First of all, investors can set a stop-loss point, which can stop profits when the fund's profit reaches the stop-loss point, or stop losses when the fund's loss reaches the stop-loss point.

Fund take profit: it is uncertain whether the fund will rise in the future. You can stop the profit by half first and guarantee some income. The fund will continue to rise and then stop making half of its profits until the fund is sold. When the fund falls after reaching the expected return, investors can completely take profit.

Fund stop loss: after the fund loses money, it can be sold completely or exchanged for shares. It is not necessary to stop the fund from falling, but it is also possible to increase the position to reduce the cost. After the cost is reduced, the risk is reduced and the probability of returning to the original is greater.
