摘要
This survey of the literature on the value of active management shows that the average active manager does not outperform but that a significant minority of active managers do add value. Further, studies suggest that investors may be able to identify superior active managers (SAMs) in advance by using public information. Investors who can identify SAMs should be able to improve their overall Sharpe ratio by including a meaningful exposure to active strategies.
