Robustness and bootstrap approaches to SSD portfolio efficiency testing
نویسنده
چکیده
This paper deals with portfolio efficiency testing with respect to second-order stochastic dominance (SSD) criteria. Unlike the pair-wise tests the portfolio efficiency tests allow for full diversification across the assets. As usual in SSD testing, the returns of assets are modeled by scenarios. We apply a computationally attractive method to test whether a US market portfolio, proxied by CRSP all share index, is SSD efficient with respect to 48 US industry representative portfolios. Moreover, we present a robust version of SSD portfolio efficiency test that allows for small errors in data and we analyze their impact on the market portfolio SSD efficiency. We enrich the results by the estimation of p-value of market portfolio SSD efficiency when the bootstrap technique to the data is applied.

Testing for Stochastic Dominance Efficiency
We consider consistent tests for stochastic dominance efficiency at any order of a given portfolio with respect to all possible portfolios constructed from a set of assets. We propose and justify approaches based on simulation and the block bootstrap to achieve valid inference in a time series setting. The test statistics and the estimators are computed using linear and mixed integer programmin...
متن کاملRobustness-based portfolio optimization under epistemic uncertainty
In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...
متن کاملMeasuring of second-order stochastic dominance portfolio efficiency
In this paper, we deal with second-order stochastic dominance (SSD) portfolio efficiency with respect to all portfolios that can be created from a considered set of assets. Assuming scenario approach for distribution of returns several SSD portfolio efficiency tests were proposed. We introduce a δ-SSD portfolio efficiency approach and we analyze the stability of SSD portfolio efficiency and δ-S...
متن کاملRobustness in portfolio optimization based on minimax regret approach
Portfolio optimization is one of the most important issues for effective and economic investment. There is plenty of research in the literature addressing this issue. Most of these pieces of research attempt to make the Markowitz’s primary portfolio selection model more realistic or seek to solve the model for obtaining fairly optimum portfolios. An efficient frontier in the ...
متن کاملStatistical Inference on Stochastic Dominance Efficiency. Do Omitted Risk Factors Explain the Size and Book-to- Market Effects?
This paper discusses statistical inference on the second-order stochastic dominance (SSD) efficiency of a given portfolio relative to all portfolios formed from a set of assets. We derive the asymptotic sampling distribution of the Post test statistic for SSD efficiency. Unfortunately, a test procedure based on this distribution involves low power in small samples. Bootstrapping is a more power...
