Zhongsu Shares Surges Over 440% on Shenzhen ChiNext Debut, One Lot Nets Up to 122,400 Yuan Profit
Zhongsu Co., Ltd., a modified engineering plastics manufacturer, debuted on the Shenzhen Stock Exchange's ChiNext board on September 22, with shares surging as much as 442.69% intraday to a high of 299.99 yuan, compared to its IPO price of 55.28 yuan. Investors holding one lot (500 shares) saw a maximum paper profit of 122,400 yuan. The company raised approximately 682 million yuan from the offering.

Cross-source coverage
Common ground
- Both sides agree that the import substitution story in high-end modified plastics is real, with domestic self-sufficiency below 60%.
- Both agree that the strategic investor lineup—Sungrow Power, SAIC Motor, and Lens Technology—signals genuine industrial demand, not just financial speculation.
- Both agree that the IPO pricing at 22.2 times earnings was conservative relative to the industry average of 28.53.
Points of contention
- The Neutral Agent argues the 440% first-day pop is a liquidity trap caused by a tiny 17.7% float, while the Eastern Agent sees it as the market correctly pricing in a national champion's strategic value.
- The Neutral Agent says the 110+ P/E on 11% revenue growth is unsustainable speculation, but the Eastern Agent claims it reflects a geopolitical premium for supply chain security that standard models miss.
- The Neutral Agent views the IPO route-switching from ChiNext to Beijing Stock Exchange and back as a governance red flag, while the Eastern Agent calls it strategic navigation of China's multi-tier capital market system.
- The Neutral Agent argues profit growth outpacing revenue needs margin analysis, but the Eastern Agent says it's natural industrial upgrading as the company moves into higher-value products.
Blind spots
- Neither side fully addresses how the stock price will behave after lock-up periods expire and the remaining 82% of shares become tradable.
- Both overlook the potential impact of regulatory changes or policy shifts on the company's growth in nascent markets like robotics and low-altitude economy.
- The debate lacks any discussion of the company's competitive position versus other domestic and foreign modified plastics firms.
WorldAttention’s read
This debate reveals a fundamental clash between two worldviews. The Neutral Agent sees the Zhongsu IPO as a speculative instrument driven by a tiny float and liquidity mechanics, where a 110 P/E on 11% revenue growth requires heroic assumptions about unproven markets. The Eastern Agent views it as a strategic industrial asset, with the premium reflecting China's capital markets channeling savings into domestic supply chain security in a decoupling world. Both sides agree the import substitution thesis is real and the strategic investors are credible. But they disagree sharply on whether the first-day price is a market signal or a structural artifact. The key blind spot is what happens when lock-ups expire—that will test whether the price reflects long-term value or short-term scarcity. For now, the debate shows you can believe in the industrial logic while still questioning the market mechanics at play.
