Failure Risk and the Cross‐Section of Hedge Fund Returns

Modeling a hedge fund's probability of failure with a dynamic logit regression, I find that the probability of a fund's failure has a significantly negative effect on the fund's future returns. A quintile portfolio with the highest failure probability underperforms a quintile portfolio with the lowest failure probability by 5% to 6% per year from 1997 to 2012. The results are robust to the definition of hedge fund failure and controlling for a large set of risk factors and fund characteristics. Moreover, the negative effect of failure probability on future fund returns is stronger for funds with weak share restrictions.     

国际对冲基金监管制度比较研究与启示

对冲基金近年发展迅猛,各国根据本国国情初步建立了监管制度。本文认为应从改进治理结构、强化自律监管,加强市场约束、提高透明度等方面,沿运营流程和主要运营当事人两条线索完善对冲基金现有监管法律制度。在金融市场全面开放背景下,我国应在放开私募管制基础上根据市场和金融产品发展进程推进对冲基金逐步合法化。     

On the High‐Frequency Dynamics of Hedge Fund Risk Exposures

We propose a new method to model hedge fund risk exposures using relatively high‐frequency conditioning variables. In a large sample of funds, we find substantial evidence that hedge fund risk exposures vary across and within months, and that capturing within‐month variation is more important for hedge funds than for mutual funds. We consider different within‐month functional forms, and uncover patterns such as day‐of‐the‐month variation in risk exposures. We also find that changes in portfolio allocations, rather than in the risk exposures of the underlying assets, are the main drivers of hedge funds' risk exposure variation.     

Luck versus Skill in the Cross‐Section of Mutual Fund Returns

The aggregate portfolio of actively managed U.S. equity mutual funds is close to the market portfolio, but the high costs of active management show up intact as lower returns to investors. Bootstrap simulations suggest that few funds produce benchmark‐adjusted expected returns sufficient to cover their costs. If we add back the costs in fund expense ratios, there is evidence of inferior and superior performance (nonzero true α) in the extreme tails of the cross‐section of mutual fund α estimates.
