On the evening of March 27, there were four new shares registered on the main board in the Shanghai and Shenzhen stock markets that disclosed the issuance results. So far, 10 main board enterprises in Shanghai and Shenzhen under the comprehensive registration system have completed their inquiry and pricing. From the perspective of the issuance results, most enterprises have set an issuance price that breaks the "23 times P/E ratio", which means that the era of "23 times P/E ratio" in the main board IPO market has come to an end. Industry insiders pointed out that under the comprehensive registration system, the market-oriented issuance mechanism has been continuously improved, and it is expected that the price difference between the primary and secondary markets in the new stock market will be reduced. The risk of breaking the IPO in the initial stage of listing will increase compared to the approval system, and the trading mechanism will also change compared to the approval system. Investors should fully understand the issuance and trading rules under the registration system, assess their own risk tolerance, make prudent decisions, and rationally participate in subscription and trading.
