Investment Policy Statement (IPS)

A written document that sets a client's return objective, risk tolerance, time horizon, liquidity needs, tax situation, legal constraints, and unique circumstances, and the rules for managing the portfolio in line with them.

Related: Risk Tolerance, Asset Allocation, Rebalancing
Risk Tolerance

The degree of variability in returns, and the chance of loss, that an investor is both financially able and psychologically willing to accept while pursuing objectives.

Related: Investment Policy Statement (IPS), Risk Aversion, Time Horizon
Risk Aversion

An investor's reluctance to accept additional uncertainty in returns; a more risk-averse investor demands a larger expected return premium to hold riskier assets.

Related: Risk Tolerance, Risk Premium, Utility Function
Time Horizon

The length of time over which an investor's money will be invested before it is needed; longer horizons generally allow more equity exposure and more tolerance for short-term volatility.

Related: Risk Tolerance, Liquidity Needs, Asset Allocation
Liquidity Needs

The amount of cash or readily sellable assets an investor must keep available to meet anticipated or emergency spending without disrupting the long-term portfolio strategy.

Related: Time Horizon, Investment Policy Statement (IPS)
Asset Allocation

Dividing a portfolio among broad asset classes such as cash, bonds, equities, and real assets, usually in proportions chosen to balance expected return against risk.

Related: Strategic Asset Allocation, Tactical Asset Allocation, Diversification
Strategic Asset Allocation

The long-term target mix of asset classes chosen to fit an investor's objectives and constraints; it is the benchmark against which tactical moves and manager results are judged.

Related: Asset Allocation, Tactical Asset Allocation, Policy Benchmark
Tactical Asset Allocation

Short-term, deliberate deviations from the strategic mix, made to exploit expected relative performance among asset classes, sectors, or markets.

Related: Strategic Asset Allocation, Market Timing, Active Management
Rebalancing

Periodically buying and selling to restore a portfolio's asset weights to their target levels after market moves have pushed them away.

Related: Strategic Asset Allocation, Asset Allocation, Transaction Costs
Diversification

Spreading money across assets whose returns do not move in lockstep, so that losses in one holding are partly offset by gains or stability in others.

Related: Correlation, Systematic Risk, Unsystematic Risk
Correlation

A measure from -1 to +1 of how closely two assets' returns move together; lower correlation between holdings produces greater diversification benefit for a given level of risk.

Related: Diversification, Covariance, Efficient Frontier
Covariance

A measure of how two assets' returns vary jointly; it feeds directly into portfolio variance calculations and captures both the size and direction of their co-movement.

Related: Correlation, Portfolio Variance
Systematic Risk

Risk from broad market or economic forces that affects nearly all securities and cannot be removed by diversification, also called market risk.

Related: Unsystematic Risk, Beta, Diversification
Unsystematic Risk

Risk specific to a single company or industry, such as a product failure or lawsuit; it can be largely eliminated by holding a diversified portfolio.

Related: Systematic Risk, Diversification
Beta

A measure of a security's or portfolio's sensitivity to movements in the overall market; a beta of 1 means it tends to move with the market, above 1 means more volatile.

Related: Systematic Risk, Capital Asset Pricing Model (CAPM)
Capital Asset Pricing Model (CAPM)

A model stating that expected return equals the risk-free rate plus beta times the market risk premium, so only systematic risk is compensated.

Related: Beta, Risk Premium, Security Market Line
Risk-Free Rate

The return on a default-free investment, typically a short-term government security, used as the base rate from which risk premiums are added.

Related: Risk Premium, Capital Asset Pricing Model (CAPM)
Risk Premium

The extra expected return investors demand for holding a risky asset instead of a risk-free one; it compensates for bearing uncertainty.

Related: Risk-Free Rate, Risk Aversion, Capital Asset Pricing Model (CAPM)
Security Market Line

A graph of expected return versus beta under CAPM; assets above the line appear undervalued for their risk, assets below it appear overvalued.

Related: Capital Asset Pricing Model (CAPM), Beta, Alpha
Efficient Frontier

The set of portfolios offering the highest expected return for each level of risk; portfolios below it are inefficient because more return is available for the same risk.

Related: Correlation, Portfolio Variance, Optimal Portfolio
Optimal Portfolio

The single point on the efficient frontier that best matches a particular investor's risk aversion, found where the highest attainable indifference curve touches the frontier.

Related: Efficient Frontier, Utility Function, Risk Aversion
Utility Function

A formula that scores the satisfaction an investor gets from a given risk-and-return combination, letting analysts rank portfolios for that investor.

Related: Risk Aversion, Optimal Portfolio
Portfolio Variance

A statistical measure of the dispersion of a portfolio's returns; it depends on each holding's variance and weight plus the covariances between every pair of holdings.

Related: Covariance, Correlation, Standard Deviation
Standard Deviation

The square root of variance, expressing how widely returns scatter around their average; it is the most common measure of total portfolio risk.

Related: Portfolio Variance, Volatility
Volatility

The tendency of an asset's price or return to fluctuate over time, usually quantified by standard deviation or variance of returns.

Related: Standard Deviation, Value at Risk
Value at Risk (VaR)

An estimate of the largest loss a portfolio is likely to suffer over a stated period at a stated confidence level, such as a one-day 95% VaR.

Related: Volatility, Downside Risk
Downside Risk

Risk measured only from losses below a target or minimum acceptable return, rather than from all fluctuations in returns.

Related: Value at Risk (VaR), Sortino Ratio
Active Management

A strategy in which the manager deliberately deviates from a benchmark through security selection, weighting, or timing in an effort to outperform it.

Related: Passive Management, Tracking Error, Alpha
Passive Management

A strategy that seeks to match a market index's return by holding the index constituents or a representative sample, with minimal trading and low costs.

Related: Active Management, Index Fund, Tracking Error
Index Fund

A pooled fund built to replicate the performance of a specified market index, typically charging low fees because it requires little research or trading.

Related: Passive Management, Expense Ratio
Growth Investing

A style that buys companies expected to grow earnings or revenue faster than average, often accepting high valuations in exchange for that growth.

Related: Value Investing, Style Box
Value Investing

A style that buys stocks trading below their estimated intrinsic worth, using measures such as low price-to-earnings or price-to-book ratios.

Related: Growth Investing, Style Box
Style Box

A grid that classifies investments by size (large, mid, small) and by style (value, blend, growth), used to compare a portfolio's positioning with its benchmark.

Related: Growth Investing, Value Investing
Market Timing

Attempting to move money in and out of markets or asset classes in anticipation of price changes, typically with poor long-run results after costs.

Related: Tactical Asset Allocation, Active Management
Benchmark

A standard index or reference portfolio against which an investment's performance and risk are measured to judge whether the manager added value.

Related: Policy Benchmark, Tracking Error, Alpha
Policy Benchmark

A custom benchmark built from the strategic asset allocation's index weights, used to separate the effects of policy choices from active management decisions.

Related: Strategic Asset Allocation, Benchmark
Tracking Error

The standard deviation of the difference between a portfolio's returns and its benchmark's returns; it gauges how closely the portfolio follows the benchmark.

Related: Active Management, Information Ratio, Benchmark
Alpha

The portion of return not explained by exposure to the benchmark or market, often interpreted as the value added or lost by active management.

Related: Beta, Information Ratio, Security Market Line
Information Ratio

Excess return over the benchmark divided by tracking error; it measures how much active return a manager earns per unit of active risk taken.

Related: Tracking Error, Alpha
Sharpe Ratio

Excess return over the risk-free rate divided by standard deviation of returns; it measures reward per unit of total risk.

Related: Risk-Free Rate, Standard Deviation, Treynor Ratio
Treynor Ratio

Excess return over the risk-free rate divided by beta; it measures reward per unit of systematic risk and suits well-diversified portfolios.

Related: Beta, Sharpe Ratio, Systematic Risk
Sortino Ratio

Excess return over a target return divided by downside deviation; it penalizes only harmful volatility, not upside gains.

Related: Downside Risk, Sharpe Ratio
Time-Weighted Return

A return that chains subperiod growth rates to remove the effect of external cash flows, making it the standard for judging manager performance.

Related: Money-Weighted Return, Benchmark
Money-Weighted Return

A return that reflects the size and timing of an investor's deposits and withdrawals, essentially the internal rate of return on the account.

Related: Time-Weighted Return
Attribution Analysis

Breaking down a portfolio's performance relative to a benchmark into sources such as asset allocation, security selection, and interaction effects.

Related: Benchmark, Alpha, Tracking Error
Expense Ratio

A fund's annual operating costs, including management fees and administration, expressed as a percentage of average net assets and deducted from returns.

Related: Index Fund, Transaction Costs
Transaction Costs

The costs of trading, including commissions, bid-ask spreads, and market impact, which reduce net returns and rise with more frequent trading.

Related: Expense Ratio, Rebalancing, Turnover
Turnover

The rate at which a portfolio's holdings are replaced over a period; high turnover usually means higher trading costs and potentially greater tax liability.

Related: Transaction Costs, Tax Efficiency
Tax Efficiency

Managing a portfolio so that taxes on dividends, interest, and realized gains are minimized, for example by holding assets in the most suitable account type.
