If the fund is a high-quality fund, you can continue to hold it and add positions after the decline. The lower the cost, the lower the risk that investors take, and the higher the probability of returning to the capital or making money in the future. If the fund is not a quality fund, it can be sold.

High-quality funds can withstand the market decline, although they will follow the market adjustment, but the probability of subsequent rise is greater. High-quality funds can be selected from three aspects: fund manager (long-term fund manager or star fund manager), fund historical performance (good historical performance) and fund maximum withdrawal (the smaller the maximum withdrawal, the better).
