SUMMARY OF RESULTS
- When it comes to the active versus passive debate, one of the key measurements of successful active management lies in the ability of a manager or a strategy to deliver above-average returns consistently over multiple periods. Demonstrating the ability to outperform peers repeatedly is the one way to differentiate a manager’s luck from skill.
- According to the S&P Persistence Scorecard, relatively few funds can consistently stay at the top. Out of 557 domestic equity funds that were in the top quartile as of March 2016, only 2.33% managed to stay in the top quartile at the end of March 2018. Furthermore, 0.93% of the large-cap funds, no mid-cap funds, and 3.85% of the small-cap funds remained in the top quartile.
- For the three-year period that ended in March 2018, persistence figures for funds in the top half were also unfavorable. Over three consecutive 12-month periods, 21.96% of large-cap funds, 7.59% of mid-cap funds, and 13.46% of small-cap funds maintained a top-half ranking.
- An inverse relationship generally exists between the measurement time horizon and the ability of top-performing funds to maintain their status. It is worth noting that only 0.45% of large-cap and no midcap or small-cap funds managed to remain in the top quartile at the end of the five-year measurement period. Furthermore, no mid-cap or small-cap funds were able to retain their status as of the end of the fourth 12-month period. This figure paints a negative picture regarding long-term persistence in mutual fund returns.
- Similarly, only 11.41% of large-cap funds, 1.2% of mid-cap funds, and 3.57% of small-cap funds maintained top-half performance over five consecutive 12-month periods. Random expectations would suggest a repeat rate of 6.25%.
- The transition matrices are designed to track the performance of top- and bottom-quintile performers over subsequent time periods. The data show a stronger likelihood for the bestperforming funds to become the worst-performing funds than vice versa. Of 364 funds that were in the bottom quartile, 17.03% moved to the top quartile over the five-year horizon, while 25.82% of the 364 funds that were in the top quartile moved to the bottom quartile during the same period.
- Our research also suggests that there is consistency in the death rate of bottom-quartile funds. Across all market cap categories and all periods studied, fourth-quartile funds had a much higher rate of being merged or liquidated. The five-year transition matrix shows that 33.83% of large-cap funds, 33.96% of mid-cap funds, and 29.07% of small-cap funds in the fourth quartile disappeared.
- Compared with domestic equity funds, there was a higher level of performance persistence among the top-quartile fixed income funds over the three-year period ending March 2018. Government Intermediate, Global Income, and Emerging Markets funds were the only categories in which the results showed no performance persistence.
- Over the five-year measurement horizon, the results show a lack of persistence among nearly all the top-quartile fixed income categories, with a few exceptions. Funds investing in long-term government and investment-grade bonds, short-term investment-grade bonds, mortgagebacked securities, general municipal debt, and California municipal debt were the only groups in which a noticeable level of persistence was observed.
