欧式期权价格的奇异Fourier-Padé级数展开

Singular Fourier-Padé Series Expansion of European Option Prices

Tat Lung Chan

摘要:

我们应用一种新的数值方法,奇异傅里叶-帕德(SFP)方法发明的Drivel和Fornberg(2001,2011),定价欧式期权的Lévy和仿射过程。这种应用背后的动机是为了减少当前傅立叶技术的效率低下,当它们被用来近似分段连续(非光滑)的概率密度函数。当快速傅立叶变换和傅立叶级数等技术应用于具有非光滑概率密度函数的期权定价和套期保值时,它们会引起吉布斯现象,因此,对于具有跳跃值或导数的密度函数,这些技术收敛缓慢。这严重地不利地影响了这些技术的效率和准确性。在本文中,我们推导出定价公式和选项希腊使用SFP方法解决吉布斯现象,恢复全局谱收敛速度。此外,我们表明,我们的方法需要少量的条款,以产生快速的误差收敛,它能够准确地定价任何欧式期权深/出的钱,非常长/短的期限。此外,我们进行误差界分析的SFP方法在期权定价。数值实验表明,与现有方法相比,该方法具有较好的性能。

英文摘要:

We apply a new numerical method, the singular Fourier-Padé (SFP) method invented by Driscoll and Fornberg (2001, 2011), to price European-type options in Lévy and affine processes. The motivation behind this application is to reduce the inefficiency of current Fourier techniques when they are used to approximate piecewise continuous (non-smooth) probability density functions. When techniques such as fast Fourier transforms and Fourier series are applied to price and hedge options with non-smooth probability density functions, they cause the Gibbs phenomenon, accordingly, the techniques converge slowly for density functions with jumps in value or derivatives. This seriously adversely affects the efficiency and accuracy of these techniques. In this paper, we derive pricing formulae and their option Greeks using the SFP method to resolve the Gibbs phenomenon and restore the global spectral convergence rate. Moreover, we show that our method requires a small number of terms to yield fast error convergence, and it is able to accurately price any European-type option deep in/out of the money and with very long/short maturities. Furthermore, we conduct an error-bound analysis of the SFP method in option pricing. This new method performs favourably in numerical experiments compared with existing techniques.
