摘要：
In this paper, we study extensions of the classical Markowitz' mean-variance portfolio optimization model, and VaR is used as risk measure. As is well known, VaR is not sub-additive. This problem will be partially solved by introducing a new variable "diversification" besides income and VaR in our modified model. Empirical tests on Shanghai Stock 50 Index show that the new model promotes diversification.
