Financial modeling is conventionally based on a Brownian motion (Bm). A Bm is a semimartingale process with independent and stationary increments. However, some financial data do not support this Brownian motion Brownian Motion is a continuous Stochastic process named in honor of Norbert Wiener.

2 Stochastic process. A mathematical process that appears to fluctuate randomly over time. 3 Trend-following behavior Brownian Motion, Martingales, and Stochastic Calculus provides a strong theoretical background to the reader interested in such developments. Beginning graduate or advanced undergraduate students will benefit from this detailed approach to an essential area of probability theory. Brownian motion in the context of the young science of statistical mechanics. Statistical mechanics aims to understand the thermal behavior of macroscopic matter in terms of the average behavior of microscopic constituents under the in uence of mechanical forces. 7.

This paper provides in this way an endogenous justification for the ap-pearance of Brownian Motion in Finance theory. 1 Introduction Since the pioneer work of Bachelier [2], finance theory often uses a Brownian Motion to model the evolution of the price system on the stock markets.

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) The Brownian Motion in Finance: An Epistemological Puzzle . 1 3. 1970, p.

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. Brownian motion is used in finance to model short-term asset price fluctuation.
