| Tiivistelmä: | Black and Scholes explained the pricing of derivative securities by deriving the price of a call option when the underlying stock satisfies the geometric Brownian motion. However, different researchers have proven that the Brownian assumption is not acceptable. We need a pricing model with changing variance. Section II presents a stochastic variance model, and Section III solves it by a Monte Carlo method. |
