U.S. mutual funds participating in the securities lending market extract information from stock borrowing. Active mutual funds exploit this information for trading and rebalance their portfolios away from borrowed stocks, whereas passive funds do not. This rebalancing avoids capital losses on borrowed stocks whose prices tend to decrease. Active funds also trade more aggressively on stocks with more negative future returns, suggesting that they are able to identify informed borrowing. Finally, passive funds charge higher lending fees than active funds, consistent with short sellers paying a premium to lenders who do not exploit the information revealed by stock borrowing.
