This dissertation analyses the performance of the Brazilian Fixed Income Pension funds, from 2003 to 2014. The sample used in this study corresponds to 382 funds, representing approximately 99 percent of total assets in fixed income pension funds industry. The aim of the study was (i) to analyze the behavior of such category of funds and observe if they have satisfactory performance capacity, (ii) extend this analysis to a segregated group of selected funds by the characteristic of charging fees exemption, named Master Funds (iii) assess whether there are differences in management between brazilian and foreign managers, and (iv) investigate the possibility of creating a benchmark index for the sector in order to facilitate the assessment by the investor during the investment decision. The results indicated, considering Historical Sharpe ratio, that the Fixed Income Pension funds failed to achieve a satisfactory result. However, the Master Fund group achieved a superior performance to the category, also getting an excess return with statistical significance of 5 percent. Regarding the comparison between domestic and foreign managers, we cannot say that there is significant difference between them. The results also found that the relative ratio to CDI is highly relevant, demonstrating its use as a unique benchmark.
