Do Spanish mutual fund managers use public and private information correctly? Use of information in mutual fund management

In this work, we evaluate the use of public and private information by Spanish fund managers by means of an analysis of their traditional and conditional performance. Furthermore, we repeat this analysis for various fund subsets compiling their different characteristics, which allows us to determine the impact of diverse effects on performance. In addition, we restrict this analysis to the fund subset for which public information variables show a high predictive power. Prior to the model application, we develop an analysis of the integration order of variables and of multi-collinearity to assure models work well.
