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...

We provide the first in-depth examination of exchange-traded funds (ETFs) within actively managed mutual fund (AMMF) portfolios to better understand why AMMFs make substantial investments in passive ETFs. We examine the association between holding ETF positions and AMMF performance, as well as...

We investigate the relationship between a mutual fund's variation in factor exposures and its future performance. Using a dynamic state space version of Carhart (1997)'s four factor model to capture factor variation, we find that funds with volatile factor exposures underperform funds with...

Why do investors entrust active mutual fund managers with large sums of money while receiving negative excess returns on average? Our explanation is that investors have a coarser information set than fund managers which leads them to systematically misinterpret managers' skill. When investors...

We investigate the relationship between a mutual fund’s variation in systematic risk factor exposures and its future performance. Using a dynamic state space version of Carhart (1997)’s four factor model to capture risk factor variation, we find that funds with volatile risk factor exposures...

Active fund managers are skilled and, on average, have used their skill to generate about $3.2 million per year. Large cross-sectional differences in skill persist for as long as ten years. Investors recognize this skill and reward it by investing more capital in funds managed by better...

Performance regressions lever expected benchmark returns linearly to the risk exposures of the fund. The interest rate (IR) risk premium, however, usually follows a decreasingly upward-sloping yield curve, characterizing the nonlinearity between expected return and IR risk exposure, e.g....

This paper revisits the performance of European mutual funds using a more recent and extensive survivorship bias free database of 16,055 equity funds over the 1992-2006 period. Earlier evidence by Otten & Bams (2002) pointed to an exceptional position of European mutual funds. In sharp contrast...

We study the interdependencies between transaction costs, portfolio characteristics, and mutual fund performance. Using a novel dataset of actual mutual fund trades, we find that, controlling for investment style, larger funds realize lower percentage transaction costs than smaller funds. Larger...

This study analyzes the motives for and consequences of funds' credit default swap (CDS) investments using mutual funds' quarterly holdings from pre- to post-financial crisis. Funds resort to CDS investment when facing unpredictable liquidity needs. Funds sell more in reference entities where...
