� Geometric Brownian motion is used to model stock prices in the Black–Scholes model and is the most widely used model of stock price behavior. Geometric Brownian motion is a mathematical model for predicting the future price of stock. S t is the stock price at time t, dt is the time step, μ is the drift, σ is the volatility, W t is a Weiner process, and ε is a normal distribution with a mean of zero and standard deviation of one . GBM assumes that a constant drift is accompanied by random shocks. x�)F

This is known as Geometric Brownian Motion, and is commonly model to define stock price paths. Geometric Brownian motion is a mathematical model for predicting the future price of stock. On stock price prediction using geometric Brownian Motion model, the algorithm starts from calculating the value of return, followed by estimating value of volatility and drift, obtain the stock price forecast, calculating the forecast MAPE, calculating the stock expected price and calculating the confidence level of 95%. ing the direction of stock price and accurate stock price level. It can be constructed from a simple symmetric random walk by properly scaling the value of the walk. You will only need to do this once.
