It is better to sell high and buy low if you buy a fund. Buying funds does not make money. First of all, you should consider whether the timing of your purchase is wrong. The so-called timing is that the fund seizes the opportunity of falling to buy. Only by buying low can we sell when the fund rises in the later period and earn more expected returns. The lower the starting price, the greater the increase in the later period, and the more obvious the expected income. No matter what kind of fund, you can always make money by buying low and selling high. Buy low and sell high, not buy at the lowest point, but sell at the highest point. The correct way is to buy in the low price range and sell in the high price range. The advantage of this is that it can reduce the risk and make the expected return slightly certain. If it is the operation of the lowest point and the highest point, it is undoubtedly full of many uncertainties.
