There are two ways to buy a fund at a high point: the first way is to stop the loss in time, the fund itself fluctuates little, and the short-term trading loss will not be too great. It can replace other low-level funds for investment without losing time and cost.

The second way is to make up the position after the callback. When the fund falls, it can cover the position in batches, and the cost of the fund will be reduced after covering the position. In this way, the investment time will be longer, the time cost will increase and the risk will be greater.
