Do Prime Brokers Matter in the Search for Informed Hedge Fund Managers?
利用对冲基金的基金（FoFs）数据，研究发现主经纪商（PBs）帮助投资者寻找知情对冲基金经理，FoFs表现出对关联PB服务基金的偏好，且这种偏好能预测业绩，最高偏好组年化超额收益达2.08%-2.45%。
Using the setting of funds of hedge funds (FoFs), we show that prime brokers (PBs) facilitate investors’ search for informed hedge fund managers. We find that FoFs exhibit PB bias, a disproportionate preference for hedge funds serviced by their connected PBs. This PB bias is stronger when the cost of hedge fund due diligence is higher relative to capital and when the FoF’s management firm generates higher prime brokerage fees. PB bias also predicts FoF performance: the highest PB-bias quartile outperforms the rest by 2.08%–2.45% per annum after adjusting for differences in their risks.
