Proof of black scholes formula
WebThe Black–Scholes formula calculates the price of European put and call options. This price is consistent with the Black–Scholes equation. This follows since the formula can be obtained by solving the equation for the corresponding terminal and boundary conditions : Web1 Answer Sorted by: 1 The equation d S ( t) = r S ( t) d t + σ S ( t) d W ( t) is not the Black-Scholes formula. It is a stochastic differential equation for geometric Brownian motion, which is one of the assumptions made in the derivation of the Black-Scholes-Merton pricing formula for an option.
