CONSTRUCTION AND INFERENCES OF THE EFFICIENT FRONTIER IN ELLIPTICAL MODELS

In this paper, we construct a confidence region for the efficient frontier assuming the asset returns to be matrix elliptically contoured distributed. Our results extend the findings of Bodnar and Schmid (2009) to the non-normal distributed asset returns. In order to correct the overoptimism of the sample efficient frontier documented in Siegel and Woodgate (2007), the unbiased estimator of the efficient frontier is suggested. Moreover, we derive an exact overall F -test for the efficient frontier in elliptical models.
