英文摘要:
  We derive properties of the cdf of random variables defined as saddle-type points of real valued continuous stochastic processes. This facilitates the derivation of the first-order asymptotic properties of tests for stochastic spanning given some stochastic dominance relation. We define the concept of Markowitz stochastic dominance spanning, and develop an analytical representation of the spanning property. We construct a non-parametric test for spanning based on subsampling, and derive its asymptotic exactness and consistency. The spanning methodology determines whether introducing new securities or relaxing investment constraints improves the investment opportunity set of investors driven by Markowitz stochastic dominance. In an application to standard data sets of historical stock market returns, we reject market portfolio Markowitz efficiency as well as two-fund separation. Hence, we find evidence that equity management through base assets can outperform the market, for investors with Markowitz type preferences.

中文摘要:
我们推导了定义为实值连续随机过程鞍型点的随机变量的cdf的性质。这有助于在给定一些随机优势关系的情况下推导随机生成检验的一阶渐近性质。我们定义了Markowitz随机优势跨越的概念,并给出了跨越性质的解析表示。我们构造了一个基于子抽样的非参数跨越检验,并推导了它的渐近精确性和一致性。跨越法决定了引入新证券或放松投资约束是否会改善马科维茨随机优势驱动的投资者的投资机会集。在对历史股票市场收益率标准数据集的应用中,我们拒绝了市场投资组合马科维茨效率以及两个基金分离。因此,我们发现有证据表明,对于马科维茨型偏好的投资者来说,通过基础资产进行的股权管理可以跑赢市场。
