本文考虑了摩擦市场下的多期证券投资组合选择问题,利用极小极大原理,建立了在含有机会成本和交易成本的多期极小极大投资组合选择模型.利用非线性规划相关理论,证明了该模型最优解的存在性,并利用凸规划相关理论与Kuhn—Tucker条件给出了求解该模型的一种方法,最后通过实例对结论进行了说明.
This paper deals with a multi-period portfolio selection problem in the frictional market: A multi-period minimax portfolio selection model with opportunity costs and transaction costs is proposed. By using the theory of nonlinear programming, we prove the existence of optimal solution of this model. Moreover, the method for solving this model is given by using the theory of convex programming and Kuhn-Tucker condition. Finally, a numerical example is given to illustrate our results.
