Once investors successfully subscribe for this fund, the fund company has full right to use the funds raised by this fund. After the fundraising, the fund is in a closed period. According to the judgment of the market, fund companies began to use funds to enter the market, buy planned targets and stabilize their positions. The interest of the remaining unused funds is also included in the fund profit, which is finally reflected in the total value of the fund, but the proportion is very small. Investors have no right to control interest, only the remaining funds subscribed in their own fund financing accounts are the discretionary part of users, and the interest belongs to the financing accounts. The above interest is calculated on a current basis.
