If the fund falls, you can first understand the reasons for the decline of the fund. Short-term decline will not affect the long-term trend of the fund. Investors need to comprehensively consider factors such as market conditions and the location of funds. If the market situation is not good, investors can choose to sell the fund. If the market is good, investors can appropriately increase their positions when the fund falls, thus reducing the investment cost.

When the fund falls at a high level, investors can sell the fund, and high-level investors take higher risks. When the fund falls at a low level, adding positions is a better operation mode, which can reduce the cost of the fund.
