Black scholes ito lemma
WebGeometric Brownian motion is used to model stock prices in the Black–Scholes model and is the most widely used model of stock price behavior. Some of the arguments for using GBM to model stock prices are: The expected returns of GBM are independent of the value of the process (stock price), which agrees with what we would expect in reality.
