Generally speaking, closed-end funds are relatively profitable because of their early issuance and high discount. For example, since 500002 and 500008 were held in 1999, the average annual income has exceeded 30%, and 15-20% is slightly worse. Better varieties of open-end funds also have higher returns, such as Harvest 300, which has an average annual income of 46% since it was held in 2005. Generally speaking, as long as it is not bought above 6000 points in Shanghai, the average annual income is around 10%.
