), and tenants in common, where each owner's share passes according to their estate plan instead. Full guide →

Joint Tenants(Joint Tenancy) Stocks

Joint tenants are two or more people who co-own an investment account or asset with equal, undivided shares. The most common form used for brokerage accounts, joint tenants with right of survivorship (JTWROS), automatically passes a deceased owner's share to the surviving joint tenant(s) outside of probate.

Joint Tenants with Right of Survivorship(JTWROS) Stocks

Joint tenants with right of survivorship (JTWROS) is a co-ownership structure in which each owner holds an equal, undivided interest in the account, and upon one owner's death their share automatically transfers to the surviving owner(s) without going through probate. It is the most common titling for brokerage accounts held by married couples or family members who want assets to pass directly to the survivor.

Japan ETFStocks

A Japan ETF is an exchange traded fund whose portfolio tracks Japanese equities, most often through a broad benchmark such as the TOPIX or the Nikkei 225, or through a size, sector or factor subset of that market. For an investor outside Japan the total return combines the local market move with the change in the yen against the home currency, which is why currency-hedged versions exist that use forward contracts to strip out the exchange rate component at a cost reflecting the interest rate differential.

Japanese Government Bond(JGB) Stocks

A Japanese government bond is yen-denominated debt issued by the Ministry of Finance of Japan across maturities from two to forty years, including inflation-linked and floating rate lines. The market is one of the largest in the world and is dominated by domestic holders, with the Bank of Japan itself owning a very large share as a result of sustained asset purchases and yield curve control. Because the central bank has actively managed the shape of the curve, JGB yields have at times reflected policy targets more than private market clearing levels.

Junior ISAStocks

A United Kingdom tax-advantaged savings and investment account held for a child under eighteen. A parent or guardian opens it, anyone may contribute up to an annual allowance set by HM Revenue and Customs, and returns are free of United Kingdom income and capital gains tax. The child can take over management of the account before adulthood but cannot withdraw until eighteen, when it converts into an adult ISA.

jewelryStocks

Jewelry as an investment category covers pieces valued above the melt value of their metal and the wholesale value of their stones because of design, maker, period, or provenance. Signed work from recognized houses, distinctive period styles, and pieces with documented ownership history trade at large premiums to intrinsic material value, while generic mass-market pieces trade close to scrap. Grading reports for significant stones plus original boxes and papers support price. The market is illiquid, retail markups are wide, and resale usually happens through auction or specialist dealers at a discount to retail.

Japan Credit Rating Agency(JCR) Stocks

Japan Credit Rating Agency is a Tokyo-based credit rating firm that publishes opinions on the creditworthiness of corporate, financial, sovereign and structured finance issuers, mainly in Japan and the wider Asian market. It assigns long-term and short-term ratings on lettered scales. It is registered with Japanese authorities and, in the United States, as a nationally recognized statistical rating organization, which allows its ratings to be used in certain regulatory contexts.

J-curveStocksFutures

The J-curve describes the path a country's trade balance follows after its currency depreciates: the balance worsens first and improves later, tracing a shape like the letter. The immediate effect is a price effect, because existing contracts and shipments already in transit are denominated in foreign currency, so imports cost more in domestic terms while export receipts have not yet changed. The volume effect arrives with a lag as buyers respond to the new relative prices, exports grow and imports are substituted, eventually turning the balance positive. Private fund investors borrow the same image for a fund's early negative returns as fees are drawn before investments mature.

jump processStocksCrypto

A jump process is a stochastic process whose path can move discontinuously, changing by a finite amount in an instant rather than only through small continuous increments. In asset pricing it is added to a diffusion to produce a jump diffusion model, where a Poisson-type arrival triggers a shock of random size. The reason is empirical: pure diffusion models cannot generate the fat tails and sudden gaps that returns actually show, and they price deep out of the money options too cheaply. Adding jumps produces a volatility smile naturally and makes perfect delta hedging impossible, because a jump cannot be neutralized by a position adjusted continuously.

jump-to-default(jump to default risk) Stocks

Jump-to-default risk is the exposure to an issuer failing suddenly, without the gradual spread widening that a model of continuous credit deterioration would predict. It matters most for positions that look hedged against small spread moves but are not hedged against a single discrete event: a portfolio delta-hedged for spread changes can still lose the full notional if the reference entity defaults overnight. Traders measure it as the profit or loss that would occur if a name defaulted immediately, given assumed recovery, and manage it by limiting single-name notional rather than by relying on spread sensitivity. Regulatory capital frameworks require a separate charge for it.

JobberStocks

The former principal dealer on the London Stock Exchange who quoted two-way prices to brokers and traded for their own account, but was barred from dealing directly with the public. Brokers acted as agents for investors and had to deal through them, an arrangement known as single capacity. The 1986 Big Bang abolished that separation, allowing firms to act as both broker and market maker, and the role was absorbed into the modern market maker.

Joint BondStocks

A bond on which two or more entities are jointly and severally liable for interest and principal, so a holder can demand full payment from any one of them rather than only a proportional share. The structure is used where affiliated companies, a parent and a subsidiary, or several municipalities finance a shared project. Credit quality reflects the combined capacity of the obligors, and the documentation must set out how they allocate the burden among themselves.

Jumbo LoanStocks

A mortgage larger than the conforming loan limit, so it cannot be bought or guaranteed by Fannie Mae or Freddie Mac and must be held by the lender or sold into the private market. The Federal Housing Finance Agency sets the limit annually and raises it in designated high-cost areas. Because there is no government-sponsored buyer standing behind it, underwriting is typically stricter on credit score, reserves and down payment, and pricing depends on the individual lender's appetite.

Jakarta Stock ExchangeStocksCrypto

The former equity exchange of Indonesia, which merged with the Surabaya Stock Exchange in 2007 to form the Indonesia Stock Exchange. Its benchmark, the Jakarta Composite Index, tracked all listed shares and is still quoted under that name. References to the Jakarta Stock Exchange in older research or fund documents point to what is now the Indonesia Stock Exchange, which runs the order book for Indonesian shares, bonds and derivatives and is supervised by the country's financial services authority.

Jerome KervielStocks

A trader at Societe Generale whose unauthorized positions in European equity index futures produced a loss of roughly 4.9 billion euros when the bank unwound them in January 2008. He had worked in the bank's back office before moving to the trading desk and used that knowledge to enter offsetting fictitious trades that concealed the size of his directional exposure from risk controls. The episode is taught in operational risk courses as an illustration of why trade confirmation, position reconciliation and segregation of duties are kept independent of the desk.

Jesse L. LivermoreStocksCrypto

An American speculator (1877 to 1940) known for large directional positions in stocks and commodities, including short exposure ahead of the 1907 panic and the 1929 crash. He began in bucket shops and later traded through brokers, working from tape reading, pivot levels and position pyramiding rather than company fundamentals. His methods were popularized in the 1923 book Reminiscences of a Stock Operator by Edwin Lefevre, written about a thinly disguised version of him. He was bankrupted more than once, which is why his record is studied as a lesson in risk control rather than as a method to copy.

Joint AccountStocks

An account held by two or more people, each able to transact on it. The registration decides what happens on death: joint tenants with right of survivorship pass the whole balance to the survivor outside probate, tenants in common leave each holder's share to their own estate, and community property registration follows state marital property law. Assets are generally reachable by creditors of any one holder, and tax reporting is issued under the primary holder's taxpayer identification number, so co-owners must allocate reported income between themselves.

Judgment LienStocks

A claim against a debtor's property created when a court judgment for money is recorded in the jurisdiction where the property sits. Once perfected it attaches to real estate, and in some states to personal property, giving the creditor a right to be paid from sale proceeds before the owner receives anything. It clouds title, so the debt usually has to be satisfied or released before a sale or refinance can close. Priority against mortgages and other liens generally follows recording date, and the lien lapses after a statutory period unless renewed.

Jumpstart our Business Startups Act(JOBS Act) Stocks

A United States law enacted in 2012 that eased securities registration and disclosure requirements for smaller companies raising capital. It created the emerging growth company category, which phases in certain reporting and auditor attestation obligations after an initial public offering, permitted confidential draft registration filings, lifted the ban on general solicitation in some private placements, raised the shareholder count that forces registration, and directed the Securities and Exchange Commission to write rules for equity crowdfunding and for a scaled public offering exemption. Dollar thresholds inside it are adjusted periodically by the regulator.

Jackson Hole Economic SymposiumStocks

The Jackson Hole Economic Symposium is an annual conference hosted by the Federal Reserve Bank of Kansas City in Wyoming, bringing together central bankers, finance ministers, academics and market economists around a chosen policy theme. It has no decision-making authority, but the papers presented and the keynote address by the Federal Reserve chair have repeatedly been used to signal shifts in the framework or stance of monetary policy, so markets watch the remarks closely for changes in tone.

January EffectStocks

The January effect is the claim that share prices, particularly of smaller companies, tend to rise more in January than in other months. The usual explanations are tax-loss selling in December that depresses prices and is reversed in the new year, portfolio window dressing by institutions ahead of year-end reporting, and the investment of year-end bonuses. Studies since the anomaly was publicized report a weakened or inconsistent effect, which is the pattern expected when a documented calendar anomaly becomes widely traded.

Japan Association of Securities Dealers Automated Quotation(JASDAQ) Stocks

The Japan Association of Securities Dealers Automated Quotation was Japan's over-the-counter market for shares in smaller and growth-stage companies, launched by the securities dealers association and later run as an exchange market. It offered lighter listing standards than the main board so young firms could raise equity earlier. It was absorbed into the Osaka Securities Exchange and, after the merger that formed Japan Exchange Group, its listings were folded into the Tokyo Stock Exchange growth segment.

Japan Inc.Crypto

Japan Inc. is a shorthand for the close coordination between Japanese government ministries, banks and large industrial groups that characterized the country's rapid postwar growth. It describes an economy in which the finance ministry and the trade ministry guided credit and industrial policy, main banks supplied patient funding to affiliated firms, and cross-shareholdings within keiretsu groups insulated management from hostile takeovers. The term is often used critically, and the model weakened after the asset price collapse of the early 1990s and subsequent governance reforms.

Jarrow Turnbull ModelStocks

The Jarrow-Turnbull model is a reduced-form approach to pricing credit risk in which default is treated as an unpredictable event arriving at a hazard rate, rather than as the moment a firm's asset value falls below its debt. Default intensity and a recovery rate are inferred from observed bond prices and credit spreads, and interest rate risk is modelled alongside them. Because it calibrates to market prices instead of unobservable balance sheet values, it is widely used to value credit default swaps and defaultable bonds.

JitneyStocksCrypto

Jitney describes an arrangement in which a broker without direct access to an exchange routes client orders through a member firm, which executes them and shares the commission. The practice itself is routine order handling, but the word carries a second and pejorative sense: trades passed back and forth between brokers to manufacture the appearance of volume or to move a quoted price. Activity of that kind is market manipulation and is prohibited by securities regulators and exchange rules.

Johannesburg Interbank Average Rate(JIBAR) StocksCrypto

The Johannesburg Interbank Average Rate is South Africa's benchmark short-term interest rate, calculated from the rates at which a panel of banks bid and offer negotiable certificates of deposit for standard tenors, with outliers trimmed before averaging. It is published by the South African Reserve Bank and is referenced in floating rate loans, swaps and other derivative contracts. As with other survey-based benchmarks, authorities have worked to replace it with a rate anchored in observed overnight transactions.

John BogleStocks

John Bogle (1929 to 2019) founded The Vanguard Group and launched the first index mutual fund available to retail investors in the United States in 1976. His central argument was arithmetic: because investors as a group hold the market, their collective return before costs equals the market return, so fees, turnover and taxes determine how much of it they keep. He built Vanguard as a mutual structure owned by its own funds, which aligned the manager with shareholders in driving costs down.

Julian RobertsonStocks

Julian Robertson (1932 to 2022) founded Tiger Management in 1980 and became one of the defining figures of the hedge fund industry. He ran a global long-short equity strategy built on deep fundamental research, buying companies he judged cheap against their prospects and shorting those he judged expensive. He closed the fund to outside money in 2000 after losses tied to his refusal to own inflated technology shares, and afterwards seeded a generation of managers who became known as the Tiger cubs.

Jumbo CDStocks

A jumbo certificate of deposit is a time deposit issued in a large minimum denomination, conventionally one hundred thousand dollars or more in the United States. Like any certificate of deposit it pays a fixed rate for a stated term and imposes a penalty for early withdrawal, but the larger size means the rate is often negotiable and, for institutional buyers, the instrument may be issued in negotiable form and traded. Deposit insurance covers balances only up to the limit set per depositor, per insured bank and per ownership category.

Jumbo PoolStocks

A jumbo pool is a Ginnie Mae mortgage-backed security assembled from loans originated by more than one lender, in contrast to a custom pool backed by a single issuer's loans. Pooling across issuers produces a larger and more geographically diverse collateral pool, which smooths prepayment behaviour and improves liquidity for investors. The underlying mortgages are government insured or guaranteed, and Ginnie Mae guarantees timely payment of principal and interest to holders. The structure is associated with the Ginnie Mae II program.

Jurisdiction RiskStocksCrypto

Jurisdiction risk is the exposure that arises from where an asset, counterparty or transaction is legally located, as distinct from the credit quality of the counterparty itself. It covers the possibility that local courts will not enforce a contract as written, that capital controls will block repatriation, that tax or ownership rules will change, or that the country appears on sanctions or money laundering watch lists. Lenders and investors price it into required returns, and banks weigh it when deciding where to book business.

journal entryStocks

A journal entry is the record of a single transaction in double-entry bookkeeping, listing the accounts debited and credited, the amounts, the date and a description. Debits must equal credits in every entry, which keeps the accounting equation in balance and makes many errors detectable. Entries are first recorded in a journal in date order and then posted to the individual ledger accounts that feed the trial balance and the financial statements. Adjusting entries recognise accruals, prepayments, depreciation and provisions at period end, and because they rest on management judgement they receive particular attention in an audit.

junior subordinated debtStocks

Junior subordinated debt ranks near the bottom of a company's capital structure, behind senior debt and behind other subordinated obligations, and ahead only of preferred and common equity in a liquidation. It usually carries long maturities, a right for the issuer to defer interest for a period without triggering default, and a higher coupon to compensate for those features. Banks and insurers have issued it because regulators allow instruments with loss-absorbing characteristics to count toward regulatory capital, and rating agencies may treat part of it as equity. Deferral and deep subordination mean recovery in a default is typically small.

Joseph SchumpeterStocks

An Austrian-born economist who lived from 1883 to 1950 and placed the entrepreneur and innovation at the center of economic growth. He argued that new products, methods and organizational forms displace incumbents in a process he called creative destruction, so that firm failures and recessions are part of how an economy renews its capital stock. His analysis of business cycles and of the entrepreneurial function underpins much modern research on technology, competition and productivity.

Japanese HousewivesStocksFutures

Market shorthand, often personified as Mrs Watanabe, for Japanese retail investors who borrow in a low-yielding domestic currency to buy higher-yielding foreign currencies and assets. The trade earns the interest differential while the exchange rate holds, and it became large enough that its unwinding was cited as a driver of sharp yen moves. The label describes a behaviour pattern rather than a defined group, and the underlying carry trade carries the risk that a sudden currency move erases years of accumulated interest.

Jekyll and HydeStocksCrypto

Market slang for a security, sector, or market that alternates between two starkly different personalities, trading calmly and predictably for stretches and then turning erratic and volatile without an obvious change in fundamentals. The phrase is descriptive rather than analytical, but the underlying pattern is real: volatility clusters, and instruments with concentrated ownership, thin liquidity, or embedded leverage can shift regime abruptly when one of those conditions changes.

John B. TaylorStocks

An American economist known for the Taylor rule, a formula published in 1993 that describes how a central bank's policy interest rate might respond to deviations of inflation from its target and of output from potential. The rule is a benchmark rather than a mandate: policymakers and analysts use it to judge whether a given policy setting looks tight or loose relative to a simple systematic response. He has also served in senior United States Treasury roles and written extensively on monetary policy rules and international finance.

Joint CreditStocks

A credit account for which two or more people apply together, so each is fully responsible for the entire balance rather than for a share of it. Lenders assess the combined incomes and credit histories, which can support a larger limit than either applicant alone. The account reports on every holder's credit file, so late payment damages all of them, and responsibility survives the end of a personal relationship until the account is closed or refinanced into one name.

Joint ReturnStocks

A United States federal income tax return filed by a married couple, or by a surviving spouse in limited circumstances, combining both spouses' income, deductions, and credits on one return. Filing jointly usually produces wider bracket thresholds and access to credits that married taxpayers filing separately lose entirely. The trade-off is joint and several liability: each spouse can be pursued for the whole tax, interest, and penalties on that return, unless relief such as innocent spouse relief is granted. Bracket thresholds are set annually by the IRS.

Joint-Stock CompanyStocks

A business owned by shareholders whose capital is divided into transferable shares, allowing ownership to change hands without dissolving the enterprise. The form emerged to fund ventures too large or too risky for one merchant, and it is the historical ancestor of the modern corporation. Liability is what varies: early joint-stock companies often left shareholders liable for the firm's debts, whereas the limited liability company that succeeded them caps each shareholder's loss at the amount invested.

Judgment ProofStocks

A description of a debtor against whom a court judgment could be obtained but not usefully collected, because the person has no attachable income or assets. Wages below garnishment thresholds, income from exempt sources such as certain benefits, and property covered by state exemptions all sit beyond a creditor's reach. The status is practical rather than permanent: the judgment remains valid, usually accrues interest, and can be enforced later if circumstances change, and creditors often renew judgments for exactly that reason.

Junior AccountantStocks

An entry-level accounting role responsible for recording transactions, maintaining ledgers, preparing reconciliations, processing payables and receivables, and assembling supporting schedules for month-end close. The work is supervised, with review by a senior accountant or controller before figures reach published statements. It functions as the training route through which a practitioner learns the entity's chart of accounts and control procedures, and progression usually depends on professional qualification alongside experience.

Junior MortgageStocks

A mortgage that ranks behind an existing loan secured on the same property, so in a foreclosure the senior lender is repaid in full before the junior lender receives anything. That subordinate position is why junior mortgages, including most home equity loans and second mortgages, carry higher interest rates than first mortgages. Priority is generally set by the order of recording, and a junior lender can lose its claim entirely if sale proceeds fall short after the senior debt and costs are covered.

JobbingStocks

Making a market in securities by quoting two-way prices and profiting from the spread and from turning over positions, rather than from commission. On the London Stock Exchange before the 1986 reforms, jobbers dealt only with brokers and were barred from dealing with the public, which enforced a separation between principal and agency roles known as single capacity. That system ended when firms were allowed to act in both capacities, and the function is now performed by market makers and electronic liquidity providers.

Jump-Diffusion ModelStocks

An asset price model that adds sudden discrete jumps, arriving randomly and with random size, to the continuous diffusion of a standard lognormal process. The jump component reproduces features that pure diffusion cannot: fat tails in short-horizon returns, and the steep implied volatility skew observed in short-dated options. Because jump risk cannot be removed by continuous hedging, the market is incomplete and pricing requires an assumption about how jump risk is compensated.

JStocksCrypto

A fifth letter appended to a Nasdaq ticker symbol to mark the security as a voting share, used when an issuer has more than one class outstanding and the market needs to tell them apart. Nasdaq's fifth-letter scheme assigns a specific meaning to each letter, with K marking a non-voting share, W a warrant, R a right, U a unit and Y an American depositary receipt. The voting designation is temporary, applied around a shareholder vote or a recapitalization and removed once the situation is resolved.

JackpotStocks

An informal term for an unusually large and largely unearned windfall, borrowed from gambling and applied to outcomes such as a small position in a company that is acquired at a large premium, or an early stake in a business that later lists. The framing is a warning as much as a description: results driven by a single extreme outcome say little about the process that produced them, and treating one as evidence of skill encourages concentration and overtrading. Analysts separate repeatable edge from a distribution with a rare, very large tail.

James H. ClarkStocks

An American computer scientist and entrepreneur who founded Silicon Graphics, co-founded Netscape Communications with Marc Andreessen, and later founded Healtheon, which became WebMD. Netscape's 1995 flotation is widely treated as the opening event of the dot-com period, because a company with minimal revenue reached a large market capitalization on its first trading day and set the template for growth-before-profit offerings that followed. He is cited in market history as an example of a founder creating value chiefly by repeatedly starting companies rather than by operating one over a long period.

Job LotStocksFutures

A futures contract smaller than the exchange's standard size, created so participants can take positions that do not fit a full contract. A grain contract quoted in five thousand bushel units, for example, may have a smaller companion covering a fraction of that. The reduced size lowers the cash value of one tick and lets a hedger match a position to an actual exposure, but such contracts usually trade less often, so bid-offer spreads are wider and large orders are harder to fill without moving the price. The phrase also describes an assorted parcel of goods sold as one unit.

Joint LiabilityStocks

An obligation shared by two or more parties under which a creditor may pursue any one of them for the entire amount, not merely for that party's share. The debtor who pays more than a proportionate share then has a right of contribution against the others, but collecting it is that party's problem rather than the creditor's. In the strictly joint form all obligors must be sued together, while joint and several liability lets the creditor choose. It appears in co-signed loans, partnership debts, guarantees and many tort judgments.

Joint Return TestStocks

One of the tests in United States tax law determining whether a person can be claimed as a dependent. A person generally fails it, and cannot be claimed, if they file a joint return with a spouse for the year. A narrow exception preserves the claim where the couple files jointly only to obtain a refund of withheld tax and neither would owe any tax on separate returns. The test operates alongside the relationship, age, residency and support tests, and every applicable test must be met before a dependent claim stands.

Joint SupplyStocks

A production relationship in which one process yields two or more outputs together, so the quantity of one cannot be changed without changing the others. Refining crude oil produces gasoline, diesel and other fractions in proportions set largely by the input and the equipment, cattle yield beef and hides, and gas wells produce liquids alongside methane. The consequence for prices is that a demand increase for one output raises supply of the others as a by-product, which can push their prices down even though nothing changed in their own demand.

Joint and Survivor AnnuityStocks

An annuity paying for as long as either of two people is alive, most often a retiree and a spouse. Payments usually continue at a reduced percentage after the first death, with the survivor level chosen at the outset, and the higher that percentage the smaller the initial payment, because the insurer expects to pay for longer. United States retirement plans subject to spousal protection rules must offer this form as the default for a married participant, and electing a single-life payout instead requires the spouse's notarized consent.

Joint-Life PayoutStocks

A payout election under which an annuity or pension pays until the last of two covered lives dies, rather than ending at the first death. The pure form keeps the payment level throughout, so the amount starts lower than a single-life payout on either person, because the expected payment period is longer. Variants reduce the payment after the first death or add a guaranteed number of years, and each adjustment changes the starting amount. The election is generally irrevocable once payments begin.

Joseph StiglitzStocks

An American economist awarded the 2001 Nobel Memorial Prize in Economic Sciences, shared with George Akerlof and Michael Spence, for work on markets with asymmetric information. His research showed that when one side of a transaction knows more than the other, outcomes such as credit rationing and adverse selection arise, so a market need not clear at a price and the competitive benchmark can fail. He served as chair of the Council of Economic Advisers and as chief economist of the World Bank, and has written extensively on inequality and globalization.

JournalOptionsStocks

In bookkeeping, the book of original entry, where each transaction is first recorded in date order with the accounts debited and credited and a short explanation. Entries are then posted to the ledger, which organizes the same information by account, so one record preserves chronology and the other preserves balances. A general journal handles non-routine items while specialized journals capture repetitive flows such as sales, purchases and cash. The record is the audit trail: it is what links a figure in a financial statement back to the underlying document.

Junior SecurityStocks

A security whose claim on a company's earnings and assets ranks behind other claims if the issuer is liquidated. The order of priority runs from secured debt through senior unsecured and subordinated debt to preferred shares and then common equity, so each layer ranks behind what sits above it and ahead of what sits below. Rank determines who receives anything in a bankruptcy once the assets are sold, which is why lower-ranking claims carry higher yields or higher expected returns as compensation and absorb losses first.

Just In Case(JIC) Stocks

An inventory and capacity strategy that deliberately holds buffer stock and spare capacity so a supply interruption does not halt production. It is the opposite of just in time, which minimizes inventory by having inputs arrive as needed and treats holding stock as waste. The trade-off is explicit: carrying buffers ties up working capital and risks obsolescence, but it protects revenue when a supplier fails, a port closes or demand spikes. Widespread supply chain disruption in the early 2020s pushed many manufacturers toward this approach for critical components.

James M. Buchanan Jr.StocksCrypto

An American economist awarded the 1986 Nobel Memorial Prize in Economic Sciences for developing the contractual and constitutional basis of economic and political decision-making. With Gordon Tullock he founded public choice theory, which applies the assumption of self-interested behaviour to voters, politicians and officials rather than treating government as a neutral corrector of market failure. His constitutional economics argued that the rules constraining fiscal and monetary decisions matter more than the individual decisions taken within them.

Jan TinbergenStocksCrypto

A Dutch economist who shared the first Nobel Memorial Prize in Economic Sciences in 1969 with Ragnar Frisch for developing and applying dynamic models to the analysis of economic processes. He built some of the earliest macroeconometric models of national economies, and formulated what is now called the Tinbergen rule: achieving a given number of independent policy targets requires at least that many independent policy instruments. He also developed the gravity model of bilateral trade flows.

January BarometerStocksCrypto

A market observation holding that the direction of a broad equity index in January predicts its direction for the remainder of the year. It rests on a limited number of annual observations, and because a full calendar year contains January, part of the measured correlation is mechanical. Tests over longer samples and in other markets find the relationship is not stable enough to treat as a forecasting rule, and calendar effects that become widely published tend to weaken once traders act on them.

Japanese Yen(JPY) StocksFutures

The currency of Japan, issued by the Bank of Japan and denoted by the ISO code JPY. It is one of the most heavily traded currencies and a major reserve currency, conventionally quoted as yen per one United States dollar, so a rising quote means a weaker yen. Long periods of low domestic interest rates made it a common funding currency for carry trades, in which investors borrow yen to buy higher-yielding assets, so it often strengthens sharply when those positions are unwound during market stress.

Jean-Baptiste SayStocks

A French classical economist of the early nineteenth century, best known for the proposition later summarised as Say's law: production generates the income that funds demand for other goods, so a general glut across all markets cannot persist even though a surplus in any one market can. He also gave the entrepreneur a central role, casting that person as the coordinator who combines land, labour and capital and bears the risk of the outcome, a function earlier classical writers had folded into capital.

Jerry A. HausmanStocks

An American econometrician at the Massachusetts Institute of Technology, known for the Hausman specification test. The test compares two estimators, one consistent under both a null and an alternative hypothesis and one efficient only under the null, and treats a statistically significant difference between them as evidence against the null. It is used routinely to choose between fixed effects and random effects in panel data and to detect endogeneity. He also worked on measuring the welfare effect of new goods in price indices.

Jobs and Growth Tax Relief Reconciliation Act of 2003(JGTRRA) Stocks

A United States federal statute that accelerated income tax rate reductions previously scheduled for later years and cut the rates applied to long-term capital gains and to qualified dividends, taxing the latter at capital gains rates rather than as ordinary income. It also expanded expensing limits for small business equipment purchases and temporarily raised the alternative minimum tax exemption. Its provisions carried expiry dates and were later extended and then modified by further legislation, so current rates come from those later acts.

John R. HicksStocksCrypto

A British economist who shared the 1972 Nobel Memorial Prize in Economic Sciences with Kenneth Arrow for contributions to general equilibrium theory and welfare economics. He formalised Keynes's argument as the IS-LM framework, in which goods market and money market equilibrium jointly determine output and the interest rate. He also developed the compensated demand curve and the substitution effect that carries his name, and the Kaldor-Hicks compensation criterion in welfare economics is partly his.

Joint Owned Property(jointly owned property) Stocks

Property held by two or more people at the same time, where the form of co-ownership determines what happens on death and how each owner may deal with their share. Joint tenancy with right of survivorship passes a deceased owner's interest automatically to the survivors and bypasses probate. Tenancy in common leaves each share to that owner's estate. Tenancy by the entirety, available to married couples in some jurisdictions, adds creditor protection. Titling therefore overrides a will for the asset concerned.

Joint VentureStocks

A business arrangement in which two or more parties commit resources to a specific project or activity while remaining separate entities in everything else. It can be incorporated as a new company owned by the participants, or purely contractual with no new entity formed. The agreement fixes the scope, each party's contribution, how profits and losses are shared, how decisions are made, and how the arrangement ends. It is used to enter a market where a local partner is required, to share the cost of a large asset, or to combine complementary technology.

Jordanian Dinar(JOD) StocksFutures

The currency of Jordan, issued by the Central Bank of Jordan and denoted by the ISO code JOD. It has been pegged to the United States dollar at a fixed official rate since the mid 1990s, which the central bank maintains by standing ready to buy and sell dollars against its foreign reserves. The peg imports United States monetary conditions, so domestic interest rates track dollar rates, and it removes exchange rate uncertainty for trade and remittance flows at the cost of an independent monetary policy.

Judicial ForeclosureStocks

A foreclosure carried out through a court action, in which the lender sues the borrower, proves the debt and the default, and obtains a judgment plus a court-ordered sale of the property. It is the required method in states whose mortgage law provides no power of sale, and it is slower and costlier than the non-judicial route. In exchange it produces a court record that can support a deficiency judgment for any shortfall between sale proceeds and the debt where state law allows one, and some states grant a statutory right to redeem after the sale.

Judo Business StrategyStocks

A competitive approach in which a smaller company avoids direct confrontation with a larger incumbent and instead turns the incumbent's own commitments against it. Tactics include moving into segments the leader will not enter without cannibalising existing revenue, adopting a business model whose economics conflict with the leader's cost base, and shifting competition to a dimension where the leader's scale is a liability rather than an advantage. The name comes from the martial art's use of an opponent's momentum.

Junior Capital PoolStocks

A Canadian listing structure that let experienced founders raise seed capital and list a shell company with no operating business, then complete a qualifying transaction acquiring a real business within a set period. Funds raised were restricted until that acquisition, and failure to complete it in time led to delisting or transfer to a lower tier. The programme originated in Alberta and was succeeded by the capital pool company programme on the TSX Venture Exchange, which follows the same two-stage design.

Junior EquityStocks

Shares ranking behind other equity in a company's capital structure, meaning they receive dividends only after senior classes are paid and recover in a liquidation only once every prior claim is satisfied. Common stock is junior to preferred stock, which is itself junior to all debt. The lower priority is compensated by the residual claim on profits above the fixed entitlements ahead of it and, in most structures, by the voting rights that preferred shares often lack.

Justified WageStocksCrypto

The pay level economic analysis says a role warrants given the value of the output the worker produces, the skills and training required, working conditions, and the going rate in comparable jobs, as distinct from what the worker is actually paid. In competitive labour market theory it corresponds to the marginal revenue product of labour, the extra revenue one more worker generates. Observed pay diverges from it because of search costs, bargaining power, information gaps, minimum wage law and non-wage compensation.
