Background: We have reason to believe that in fear of doing wrong; most PPM investors are crippled to stay passive. Hence, they are not using the full potential of the PPM systems. Some are lured in to use professional pension saving steward by promises of abnormal return. According to efficient market hypothesis this would be impossible, however, studies have shown that their might exist inherent financial anomalies that by the utilization of historic information can open the window for abnormal return.
Purpose: The purpose of the study is to draw attention to the problem of using ex ante data to predict ex post returns. Thus, we would have evaluated the practical implication of using ex ante data as a determinant in relation to optimal PPM funds selection, and if possible to provide some simplistic guidelines for the average PPM investor.
Results: We found a handful of portfolios that gave significant results against their own index; however, when tested against Sverige, rena and Global, Mix bolag the evidence of abnormal return were thin. From our results, we conclude that their seems to be a persistence effect, as top achievers continued to perform above average in almost all cases, however, one could not profitize on abnormal return other than by chance. Consequently, historic return can give the investor an aid in optimal portfolio selection. Historic figures concerning standard deviation, expense ratios, and load fees all significantly correlated with return, however, neither seem to give the investor an edge in optimal PPM portfolio selection.
