Each year, Dimensional analyzes returns from a large sample of US-based mutual funds. Our objective is to document the power of market prices by assessing fund manager performance relative to index benchmarks. This year’s study updates results through 2016. The evidence shows that a majority of fund managers in the sample failed to deliver benchmark-beating returns after costs.
We believe that the results of this research provide a strong case for relying on market prices.
Using a representative sample of US-domiciled mutual fund returns from Morningstar, the report documents the power of market prices by assessing fund returns over multiyear periods. The exhibits include data visualizations of fund survivorship and outperformance, persistence of top-quartile funds, and the impact of high fees and turnover on manager performance.
