This article considers a multi-asset model based on Wishart processes that accounts for stochastic volatility and for stochastic correlations between the underlying assets, as well as between their volatilities. The model accounts for the existence of correlation term structure and correlation...

This article postulates a flexible specification for the implied volatility surface, which accounts for the existence of volatility skew and term structure. I show that it is possible to express the local volatility function in terms of the implied volatility. I then obtain an analytic formula...

European quanto derivatives are usually priced using the well known quanto adjustment corresponding to the forward of the quantoed asset under the assumptions of the Black-Scholes model. In this article, I present the quanto adjustment corresponding to the local volatility model that allows...

Multi-asset options exhibit sensitivity to the correlations between the underlying assets and these correlations are notoriously unstable. Moreover, some of these options such as the digital outperformance options, have a cross-gamma that changes sign depending on the relative evolution of the...
