Abstract
A novel approach for stress-testing (portfolios of) financial assets is presented. The technique extends the parametric Entropy Pooling approach to skewed and thick-tailed markets. The technique rests on a copula-marginal decomposition for the entropy together with several approximation schemes which renders the numerical computations feasible for real-life problems. An illustration with a portfolio of European options is presented.
