T. Rockafellar and S. Uryasev, 2000). Moreover, the fact that the CVaR function is convex, and its minimization model can be condensed into a simple linear programming formula, make it a widely used and studied area of research and development. On the other optimization using Conditional Value at Risk (CVaR) which is defined as expected value of losses exceeding VaR. Their optimization model minimizes CVaR while calculating VaR and in the case of normally distributed portfolio returns; the minimum-CVaR portfolio is equivalent to the minimum-VaR portfolio. In particular, when c = cd *, min, the portfolio is just the mean-CVaR portfolio, and when c = cd *, max, the portfolio is the mean-variance portfolio. We can see that a larger c * leads to a more diversified portfolio, which has a smaller variance but larger CVaR (c *). These findings are in line with that in Roman et al.

The rst constraint ensures minimal expected return r 0, x i are (nonnegative) portfolio weights which sum to one. 4 / 6. If the distribution of R i is discrete with realizations r … Ruszczynski (2002) for an overview of CVaR. In addition, minimizing CVaR typi-cally leads to a portfolio with a small VaR. A convex optimization problem has been proposed in Rockafellar and Uryasev (2000) to compute the optimal CVaR portfolio.

If Xis a constraint that the portfolio must satisfy, the following lemma holds for the formulation of a portfolio optimization problem using CVaR as the risk measure. Lemma 3.2. In this chapter we formulate and solve the mean-CVaR portfolio model, where covariance risk is now replaced by the conditional Value at Risk as the risk measure. In contrast to the mean-variance portfolio optimization problem, we no longer assume the restriction consisting in the set of assets to have a multivariate elliptically contoured distribution.
