If possible, after the fund subscription is over, it is best for investors to confirm that the fund denies the successful subscription on the trading day or the afternoon of the second trading day. The main reasons for the failure of fund subscription are as follows:

1. The subscription amount does not meet the minimum requirements for fund subscription. For example, the minimum requirement for fund subscription is 10000 yuan, and investors only subscribe for 5000 yuan, so the fund subscription is unsuccessful.

2. During the subscription period, the fund has raised enough funds, so it is also unsuccessful for investors to subscribe for the fund.
