英文摘要:
We introduce a solution scheme for portfolio optimization problems with cardinality constraints. Typical portfolio optimization problems are extensions of the classical Markowitz mean-variance portfolio optimization model. We solve such type of problems using a method similar to column generation. In this scheme, the original problem is restricted to a subset of the assets resulting in a master convex quadratic problem. Then the dual information of the master problem is used in a sub-problem to propose more assets to consider. We also consider other extensions to the Markowitz model to diversify the portfolio selection within the given intervals for active weights.

中文摘要:
我们介绍了一种带基数约束的投资组合优化问题的解决方案。典型的投资组合优化问题是经典Markowitz均值-方差投资组合优化模型的扩展。我们使用类似于列生成的方法来解决此类问题。在该方案中,原始问题被限制为资产的子集,从而产生一个主凸二次问题。然后将主问题的对偶信息用于子问题,以提出更多需要考虑的资产。我们还考虑了对Markowitz模型的其他扩展,以在给定的主动权重区间内使投资组合选择多样化。
