Whether the fund is sold or not is not how much it is bullish, but whether it is expensive or not.

If 1 yuan is used to buy the fund, it will increase by 50%, reaching 1.5 yuan, but it is worth 2 yuan. You could have earned 100%. If you sell it at this time, won't you lose 50%?

Another problem is that it is a wrong choice to sell the investment of fixed investment strategy every time when we don't need money urgently. Because after 10, the price of every purchase can't be lower now.
