The Unassuming Economist

According to Mark Perry of Carpe Diem: “over the last 15 years from June 30, 2003 to June 30, 2018, only one in 13 large-cap managers, only one in 21 mid-cap managers, and one in 43 small-cap managers were able to outperform their benchmark index. So it is possible for some active fund managers to “beat the market” over various time horizons, although there’s no guarantee that they will continue to do so in the future. And the percentage of active managers who do beat the market is usually pretty small – fewer than 8% in most of the cases above over the last 15 years; and they may not sustain that performance in the future.”
