studied all 203 actively managed mutual funds with at least $100 million in assets, tracking their returns for the 15 years from 1984 through 1998. And you know what he found? Only 8 of these 203 funds actually beat the S&P 500 index. That’s less than 4%! To put it another way, 96% of these actively managed funds failed to add any value at all over 15 years!
