We propose a consistent and computationally efficient 2-step methodology for the estimation of multidimensional non-Gaussian asset models built using Lévy processes. The proposed framework allows for dependence between assets and different tail-behaviors and jump structures for each asset. Our...

In this work we perform a pricing exercise of different types of spread options; we particularly focus on European calendar and crack spread options. We present the expressions followed by the joint characteristic functions of the underlying log-prices for a panel of bivariate processes. The...

In this note we prove a simple formula to compute the Incremental Volatility, i.e. the change in the portfolio volatility due to the removal of one asset from the portfolio. The common practice adopted in the literature and in the industry is to avoid the full recalculation of the portfolio...
