1 Geometric Brownian Motion Model in Financial Market Zhijun Yang 2 Before we start our computer simulation, let explore more mathematical aspects of the geometric brow- nian motion. First note that given drift rate and volatility rate, we can represent GBM solution in the form S(t) = S 0 ...

Geometric Brownian Motion The usual model for the time-evolution of an asset priceS(t)is given by the geometric Brownian motion, represented by the followingstochastic differential equation: dS(t)=μS(t)dt+σS(t)dB(t) Note that the coefficientsμandσ, representing thedriftandvolatilityof the...

The geometric Brownian motion (GBM) has long served as a foundational model for capturing stochastic nature of systems characterized by the continuous random fluctuations. In particular, this model has been argued to be well suited for forecasting diffusion processes1, population dynamics2 or most not...
3.1.1 Geometric Brownian Motion Model Brownian motion, first discussed by Brown in 1827 in the context of motion of pollens, further explained by Einstein in 1905, and formulated by Wiener in 1918 has strong ties with the modeling of stock prices. Bachelier in 1900 described the price variatio...
Joint Laplace transform of the geometric Brownian motion with affine drift and its time-integral An alternative form of the GBM with affine drift to (4.1) is given bydXt=(rXt−δ)dt+σXtdBt,X0=x0>0.Since such a model typically arises in the context of option pricing in finance literat...
