Recent studies have reported that open-end fund has its performance persistence. However, those studies didn¡¦t mention the factors of performance persistence. Therefore, investors knows the character of the types of fund, but unable to determine which individual fund have the character given the type of fund.

Samples in the study are chosen from 160 Taiwan open-end equity funds during 2004-2011. The return rate data is rolling data. In order to remove the difference of the risks of the funds, simple return rates were transferred into Jensen¡¦s Alpha. The conclusions are shown as below¡G 1. In short term, Time of Establishment often has a positive effect on fund performance persistence. 2. In short term, Net Asset Value often has a negative effect on fund performance persistence. In long term, net asset value often has a positive effect on fund performance persistence. 3.
