Brownian motion model

The Brownian motion models for financial markets are based on the work of Robert C. Merton and Paul A. Samuelson, as extensions to the one-period market models of Harold Markowitz and William F. Sharpe, and are concerned with defining the concepts of financial assets and markets, portfolios, gains and wealth in terms of continuous-time stochastic processes. Under this model, these assets have continuous prices evolving continuously in time and are dri… WebJun 25, 2024 · Random Walk. Besides using the discrete or continuous model of Brownian Motion, we can also use another technique called random walk. Random walk is derived from a series of rescaled Bernoulli Random Variables, we can use them to stimulate a Brownian Motion. Random Walk is basically the standpoint for pricing models such as …
