In this work, by utilizing the stock price data, we examine the correctness of the existing Geometric Brownian Motion model under standard statistical tests. Then we demonstrate the development of the modified linear models under different data partitionings, with or without jumps. Empirical ...
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...
Creates and displays a geometric Brownian motion model (GBM), which derives from the cev (constant elasticity of variance) class.
It converges to GBM or exponential Brownian motion (EBM) when the time step (Δt) tends to zero. The essence of the Cox model has three basic components or equations: 1. Up option value: u=eσΔt 2. Down option value: d=1u=e−σΔt 3. Risk neutral transitional probability: p=...

Our findings demonstrate that while the Geometric Brownian Motion model effectively captures general market trends, the Multifractional Brownian Motion model reflects the nuanced volatilities and structural shifts in green energy markets, particularly during heightened geopolitical tension. The Hurst analysis ...
On condition that price process isgeometric Brownian motion,a multi-objective programming model for the portfolio investment is established by minimizing the risk and maximizing the return. 在证券的价格过程是几何布朗运动的前提下,建立了最优投资组合的多目标规划模型,使得投资收益最大和投资风险最小,并利用...
