This paper derives accurate inferences about the contribution of a high-dimensional set of option and stock characteristics to the cross-sectional variation in delta-hedged option returns. Unlike the extant literature that is largely focused on the construction of predictive models, we apply...

Professional asset allocators frequently report positive alphas, and the generation of alpha is widely discussed in the context of asset allocation. This paper demonstrates that two-fund asset allocation strategies contain a positive-alpha bias and derives an expression for the alpha of an asset...

This paper evaluates the underperformance of individual equity options relative to their replicating portfolios. Considering a high-dimensional set of variables, we use a machine learning approach to identify the characteristics of options and their underlying stocks that provide incremental...
