The probability of the principal loss of the fixed investment fund is extremely small, and there is basically no need to set a stop loss point. However, for the safety of funds, the fixed investment cannot be invested all the time. It is best to set a take profit point and sell it at this point.

The profit point of fixed investment funds is generally set at 20%-30% of the profit, with the average price-earnings ratio of confirmed books in the past five years as a reference. The higher the average level, the lower the take profit point is set. The lower the average, the higher the take profit point setting. In addition, the dynamic profit-taking method can also be used, and the profit-taking point will not be continuously improved. The rate of return fell by more than 5% and immediately took profit.
