We develop a stock return-predictive measure based on an efficient aggregation of the portfolio holdings of all actively managed U.S. domestic equity mutual funds, and use this model to study the source of fund managers' stock-selection abilities. This "generalized-inverse alpha" (GIA) approach...

This study applies an innovative return-based approach to determine the style-shifting activity of mutual funds. Based on daily returns, we measure style-shifting activity as inter-quarterly changes in the style exposures of a fund. In order to test the robustness of style-shifting activity we...

We analyze the out-of-sample performance of variables shown to forecast future mutual fund alphas. The degree of predictability, as measured by alpha spreads from quintile sorts or by cross-sectional regression slopes, falls by at least half post-sample. These declines appear to be primarily the...

This paper builds on recent empirical studies that document the general impact of analyst recommendations on mutual fund trading. We argue that the use of analyst research might be a strategic decision depending on the type of mutual fund. Therefore, we identify the funds that trade in...

A great deal of research effort has sought to understand whether fund managers have skill. However, most of this research draws inferences from fund returns attributable to funds that may have been managed by many different managers over the years. In this paper we focus on the fund manager. We...

We propose and test a methodological framework to examine the relation between mutual fund fees and return predictability. Gil-Bazo and Ruiz-Verdu (2009) drew attention to the puzzling fact that funds with worse before-fee performance charge higher fees. We make another contribution to the...

This paper studies the effect of Morningstar ratings on fund flows and fund performance predictability using a proprietary data set of equity funds from Norway. Controlling for a number of variables proxying for fund and firm visibility, we find that fund flows respond asymmetrically to changes...
