Pricing early-exercise and discrete barrier options by fourier-cosine series expansions

A Novel Pricing Method for European Options Based on Fourier-Cosine Series Expansions

Abstract. Here we develop an option pricing method for European options based on the Fourier-cosine series, and call it the COS method. The key insight is in the close relation of the characteristic function with the series coefficients of the Fourier-cosine expansion of the density function. In most cases, the convergence rate of the COS method is exponential and the computational complexity i...

Pricing early-exercise and discrete barrier options by Shannon wavelet expansions

We present a pricing method based on Shannon wavelet expansions for early-exercise and discretely-monitored barrier options under exponential Lévy asset dynamics. Shannon wavelets are smooth, and thus approximate the densities that occur in finance well, resulting in exponential convergence. Application of the Fast Fourier Transform yields an efficient implementation and since wavelets give loc...

Efficient Pricing of Early–Exercise and Exotic Options Based on Fourier Cosine Expansions

DELFT UNIVERSITY OF TECHNOLOGY REPORT 08-02 On an Option Pricing Method based on Fourier-Cosine Series Expansions

Here we develop an option pricing method for European options based on the Fourier-cosine series, and call it the COS method. The convergence rate of the COS method is exponential and the computational complexity is linear. It has a wide range of applicability for different underlying dynamics, including Lévy processes and Heston’s stochastic volatility model, and for various types of option co...

DELFT UNIVERSITY OF TECHNOLOGY REPORT 10-03 Acceleration of Option Pricing Technique on Graphics Processing Units

The acceleration of an option pricing technique based on Fourier cosine expansions on the Graphics Processing Unit (GPU) is reported. European options, in particular with multiple strikes, and Bermudan options will be discussed. The influence of the number of terms in the Fourier cosine series expansion, the number of strikes, as well as the number of exercise dates for Bermudan options, are ex...
