Investors can increase their positions if they have losses, and the losses can be reduced. The lower the cost, the less risk investors will take, and the greater the probability of returning capital or generating income in the future. However, investors should judge whether the fund is a quality fund, and the quality fund will cover the position. If investors are in a profitable state, there is no need to add positions, which will increase the cost of investors. The higher the cost, the greater the risk that investors bear and the greater the probability of future losses.

Investors set a goal of adding positions. For example, if investors' goal of adding positions is 10%, they will start adding positions when they lose 10%. Adding positions is usually not done at one time. When the fund falls to 10% again, they will add positions again, and so on, until the adding positions are finished, and stop adding positions when the fund starts to rise.
