The cross-sectional difference of funds is the main factor affecting investment decisions of mutual funds. Thus, the research is to study the cross-sectional difference of the return, turnover, and risk of the funds to compare the effects of fund size and fund type. The monthly data of open-end funds in Taiwan from Jan. 2003 to Dec. 2013 were analyzed with panel data model to investigate the cross-sectional difference of Taiwan’s equity funds. The results showed the cross-section difference of the fund size is positively related with that of the fund return. The effect differs with the type of the fund. The cross-section difference of the fund size is negatively related with that of the fund turnover. Significant differences exist with different type of funds. The cross-section difference of the fund size places no significant relationship with that of the fund risk. Different types of funds pose no significant difference on such effect.
