In this paper, we propose a general framework for the valuation of options in stochas-tic local volatility (SLV) models … as special cases. Standard stochastic volatility models, such as Heston, Hull-White, Scott, Stein-Stein, α …-Hypergeometric, 3/2, 4/2, mean-reverting, and Jacobi stochastic volatility models, also fall within this general framework. We propose a …

The first part of this document is dedicated to the pricing of undiscounted Vanilla Options: we compute the price and sensitivities of Calls and Puts, and highlight the different FX Delta conventions. The most important application of specific FX market conventions (and particularly Deltas...

We apply the Malliavin calculus to the stochastic string framework and obtain a Clark-Ocone-like formula. This result allows us to rewrite the hedging portfolio explicitly in terms of the Malliavin derivative of the discounted payoff. We illustrate this new result with two applications. Firstly,...

We achieve this by using the maturity randomization method known as … Canadization. The volatility process is characterized by fast and slow scale fluctuating factors.
