Modeling Stock Return Distributions and Pricing Options

Mathematical Finance 2025-03-12 v1

Abstract

This paper provides evidence that stock returns, after truncation, might be modeled by a special type of continuous mixtures or normals, so-called qq-Gaussians. Negative binomial distributions might model the counts for extreme returns. A generalized jump-diffusion model is proposed, and an explicit option pricing formula is obtained.
