The relationship between political connections and the mutual fund performance: Evidence from the US

Abstract This paper examines the effect of political connections between mutual fund managers and politicians on the fund performance. Using the publicly available data of individual political donations, we regard the mutual funds as politically connected when their managers make financial contributions to politicians. First, we show that aggregated stock holding changes of politically connected funds predict subsequent abnormal stock returns around the earnings announcement day, implying that the political connection promotes managers’ stock picking abilities. Further evidence derived from the sample of entry buys and exit sells shows that politically connected funds outperform politically non-connected funds by 82 basis points annually. Second, we provide evidence that earnings forecast accuracy for the firms whose stocks are held by politically connected funds is improved significantly when time is approaching the announcement date, highlighting the importance of political channels through which information flows between firms and the market are facilitated.
