call auction - Boben's thinking within 15 minutes
If you have not paid attention to call auction before and always thought it was 9:30 opening , then you are still some distance away from being a professional trader. It is recommended to spend the time watching the market. Arrive as early as 9:00, and sit in front of the computer at 9:15 at the latest. In these 15 minutes, the stock price can be said to change rapidly, especially when the main funds test market and the main funds do not actively participate in allowing the market to trade naturally, it is normal for the stock price to jump 5% in an instant.
The 15-minute trend of the call auction has a gray background to distinguish it from the formal trading throughout the day. The real difference is that the price during the call auction is not the actual transaction price, but based on the order at that time, guaranteed. The price calculated under the premise of the largest trading volume represents the current market expectations of both long and short parties. If the orders used by both long and short parties to express their willingness to buy and sell are inherently false and tentative, it will be impossible to evaluate the reference value of this price. There are two trading volumes corresponding to the price during the
call auction. The trading volume extending upward is the trading volume that can be achieved by buyers and sellers at that time. If it is green, it means that there are more entrusted sell orders than entrusted buy orders at that time. If it is red, it means that there are more entrusted buy orders at that time. More than commissioned sell orders. The trading volume of the downward extension of the volume bar is the trading volume of the entrusted volume at that time which exceeds the tradable part. If the trading volume of the entrusted buy order is greater than the trading volume of the entrusted sell order, the downward volume bar will be red; if the entrusted sell order at that time is If the trading volume is greater than the trading volume of the buy order, the downward volume bar will be green.
Call auction operation stock price method
Actively long the stock price
Call auction The characteristics of active long stock price:
The overall stock price trend rises during the call auction;
During the call auction, the matching trading volume gradually becomes larger, and the volume bar is red;
Call auction During the period, the order volume that is more than the matching trading volume gradually becomes larger, and the volume bar is red.
Illustrated case
As shown in the figure, the stock price of Tianwo Technology (002564) rose slowly during the call auction that day, the matching trading volume and the commission volume exceeding the matching trading volume slowly became larger, and the commissioned buying volume was significantly more than The volume of entrusted sales shows obvious signs of reluctance to sell in the market. However, judging from the trend of the call auction, at least during the call auction period, the main funds did not obviously participate and actively do long performance. Therefore, when encountering such a call auction market, you need to wait for further observation after the market opens before making a trading decision.
As shown in the figure, the creative information (300366) call auction opened high and traded sideways at a high level. The matched trading volume was once enlarged, but the commission volume that was more than the matched trading volume did not change significantly. During the call auction, the long and short energy It is balanced, and there is no obvious bias towards one side. At least it is difficult to see the possibility of a positive rise in the stock price on that day. After the opening, the stock price dived directly into the green zone, and the overall trend became weaker. Caution was the main focus of operations that day.
As shown in the figure, China Unicom (600050) opened slightly higher during the call auction. The stock price remained sideways during the entire call auction period, but the matching volume was gradually enlarged, and the volume of orders that exceeded the matching volume was also gradually increasing. In the enlarged state, it was not until the opening price was generated at 9:25 that the commission volume, which was more than the matched trading volume, began to decrease. There is not much clue from the price during the call auction period, but from the trading volume of China Unicom during the call auction period on the same day, we can find that the main funds and market follow-up funds are actively doing long, and the trend of the day is worth looking forward to.
Active short selling stock price
Characteristics of active short selling stock price during call auction:
The overall trend of stock price falls during the call auction;
During the call auction, the matched trading volume gradually becomes larger, and the volume bar is green;
During the call auction, the matched trading volume is more than the matched trading volume The commission volume gradually becomes larger, and the volume bar is green.
Illustrated case
The picture below is a typical call auction market with a weak trend. The price dropped directly to the limit at 9:15, and the stock price stayed at the lower limit during the entire call auction period, and the trading volume was more than The volume of commissions that match trading volume has been increasing. The most important thing is that the ever-increasing trading volume and commission volume are mainly based on active selling. However, transactions were not active throughout the day, and neither the volume during the call auction period nor the overall volume throughout the day was significantly enlarged. Therefore, the market was still actively bearish, and it was not caused by deliberate selling by the main force.
As shown in the figure, the stock price of Dahua Intelligence (002512) continued to decline during the call auction, and the matched trading volume continued to increase. There was no obvious shift in long and short energy, and the commission volume that exceeded the matched trading volume was not too large. , so the trend during the call auction period leads us to the conclusion that the stock price trend on that day will not be very optimistic. The stock price fluctuated sideways at a low level throughout the day. Although it hit the lower limit, it still opened from time to time. The collective bidding of
Fujian Jinsen (002679) is the most important one to guard against. At the initial stage of the call auction, the stock prices were still in the red zone, and some stocks could even rise by more than 5%. However, this was just a flash in the pan, and the stock prices kept falling. By the time the market opened, the stock prices had fallen to the green zone, and some even fell to around 5%. As shown in the figure, the price of Fujian Jinsen during the call auction period increased by 2% to fell by 2%. Judging from the changes in volume and energy, the participation of main funds was not high, and it was difficult to get out of a beautiful long market that day.
If the long and short are inconsistent, you need to wait and see after the market opens.
During the call auction, after a comprehensive analysis of the factors we introduced earlier, we found that many times during the call auction, a very obvious directional market cannot be found, or the market may occur in just 15 minutes. A shocking reversal, when faced with these situations when the market opens, you must wait until the market opens before making a decision.
Illustrated case
As shown in the figure, the trend of const (300445) on that day can be described as "unparalleled". The call auction hit the daily limit and fell slightly at the opening. The matched transaction volume during the call auction period was more than matched transactions. The volume of commissions has no obvious amplification characteristics, and there is no obvious consistent long-short behavior in the market, so we need to wait and see further after the market opens. The stock price plummeted immediately after the market opened, and then fluctuated at a low level close to the limit.
During the call auction of Zhongqian Shares (300526), the stock price fluctuated violently, but from a volume perspective, there was no sign of active participation of main funds, indicating that the market was dominated by natural transactions that day, and it was difficult to have a good market throughout the day. So mainly wait and see. The trend of collective bidding of Wanheng (600241) in the
era is also a manifestation of attracting bulls. The volume in the early stage of collective bidding is very beautiful, and the price of the transaction has always been the upper limit price, but before 9:20, the front price was All orders were cancelled. If retail investors who follow the trend place orders at the daily limit price before 9:20, and find that a large number of orders have been canceled from 9:20 to 9:25, their orders cannot be canceled and they have to wait until 9:25 to be executed. Once the trading volume of the call auction at 9:25 is the largest volume in the call auction in recent days, it is basically certain that the main force is shipping.
The collective bidding of Nanning Department Store (600712) is the most common situation among more than 3,000 stocks every day. The transactions are light and the prices do not rise or fall much. Such collective bidding can give us very limited information, so we cannot rely on the collective bidding. Trading decisions are made through bidding, so we should focus on stocks with obvious changes in volume and price during the call auction period.
When studying call auctions, you must take into account the current position of the stock price. As mentioned above, you must first find the big direction and then study the small details, otherwise you will do a lot of useless work.The Sanjiang Shopping in the picture below had a serious divergence in its stock price during the call auction on December 1 after six consecutive one-word boards appeared. The amplitude exceeded 15%. The stock price continued to rise only in the last two days. Increase the volume, but the The turnover rate on one day was 7.63% and the turnover rate on the next day was 10.97%, which is far from the turnover rate standard for main capital shipments. It is very normal to use collective bidding to wash the market at this position. Determining this standard is very important for the market outlook. The trading decision is very clear.
