This study provides formal theoretical evidence that constructions of fund alpha that are implemented using robust specifications of asset pricing models generate alpha estimates that are well defined. Regardless, the formal theoretical model shows fund alphas that are constructed with the...

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...

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...
