Generally speaking, there is a significant increase in the weight of stocks, and the market is buying heavily to seal the daily limit. There is still a lot of buying. If you buy a lot but no one sells it, it means no one is bearish. Everyone feels that there is still room for further improvement. At least in the short term, it will continue to rise in the original direction until the market feels that it is no longer undervalued.
The daily limit is just the opposite of the daily limit. But it's also true. When everyone is bearish on this stock, they can't find anything to buy only when they sell it. Of course, they can only continue to look for support in a short time. Until the market feels that it has fallen in place.
