Theoretical models imply fund size and performance should be negatively linked. However, empiricists have failed to uncover consistent support for this negative relation. Using a new econometric framework which includes fund-specific sensitivities to decreasing returns to scale, we find a both...

Positive return correlation signals slowly-diffusing information. Short sell-constrained institutions are mainly informed in their buy trades. Building on these facts, we identify informed investors ex ante by focusing on mutual funds. We propose a measure of the dynamic excess autocorrelation...

We examine manager performance across multiple contemporaneously-managed mutual funds and document significant cross-sectional performance persistence. While 80% of managers in our sample have at least one underperforming fund in each quarter, a small but statistically significant number of...

We investigate the information source of active U.S. equity mutual funds’ value added using 234 public asset pricing anomalies. On average, mutual funds add value through their positive exposures to anomalies based on market information (e.g., momentum and liquidity risk) and lose value...

We examine the relative weights hedge fund investors attach to past information in the fund selection process. The weighting scheme appears inconsistent with the one of econometric forecast models that predict fund returns, alphas or Sharpe ratios. In particular, investor flows are highly...

We propose a new definition of skill as a general cognitive ability to either pick stocks or time the market at different times. We find evidence for stock picking in booms and for market timing in recessions. Moreover, the same fund managers that pick stocks well in expansions also time the...

We analyze the dispersion of month-end prices simultaneously placed on identical corporate bonds by different US mutual fund managers before and after initiations of TRACE and introductions of issuers into Markit's CDS database. Disseminated bonds show large and statistically significant...

This study shows that exchange-traded fund (ETF) misvaluation — based on return differentials between ETFs and their net asset values (NAV) — comove excessively across ETFs. Excess comovements are positive (negative) and significant across ETFs in similar (distant) investment styles. Further...

We provide novel evidence supporting the notion that arbitrageurs can contribute to return comovement via ETF arbitrage. Using a large sample of U.S. equity ETF holdings, we document the link between measures of ETF activity and return comovement at both the fund and the stock levels, after...

We develop a principal-agent model based on a sequential game played by a representative investor and a fund manager in an asymmetric information framework. The model shows that investors' perceptions of the fund market play the key role in the fund's fee-setting mechanism. The managers' true...
