We explore performance persistence in mutual funds using absolute and relative benchmarks. Our sample, largely free of survivorship bias, indicates that relative risk-adjusted performance of mutual funds persists, however persistence is mostly due to funds that lag the S&P 500. A probit analysis indicates that poor performance increases the probability of disappearance. A year-by-year decomposition of the persistence effect demonstrates that the relative performance pattern depends upon the time period observed, and it is correlated across managers. Consequently, it is due to a common strategy that is not captured by standard stylistic categories, or risk adjustment procedures.
