It is better to sell part of the fund, which can not only guarantee part of the income, but also prevent missing the follow-up market. Investors can sell half after making profits, the fund will continue to rise and then sell half, and so on until it is all sold. If investors think that the follow-up market is not good, they can sell it all at once.

Fund sales should be based on profit. If investors are losing money, then adding positions is a better choice.
