1. The biggest increase in a single day was set by our China stock market. The highest increase or decrease is probably thousands of increase or decrease. This is mainly because after the registration system came out, the GEM and the Science and Technology Innovation Board were listed on 1 day, and the ups and downs were unrestricted. I remember that when the Growth Enterprise Market was just launched and there were no ups and downs, there were thousands of new shares listed under the registration system. In one day, the price directly rose by ten or twenty times. But it will only happen on 1 and then slowly return to normal.
2. The normal price rises and falls in China A shares, and the normal price rises and falls by 10%, 20% and 30% respectively. Main board price 10%, growth enterprise market and science and technology innovation board price 20%, and newly launched Beijing Stock Exchange price 30%. Generally speaking, the greater the limit it sets, the higher its risk coefficient and the greater its probability.
3. because of the existence of price limit, the mode of playing the board has derived a profit model. The mode of playing the board is to buy one second before the daily limit today, and he will buy it. The highest price of the day will not be profitable on the same day. He usually has a very good premium when he opens the next day, so he will choose to sell when he is high the next day. This model was mainly carried forward by the Ningbo Death Squad at that time. There are a lot of short-term funds in the market now.
