Pricing American Options on Jump-Diffusion Processes Using Fourier Hermite Series Expansions
A Fast Fourier Transform Technique for Pricing American Options Under Stochastic Volatility
This paper develops a non-finite-difference-based method of American option pricing under stochastic volatility by extending the Geske-Johnson compound option scheme. The characteristic function of the underlying state vector is inverted to obtain the vector's density using a kernel-smoothed fast Fourier transform technique. The method produces option values that are closely in line with the values obtained by finite-difference schemes. It also performs well in an empirical application with traded S&P 100 index options. The method is especially well suited to price a set of options with different strikes on the same underlying asset, which is a task often encountered by practitioners.stochastic volatility; heston model; Geske-Johnson scheme; fast fourier transform; characteristic function inversion
