finance - Proof of the Black - Scholes pricing formula for European ...
The Black–Scholes equation is a parabolic partial differential equation, which describes the price of the option over time. The equation is: A key financial insight behind the equation is that one can perfectly hedge the option by buying and selling the underlying asset and the bank account asset (cash) in such a way as to "eliminate risk". This hedge, in turn, implies that the… 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, WebWe derive the Black Scholes European option price formula. We then calculate the derivatives of the option price formula (both call and put) with respect to the Black-Scholes' inputs in order to derive formulae for the Delta, Gamma, Vega, Theta, and Rho. We also give the put call parity for the price and show that all of the Greeks satisfy the parity. changi airport duty free shops
