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. dallas city council meeting recordingsWebJun 8, 2024 · The local volatility of the underlying assets is a deterministic function of assets price and the time t. σ= σ(St,t) σ = σ ( S t, t) Therefore with the local volatility model, the stochastic process followed by the stock price is. dSt = μSt dt+ σ(St,t)dW t d S t = μ S t d t + σ ( S t, t) d W t.
