1. 10 day deviation 100%, suspension for 5 days. This deviation does not mean that it will rise from 1 to 2, even if it is 100%. Instead, the daily deviation value is added up, and the daily deviation value = stock increase-growth enterprise market increase (399 102). For example, on the 23rd, Yimikang rose by 20%, and the Growth Enterprise Market rose by 2.68%. So the deviation of Imikan today is 20-2.68= 17.32%. The deviation of 10 day does not represent the accurate calculation of 10 day, but the maximum deviation within 10 day. For example, after a stock has two daily limit, it starts five daily limit, and then calculates the deviation from the first daily limit. Not from the limit. That is, when it falls, however, as soon as it starts to rise, it starts to calculate the deviation.
2. If 10 is changed three times in a day, the suspension will be suspended for five days. That is to say, even if the change is announced three times in 10 days, it will be explained once from the day when the change announcement is first published, not from the start date of the first change. I'll use it later. For example, a GEM stock has a daily limit of 1 in February, a closed board on February 2, and reverse packaging on February 3. If the increase exceeds 30% in these three days, the change will be triggered and the company will announce the change on the third day. If you make three changes on day 10, it will start on February 3rd instead of February 1 day. A deviation of 30% from the growth rate of GEM 3 will trigger the change. The increase of No.3 main board deviated from 20%, which triggered the change. Similarly, this three-day increase is not accurate for three days. If this deviation is reached within two days, then the two-day increase will be the same as that of 10 day 100%. Not from the time of decline, but from the day when it began to rise.
Rules for the second suspension of GEM:
The second suspension rule, written in the document, is the second suspension when the deviation reaches 200% within 20 days, but there are basically no stocks, so I only write the second suspension rule I think, which is also the reason why Shangneng Electric and Yaben Chemical suspended their trading. In my opinion, the second suspension rule is: after the first suspension and resumption of trading, it will trigger another rise and continue the second suspension. The second pause is 10 days.
Shenzhen Stock Exchange
The Shenzhen Stock Exchange does not have a document to write the suspension rules, but it can be deduced from these suspensions. Here, in Shenzhen, three stocks were suspended in the past six months. Yujing, Sanyangma and Zhejiang Jiantou have all been triggered. The four changes of 10 day are the same as those of GEM. The first change is the calculation date from the change date. The main board rose more than 20% on the 3rd. Even if there are changes, it is actually good. On the dragon and tiger list. Change it in three days. Don't read the change notice. Some people will say that Jiuan has risen so much that 10 has not triggered the fourth change. I actually counted it yesterday, but I really didn't. Last year, I also wondered why I stopped playing for a long time and traded Yujing instead. Now I understand. The second suspension of Shenzhen Stock Exchange should be similar to that of GEM, that is, after the first suspension, if there is another transaction, the second suspension will be 10 trading days.
