Gestão de bancos comerciais versus gestão de assets independentes, utilizando modelo CAPM – fundos de ações Brasil

Abstract

This article seeks contribute to a study to identify the best managers of Commercials Banks and Independent Assets of stock mutual Funds ANBIMA Ibovespa Ativotype (FIA). To analyze and differentiate the best managers, the methodology Capital Asset Price Model (CAPM) was used, proposed by William Sharpe (1964) and the Alpha Jensen to capture how the managers generated a return higher than expected by the portfolio's risk level background. Database comprised a panel containing just FIA with monthly quotas of December 2003 to January 2014, with this database and estimated alphas in the individual regressions of 46 funds. After alpha estimating each FIA, these alfa's were arranged in a cross section using a dummy variable for funds managed by Commercial Banks and Independent Assets. From this analysis we can analyze and compare which institutions add more results to investors. For funds managed by Commercial Banks alpha is negative, while the Independent Assets managed by the alpha is statistically positive.
