Funds with a holding period of one year cannot be redeemed in advance. It takes one year to redeem. One-year fund holding means that each fund share of this fund has a one-year lock-up period, and the fund shares reinvested in dividends are not limited by the lock-up period.
Generally speaking, although the fund may lose money, the possibility of not losing money is still relatively small, but it does not mean that it is completely impossible, depending on what fund it is.
