We examine how active share—the extent to which a portfolio's holdings differ from its benchmark's holdings—affects the performance, risk management, and flows of bond mutual funds. Measuring active share at both the issue and issuer level, the average bond fund has an issue-level...

Just over 20 years have passed since the publication of Carhart's landmark 1997 study on mutual funds. Its conclusion—that the data did “not support the existence of skilled or informed mutual fund portfolio managers”—was the capstone of an academic literature beginning with Jensen...
