For Chen Yansheng, the self-made 'Toy King' of Guangdong’s Chenghai district, a single regulatory filing has achieved what years of industrial manufacturing could not. In just four trading days, Chen’s family wealth surged by approximately 2.7 billion yuan ($370 million) following an announcement that his firm, Xinghui Environmental Materials, would welcome a high-profile indirect investment from Jiushi Intelligence. The stock price of the polystyrene manufacturer skyrocketed by over 85% as investors scrambled to price in a future where traditional plastics meet cutting-edge autonomous driving.
Jiushi Intelligence, a unicorn valued at over 10 billion yuan, is the world’s largest operator of Level 4 autonomous delivery vans. Having recently integrated Alibaba-backed Cainiao’s unmanned vehicle business, the company now manages a fleet exceeding 20,000 'RoboVans.' Their entry into Xinghui’s shareholder list—acquiring a 27.49% indirect stake for 1.18 billion yuan—has ignited a speculative frenzy. Market participants are betting that the partnership will transform a legacy chemical company into a strategic player in the 'New Materials plus AI' ecosystem.
However, the financial reality of Xinghui Environmental Materials provides a stark contrast to the market’s exuberance. The company’s most recent earnings report shows a 21% decline in revenue and a devastating 44% drop in net profit. Before this sudden surge, Chen Yansheng had even dropped off the Hurun Global Rich List, burdened by the persistent losses of his Spanish soccer club and the stagnation of his core gaming and toy businesses. The current rally appears to be driven by sentiment rather than a fundamental shift in the company’s earning power.
The '36-month' caveat remains the most significant hurdle for long-term bulls. In its regulatory disclosures, Jiushi Intelligence explicitly stated it has no plans to seek control of the company or inject any assets into the listed entity for the next three years. This mirrors previous speculative cycles in the A-share market, such as those involving human-robotics firms, where stocks surged on the promise of 'tech-transformation' only to collapse by 40% to 60% once the hype cycle exhausted itself and regulatory scrutiny intensified.
As of early April 2026, the trading volume for Xinghui has reached fever pitch, dominated by 'hot money' and retail investors chasing the momentum. While the paper wealth of the Chen family has ballooned, the stock’s price-to-earnings ratio now stands at a staggering 86.6 times, nearly triple the industry average. This disconnect between a struggling chemical manufacturer and the lofty valuation of an autonomous driving future suggests that for many investors, the eventual 'mean reversion' may prove as rapid as the initial ascent.
