Abstract
Which market has leading informational advantage: stocks or options? Using large set of stock
and option characteristics, and machine learning, we provide a comprehensive analysis of which
characteristics are the first order importance predictors of option and stock returns. First, we find
that option, rather than stock, characteristics are dominant predictors of option returns. Second, option, rather than stock, characteristics are also dominant predictors of stock returns. Consistent with the argument that an increase in trading activity in derivatives decreases information asymmetry about the underlying, option illiquidity is identified as the most important predictor of both stock and option
returns.
