英文摘要:
We analyze empirical data for 4,000 real-life trading portfolios (U.S. equities) with holding periods of about 0.7-19 trading days. We find a simple scaling C ~ 1/T, where C is cents-per-share, and T is the portfolio turnover. Thus, the portfolio return R has no statistically significant dependence on the turnover T. We also find a scaling R ~ V^X, where V is the portfolio volatility, and the power X is around 0.8-0.85 for holding periods up to 10 days or so. To our knowledge, this is the only publicly available empirical study on such a large number of real-life trading portfolios/alphas.

中文摘要:
我们分析了4000个真实交易组合(美国股票)的经验数据,持有期约为0.7-19个交易日。我们发现了一个简单的标度C~1/T,其中C是每股美分,T是投资组合的周转率。因此,投资组合回报率R对交易额T没有统计上的显著依赖性。我们还发现了一个标度R~V^X,其中V是投资组合的波动率,对于10天左右的持有期,幂X约为0.8-0.85。据我们所知,这是对如此大量的真实交易组合/Alpha进行的唯一公开的实证研究。
