This dissertation analysed the performance of Mutual Funds with investments in emerging enterprises until 2004. The analysis was accomplished through comparisons with investments indexes, descriptive statistics, internal return rates and chi-squared statistical test. Factors were identified through qualitative analysis, such as investment strategy and the principal-agent relation, as possible causes of the bad perfomance of these funds. The study also indicated oportunities for the reversion of this scenario and it was based on the anual reports sent by these funds to CVM. The present study concluded that the bad performance of the invested enterprises might be imputed to the lack of more rigid investments criteria by the funds' managers, besides other aspects such as the existence of an agency problem, the Brazilian macroeconomic scenario and, even, imperfections of the local capital markets.
