Viés de sobrevivência nos fundos de investimento de renda variável no Brasil

Resumo

The goal of this paper is to analyze the effects of the asset managers strategy of eliminating the funds with poor performance in order to preserve the best performance as possible of the remain funds. This practice leads to overestimating the return of a group of funds, generating a difference between the unbiased and the biased portfolio that is called survivorship bias. This study is focused on Brazilian equities funds. The total number of funds within the sample is 1.106, including liquidated, incorporate and active funds. The performance of funds was analyzed from June 2004 through June 2012. Regressions were realized by the Least Square method. For the equal weighted portfolios, the results signalized a positive bias for the end of period survivors (roughly 0,10% per month). The opposite was obtained to the full period survivors, indicating theirs worst performance compared to the unbiased portfolio. For the value weighted portfolios, despite being statistically significant, the bias is small (0,03% per month) with the end of period funds. The full period survivors, when compared with the unbiased portfolio, showed an insignificant result.
