A: It is generally recommended that the rate of return of the fund after profit is 15%-20%. When it reaches this profit rate, it can generally be sold. However, this is an approximate rate of return, which needs to be judged according to the funds actually bought by investors. Different investors invest different amounts. If you don't know how much you can sell, investors can set some profit-taking values themselves, and when they reach the profit-taking target, they will automatically sell profit-taking.
