Abstract: This paper provides explicit expression for the lower bound and the upper bound of the overall VaR of a portfolio of business units when the joint risks factors of each business unit follows a mixture of multivariate elliptic distributions with dynamic conditional correlation matrix. We use copula to measure the dependence between the profits and losses (P&Ls) of different business units in the portfolio.
