Revealing the implied risk-neutral MGF from options: The wavelet method

摘要

Options are believed to contain unique information on the risk-neutral moment generating function(MGF) or the risk-neutral probability density function(PDF) of the underlying asset. This paper applies the wavelet method to approximate the implied risk-neutral MGF from option prices. Monte Carlo simulations are carried out to show how therisk-neutralMGFcanbeobtainedusingthewaveletmethod.Withthe Black–Scholes model as the benchmark, we offer anovel method to reveal the implied MGF,and to price in-sample options and forecast out-of-sample option prices with the estimated MGF.
