If investors achieve the expected return, they can sell; If investors fail to achieve the expected return, they can continue to hold the fund, and it is meaningful to hold the fund for a long time.

Investors set a profit-taking target, for example, the investor's profit-taking target is 20%, then when the fund's profit reaches 20%, it will stop making profits. If investors are not sure about the fund's later trend, they can stop the profit by half first, and then stop the profit by half when the fund continues to rise, until all the funds are sold.
