When performance is measured by Jensen's alpha, mutual funds that perform well in a one year evaluation period continue to generate superior performance in the following year.

The timing component -- knowing when to pick which fund -- is significant. These results are robust to alternative equity portfolio benchmarks, such as those that account for firm-size effects and mean reversion in returns. Capitilizing on the hot hands phenomenon, an investor could have generated a significant, risk-adjusted exc...
