Abstract

I document portfolio pumping at the fund family level, a strategy that non-star fund managers buy stocks held by star funds in the family to inflate their performance at the quarter end. Families that heavily employ the strategy show strong evidence of inflated performance after 2002, when the SEC increased regulation on portfolio pumping at the fund level. Moreover, non-star fund managers who help pump the star funds in the family receive 1.8% ($24 million) more inflows per quarter, conditional on the performance. Furthermore, managers pump small stocks that are buried deep down in the holdings of star funds.
