Mutual funds are now the preferred way for individual investors and ma
ny institutions to participate in the capital markets, and their popul
arity has increased demand for evaluations of fund performance. Many b
usiness publications now rank mutual Amds according to their performan
ce, and information sen ices exist specifically for this purpose. Ther
e is no general agreement, however, about how best to measure and comp
are fund performance and on what information funds should disclose to
investors. Risk and performance measurement is an active area for acad
emic research and continues to be of vital interest to investors who n
eed to make informed decisions and to mutual fund managers whose compe
nsation is tied to performance. This article describes a number of per
formance measures. Their common feature is that they all measure funds
' returns relative to risk. However, they differ in how they define an
d measure risk and, consequently, in how they define risk-adjusted per
formance. The author also compares rankings of a large sample of funds
using two popular measures. She finds a surprisingly good agreement b
etween the two measures for both stock and bond funds during the three
-year period between 1995 and 1997.
