Each year, Dimensional analyzes investment returns from a large sample of US-domiciled funds (over 4,000). This year’s study updates results through 2022 and includes returns from mutual funds and exchange-traded funds (ETFs) domiciled in the US. 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 when making investment decisions.
