Most of the time some strong assumptions are made to simplify the estimation process and there has to be a trade-off between ease of estimate and accuracy. In this paper we develop a copula-based approach in order to estimate the Value-at-Risk of portfolios containing financial assets. We propose a survival copula that could solve many difficulties that risk managers currently have to face. We compare the results it provides to those of more classic copulas, on portfolios composed of two and three indices between 1991 and 2005, so that our study covers various market trends. The Heavy Right Tail copula we propose fulfills the various backtest constraints required by regulators.
