Assets under management (AUM)

The total market value of all investments a firm manages on behalf of clients. It measures the size and reach of an asset manager and drives fee revenue, since most management fees are charged as a percentage of this value.

Related: Management fee, Institutional investor
Institutional investor

An organization such as a pension fund, insurance company, endowment, or sovereign wealth fund that invests large sums, often on behalf of others. It typically trades in bigger sizes and negotiates lower fees than an individual retail investor.

Related: Retail investor, Assets under management (AUM)
Retail investor

An individual who invests personal savings rather than money pooled from an organization. Retail investors usually invest smaller amounts, pay published fees, and are often protected by specific disclosure and suitability rules.

Related: Institutional investor, Suitability

An incentive charge paid to a manager when returns exceed a stated benchmark or hurdle. It rewards outperformance but can encourage risk-taking, so it is often paired with a high-water mark.

Related: High-water mark, Management fee
Fiduciary duty

A legal obligation to act in the client's best interest, placing the client's interests ahead of the firm's own. It typically requires loyalty, care, and full disclosure of conflicts.

Primary market

The market where securities are first sold by an issuer to investors, raising new capital for the company or government. Proceeds go to the issuer rather than to a previous owner.

Related: Secondary market, Initial public offering (IPO)

The market where investors trade securities they already own, such as on a stock exchange. The issuer receives no proceeds, but liquidity and price discovery benefit all holders.

Related: Primary market, Liquidity
Initial public offering (IPO)

The first sale of a company's shares to the public, moving it from private to listed ownership. It raises capital for the firm and creates a tradable market for existing shareholders.

Related: Primary market, Secondary market
Bid-ask spread

The gap between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask). A narrower spread signals a more liquid, lower-cost market for traders.

A firm that continuously quotes buy and sell prices for a security, earning the spread while supplying liquidity. Market makers help ensure that other participants can trade quickly at fair prices.

Related: Bid-ask spread, Liquidity
Liquidity

The ease and speed with which an asset can be bought or sold without materially moving its price. Cash is the most liquid asset; property and private equity are far less liquid.

Related: Bid-ask spread, Market maker
Volatility

A statistical measure of how much an asset's price fluctuates over time. Higher volatility means wider swings and greater uncertainty, which investors usually demand extra return to accept.

Related: Risk, Standard deviation
Price discovery

The process by which buyers and sellers interact to establish a market price reflecting available information. Active trading and competition among participants make this process more efficient.

Related: Efficient market hypothesis, Secondary market
Efficient market hypothesis

The theory that asset prices quickly reflect all available information, making consistent excess returns difficult. Its weak, semi-strong, and strong forms differ in what information is assumed to be priced in.

Related: Price discovery, Index fund
Equity

Ownership interest in a company, represented by shares that carry claims on residual profits and assets. Equity offers growth potential but ranks behind debt in a liquidation.

Related: Dividend, Common stock
Common stock

The most widely held class of equity, typically granting voting rights and a residual claim on earnings and assets. Holders are last in line to be paid if the company fails.

Related: Equity, Dividend
Dividend

A distribution of company profits to shareholders, usually paid in cash on a regular schedule. The amount is set by the board and can be increased, reduced, or suspended.

Related: Equity, Dividend yield
Dividend yield

Annual dividends per share divided by the share price, expressed as a percentage. It shows the income return from a stock and helps compare it with other income-producing assets.

Related: Dividend, Bond
Bond

A loan made by an investor to an issuer, such as a government or company, that pays interest and repays principal at maturity. Bondholders rank ahead of shareholders for repayment.

Related: Coupon, Yield to maturity (YTM), Credit rating
Coupon

The interest payment a bond issuer promises to pay holders, usually a fixed percentage of face value paid periodically. The coupon is set at issuance and does not change with market prices.

Related: Bond, Yield to maturity (YTM)
Yield to maturity (YTM)

The total annualized return an investor earns by buying a bond at its current price and holding it to maturity, assuming coupons are reinvested. It links price, coupon, and time remaining.

Related: Bond, Coupon, Duration
Duration

A measure of a bond's price sensitivity to changes in interest rates, expressed in years. A higher duration means the price will move more when yields rise or fall.

Related: Interest rate risk, Yield to maturity (YTM)
Credit rating

An independent agency's assessment of a borrower's ability to repay debt, expressed on a letter scale from high to low quality. Lower ratings imply higher default risk and usually require higher yields.

Related: Bond, Credit spread
Credit spread

The extra yield a bond offers above a comparable risk-free government bond. It widens when investors perceive more default risk and narrows when confidence improves.

Related: Credit rating, Bond
Mutual fund

A pooled investment vehicle that collects money from many investors and invests it according to a stated mandate. Shares are typically bought and sold at the fund's end-of-day net asset value.

Related: Net asset value (NAV), Expense ratio, Index fund
Exchange-traded fund (ETF)

A pooled fund whose shares trade on an exchange throughout the day like a stock. Most track an index and generally carry low fees, though trading incurs brokerage costs and spreads.

Related: Index fund, Net asset value (NAV), Expense ratio
Index fund

A fund designed to replicate the performance of a market index rather than beat it. Low turnover and minimal research keep costs down, making it a common passive building block.

Related: Exchange-traded fund (ETF), Expense ratio, Efficient market hypothesis
Net asset value (NAV)

The value of a fund's assets minus its liabilities, divided by the number of shares outstanding. It is the per-share price investors pay or receive when trading with the fund.

Related: Derivative, Option, Leverage
Risk

The possibility that an investment's actual return will differ from what was expected, including loss of capital. It comes in many forms, such as market, credit, liquidity, and inflation risk.

Related: Volatility, Standard deviation, Diversification
Standard deviation

A statistical measure of how widely returns vary around their average. In finance it is a common gauge of total risk, with larger values indicating more dispersed outcomes.

Related: Volatility, Risk
Diversification

Spreading money across assets whose returns do not move in perfect lockstep, so losses in one area may be offset elsewhere. It reduces risk without necessarily sacrificing expected return.

Related: Correlation, Risk, Asset allocation
Correlation

A measure from -1 to +1 of how closely two assets' returns move together. Combining assets with low or negative correlation improves diversification benefits.

Related: Diversification, Asset allocation
Asset allocation

The division of a portfolio among asset classes such as stocks, bonds, and cash. It is a primary driver of long-term risk and return and reflects an investor's goals and tolerance.

Related: Diversification, Risk tolerance
Risk tolerance

An investor's willingness and financial ability to accept losses or volatility in pursuit of returns. It is assessed through goals, time horizon, and capacity to absorb setbacks.

Related: Asset allocation, Suitability
Benchmark

A reference index or standard used to judge an investment's performance and risk. A well-chosen benchmark matches the portfolio's mandate, asset class, and region.

Related: Active management, Index fund
