I spent a couple of days with the code I attached, but I can't really help, what's wrong, it's not creating a random process which looks like standard brownian motions with drift. My parameters like mu and sigma (expected return or drift and volatility) tend to change nothing but the slope of the noise process.

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.

Fractional Brownian Motion in Finance Bernt Øksendal1),2) Revised June 24, 2004 1) Center of Mathematics for Applications (CMA) Department of Mathematics, University of Oslo P.O. Box 1053 Blindern, N–0316, Oslo, Norway and 2) Norwegian School of Economics and Business Administration, Helleveien 30, N–5045, Bergen, Norway Abstract The best way to explain geometric Brownian motion is by giving an example where the model itself is required. Consider a portfolio consisting of an option and an offsetting position in the underlying asset relative to the option’s delta. Computational Finance At the moment of pricing options, the indisputable benchmark is the Black Scholes Merton (BSM) model presented in 1973 at the Journal of Political Economy. In the paper, they derive a mathematical formula to price options based on a stock that follows a Geometric Brownian Motion.

Brownian motion refers to either the physical phenomenon that minute particles immersed in a ﬂuid move around randomly or the mathemat-ical models used to describe those random movements [11], which will be explored in this paper. History: Brownian motion was discovered by the biologist Robert Brown [2] in 1827.

2013-06-04 · Brownian motion is a simple continuous stochastic process that is widely used in physics and finance for modeling random behavior that evolves over time. Examples of such behavior are the random movements of a molecule of gas or fluctuations in an asset’s price. Brownian motions have unbound variation. This means that if the sign of all negative gradients were switched to positive, then $B$ would hit infinity in an arbitrarily short time period. Brownian motions are continuous.

Brownian motion- the incessant motion of small particles suspended in a fluid- is an important topic in statistical physics and physical chemistry. This book

There are other reasons too why BM is not appropriate for modeling stock prices. Instead, we introduce here a non-negative variation of BM called geometric Brownian motion, S(t), which is deﬁned by S(t) = S 0eX(t), (1) Brownian motions have unbound variation. This means that if the sign of all negative gradients were switched to positive, then $B$ would hit infinity in an arbitrarily short time period. Brownian motions are continuous.
