WebOne of the limitations of using the Black-Scholes model is the assumption of a constant volatility s in (2), (4). A major modeling step away from the assumption of constant volatility in asset pricing, was made by modeling the volatility/variance as a diffusion process. The resulting models are the stochastic volatility (SV) models.
