Webb8 dec. 2024 · Brownian motion is furthermore Markovian and a martingale which represent key properties in finance. Brownian motion was first introduced by Bachelier in 1900. Samuelson then used the exponential of a Brownian motion (geometric Brownian motion) to avoid negativity for a stock price model. WebbEquation 70— Solution to the Geometric Brownian Motion SDE for Stock Prices. This model in finance is also known as the log-normal asset return model, as we are using logarithmic prices.
