Generally speaking, if the stock price starts to rise after the opening of the down limit, it means that the news that caused the stock price to be negative has been exhausted and the market outlook may rebound; If the board is closed after opening, the market outlook may be adjusted for a period of time.
For individual stocks, it is easier to attract investors to enter the market repeatedly than to open the daily limit until the end of the session. This operation is also easier to ship than when the daily limit is never opened. Therefore, some powerful bookmakers will absorb goods in this position, and some weak bookmakers will be out in this position. The specific operation still depends on the position of individual stocks.
