Institutional post adjustment: Institutional post adjustment is mainly aimed at the first situation. After A shares are included in international indexes such as MSCI and FTSE Russell, this will happen before and after each expansion. Due to the unified operation of foreign passive funds, the stocks allocated by these funds will be greatly affected. In order to track the trend of relevant heavyweights with minimum error, they usually choose to sell in the late call auction.

Depress the stock price: This situation is mainly caused by the dealer deliberately suppressing the stock price and collecting chips. Because the activity of stock trading will be much worse at the end of the session, if the dealer collects chips at this stage, it will inevitably cause the stock price to rise, thus raising the buying cost. However, if the stock price is lowered by a few points in the late call auction stage, you can buy it slowly the next day, which will not lead to a rapid rise in the stock price.

Extended data:

Precautions:

Late trading, like early trading, has a time limit in call auction, and the last 3 minutes of the transaction is the late trading time in call auction.

Call auction's changes are definitely not the result of the sudden impulse of the banker, so we can look at the stocks that may change first in intraday trading and resumption of trading every day.

If a stock has a lot of low prices and big orders coming in and out today, it is likely to rise in the end.
