金融行业投资组合构建的随机可达性方法

A stochastic reachability approach to portfolio construction in finance industry

Giordano Pola, Gianni Pola

摘要:

在金融业中,投资组合构建涉及如何将投资者的财富分配到一个资产类别的菜单上,以使投资者的收益最大化。目前使用的主要方法是基于经典Markowitz模型的变化。然而,世界市场的最新发展显示了这种方法的局限性,并促使许多研究人员和从业人员研究投资组合构建的替代方法。在本文中,我们提出了一种方法来最优投资组合的建设最近的结果的基础上随机可达性,克服了目前的方法的一些限制。给定投资者希望其投资组合保持在其中的一系列目标集,合成最优投资组合分配,以最大化投资组合价值满足目标集要求的联合概率。在美国市场的案例研究,这表明所提出的方法在投资组合建设的好处。包括与传统方法的比较。

英文摘要:

In finance industry portfolio construction deals with how to divide the investors' wealth across an asset-classes' menu in order to maximize the investors' gain. Main approaches in use at the present are based on variations of the classical Markowitz model. However, recent evolutions of the world market showed limitations of this method and motivated many researchers and practitioners to study alternative methodologies to portfolio construction. In this paper we propose one approach to optimal portfolio construction based on recent results on stochastic reachability, which overcome some of the limits of current approaches. Given a sequence of target sets that the investors would like their portfolio to stay within, the optimal portfolio allocation is synthesized in order to maximize the joint probability for the portfolio value to fulfill the target sets requirements. A case study in the US market is given which shows benefits from the proposed methodology in portfolio construction. A comparison with traditional approaches is included.
