dc.description.abstractThe discussion on the efficiency of markets is recurring in the studies of finance. This study takes up the theme, to investigate whether it is possible for the investor to follow the recommendations of public investments to market gains. Compared to previous studies, this research adds a new variable, the incidence of income tax – I.R. as an important transaction cost. The current study works with a portfolio with active administration formed from the indications of analysts consulted by the Valor Econômico newspaper between January 2003 and December 2011. Make up the sample, as instruments of control, the Ibovespa index and three investment funds with active management and ballast in the Ibovespa index. Various statistics were calculated, in order to demonstrate the performance of the portfolios. Statistical tests were conducted to evaluate the statistical significance of differences (ANOVA and Tukey Test). The results, it appears that, the active management portfolio, CV, presented not only returns higher than those established for other portfolios, like a performance in terms of risk/return also. However, statistically, only one performance measure proved to be significant. This does not allow State categorical way the superiority of the active administration. Although most of the results were not statistically significant, it can be said that the investor would not be insensitive to differences found, because it was possible to observe the following aspects: getting wallet with superior results to the Sharpe Index, Jensen alpha, the Treynor index and index M2. This all allows you to put in doubt the efficiency of the Brazilian capital market.en
