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. Webtherefore implies that the local volatility model of (1) is in some sense the simplest diffusion model capable of doing this, i.e. reproducing the implied volatility surface. Gy¨ongy’s Theorem has been used recently to develop stochastic-local volatility models as well as approximation techniques for pricing various types of basket options.
