1. First, the quality of these new shares is average. Among the four new shares, only Gong Kun Science and Technology has the bright spot of energy storage, while the other three have little.
2. Second, the IPO valuation does not match the quality. At present, the average valuation of the North Exchange is more than 20 times, and Tian Ming Science and Technology and Liandi Information are issued at a price-earnings ratio of 24 times. It is not unexpected to fall below the price. Many investors were optimistic about Tian Ming Science and Technology before the subscription, believing that it would rise sharply after listing.
