Generally the minimum is 5 years. The variability of fund size is different. Closed-end funds have a clear duration (not less than 5 years in China), during which the issued fund shares cannot be redeemed. Although this kind of fund can be raised under special circumstances, it must meet strict legal conditions.

Closed-end investment funds pay investors in the form of dividends, interest and realizable capital gains after receiving income. Although the unit price of closed-end investment funds is based on the net asset value of the funds.

However, it changes with the change of supply and demand in the securities market, or it is higher or lower than the net asset value of the fund, which is not necessarily equal to the net asset value of the fund.

Extended data:

The main difference between closed-end funds and open-end funds lies in whether the fund share can be redeemed or whether the fund scale can be changed. The share of closed-end funds cannot be redeemed, so the total capital is fixed; The share of open-end funds is redeemable, so the total capital is variable.

Judging from the market operation and market operation rules, the trend that the stronger the stronger should not change much in the short term, so when we choose funds under the same circumstances, we need to give priority to those funds whose unit net value has increased better since the beginning of the year.
