Brownian Motion in the Stock Market It is shown that common-stock prices, and the value of money can be regarded as an ensemble of decisions in statistical equilibrium, with properties quite analogous to an ensemble of particles in statistical mechanics. If Y=log e[P(t+τ)......

The process has been used beneficially in such areas as statistical testing of goodness of fit, analyzing the price levels on the stock market, and quantum mechanics. When σ = 1, the process is called standard Brownian motion. The interpretation of Brownian motion as the limit of the random...
As a matter of convenience, stock simulation models such as the Brownian motion often assume that a stock's rate of return follows a normal distribution. However, stock market bubbles and crashes occur too often throughout history that they would have otherwise been deemed highly improbable by a...
Beyond physics, there has been a large impact, with economists realizing that fluctuations in the stock market followed similar rules. Modern chaos theory, trying to understand the processes behind seemingly random fluctuations, has its roots in Brownian motion. ...
Brownian motion, the tiny random movements of small objects suspended in a fluid, has served as a paradigm for concepts of randomness ranging from noise in light detectors to fluctuations in the stock market. Using digital video microscopy, the researchers directly observed the twisty "random walks...

In Example 14.45, we constructed a (canonical) process (Xt )t∈[0,∞) with independent stationary normally distributed increments. For example, such a process can be used to describe the motion of a particle immersed in water or the change of prices in the stock market. We are now interes...
In this paper, we consider the drawdown and drawup of the fractional Brownian motion with trend, which corresponds to the logarithm of geometric fractional Brownian motion representing the stock price in financial market. We derive the asymptotics of tail probabilities of the maximum drawdown and max...
