What is the biggest loss of the fund?
At most, the fund loses money, that is, the principal you bought is gone, but it will not be reversed. This situation is rare, because the fund is not like a stock. First of all, even if the fund is liquidated, investors can still get some funds. Equity funds lose 20% or 30% in most cases.
After buying a fund, don't just think about making money, learn to stop loss and take profit. When you find that the fund you bought has fallen by 30%, you can consider selling it, but you should analyze the reasons for its plunge. If the fund itself is not good, investors should sell it in time. If it is not the fund itself, it is the influence of the big environment. This situation can be persisted. When the next bull market comes, you can clear the position.
If you are worried that you can't grasp the trading point, you can choose the fund to vote. Most of the time, the fund's loss is maintained at around -20%, but some losses are as low as 55.70%, and the fixed investment fund can lose 50%-60% at most. If you can't catch the highest point, sell it when there is a downward trend, instead of holding it all the time.
After reading the above introduction, I believe you have a better understanding of what is the worst result of fund losses. If you choose a reliable fund, the worst result will be a temporary floating loss and eventually a profit.
