Investors need to reasonably judge the cost performance of this fund when making related investments. We just need to buy the fund within the risk we can bear. For the volatile market, we can insist on fixed investment, even if there is short-term loss, but the investment is not much, and the burden we can bear is relatively small.

For investment funds, we never know when we will make money and when the foundation will lose money, so we should quit in time. We can only inquire about relevant information, and we can decide whether to invest after we have a deeper understanding of such funds.
