Portfolio concentration and mutual fund performance

Journal of Empirical Finance, 2019, vol. 51, issue C, 1-16

Abstract: Mutual fund managers should choose to increase their portfolio concentration when their information set is valuable enough that the benefits of the expected increase in alpha more than offsets the costs of the expected increase in idiosyncratic volatility. Consistent with that idea, we find that fund performance improves after concentration increases. Because the expected costs of increased concentration vary between funds and over time, the required expected benefits before managers choose to increase concentration should also vary. Among other results, we show that the concentration-performance relation is stronger for funds with less institutional ownership and when investor sentiment is low.
