The language of institutional alternatives.
A working reference for the terms used across hedge fund research, due diligence, and portfolio analytics — from alpha and drawdown to high-water marks and 13F filings.
13F Filing
Form 13F is a quarterly U.S. regulatory filing through which qualifying institutional investment managers disclose specified long positions in reportable securities.
Absolute Return
Absolute return is an investment’s gain or loss over a period without subtracting the performance of a market benchmark. An absolute-return objective usually seeks positive results across varied market conditions, often with an additional cash-based target and explicit loss constraints.
Accredited Investor
An accredited investor is a person or entity meeting criteria that permit participation in certain exempt securities offerings under a particular jurisdiction’s rules.
Accretion
Accretion is the gradual increase in a debt security’s carrying value or price toward the amount expected to be repaid. It commonly occurs when a bond is bought below par and its discount is recognized over time.
Active Management
Active management selects securities, sectors, factors, or asset weights with the aim of improving return or risk relative to a benchmark or objective.
Active Share
Active share measures the percentage of portfolio holdings that differs from a benchmark, based on absolute differences in security weights. It ranges from 0% for an identical portfolio to 100% for a portfolio with no overlapping long positions under the standard formulation.
Activist Investing
Activist investing builds an ownership stake and seeks changes in strategy, operations, capital allocation, governance, or ownership to increase value.
Adjusted EBITDA
Adjusted EBITDA starts with EBITDA and adds back or removes items that management or analysts consider unusual, non-operating, non-recurring, or not representative of ongoing performance. It is a non-GAAP measure whose definition varies by company and transaction.
Administrator
A fund administrator independently performs services such as NAV calculation, investor records, subscriptions, redemptions, accounting, and reporting under its agreement.
Advisory Fee
An advisory fee is compensation paid to an investment adviser for portfolio management, advice, or related services. It may be based on assets, a fixed amount, performance, or another disclosed arrangement.
Agency Bond
An agency bond is debt issued by a government agency or a government-sponsored enterprise. Its credit support varies by issuer and jurisdiction: some obligations carry an explicit sovereign guarantee, while others rely on the issuer’s own resources or an implicit market expectation of support.
Alpha
Alpha is the portion of an investment’s return that remains after accounting for the return associated with a benchmark or specified risk factors. It is commonly interpreted as value added by active decisions, although the result depends critically on the model and benchmark.
Alpha Decay
Alpha decay is the reduction in an investment signal’s expected excess return as time passes, capital adopts it, market structure changes, or information becomes reflected in prices.
Alternative Investments
Alternative investments are assets and strategies outside conventional long-only public stocks, bonds, and cash. They include private markets, hedge funds, real assets, commodities, and specialized credit or derivative strategies.
Amortization
Amortization is the scheduled reduction of a debt balance or the systematic recognition of a bond premium over time. In fixed income, the word can describe principal repayments or the accounting treatment of a security bought above par.
Anchoring Bias
Anchoring bias is excessive reliance on an initial number, forecast, price, or narrative when making or updating a judgment.
Annualized Return
Annualized return converts an investment result covering more or less than one year into an equivalent yearly compound rate. It allows periods of different lengths to be compared, but it does not show the path, variability, or actual return earned in each calendar year.
Arbitrage
Arbitrage seeks profit from inconsistent prices of identical or closely related claims, usually by buying the cheaper exposure and selling the richer one.
Asset Allocation
Asset allocation is the decision to divide a portfolio among broad investment categories, such as equities, bonds, cash, real assets, and alternative strategies. It sets the portfolio’s main sources of expected return, risk, liquidity, and diversification before individual securities are selected.
Asset Class
An asset class is a group of investments with broadly similar economic characteristics, legal claims, return drivers, and risk behavior. Common high-level classes include equities, fixed income, cash, real assets, and alternatives, although classifications vary by investor and purpose.
Asset Protection
Asset protection is lawful planning intended to reduce exposure of property to future claims and liabilities while respecting creditor, disclosure, tax, and insolvency law.
Asset-Backed Security
An asset-backed security is a debt instrument supported by cash flows from a pool of financial assets such as auto loans, credit-card receivables, equipment leases, or consumer loans.
Attribution
Performance attribution is the process of decomposing a portfolio’s return relative to a benchmark or objective into identifiable sources, such as asset allocation, security selection, factor exposure, currency, trading, and interaction effects.
AUM
Assets under management, or AUM, is the market value of investments that a manager oversees for clients or pooled vehicles at a stated date. The figure may include discretionary and non-discretionary mandates, leverage, uncalled commitments, or advisory assets depending on the definition used.
Availability Bias
Availability bias is judging likelihood or importance by how easily examples come to mind, often because they are recent, vivid, emotional, or widely reported.
Backtest
A backtest applies an investment rule or model to historical data to estimate how it would have behaved before live implementation.
Backwardation
Backwardation is a futures-curve condition in which contracts for later delivery trade below nearer contracts or the current spot price, under a clearly stated comparison.
Balanced Fund
A balanced fund is a pooled investment vehicle that combines equities and fixed-income securities, often with cash or other assets, under a stated allocation policy.
Bank Loan
A bank loan is debt provided to a company under a negotiated credit agreement, often syndicated among banks and institutional investors. In investment portfolios the term commonly refers to senior secured, floating-rate leveraged loans that can trade in a secondary market.
Barbell Strategy
A barbell strategy concentrates exposure at two ends of a spectrum while holding relatively little in the middle. In bonds, it commonly combines short and long maturities.
Base Currency
Base currency is the first currency in an FX pair and the reference unit whose price is expressed in the quote currency. It can also mean the currency used for portfolio reporting.
Basis Point
A basis point is one hundredth of one percentage point. One basis point equals 0.01%, or 0.0001 in decimal form. Market participants use basis points to state small changes in yields, spreads, fees, and interest rates clearly.
Basis Risk
Basis risk is the possibility that a hedge and the exposure it is intended to offset do not move together as expected. The basis is the price or return difference between related instruments.
Bear Market
A bear market is a sustained, broad decline in the price of a market or asset class, accompanied by weakening confidence and greater investor caution. A fall of 20% from a recent peak is a widely used convention for equity indices, but it is a rule of thumb rather than a universal legal, economic, or statistical definition.
Behavioral Finance
Behavioral finance studies how cognitive shortcuts, emotions, social influences, and institutional settings affect financial judgments and market outcomes.
Benchmark
A benchmark is a transparent reference portfolio, index, rate, or target used to evaluate an investment’s return, risk, and implementation. A suitable benchmark should reflect the mandate’s investable opportunity set and be identifiable, measurable, appropriate, and specified in advance.
Beneficial Ownership
Beneficial ownership describes the person or entity that ultimately enjoys or controls the economic or voting rights of a security, even when legal title is held through a nominee, custodian, trust, or intermediary.
Beneficiary
A beneficiary is a person or organization designated to receive assets, income, rights, or benefits under an account, policy, trust, will, plan, or applicable law.
Best Execution
Best execution is the duty and process of seeking the most favorable reasonably available result for a client order, considering price, cost, speed, likelihood of execution and settlement, size, and other relevant circumstances.
Best-in-Class Investing
Best-in-class investing favors issuers with stronger sustainability characteristics than sector or peer-group competitors rather than excluding entire industries.
Beta
Beta measures how sensitively an investment’s returns have moved relative to a chosen market or benchmark. A beta of 1 indicates benchmark-like sensitivity, above 1 indicates greater sensitivity, and below 1 indicates less, based on the data and model used.
Bid-Ask Spread
The bid-ask spread is the difference between the highest displayed price a buyer offers and the lowest displayed price a seller accepts for a security at a moment in time.
Black-Litterman Model
The Black-Litterman model is an asset-allocation framework that starts with market-implied equilibrium returns and combines them with an investor’s views according to stated confidence. It aims to produce more stable and intuitive expected returns and portfolio weights than unconstrained mean-variance optimization.
Bond
A bond is a debt security representing a loan from an investor to an issuer. Its terms usually specify principal, interest payments, maturity, currency, seniority, and contractual protections. Bondholders are creditors rather than owners and generally rank ahead of shareholders in insolvency.
Book Value
Book value is the accounting value of an asset, liability, or shareholders’ equity recorded on a balance sheet under the applicable reporting standards. For a company, common equity book value generally equals recognized assets minus liabilities and claims senior to common shareholders.
Bottom-Up Investing
Bottom-up investing selects securities primarily through company or asset-level analysis rather than beginning with broad macroeconomic forecasts.
Break-Even Inflation
Break-even inflation is the inflation rate at which a nominal government bond and a comparable inflation-linked bond would deliver the same return if held under the assumed conditions.
Bridge Loan
A bridge loan is short-term financing intended to fund a borrower until a transaction, asset sale, permanent loan, bond issue, or equity raise provides longer-term capital.
Broker-Dealer
A broker-dealer is a person or firm in the business of effecting securities transactions for customers as a broker, trading for its own account as a dealer, or performing both roles.
Bull Market
A bull market is a sustained, broad rise in the price of a market or asset class, usually accompanied by improving confidence and greater willingness to take risk. A gain of 20% from a recent low is sometimes used as a convention, but no single threshold, duration, or economic condition defines every bull market.
Bullet Bond
A bullet bond is a debt security that repays its entire principal at one final maturity date rather than reducing principal through scheduled installments. Coupons may be paid periodically, but principal remains outstanding until maturity.
Business Cycle
The business cycle is the recurring movement of economic activity through expansion, slowdown, contraction, and recovery. Cycles differ in duration, cause, and severity.
Business Development Company
A business development company is a U.S. closed-end investment company that generally invests in small and middle-market businesses and elects to operate under a specific Investment Company Act framework.
Buy-Side
The buy-side consists of organizations that invest capital, including asset managers, pension funds, insurers, hedge funds, and family offices.
Buyout
A buyout is an acquisition of a controlling interest in a company, commonly by a private-equity sponsor using investor capital and debt.
Calendar Spread
A calendar spread is a position combining long and short derivatives on the same or related underlying with different expiration dates. It targets changes in the term structure rather than only outright direction.
Call Option
A call option gives its holder the right, but not the obligation, to buy an underlying asset at a strike price by or at expiration. The writer has the corresponding obligation if exercised.
Callable Bond
A callable bond gives the issuer the right to redeem the debt before its scheduled maturity at specified dates and prices. The investor has effectively sold the issuer an option, usually receiving extra yield in exchange for uncertain maturity and capped price appreciation.
Capacity
Investment capacity is the amount of capital a strategy can manage before market impact, opportunity scarcity, liquidity, or organizational limits materially reduce expected returns.
Capital Call
A capital call is a formal request by a private fund for investors to contribute part of their committed but unfunded capital by a specified date.
Capital Gain
A capital gain is the increase recognized when a capital asset is disposed of for proceeds above its adjusted basis. Tax definitions, exemptions, rates, and recognition events vary by jurisdiction.
Capital Gains Tax
Capital gains tax is tax imposed by a jurisdiction on qualifying gains from disposing of capital assets.
Capital Introduction
Capital introduction is a service, commonly offered by a prime broker, that facilitates connections between investment managers and prospective institutional or qualified investors.
Capital Preservation
Capital preservation is an investment objective focused on limiting permanent loss and maintaining purchasing or nominal value over a stated horizon. It prioritizes resilience, liquidity, and downside control, but cannot guarantee that a portfolio will avoid all market declines.
Capital Structure
Capital structure is the mix and priority of financing claims used by a company, including common equity, preferred equity, secured and unsecured debt, leases, and hybrid securities. It determines how operating value, cash flows, control, and losses are distributed among capital providers.
Carried Interest
Carried interest is a share of investment profits allocated to a private-fund manager or general partner under the fund agreement, usually after specified return and capital conditions are met.
Carry Trade
A currency carry trade borrows or sells a lower-yielding currency to invest in a higher-yielding currency or asset, seeking to earn the rate differential.
Cash Equivalents
Cash equivalents are highly liquid, short-maturity investments readily convertible into known amounts of cash and carrying insignificant risk of value change. Accounting definitions commonly require an original maturity of three months or less, subject to the applicable standard.
Cash Flow Yield
Cash flow yield compares a measure of cash generation with an investment’s market value or price. For equities, free cash flow yield commonly divides free cash flow available to shareholders by equity value, or unlevered free cash flow by enterprise value.
Cash Sweep
A cash sweep is a contractual or operational mechanism that directs available cash toward a predetermined use, commonly mandatory debt repayment. The definition of excess cash, permitted deductions, payment percentage, and timing is set by the governing agreement.
Charitable Giving
Charitable giving transfers money, securities, property, time, or other value to eligible charitable organizations or purposes.
Clawback
A clawback is a contractual mechanism requiring a manager or other recipient to return previously distributed compensation when later results show that it received more than the final agreed amount.
Climate Risk
Climate risk is financial risk from physical climate effects and from economic transition toward lower greenhouse-gas emissions.
Closed-End Fund
A closed-end fund is a pooled investment company with a generally fixed number of shares that trade between investors in a secondary market. Unlike a conventional open-end mutual fund, it normally does not redeem shares daily at net asset value.
Closet Indexing
Closet indexing is managing a portfolio that is presented or priced as active while its holdings and returns remain very close to a benchmark.
Co-Investment
A co-investment is a direct investment alongside a lead private fund or sponsor in a specific company or asset, usually outside the main pooled vehicle.
Collateral
Collateral is an asset or pool of assets pledged to secure an obligation and available to a creditor under agreed conditions if the borrower fails to perform.
Collateralized Loan Obligation
A collateralized loan obligation is a securitization that owns a diversified pool of mainly leveraged corporate loans and issues tranches with different priorities for income and principal.
Commercial Paper
Commercial paper is a short-term unsecured debt instrument issued by companies and certain financial entities to fund working capital and other near-term needs. It is usually sold at a discount or with interest and matures within one year.
Committed Capital
Committed capital is the amount an investor contractually agrees to provide to a private fund over its investment period, whether or not it has yet been called.
Commodity
A commodity is a relatively standardized physical good, such as crude oil, natural gas, copper, wheat, or gold, traded for commercial use or investment. Exposure may come through physical ownership, futures, swaps, producer shares, or pooled vehicles.
Common Stock
Common stock is an equity security representing a residual ownership interest in a company. Holders generally participate in profits and asset value after creditors and preferred shareholders, and may receive voting rights and dividends subject to the company’s charter and board decisions.
Compound Annual Growth Rate
Compound annual growth rate, or CAGR, is the constant annual rate that would turn a beginning value into an ending value over a specified number of years. It summarizes compounded growth even when the actual year-by-year path was uneven.
Compounding
Compounding is the process by which investment gains or financing costs generate further gains or costs over subsequent periods.
Concentration Risk
Concentration risk is the possibility that excessive exposure to one issuer, industry, country, factor, counterparty, or economic theme causes a disproportionate portfolio loss. It can arise through one large holding or through many holdings that share the same underlying driver.
Conditional Value at Risk
Conditional Value at Risk estimates the average loss in outcomes that are worse than the Value at Risk threshold at a chosen confidence level. It focuses on the tail of the loss distribution and is commonly treated as equivalent to expected shortfall under standard conditions.
Confirmation Bias
Confirmation bias is the tendency to seek, interpret, remember, or overweight information that supports an existing belief while discounting contrary evidence.
Consumer Price Index
The Consumer Price Index, or CPI, measures changes over time in prices paid by consumers for a defined basket of goods and services. Methodology, population, and coverage differ by country.
Contango
Contango is a futures-curve condition in which contracts for later delivery trade above nearer contracts or the current spot price, under a clearly stated comparison.
Convertible Arbitrage
Convertible arbitrage typically buys a convertible security and shorts related equity to trade bond, option, credit, and volatility value.
Convertible Bond
A convertible bond is corporate debt that allows the holder to exchange it for a specified number of the issuer’s shares under contractual terms. Its value combines a bond floor with an equity conversion option, producing both credit and equity sensitivity.
Convexity
Convexity measures how a bond’s price sensitivity changes as yield changes. It captures curvature in the price-yield relationship and improves on duration, which provides only a linear first-order estimate.
Core-Satellite Portfolio
A core-satellite portfolio combines a broad, usually low-cost core holding with smaller satellite allocations designed to add return, manage a specific risk, or provide differentiated exposure. The core supplies market coverage while satellites express active or specialized views.
Corporate Bond
A corporate bond is debt issued by a company to finance operations, investment, acquisitions, or refinancing. The issuer promises contractual interest and principal payments, while investors accept credit, interest-rate, liquidity, and structural risks in exchange for expected income and return.
Corporate Governance
Corporate governance is the system of authority, oversight, incentives, rights, and accountability through which a company is directed and controlled.
Correlation
Correlation is a standardized measure of how two return series move together, ranging from -1 to +1. A value near +1 indicates similar movement, zero indicates little linear relationship, and -1 indicates opposite movement over the measured sample.
Cost Basis
Cost basis is the value assigned to an investment for determining gain, loss, and sometimes tax, adjusted for applicable fees, distributions, splits, transfers, and other events.
Counterparty Risk
Counterparty risk is the possibility that the other party to a financial contract fails to make a payment, deliver an asset, return collateral, or otherwise perform as agreed. The exposure can change with market prices before the contract matures or is replaced.
Coupon
A coupon is the contractual interest payment on a bond. The coupon rate is normally stated as an annual percentage of face value, while payments may occur annually, semiannually, quarterly, monthly, or under a floating formula specified in the bond documents.
Covenant
A covenant is a contractual promise in a debt agreement that requires or restricts specified borrower actions, disclosures, financial conditions, or use of collateral.
Credit Default Swap
A credit default swap, or CDS, is a contract in which a protection buyer pays periodic premiums and the seller compensates defined loss if a reference borrower or obligation experiences a covered credit event.
Credit Rating
A credit rating is an opinion from a rating agency about the relative creditworthiness of an issuer or specific obligation under the agency’s methodology and rating scale.
Credit Risk
Credit risk is the possibility of financial loss because a borrower, bond issuer, or contractual counterparty cannot or will not meet its obligations. It includes default risk, deterioration in credit quality, loss severity, and changes in the market price of credit exposure.
Credit Spread
A credit spread is the additional yield on a debt instrument relative to a reference rate or benchmark with similar maturity. It compensates investors for expected credit loss, uncertainty, liquidity, optionality, and other risks not present in the chosen reference.
Cross-Default
A cross-default clause makes a default on one specified obligation a default under another agreement, usually after thresholds and grace periods are met.
Crowded Trade
A crowded trade is a position or strategy held by many investors in similar form, creating correlated entry, financing, hedging, or exit behavior.
CTA
A commodity trading advisor, or CTA, is a regulated person or firm that advises on futures, options on futures, retail foreign exchange, or swaps under applicable U.S. rules. The term also commonly describes managed-futures programs.
Cumulative Return
Cumulative return is the total percentage change in an investment’s value over a specified period, including reinvested income when the return series is defined on a total-return basis.
Currency Appreciation
Currency appreciation is an increase in one currency’s value relative to another, allowing it to purchase more of the other currency.
Currency Depreciation
Currency depreciation is a market-driven decline in one currency’s value relative to another under a floating or managed regime.
Currency Devaluation
Currency devaluation is an official reduction in a currency’s target value under a fixed or managed exchange-rate regime.
Currency Forward
A currency forward is an agreement to exchange specified amounts of two currencies at a fixed rate on a future date. It is usually negotiated over the counter and settled physically or in cash.
Currency Hedging
Currency hedging uses forwards, futures, options, swaps, or matching cash flows to reduce the effect of exchange-rate movements on foreign assets, liabilities, income, or spending.
Currency Pair
A currency pair expresses one currency’s value in units of another, conventionally written as base currency followed by quote currency.
Currency Risk
Currency risk is the possibility that exchange-rate changes alter the base-currency value of foreign assets, liabilities, cash flows, or operating results.
Custodian
A custodian safeguards financial assets and records, supports settlement, collects income, processes corporate actions, and provides asset-servicing information.
Debt-to-Equity Ratio
The debt-to-equity ratio compares a company’s debt with shareholders’ equity. It is a leverage indicator showing how much creditor financing supports the business relative to the accounting capital attributed to owners.
Default
Default is a borrower or contractual party’s failure to meet an obligation under agreed terms. It can involve missed payment, covenant breach, bankruptcy, restructuring, or another specified credit event.
Default Rate
Default rate measures the proportion of borrowers, issuers, or debt amount that enters default during a specified period. It can be calculated by issuer count or debt value, and the definition of default and population must be stated.
Defensive Equity
Defensive equity refers to shares or equity strategies expected to be less sensitive to economic weakness or broad market declines. They often emphasize stable demand, resilient cash flow, strong balance sheets, lower beta, dividends, or sectors such as consumer staples and utilities.
Deferred Tax Asset
A deferred tax asset is an accounting balance representing future tax benefits expected from deductible temporary differences, tax-loss carryforwards, or tax credits. Recognition depends on whether the company is considered likely to generate sufficient taxable income to use those benefits.
Delta
Delta estimates how much a derivative’s value changes for a small change in the underlying price, holding other inputs constant. Option delta also approximates directional exposure and changes over time.
Delta Hedging
Delta hedging offsets a derivative portfolio’s estimated directional sensitivity by trading the underlying asset or other instruments. The hedge is rebalanced as delta changes.
Derivative
A derivative is a contract whose value depends on an underlying asset, rate, index, event, or other reference. Futures, forwards, options, and swaps can transfer risk, create exposure, or alter cash-flow timing without purchasing the reference directly.
Direct Lending
Direct lending is privately negotiated credit provided by non-bank lenders directly to companies, often to middle-market borrowers.
Discount Rate
A discount rate is the required rate used to convert future cash flows into present value. It reflects the time value of money and compensation for the uncertainty, risk, currency, and opportunity cost associated with the cash flows being valued.
Discretionary Investing
Discretionary investing relies materially on human judgment to select, size, time, and exit positions rather than following a fully specified mechanical rule.
Disposition Effect
The disposition effect is the tendency to sell investments showing gains too readily while retaining losing positions too long.
Distressed Debt
Distressed debt is the debt of an issuer experiencing severe financial or operational difficulty, often trading at a large discount because default, restructuring, or bankruptcy is considered likely.
Distribution
A distribution is cash, securities, or other value paid by a company, fund, trust, or partnership to investors under its governing and legal framework.
Distribution Yield
Distribution yield annualizes recent or expected distributions and divides them by current price or NAV under a stated convention.
Diversification
Diversification is the practice of combining investments with different return drivers so that a setback in one does not determine the result of the entire portfolio. Effective diversification depends on exposures and correlations, not simply on owning many securities or funds.
Dividend
A dividend is a distribution of company value to shareholders, commonly paid in cash or shares when declared under applicable corporate rules.
Dividend Yield
Dividend yield is annual dividends per share divided by current share price, expressed as a percentage.
Dollar Duration
Dollar duration estimates the change in a bond or portfolio’s monetary value for a change in yield. It converts percentage sensitivity into currency exposure, making interest-rate risk comparable across positions with different market values.
Dollar-Cost Averaging
Dollar-cost averaging is investing a fixed currency amount at regular intervals regardless of market price, so more units are bought when prices are lower and fewer when prices are higher.
Downside Capture
Downside capture measures how a portfolio performed relative to a benchmark during periods when that benchmark declined. A ratio below 100% generally means the portfolio lost less than the benchmark in those periods, while a negative ratio can indicate it gained.
Drawdown
A drawdown is the decline in an investment or portfolio from a previous peak to a later value before a new peak is reached. It is normally expressed as a percentage and tracks the investor’s experienced loss from the high-water mark.
Drawn Capital
Drawn capital is the portion of an investor’s commitment that a private fund has called and the investor has contributed.
Due Diligence
Due diligence is the structured investigation of an investment, manager, counterparty, or transaction before commitment and throughout ownership.
Duration
Duration is a family of measures describing the timing of a bond’s cash flows or its price sensitivity to changes in yield. Macaulay duration is a weighted average time, while modified and effective duration estimate percentage price response.
Duration Matching
Duration matching is aligning the interest-rate sensitivity of assets with that of a liability or target cash-flow obligation to reduce changes in the funding position when yields move.
Earnings Before Interest Taxes Depreciation and Amortization
EBITDA is earnings before interest, taxes, depreciation, and amortization. It is a non-GAAP operating measure used to compare businesses before financing, tax jurisdiction, and selected non-cash charges, but it is not cash flow.
Earnings Per Share
Earnings per share, or EPS, allocates a company’s profit available to common shareholders across its weighted-average common shares. Basic EPS uses shares outstanding, while diluted EPS includes potentially dilutive instruments when required by accounting rules.
Economic Moat
An economic moat is a durable competitive advantage that allows a company to defend customers, margins, returns on capital, or market position against competitors.
Effective Duration
Effective duration estimates a security’s percentage price sensitivity to a change in benchmark yields while allowing expected cash flows to change. It is especially useful for bonds with calls, prepayments, or other embedded options.
Efficient Frontier
The efficient frontier is the set of portfolios offering the highest expected return for each level of expected risk, or the lowest expected risk for each return. Portfolios below the frontier are inefficient because another feasible mix has a better expected risk-and-return trade-off.
Emerging Markets
Emerging markets are economies and securities markets that are developing in income, institutions, liquidity, or market accessibility relative to established developed markets. Index-provider classifications differ and can change over time.
Endowment
An endowment is a pool of donated or designated assets invested to support an institution over a long horizon while balancing current spending and future purchasing power.
Endowment Effect
The endowment effect is valuing an asset more highly merely because one owns it than one would if deciding whether to acquire it today.
Enterprise Value
Enterprise value estimates the market value of a company’s operating business available to all capital providers. A common calculation adds equity market capitalization and debt, then subtracts cash and adjusts for preferred stock, non-controlling interests, and other financing claims.
Environmental Social and Governance
Environmental, social, and governance, or ESG, describes categories of information about an issuer’s environmental impacts, people and stakeholder relationships, and governance structures.
Equity
Equity is the residual ownership claim on an entity after liabilities and senior claims are deducted from its assets. In public markets it is commonly represented by shares, while accounting equity records the balance-sheet interest attributable to owners under applicable reporting standards.
Equity Long Bias
Equity long bias is a strategy maintaining net positive exposure to equities over time while retaining flexibility to hold short positions or hedges. Returns are expected to benefit from rising equity markets, but active selection and risk management can alter participation.
Equity Risk Premium
The equity risk premium is the additional return investors require or expect from equities over a risk-free asset. It compensates for uncertainty in corporate cash flows and market prices and is a central input to cost-of-equity and valuation models.
ESG Integration
ESG integration is the systematic inclusion of financially material environmental, social, and governance information in investment analysis and decisions.
Estate Planning
Estate planning coordinates ownership, control, support, and transfer of assets during incapacity and after death under applicable law.
Event Driven
Event driven is a strategy investing around corporate events such as mergers, restructurings, spin-offs, bankruptcies, recapitalizations, and activist campaigns.
Exchange Rate
An exchange rate is the price of one currency expressed in units of another. A quote must identify both currencies, direction, value date, and market convention.
Exchange-Traded Fund
An exchange-traded fund, or ETF, is a pooled investment vehicle whose shares trade on an exchange throughout the day. Many ETFs use authorized participants to create or redeem large blocks of shares, helping market price remain near portfolio value.
Exclusionary Screening
Exclusionary screening removes issuers, sectors, countries, or activities from an investment universe under defined values, risk, legal, or sustainability criteria.
Execution Shortfall
Execution shortfall is the difference between a portfolio’s value using a decision-price benchmark and its value after actual execution, including explicit costs and the opportunity cost of unfilled trades.
Expected Return
Expected return is a probability-weighted estimate of an investment’s future return over a specified horizon. It can come from scenarios, valuation models, market-implied information, historical evidence, or capital-market assumptions and is an estimate rather than a promised outcome.
Expected Shortfall
Expected shortfall estimates the average loss in outcomes beyond a chosen confidence threshold over a stated horizon. It asks how severe losses are after the portfolio enters the tail.
Expense Ratio
An expense ratio is a fund’s recurring operating expenses expressed as a percentage of its average net assets. It commonly includes management, administration, custody, accounting, and other fund costs, but the exact inclusions depend on the jurisdiction and disclosure document.
Face Value
Face value is the stated principal amount of a debt security used to determine contractual payments and the amount normally due at maturity. It is not necessarily the security’s current market price.
Factor Exposure
Factor exposure measures how sensitive a security or portfolio is to systematic drivers such as equity beta, value, momentum, size, quality, rates, credit, or currency.
Factor Investing
Factor investing systematically targets characteristics associated with differences in expected return or risk, such as value, momentum, quality, size, carry, or low volatility.
Fair Value
Fair value is an estimate of the price at which an asset or liability could be exchanged in an orderly transaction between market participants at the measurement date. In investment analysis, the phrase can also describe an analyst’s estimate of intrinsic worth.
Family Office
A family office is an organization managing investments and often tax, estate, reporting, philanthropy, and administrative affairs for one or more wealthy families.
Federal Funds Rate
The federal funds rate is the overnight rate on unsecured reserve lending between eligible U.S. banks. The Federal Reserve sets a target range and implements policy to keep the effective market rate near it.
Fee Offset
A fee offset reduces one category of management compensation by fees or other income the manager receives from portfolio companies, transactions, monitoring, consulting, or related activities.
Fiduciary
A fiduciary is a person or organization required under applicable law or mandate to act with specified loyalty, care, prudence, or other duties for another party.
Financial Plan
A financial plan is a documented framework connecting goals with cash flow, assets, liabilities, investments, tax, insurance, and implementation actions.
Fixed Income
Fixed income is an asset class of debt instruments that promise or target contractual cash flows, such as interest and principal, subject to issuer, structure, and legal terms. It includes government bonds, corporate debt, securitized products, loans, and money-market instruments.
Floating Rate Note
A floating rate note is a debt security whose coupon resets periodically using a reference rate plus or minus a contractual spread. The reference may be an overnight benchmark, treasury bill rate, or another specified index.
Foreign Exchange
Foreign exchange, or FX, is the market and process through which currencies are bought, sold, borrowed, lent, and exchanged for international trade, investment, funding, and risk management.
Form 4
Form 4 is a U.S. SEC filing used by specified company insiders to report many changes in beneficial ownership of an issuer’s securities.
Forward Exchange Rate
A forward exchange rate is the rate agreed today for exchanging two currencies on a specified future date. It combines the spot rate with the currencies’ interest-rate differential over the term.
Framing Effect
The framing effect occurs when equivalent information produces different decisions because it is presented as a gain, loss, percentage, probability, or comparison.
Free Cash Flow
Free cash flow is cash generated after the operating and investment spending required to sustain or grow a business. Free cash flow to the firm is available to debt and equity providers, while free cash flow to equity is after financing effects.
Frontier Markets
Frontier markets are smaller, less liquid, or less accessible capital markets than those generally classified as emerging markets. They may have early-stage exchanges, limited foreign ownership, narrow sector representation, and developing market infrastructure.
Fund of Funds
A fund of funds is a pooled vehicle that invests mainly in other funds rather than directly in individual securities or assets. The manager selects, sizes, monitors, and replaces underlying managers to pursue a combined portfolio objective.
Fundamental Analysis
Fundamental analysis estimates investment value and risk from business economics, financial statements, industry structure, management, capital allocation, and security terms.
Fundamental Equity
Fundamental equity is an investment approach that selects and values shares through analysis of a company’s business model, financial statements, competitive position, management, industry, and expected cash flows rather than relying solely on market-price patterns.
Fundamental Law of Active Management
The fundamental law of active management is a framework relating risk-adjusted active performance to forecasting skill and the number of independent opportunities, subject to implementation.
Futures Contract
A futures contract is a standardized exchange-traded agreement to buy or sell a reference asset or settle its value at a future date. A clearinghouse intermediates performance and positions are margined.
Gamma

Key Person Clause
A key person clause sets consequences when specified individuals stop devoting the required time to a fund, become unavailable, leave the manager, or otherwise trigger defined conditions.
Kurtosis
Kurtosis is a statistical measure related to the weight of a distribution’s tails relative to its overall dispersion. Excess kurtosis often identifies returns with more extreme observations than a normal distribution.
Large Cap
Large cap refers to companies with relatively high equity market capitalization within a specified market or index. There is no universal monetary cutoff, so classification depends on provider rules, geography, date, and the investable universe.
Leverage
Leverage is the use of debt, derivatives, or other contractual exposure to increase the economic sensitivity of an investment beyond the capital funded by equity. It can amplify gains, losses, income, volatility, liquidity needs, and the risk of forced action.
Leveraged Buyout
A leveraged buyout, or LBO, acquires control of a company using substantial debt secured by or serviced from the target’s cash flows and assets.
Liability-Driven Investing
Liability-driven investing is a portfolio approach that begins with the timing, amount, currency, inflation sensitivity, and uncertainty of obligations rather than selecting assets from a return target alone.
Limit Order

Long Position
A long position is ownership or economic exposure that generally gains value when the price of an asset rises and loses value when it falls.
Long/Short Equity
Long/short equity is a strategy that combines positions expected to rise with short positions expected to fall or underperform. The manager seeks returns from security selection while choosing how much net market direction and total gross exposure the portfolio should carry.
Loss Aversion
Loss aversion is the tendency for losses relative to a reference point to feel more significant than equivalent gains.

A master-feeder fund is a structure in which one or more feeder vehicles collect capital from different investor groups and invest substantially all of it into a common master portfolio.
Maturity
Maturity is the contractual date on which a debt instrument’s remaining principal is due, assuming it has not been called, prepaid, converted, extended, or defaulted. It also describes the time remaining until that date.
Maximum Drawdown
Maximum drawdown is the largest peak-to-trough percentage decline observed for an investment over a specified period. It records the worst historical loss from a prior high before recovery, combining the size and path of losses into an intuitive downside measure.
Mean Reversion
Mean reversion is the tendency of a price, spread, valuation, or other variable to move back toward a historical or economically estimated central level after deviating from it.
Mental Accounting
Mental accounting is treating money differently according to arbitrary categories, sources, accounts, or intended uses rather than its role in total wealth.
Merger Arbitrage
Merger arbitrage invests in announced acquisitions, usually buying the target below offer value and sometimes hedging with acquirer shares.
Mid Cap
Mid cap describes companies in the middle range of equity market capitalization within a defined market universe. Boundaries vary by index provider and move as prices, share counts, free float, and classifications change.
Minimum Variance Portfolio
A minimum variance portfolio is the feasible combination of investments with the lowest estimated return variance under stated constraints. The global minimum variance portfolio is the leftmost point of the efficient frontier and does not require a target expected return.
Modified Duration
Modified duration estimates the percentage change in an option-free bond’s price for a small change in yield to maturity. It adjusts Macaulay duration for the bond’s yield and compounding frequency.

Net present value, or NPV, is the present value of expected future cash inflows minus the present value of cash outflows. A positive NPV indicates that a project or investment is expected to create value above the return required by the selected discount rate.
Net Zero
Net zero is a state in which greenhouse-gas emissions within a defined boundary are balanced by removals over a stated period after deep reductions.
Netting
Netting combines offsetting payment, exposure, or settlement obligations so that only a net amount is transferred or treated as at risk under an enforceable agreement.
Nominal Return
Nominal return is an investment’s gain or loss measured in money terms without removing inflation’s effect on purchasing power.
Non-Performing Loan
A non-performing loan is a loan for which contractual payments are materially overdue or full collection is judged unlikely, under the applicable accounting, regulatory, or portfolio definition.
Notional Value
Notional value is the reference amount used to calculate derivative payments or economic exposure. It is often much larger than cash invested, collateral posted, or current market value.

An option is a contract granting its buyer a right, but not an obligation, to transact in an underlying reference at specified terms. The seller receives premium and accepts a contingent obligation.
Option-Adjusted Spread
Option-adjusted spread is the constant spread added to a benchmark yield curve in a valuation model so the present value of expected option-dependent cash flows equals a security’s market price.
Overconfidence Bias
Overconfidence bias is the tendency to overestimate the accuracy of one’s knowledge, forecasts, control, or investment skill.
Overlay Strategy
An overlay strategy is a separately managed layer of positions, often derivatives, applied over an underlying portfolio to alter risk, exposure, liquidity, or implementation.

A realized gain is an increase in value recognized when an asset is sold, exchanged, redeemed, settled, or otherwise treated as disposed of.
Rebalancing
Rebalancing is the process of returning a portfolio toward its target allocation after market movements, cash flows, or other changes cause weights to drift. It maintains the risk profile chosen in the investment policy rather than seeking to forecast the next market move.
Recency Bias
Recency bias gives disproportionate weight to recent events when estimating probabilities, trends, or future returns.
Recession
A recession is a broad and material decline in economic activity lasting more than a brief interruption. Formal definitions and dating methods differ by country and institution.

Risk Budget
A risk budget is a framework that allocates a portfolio’s allowed risk among asset classes, strategies, managers, or positions. Unlike a capital budget, it focuses on each component’s contribution to uncertainty or loss, which depends on volatility, correlation, and portfolio weight.
Risk Parity
Risk parity is a portfolio approach that balances contributions to risk across assets or asset groups rather than assigning equal amounts of capital. Lower-volatility assets generally receive larger capital weights, and leverage may be used to reach a desired total return or risk level.
Risk Premium
A risk premium is the additional expected return investors require for bearing a specified risk relative to a lower-risk reference investment.
Risk Tolerance
Risk tolerance is an investor’s willingness to accept uncertainty and loss, considered alongside financial capacity and required risk.
Risk-Adjusted Return

Short Selling
Short selling is the practice of selling a borrowed security with the intention of buying it back later and returning it to the lender. The seller generally profits if the purchase price is lower than the original sale price and loses if the security rises.
Side Letter
A side letter is an agreement that grants a particular investor terms, rights, disclosures, or protections that supplement or modify the main fund documents.
Side Pocket
A side pocket is a fund mechanism that segregates illiquid, hard-to-value, or restricted assets from the main portfolio and allocates their economics to designated investors.
Skewness
Skewness measures asymmetry in a distribution. Negative return skewness indicates a longer or heavier left tail, while positive skewness indicates a longer or heavier right tail.
Slippage
Slippage is the difference between an expected, decision, or quoted trade price and the price actually achieved. It can arise from spread, delay, market movement, order size, and execution method.

Standard deviation measures how dispersed a set of returns is around its arithmetic mean. In investing, it is commonly used as historical volatility: a larger standard deviation indicates returns varied more widely during the measured sample, without distinguishing gains from losses.
Status Quo Bias
Status quo bias is preferring an existing choice or allocation because it is current, even when alternatives may better meet objectives.
Stewardship
Stewardship is the responsible use of investor rights and influence to protect and enhance long-term value for clients and beneficiaries.

Tactical Asset Allocation
Tactical asset allocation is a deliberate, temporary departure from long-term policy weights to express a view on relative market opportunities or risks. The portfolio is expected to return toward its strategic allocation when the view expires, reaches its objective, or proves incorrect.
Tail Risk
Tail risk is the possibility of unusually large gains or losses in the extreme ends of a return distribution, with investment risk discussions usually focused on severe losses. These outcomes occur infrequently but can dominate long-term results, liquidity needs, and portfolio survival.
Tax Lot
A tax lot is a separately identifiable group of investment units acquired at a particular date, price, and adjusted cost basis.
Tax-Deferred Account
A tax-deferred account postpones some tax on investment income or gains until withdrawal or another defined event under applicable law.
Tax-Loss Harvesting
Tax-loss harvesting realizes investment losses to offset gains or other taxable amounts where applicable while maintaining an intended portfolio exposure.
Tender Offer
A tender offer is a public or private invitation to security holders to sell some or all of their holdings at stated terms during a specified period.
Term Premium
The term premium is the additional expected return investors may require for holding a longer-term bond instead of repeatedly investing in shorter-term instruments over the same horizon.
Thematic Investing
Thematic investing builds exposure around a long-term trend such as clean energy, water, health, automation, or demographic change.
Theta
Theta measures the change in an option’s modeled value as time passes, holding other pricing inputs constant. It is often quoted as the approximate change over one day.
Top-Down Investing
Top-down investing begins with broad economic, policy, market, country, sector, or asset-class analysis before selecting securities or instruments to express the resulting views.
Total Expense Ratio
Total expense ratio is a fund’s recurring operating expenses expressed as a percentage of its average net assets under the applicable reporting convention.
Total Return
Total return is the complete gain or loss from an investment over a period, combining price change with income and distributions, with reinvestment handled according to the stated methodology. It is normally expressed as a percentage of beginning value.
Tracking Error
Tracking error is the standard deviation of a portfolio’s returns relative to its benchmark. It measures how variable active return has been, indicating the scale of benchmark-relative risk rather than whether the portfolio outperformed.
Trade-Weighted Dollar
The trade-weighted dollar is an index measuring the U.S. dollar’s value against a basket of foreign currencies, with weights reflecting U.S. trade relationships under the index methodology.
Trailing Return
Trailing return is the investment return over a period ending on a stated recent date, such as trailing one year, three years, or five years.
Tranche
A tranche is a class of securities within a financing or securitization that has distinct priority, risk, maturity, coupon, or exposure to cash flows and losses.
Transaction Cost
Transaction cost is the total economic cost of buying, selling, financing, or transferring an investment, including explicit charges and implicit execution effects.
Transition Risk
Transition risk is financial risk arising from policy, technology, market, legal, and behavioral changes during the shift toward a lower-carbon economy.
Treasury Inflation-Protected Security
A Treasury Inflation-Protected Security is a U.S. Treasury marketable security whose principal is adjusted using the Consumer Price Index, with a fixed coupon rate applied to adjusted principal.
Treasury Yield Curve
The Treasury yield curve plots yields on U.S. Treasury securities across maturities at a given time under a specified yield convention.
Trend Following
Trend following is a systematic approach that takes long or short positions based on the direction and persistence of past price movements rather than a forecast of fundamental value.
Trust
A trust is a legal arrangement in which a trustee holds or administers property for beneficiaries or stated purposes under governing terms.
Turnover
Portfolio turnover measures how much of a portfolio is bought and sold over a period relative to its average assets or holdings. Calculation conventions vary across funds and jurisdictions.
UCITS
UCITS is the European Union framework for collective investment funds that meet harmonized rules on authorization, eligible assets, diversification, liquidity, custody, disclosure, and investor protection.
Unconstrained Strategy
An unconstrained strategy has broad flexibility to allocate exposures without closely tracking a conventional benchmark, subject to mandate and risk limits.
Underweight
Underweight means holding a smaller portfolio weight in a security, sector, country, asset class, or factor than its weight in a stated benchmark or neutral allocation.
Undrawn Capital
Undrawn capital is the portion of an investor’s legally committed capital to a private fund that has not yet been called and funded by the manager.
Unit Trust
A unit trust is a pooled investment vehicle constituted under a trust arrangement in which investors hold units representing a beneficial interest in the fund’s assets.
Unrealized Gain
An unrealized gain is the increase in an investment’s current value above its relevant basis while the position remains held.
Upside Capture
Upside capture measures how a portfolio performed relative to a benchmark during periods when the benchmark had positive returns, usually expressed as a percentage.
Value at Risk
Value at Risk, or VaR, estimates a loss threshold that should not be exceeded over a stated horizon at a stated confidence level under a specified model. It summarizes ordinary downside exposure in one number but does not describe how severe losses may be beyond the threshold.
Value Investing
Value investing seeks securities trading below a reasoned estimate of intrinsic worth or at prices offering unusually attractive compensation for their fundamentals. The approach emphasizes valuation discipline, downside protection, and a margin of safety rather than simply buying statistically cheap assets.
Vega
Vega measures the change in an option’s modeled value for a one-percentage-point change in implied volatility, holding other pricing inputs constant.
Venture Capital
Venture capital is equity financing for young, high-growth companies with uncertain business models, limited operating history, and potential for large outcomes.
Vintage Year
Vintage year identifies the year in which a private-market fund began investing or held its initial closing, according to the convention used by the data provider.
Volatility
Volatility describes how widely investment returns vary over time and is usually measured by the annualized standard deviation of periodic returns. Higher volatility means returns have been more dispersed around their average, but it does not specify their direction or the cause of changes.
Volatility Arbitrage
Volatility arbitrage seeks to profit from differences between volatility priced in derivatives and the volatility, correlation, or distribution a manager expects to realize.
Volume
Trading volume is the number of shares, contracts, units, or notional amount transacted during a stated period. It measures activity, not the direction or quality of investor conviction.
Warrant
A warrant is a security giving its holder the right, but not the obligation, to buy or sometimes sell an issuer’s security at specified terms before or at expiry.
Wealth Planning
Wealth planning coordinates investments, spending, liabilities, tax, estate, insurance, philanthropy, and family objectives in one framework.
Weighted Average Cost of Capital
Weighted average cost of capital, or WACC, estimates the blended required return demanded by a company’s debt and equity providers, weighted by their market values. It is commonly used to discount unlevered free cash flow to the firm.
Will
A will is a legal document directing certain property transfers and appointments after death, subject to applicable succession and probate law.
Withholding Tax
Withholding tax is deducted by a payer or intermediary from income or proceeds before the recipient receives the payment.
Yield
Yield expresses an investment’s income or implied return relative to its price, face value, or another capital base under a stated convention. For bonds, common measures include current yield, yield to maturity, yield to call, and various spread-based yields.
Yield Curve
A yield curve plots yields against maturity for instruments with comparable credit and structural characteristics.
Yield to Maturity
Yield to maturity, or YTM, is the single discount rate that equates a bond’s current price with the present value of its promised coupons and principal through maturity. It is an internal rate of return based on contractual cash flows and stated compounding conventions.
Zero-Coupon Bond
A zero-coupon bond pays no periodic coupon. It is normally issued or purchased below its redemption value, and the investor’s return comes from the difference between purchase price and principal received at maturity.
