| Research Abstract |
In this project, we investigate a portfolio optimization approach on the basis of the minimizations of VaR and CVaR, which have obtained a growing popularity both in practice and theory. Employing a theoretical underpinning known as the generalization theory for the ν-SVM, a statistical learning method, we empirically show that the norm-constrained versions of VaR and CVaR minimizations achieve better out-of-sample performance than the unconstrained versions.
