Dr Jose Fajardo : In my paper we study the skewness premium observed in option prices when the undelying asset returns follows a Levy Processes. In this way we obtain a simple diagnostic to judge what Levy models explain the behaviour observed in option prices.

The main contribution of this paper is the characterization of symmetry in these market models, a notion that is also introduced.

This characterization allows to introduce a parameter in the risk neutral model that, in certain sense, measures the asymmetry of a Levy market model.
