Cover Story: The risk premium of a European call option is defined as the relative difference in expected payoff under the P- and Q-probability measures. An option is regarded as (in)expensive when it bears a (positive) negative risk premium. In this work, we focus on options with a zero-risk premium, defined by the so-called zero-risk premium strike. This strike indicates the transition point from which call options are considered expensive. In order to calculate this zero-risk premium strike, pricing and physical distributional information on the return of the underlying asset is needed. We simultaneously extract this information from options data using a tilted bilateral gamma model. View this paper
