Deriving black scholes formula
WebFrom the binomial tree with drift equation (1), we could guess that dSt St = µdt+σdW (2) is a reasonably similar model. In fact, this model is the continuous time analogue of the binomial tree. 7. To derive the Black-Scholes PDE, we will need the dynamics of (2) we just stated. We will also find that we need to take differentials of functions, WebThis entry derives the Black-Scholes formula in martingale form. The portfolio process Vt representing a stock option will be shown to satisfy: Vt = e - r ( T - t) 𝔼ℚ[VT ∣ ℱt]. (1) (The quantities appearing here are defined precisely, in the section on “ Assumptions ” below.)
