How Alumni Networks Relate to Chinese Hedge Fund Performance

Summary

This research review examines whether education ties among Chinese hedge fund managers are associated with fund performance. It builds time-varying networks in which funds are connected when their managers share a school and a similar field of study, then measures network position through degree, betweenness, closeness, and clustering. The analysis uses Chinese hedge fund data spanning 2010–2019 and evaluates risk-adjusted returns with panel regressions and fund-level controls.

The reported findings associate greater centrality with better risk-adjusted performance, while a higher clustering measure is associated with worse performance. The proposed mechanism is that central managers gain useful information and adopt more active investment styles; the review also reports a negative relationship between network position and fund flows. Effects vary by fund strategy, and the authors report robustness checks using alternative return measures and sampling frequencies. These are observational findings from one market and a particular network construction, so they do not establish that alumni ties cause stronger returns; the source also notes data and portfolio-detail limitations.

Key ideas

• The study defines strong alumni ties using shared schools and similar fields of study.
• It measures fund network position with three centrality metrics and a clustering coefficient.
• Greater centrality is associated with stronger risk-adjusted returns, while clustering is negatively associated.
• The proposed pathway runs from network position through more active investment style to performance.
• Reported effects differ across fund strategies, and the Chinese sample limits generalization.
