Funds are different from deposit products in terms of capital preservation and interest protection. Even the money fund with the lowest risk has the risk of losing money in extreme cases. As an investor, you must have this kind of risk awareness before buying and make your own investment choices according to your risk preference and anti-risk ability.
If the loss is serious, it is obviously not a money fund, because the short-term fluctuation range is too large, but it should be a hybrid or equity fund.
