Abstract

This study investigates the effect of competition networks among hedge fund managers on strategy distinctiveness and fund performance. Using a sample of 2711 US‐based hedge funds from the Lipper TASS database between 1994 and 2018, we construct a hedge fund competition network (HFCN) based on alumni and employment ties derived from LinkedIn profiles. We find that greater centrality in the HFCN, indicating closer proximity to peer competitors, is associated with lower abnormal performance. This effect is partially mediated by a decline in strategy distinctiveness, measured by the Strategy Distinctiveness Index (SDI). Funds with stronger network ties tend to exhibit greater return similarity with peers, suggesting that social proximity encourages strategic conformity. The results are robust across performance metrics, style classifications, and subsamples and are particularly pronounced among managers with strong cognitive profiles.
