The suspension of fund subscription and redemption means that the fund cannot trade for the time being. Under normal circumstances, the subscription and redemption will be suspended under the following circumstances:

1. The Fund is in a closed period. In order to ensure the scale, closed-end funds suspend subscription and redemption during the closed period.

2. Control the growth scale of the fund. The bigger the fund, the better. Because the management ability of fund managers is limited, in order to prevent idle funds, the fund size will be controlled by suspending subscription.

3. Major changes have taken place in the stocks held, and the transferred stocks may fluctuate greatly, resulting in a large number of purchases and redemptions by investors. Fund companies generally suspend purchases and redemptions.
