Buy funds at a low price, reduce costs and cover positions. Covering positions means that investors buy similar securities on the basis of holding a certain amount. To make up the position is to buy because the fund has fallen, so as to reduce the cost of the fund.

Covering positions is a passive contingency strategy after being locked up. It is not a good method to solve the problem in itself, but it is the most suitable method in some specific situations. However, investors should not blindly cover positions, and make corresponding analysis before covering positions.
