Despite its widespread use in equity pricing modeling, by hypothesis, the Black Scholes model (like other diffusion models) has limitations that don’t allow it to capture some typical market behaviors. Due this fact, several authors have proposed that stock prices follow a pure jump models and their modeling is structured by a Lévy process. In this context, this paper shows a study on the options pricing using a model developed by Madan and Seneta (1990) which is based on pure jumps process known as variance gamma (VG). This work presents the study of two new curves plotted from the variance gamma model in addition to the classical volatility smile curve. Together these three curves can be used as tools to better explain the behavior of asset prices. As database were used Brazilian historical stocks e options prices.
