A 30% increase in fund positions is a better way to operate. After the fund position was adjusted back, the net value of the fund decreased. At this time, the cost of buying funds is lower. The more fund shares the same money buys, the later funds will fall again. Investors can add positions again and increase their positions by buying regularly.

When the fund rises gradually, investors stop buying and continue to hold it. When the fund income reaches 20%-30%, investors will gradually lighten their positions by selling regularly.
