Abstract This paper uses data envelopment analysis (DEA) approach as a nonparametric efficiency tool to preselect efficient assets in large-scale portfolio problems. Thus, we reduce the dimensionality of problems, considering multiple asset performance criteria linear DEA model. We first introduce several reward/risk that are typically used literature identify features financial returns. Second...
