局部波动率跳跃扩散模型下篮子期权定价的渐近展开法

Basket Options Valuation for a Local Volatility Jump-Diffusion Model with the Asymptotic Expansion Method

Guoping Xu, Harry Zheng

摘要:

本文讨论了一类跳跃扩散模型的一篮子期权定价问题。标的资产价格遵循一些相关的局部波动扩散过程与系统的跳跃。本文导出了一般随机过程的正向偏积分微分方程(PIDE),并利用渐近展开方法逼近了篮子值过程随机方差的条件期望。数值试验表明,在大多数情况下,与蒙特卡罗等方法相比,该方法具有快速、准确的特点。

英文摘要:

In this paper we discuss the basket options valuation for a jump-diffusion model. The underlying asset prices follow some correlated local volatility diffusion processes with systematic jumps. We derive a forward partial integral differential equation (PIDE) for general stochastic processes and use the asymptotic expansion method to approximate the conditional expectation of the stochastic variance associated with the basket value process. The numerical tests show that the suggested method is fast and accurate in comparison with the Monte Carlo and other methods in most cases.
