Mutual funds are important investment instruments for domestic investors, so how to evaluate the performance of the portfolio of mutual funds would be a worthwhile topic to investigate. This paper employs five different rules for selecting the portfolio of mutual funds superior to the market index, and the factors of affecting the performance of mutual funds portfolios are examined as well. In this empirical study, we find the performance of mutual funds selected by 4433 rule, 54321 rule, and rule with concerning beta and sharpe index will outperform than the market index. In addition, we also find that the scale of a mutual fund and the number selected as superior mutual fund has positive effect to the performance of the mutual fund; however, the longer the mutual fund is, the inferior performance is. It seems that someone says history is a valuable asset, but, historical burden might be too heavy to load occasionally.
