A geometric Brownian motion (GBM) (also known as exponential Brownian motion) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion (also called a Wiener process) with drift. It is an important example of stochastic processes satisfying … Visa mer A stochastic process St is said to follow a GBM if it satisfies the following stochastic differential equation (SDE): $${\displaystyle dS_{t}=\mu S_{t}\,dt+\sigma S_{t}\,dW_{t}}$$ where Visa mer GBM can be extended to the case where there are multiple correlated price paths. Each price path follows the underlying process Visa mer In an attempt to make GBM more realistic as a model for stock prices, one can drop the assumption that the volatility ($${\displaystyle \sigma }$$) is constant.
