Dimensional’s 2019 analysis of US-based mutual funds shows that only a small percentage of funds have outperformed their primary benchmarks after costs—and among those who have had good results, only a small percentage have repeated their past success.

For years, we’ve been sharing the results of Dimensional Fund Advisors’ annually updated “Mutual Fund Landscape” analysis.  As we first expressed back in 2013, “This analysis of the US mutual fund industry performance casts doubt on the ability of investors to form a winning long-term strategy by picking outperforming funds based on past returns. It also raises questions about the effectiveness of investment strategies that attempt to add value by identifying mispriced securities.”

This is one message that bears repeating. Especially since, this year, somebody got creative over at Dimensional and produced an engaging video version. Check it out!
