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...

Commodity trading advisors (CTAs) make directional investments in liquid futures and forward markets. Since CTAs generally do not engage in security selection or relative value trades, their performance depends to a large extent on funds ability to time market exposures. We analyze CTA return...

Using a novel database, the NilssonHedge hedge fund database covering more than 350,000 return observations, we perform a large-scale multiple regression. We evaluate alpha against the Fama French five-factor model including momentum. Our findings are compatible with a net-zero alpha from hedge...
