基于均值-方差混合Lévy运动的价差期权定价的矩匹配方法

Moment Matching Method for Pricing Spread Options with Mean-Variance Mixture Lévy Motions

Dongdong Hu, Hasanjan Sayit, Svetlozar T. Rachev

AI总结:

本研究采用矩匹配方法,推导了带均值-方差混合的指数Lévy模型下价差期权价格的半闭式公式,该公式通过混合分布表示价差价格,经数值测试验证具有准确性,为该类模型下的价差期权定价提供了新的半闭式求解方案。

摘要:

Borovkova等人[4]的论文采用矩匹配方法,推导了对数正态模型下价差期权和一篮子看涨期权价格的闭式公式。在本研究简报中,我们同样采用矩匹配方法,推导了带均值-方差混合的指数Lévy模型下价差期权价格的半闭式公式。Caldana与Fusai[5]的半闭式公式针对一般价格动态,采用傅里叶逆变换表示价差价格,而我们的公式则通过混合分布来表示价差价格。数值测试表明,我们的公式同样能给出准确的价差价格。

英文摘要:

The paper Borovkova et al. [4] uses moment matching method to obtain closed form formulas for spread and basket call option prices under log normal models. In this note, we also use moment matching method to obtain semi-closed form formulas for the price of spread options under exponential Lévy models with mean-variance mixture. Unlike the semi-closed form formulas in Caldana and Fusai [5], where spread prices were expressed by using Fourier inversion formula for general price dynamics, our formula expresses spread prices in terms of the mixing distribution. Numerical tests show that our formulas give accurate spread prices also
