Midiendo la eficiencia financiera en el manejo de los portafolios de inversión de las AFP en el Perú: un enfoque robusto

Abstract

This document assess whether the investment portfolio of the pension plan funds administrators (AFP) were financially efficient in the period 2006-2011. An investment portfolio would be financially more efficient when the difference between its own ratio Sharpe and the market portfolio ones is the least possible. The estimation of this document is performed under the nonparametric Shrinkage approach, a robust optimization portfolio method. It considers relevant legal restrictions, as well as, restrictions that capture the illiquidity of the local capital market. The main conclusion drawn is that financial efficiency did not exist in any of the three kinds of funds managed in the analysis period.
