交易成本和模型不确定性下的大规模投资组合配置

Large-Scale Portfolio Allocation Under Transaction Costs and Model Uncertainty

Nikolaus Hautsch, Stefan Voigt

摘要:

本文从理论和实证两个方面研究了有交易成本的投资组合优化问题,并在交易惩罚受交易成本支配的情况下,建立了交易惩罚与协方差收缩之间的联系。我们展示了如何事先纳入交易成本转移到正规化版本的有效配置的最优投资组合。交易成本的监管效果进行了研究,在一个计量经济学的设置,将参数的不确定性和最佳组合的预测分布产生的高频和低频数据。在一个广泛的实证研究中,我们说明了营业额惩罚比常用的收缩方法更有效,是至关重要的,以构建经验表现良好的投资组合。

英文摘要:

We theoretically and empirically study portfolio optimization under transaction costs and establish a link between turnover penalization and covariance shrinkage with the penalization governed by transaction costs. We show how the ex ante incorporation of transaction costs shifts optimal portfolios towards regularized versions of efficient allocations. The regulatory effect of transaction costs is studied in an econometric setting incorporating parameter uncertainty and optimally combining predictive distributions resulting from high-frequency and low-frequency data. In an extensive empirical study, we illustrate that turnover penalization is more effective than commonly employed shrinkage methods and is crucial in order to construct empirically well-performing portfolios.
