For Better or Worse? Mutual Funds in Side-By-Side Management Relationships With Hedge Funds

Abstract:     
Firms that engage in the simultaneous, or "side-by-side", management of mutual funds and hedge funds have a fiduciary duty to each fund's investors to make portfolio decisions and to execute trades in the most favorable way. This fiduciary duty is put to the test, however, when side-by-side management firms can increase fee income by strategically transferring performance from the mutual funds to the hedge funds they oversee. Our empirical evidence proves consistent with such favoritism. The reported returns of side-by-side mutual funds are significantly less than those of similar mutual funds run by firms that do not also manage hedge funds. A decomposition of reported returns into holdings-return and return-gap components and return-persistence tests also suggest favoritism. Finally, examining a potential wealth transference mechanism, we find evidence consistent with side-by-side mutual funds getting less of a contribution to performance from IPO underpricing than matched unaffiliated mutual funds.
