- Investment Policy Statement (IPS)
- Related: Risk Tolerance, Asset Allocation, Rebalancing
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.
- Risk Tolerance
- Related: Investment Policy Statement (IPS), Risk Aversion, Time Horizon
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.
- Risk Aversion
- Related: Risk Tolerance, Risk Premium, Utility Function
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.
- Time Horizon
- Related: Risk Tolerance, Liquidity Needs, Asset Allocation
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.
- Liquidity Needs
- Related: Time Horizon, Investment Policy Statement (IPS)
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.
- Asset Allocation
- Related: Strategic Asset Allocation, Tactical Asset Allocation, Diversification
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.
- Strategic Asset Allocation
- Related: Asset Allocation, Tactical Asset Allocation, Policy Benchmark
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.
- Tactical Asset Allocation
- Related: Strategic Asset Allocation, Market Timing, Active Management
Short-term, deliberate deviations from the strategic mix, made to exploit expected relative performance among asset classes, sectors, or markets.
- Rebalancing
- Related: Strategic Asset Allocation, Asset Allocation, Transaction Costs
Periodically buying and selling to restore a portfolio's asset weights to their target levels after market moves have pushed them away.
- Diversification
- Related: Correlation, Systematic Risk, Unsystematic Risk
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.
- Correlation
- Related: Diversification, Covariance, Efficient Frontier
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.
- Covariance
- Related: Correlation, Portfolio Variance
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.
- Systematic Risk
- Related: Unsystematic Risk, Beta, Diversification
Risk from broad market or economic forces that affects nearly all securities and cannot be removed by diversification, also called market risk.
- Unsystematic Risk
- Related: Systematic Risk, Diversification
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.
- Beta
- Related: Systematic Risk, Capital Asset Pricing Model (CAPM)
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.
- Capital Asset Pricing Model (CAPM)
- Related: Beta, Risk Premium, Security Market Line
A model stating that expected return equals the risk-free rate plus beta times the market risk premium, so only systematic risk is compensated.
- Risk-Free Rate
- Related: Risk Premium, Capital Asset Pricing Model (CAPM)
The return on a default-free investment, typically a short-term government security, used as the base rate from which risk premiums are added.
- Risk Premium
- Related: Risk-Free Rate, Risk Aversion, Capital Asset Pricing Model (CAPM)
The extra expected return investors demand for holding a risky asset instead of a risk-free one; it compensates for bearing uncertainty.
- Security Market Line
- Related: Capital Asset Pricing Model (CAPM), Beta, Alpha
A graph of expected return versus beta under CAPM; assets above the line appear undervalued for their risk, assets below it appear overvalued.
- Efficient Frontier
- Related: Correlation, Portfolio Variance, Optimal Portfolio
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.
- Optimal Portfolio
- Related: Efficient Frontier, Utility Function, Risk Aversion
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.
- Utility Function
- Related: Risk Aversion, Optimal Portfolio
A formula that scores the satisfaction an investor gets from a given risk-and-return combination, letting analysts rank portfolios for that investor.
- Portfolio Variance
- Related: Covariance, Correlation, Standard Deviation
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.
- Standard Deviation
- Related: Portfolio Variance, Volatility
The square root of variance, expressing how widely returns scatter around their average; it is the most common measure of total portfolio risk.
- Volatility
- Related: Standard Deviation, Value at Risk
The tendency of an asset's price or return to fluctuate over time, usually quantified by standard deviation or variance of returns.
- Value at Risk (VaR)
- Related: Volatility, Downside Risk
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.
- Downside Risk
- Related: Value at Risk (VaR), Sortino Ratio
Risk measured only from losses below a target or minimum acceptable return, rather than from all fluctuations in returns.
- Active Management
- Related: Passive Management, Tracking Error, Alpha
A strategy in which the manager deliberately deviates from a benchmark through security selection, weighting, or timing in an effort to outperform it.
- Passive Management
- Related: Active Management, Index Fund, Tracking Error
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.
- Index Fund
- Related: Passive Management, Expense Ratio
A pooled fund built to replicate the performance of a specified market index, typically charging low fees because it requires little research or trading.
- Growth Investing
- Related: Value Investing, Style Box
A style that buys companies expected to grow earnings or revenue faster than average, often accepting high valuations in exchange for that growth.
- Value Investing
- Related: Growth Investing, Style Box
A style that buys stocks trading below their estimated intrinsic worth, using measures such as low price-to-earnings or price-to-book ratios.
- Style Box
- Related: Growth Investing, Value Investing
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.
- Market Timing
- Related: Tactical Asset Allocation, Active Management
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.
- Benchmark
- Related: Policy Benchmark, Tracking Error, Alpha
A standard index or reference portfolio against which an investment's performance and risk are measured to judge whether the manager added value.
- Policy Benchmark
- Related: Strategic Asset Allocation, 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.
- Tracking Error
- Related: Active Management, Information Ratio, Benchmark
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.
- Alpha
- Related: Beta, Information Ratio, Security Market Line
The portion of return not explained by exposure to the benchmark or market, often interpreted as the value added or lost by active management.
- Information Ratio
- Related: Tracking Error, Alpha
Excess return over the benchmark divided by tracking error; it measures how much active return a manager earns per unit of active risk taken.
- Sharpe Ratio

Excess return over the risk-free rate divided by standard deviation of returns; it measures reward per unit of total risk.
- Treynor Ratio
- Related: Beta, Sharpe Ratio, Systematic Risk
Excess return over the risk-free rate divided by beta; it measures reward per unit of systematic risk and suits well-diversified portfolios.
- Sortino Ratio
- Related: Downside Risk, Sharpe Ratio
Excess return over a target return divided by downside deviation; it penalizes only harmful volatility, not upside gains.
- Time-Weighted Return
- Related: Money-Weighted Return, Benchmark
A return that chains subperiod growth rates to remove the effect of external cash flows, making it the standard for judging manager performance.
- Money-Weighted Return

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.
- Tax Efficiency
- Related: Turnover, Investment Policy Statement (IPS)
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.
