Value at risk (VaR) has become a standard measure of portfolio risk over the last decade. It even became one of the … corner stones in the Basel II accord about banks' equity requirements. Nevertheless, the practical application of the VaR … concept suffers from two problems: how to estimate VaR and how to optimize a portfolio for a given level of VaR? For the first …

This paper proposes a method for estimating the VaR of a portfolio based on copula and extreme value theory. Each …

This paper examines different multivariate models to evaluate what are the main determinants when doing VaR forecasts … and the time sample used for VaR backtesting. The calculated VaR values are then compared using three different testing …
