China's 'Miracle Stock' Crashes 67% Just Days After IPO
Six days after ringing the bell at the Shanghai Stock Exchange, Chinese industrial equipment maker Shengu Group is discovering how fast euphoria can turn to vertigo. Shares in the Shenyang-based manufacturer of giant compressors hit their daily limit-down on Thursday, trading around 27 yuan. That is a fall of more than 67 percent from the peak of 82.59 yuan reached just one day after listing. In less than a trading week, roughly 170 billion yuan, about 24 billion US dollars, has been wiped from the company’s market value.
The numbers tell the story of a classic boom-and-bust. Shengu went public on September 17 at an offer price of 4.39 yuan per share, valuing the company at just under 30 times annual earnings. In its first two sessions, speculative money sent the stock soaring, briefly lifting its market capitalization to around 250 billion yuan. By Thursday, that figure had shriveled to roughly 84 billion yuan, one of the sharpest reversals for a newly listed Chinese company in recent memory.
There is an irony in the target of all this attention. Shengu is not a flashy artificial intelligence startup or a consumer darling. It is a decades-old heavy industry name from China’s northeast, best known for large centrifugal compressors, the machines that act as the beating hearts of refineries, chemical plants and gas pipelines. Its business is steady, capital-intensive and deeply unglamorous, which is exactly why the vertiginous ride in its shares has left many seasoned market watchers shaking their heads.
The mechanics of China’s market for new listings help explain the frenzy. New shares are typically priced conservatively at their offer, and only a small fraction of stock is freely tradable at first. Retail investors, who dominate day-to-day trading, have long treated debut listings as lottery tickets, betting that scarcity will drive prices up no matter the fundamentals. At its peak, Shengu traded at nearly nineteen times its offer price, a level sustained for barely a day before gravity reasserted itself.
Nor has the appetite for new listings faded. On the very day Shengu was hitting its limit-down, Changzhou-based biotech firm Bairuiji made its debut on the Beijing Stock Exchange, opening 347 percent above its offer price and at one point trading up 477 percent. The broader backdrop is equally striking: China’s benchmark Shanghai index stands near 3,888, up about 45 percent over two years, and the total value of listed shares has swollen by roughly 51 trillion yuan since September 2024.
Even after the crash, Shengu still changes hands at several times its offer price, a hint that some froth remains in the stock. Analysts point to the familiar gap between price and fundamentals: a compressor maker with solid but slow-growing industrial earnings struggles to justify a valuation built for a hot technology story. When the music stops, small floats amplify the fall as decisively as they amplified the rise.
For global investors watching China, the episode is a useful case study. The two-year rally has produced impressive headline gains, but the benefits have been unevenly spread, and speculative pockets clearly persist. Newly listed shares, with their thin floats and eager retail followings, remain the most volatile corner of the market, capable of delivering both spectacular pops and brutal reversals within days.
Shengu’s rollercoaster will not be the last of its kind while enthusiasm for new listings runs this hot. But it offers a vivid reminder for anyone tempted to chase the next dazzling debut: in China’s resurgent market, the distance between ringing the opening bell and facing the music can sometimes be measured in days.
