Aggregate Brazilian Mutual Fund Stockholdings and Asset Returns

Advisor: Ruy Monteiro Ribeiro

This study aims to investigate whether there is a relationship between aggregate Brazilian mutual fund positions and past, concurrent, and future stock performance. Using monthly fund portfolio data for 30.416 funds between 2006 and 2018 and market data for 84 stocks, several panel data regressions were ran to test the correlation between stock total returns and both the level and change in mutual fund aggregate long and short positions. In addition, the data was used in testing a long-short investing strategy in which stocks with high fund ownership indicators are purchased and stocks with low fund ownership indicators are sold.
