After the fund expires, investors can choose to redeem or continue to hold it. If the fund performs well, investors can choose to continue to hold it in order to obtain higher returns. If the fund does not perform well or investors need funds, they can choose to redeem it. However, it should be noted that there may be costs such as taxes and fees after the fund expires, which need to be considered according to specific circumstances. Therefore, the fund does not have to be redeemed when it expires.

At the same time, we should also pay attention to the redemption regulations and fees of the fund to avoid additional expenses caused by redemption.
