Double dip refers to the market falling to the original low after the previous low. However, if the market continues to be optimistic, investors will buy at a low level, and prices may rebound or enter a state of shock, forming support at this lowest level.

If there is a double dip in the market, it is a good signal and fund investors can regard it as a good buying opportunity. However, we should still pay attention to whether the support level will continue to be effective and whether the market will fall again.
