This study provides early evidence on the performance of passively-managed hedged exchange-traded funds (HETFs) introduced rather recently in late 2006. The data covers surviving HETFs in 2017 under global macro and long-short classifications. Using Fung and Hsieh's (2004) 7-factor model and...

We give an explicit algorithm and source code for combining alpha streams via bounded regression. In practical applications, typically, there is insufficient history to compute a sample covariance matrix (SCM) for a large number of alphas. To compute alpha allocation weights, one then resorts to...

We give a simple explicit formula for turnover reduction when a large number of alphas are traded on the same execution platform and trades are crossed internally. We model turnover reduction via alpha correlations. Then, for a large number of alphas, turnover reduction is related to the largest...
