Benchmarks are used to determine relative performance of portfolios and securities. They are particularly useful in evaluating mutual funds and money managers. Morningstar and Lipper Analytical Services are two of the many services that track and analyze mutual fund performance. Many investment consultants also evaluate money managers and funds vis-a-vis benchmarks and other money managers and funds.
Commonly used benchmarks for measuring US stock returns are the Wilshire 5000 for the broad market, the S&P 500 for large capitalization stocks, and the Russell 2000 for small stocks. Morgan Stanley's EAFE is commonly used for Global stocks.
Generally, experts recommend using benchmarks that are unambiguous, investable (using a median is not an investable option), measurable, specified in advance, and are appropriate and consistent with the managers style. Still, investors should be aware that performance evaluation has two basic problems.
- Many observations are needed for significant results.
- Shifting parameters during active management complicate performance valuation.
In addition to returns, its often helpful to analyze risk measures. The following are commonly used risk adjusted performance measures.
Trivia Answer: 70 years
- The Sharpe Ratio (developed by William F. Sharpe) divides average portfolio excess return by the standard deviation of returns for the period. It measures reward to total volatility.
- Treynor's measure uses systematic risk (Beta) instead of total risk.
- Jensen's measure is the alpha or the total return less the return predicted by the Capital Asset Pricing Model (CAPM).
