Using the Fama-French Three factor model and the Fama-French Five factor model, this study aims to analyze the factors that can affect the performance of stock mutual funds in Indonesia during the period January 2016 to June 2021. The factors observed include market factor, size factor, value factor, profitability factor, and investment factor. This study also aims to compare the measurement results between the use of the Three factor model and the Five-Factor in explaining the excess return of stock mutual funds. This study uses a quantitative approach with the Robust Least Square method using daily data, analyzed quarterly for every year. The sample includes 109 actively managed equity mutual funds during the observation period. The results show that the market factor is the only factor that found significantly can affect the excess return of equity mutual funds in Indonesia. Based on the Adjusted R2 value, the Fama-French Five factor model shows a greater value than the Three factor model, but no significant difference was found between the two models in explaining the performance of equity mutual funds in Indonesia.
