价差期权定价的傅里叶变换方法

A Fourier transform method for spread option pricing

T. R. Hurd, Zhuowei Zhou

摘要:

价差期权是一种以多种资产为基础的衍生合约,广泛应用于各种金融市场。计算这种乘积的近似方法有很长的历史,但迄今为止还没有一种精确、有效和足够灵活的首选方法适用于一般模型。本文基于价差期权支付函数的傅里叶分析,给出了一般价差期权定价的新公式。我们的详细调查证明了快速傅立叶变换实现这个公式的价格计算的有效性。结果表明,该方法易于实现、稳定、高效,适用于各种资产定价模型。

英文摘要:

Spread options are a fundamental class of derivative contract written on multiple assets, and are widely used in a range of financial markets. There is a long history of approximation methods for computing such products, but as yet there is no preferred approach that is accurate, efficient and flexible enough to apply in general models. The present paper introduces a new formula for general spread option pricing based on Fourier analysis of the spread option payoff function. Our detailed investigation proves the effectiveness of a fast Fourier transform implementation of this formula for the computation of prices. It is found to be easy to implement, stable, efficient and applicable in a wide variety of asset pricing models.
