Before the call auction that opens every day, the Shanghai Composite Index falls a little, why?

Call auction is an auction before the opening, which refers to the 9:15-9:25 a.m. of each trading day, and investors are free to apply for buying and selling according to their own acceptable psychology.

During a call auction, real-time call auction references are revealed. The open call auction will be held from 9:15 a.m. to 9:25 a.m. The real-time display content includes **, **abbreviation, pre-****, virtual opening reference**, virtual matching amount and virtual unmatched amount; Declarations can be received from 9:15 a.m. to 9:20 a.m., or withdrawn from 9:20 a.m., and declarations can be received from 9:20 a.m. to 9:25 a.m., but they cannot be withdrawn.

Call auction You can enter the call auction according to the price of the previous day and the current day, enter all the orders placed by the computer host in the call auction time, and calculate the maximum volume according to the principle of priority and time priority, this is the transaction of the call auction, and this process is called call auction. After 9:25, you can see the transaction and quantity of each call auction.

Sometimes a certain ** cannot be completed because the **person gives ** lower than the ** given by the seller**, then, after 9:25 minutes, the column of the ** transaction price is empty. Of course, some companies stop trading for a period of time because they want to release news or hold a shareholders' meeting, so the transaction price column of the company's ** is also empty during the call auction.

Because the call auction is traded according to the maximum trading volume, for ordinary shareholders, at the call auction time, as long as the **** entered is higher than the actual transaction, the transaction can be traded, of course, if you buy at the limit price or sell at the limit price, the priority transaction is guaranteed. Therefore, if you want to buy first in the call auction, you can usually set the price higher, in order to get the right of first refusal, because your transaction price is a lower call auction. In addition, the number of ****** will not be very large, and it will generally not have any impact on the call auction of the **.

Because you can place orders before the call auction, all the ** pending orders listed on the Shanghai Stock Exchange are listed if the commission to sell is greater than the commission to buy, and the display is down. After the call auction, the system will automatically match the transaction according to the price, if the transaction ** is lower than the ** price of the previous trading day, then the Shanghai Composite Index opens negative (i.e., **), otherwise the opening turns red (i.e. **).

Caused by the ex-dividend of super ** shares.

Yesterday on the 14th, ICBC went ex-dividend.

On June 7, PetroChina's ex-dividend fell by 4 points before opening.

This month is the month of concentrated dividends and ex-dividends for ** shares.

The reason why an investor wants to buy a certain ** is because he believes that someone will buy this kind of ** from him at a higher **. As for the stock price, it doesn't matter, the important thing is that there are bigger "" willing to buy from you at a higher **. Song Huizong defended himself.

Song Huizong is still a well-informed person.

If the periphery is falling, just look at the European debt.

Institutional rebalancing: Institutional rebalancing is mainly aimed at the first situation, which occurs every time before and after the expansion of A-shares after they are included in international indices such as MSCI and FTSE Russell. Due to the passive unified operation of foreign capital, the allocation of these funds will be greatly affected.

In order to track the trend of the relevant heavyweight stocks with the minimum miscalculation, they usually choose to sell at the end of the call auction.

Suppression of stock prices: This situation is mainly due to the fact that the market makers deliberately suppress the stock price and collect chips. Because the activity of the transaction will be much worse at the end of the market, if the dealer collects chips at this stage, it will inevitably cause the stock price to rise, thereby raising the cost.

And if the stock price of Shibiansong is smashed down by a few points in the late call auction stage, it can be bought slowly the next day without causing a rapid increase in the stock price.

Expand the search for information:

Note: The last session is the same as the morning session, the call auction has a time limit, and the last 3 minutes after the end of the transaction is the time of our final call auction.

There is a change in the call auction, and it is absolutely impossible to be the result of the sudden impulse of the bookmaker, so we can take a look at the possible change in the daily intraday and review the **.

If there are a lot of ** votes today, there are a lot of ** relatively low and large orders in and out, then it is very likely that there will be a pull up at the end of the market.

The trend of ups and downs really depends on luck.

Why did the end of the call auction plummet by 2 points the day before a ** was included in the SSE 50?

This situation is relatively rare, probably because of the fear of being shorted.
