Whether we consider academic studies (many of which, I presume, included tests of predicting future returns that were found wanting and were never published), or the pragmatic and unforgiving actual results of the funds with the best long-term records, or the picks of fund advisory services, or records of funds of funds, the odds of selecting mutual funds that are top performers in the future have proved extremely poor. The chances that individual fund investors will find the holy grail that will identify in advance the future’s superior performers seem equally dismal.
