In this paper we propose a model for mean-variance portfolio selection in form of a non-linear mixed integer programming problem. We take into account the transaction costs, taxes and limited divisibility of the stocks. For finding the optimal solution, the combination of sub-gradient methods and branch and bound ones is used.
