摘要
基于分形市场假说,提出了分形CEV模型,扩展了传统的CEV模型,并导出了服从该模型的期权定价方程。同时,为了克服定价方程难以求出解析解的困难,提供了一种采用差分思想的蒙特卡罗模拟方法。
By using fractional Brownian motion to replace geometric Brownian motion, the efficient market hypothesis is generalized hypothesis. provided to as fractal market hypothesis. A fractal CEV model is proposed, which is based on the fractal market Meanwhile, the optional pricing formula obeying the fractal CEV model is derived. Monte Carlo simulation is overcome the difficulty to get analytical solutions of the optional pricing equation.
