摘要

In Figueroa-Lopez et al. (Math. Finance, 2013), a second order approximation for at-the-money option prices is derived for a large class of exponential Levy models, with or without a Brownian component. The purpose of the present article is twofold. First, we relax the regularity conditions imposed on the Levy density to the weakest possible conditions for such an expansion to be well defined. Second, we show that the formulas extend both to the case of "close-to-the-money" strikes and to the case where the continuous Brownian component is replaced by an independent stochastic volatility process with leverage.
