Spectral Decomposition of Option Prices in Fast Mean-Reverting Stochastic Volatility Models
Using spectral decomposition techniques and singular perturbation theory, we develop a systematic method to approximate the prices of a variety of options in a fast mean-reverting stochastic volatility setting. Four examples are provided in order to demonstrate the versatility of our method. These include: European options, up-and-out options, double-barrier knock-out options, and options which pay a rebate upon hitting a boundary. For European options, our method is shown to produce option price approximations which are equivalent to those developed in .  Jean-Pierre Fouque, George Papanicolaou, and Sircar Ronnie.
