WebBrownian motion is an important stochastic process that provides a model for option pricing. In particular, we are using a geometric Brownian … Webcorresponding stock and option prices at the time, of interest to the option investor is how these prices can potentially vary over the remaining life of the option. When used to characterize the underlying stock price movements, geometric Brownian motion will allow the potential time paths to be simulated. Such simulation exercises are ...
