On the evening of February 6, the Shenzhen Stock Exchange issued an announcement stating that from February 2 to February 6, it had taken self-regulatory measures against 233 instances of abnormal securities trading activities. These involved practices such as intraday price manipulation and fictitious orders. The exchange placed heightened monitoring on Jiamai Packaging and Fenglong Co., Ltd., whose share prices had experienced significant abnormal fluctuations recently. Additionally, the exchange verified eight major corporate events and reported four clues of suspected illegal activities to the China Securities Regulatory Commission.
It is noteworthy that Jiamai Packaging had previously suspended trading for verification. On January 25, Jiamai Packaging announced that its stock price had surged by 408.11% between December 17, 2025, and January 23, 2026, repeatedly triggering abnormal trading volatility alerts. The company stated that the sharp price increase in a short period had deviated from its fundamental value. To protect investor interests, the company would suspend trading to verify the trading fluctuations.
After a one-week suspension, Jiamai Packaging resumed trading on February 2. In its resumption announcement, the company clarified that it is not involved in robotics or robotic vacuum cleaner businesses. Its primary operations remain the R&D, design, production, and sales of food and beverage packaging containers, along with providing beverage filling services. The company confirmed no significant changes in its production, operations, market environment, or industry policies, and expects no major shifts in its core business over the next 12 months.
Following the resumption, Jiamai Packaging's stock maintained an upward trend. Wind data shows that from February 2 to February 6, its stock price accumulated a gain of 12.17%, with its latest market capitalization reaching 28.5 billion yuan.
The significant rise in Jiamai Packaging's stock price is primarily linked to a change in its controlling stake. On the evening of December 16, 2025, Jiamai Packaging announced that its controlling shareholder, China Food Packaging Co., Ltd., had signed a Share Transfer Agreement with Suzhou Zhuyue Hongzhi Technology Development Partnership. Upon completion of the relevant equity changes, the company's controlling shareholder will shift to Zhuyue Hongzhi, and the actual controller will change to Yu Hao.
Fenglong Co., Ltd. also saw some of its investors face trading suspensions. The company had previously halted trading due to a substantial short-term price surge, with certain investors suspended by the Shenzhen Stock Exchange. On the evening of January 23, the exchange announced that Fenglong's stock had shown severe abnormal volatility, and some investors had engaged in irregular trading behaviors disrupting normal market order. Regulatory measures, including trading suspensions, were imposed on the involved investors.
On the evening of January 25, Fenglong Co., Ltd. announced a trading suspension for verification, noting its stock had risen by the daily limit for 17 consecutive trading days from December 25, 2025, to January 23, 2026, accumulating a 405.74% price increase. The company warned of significant accumulated trading risks, a clear deviation from market trends, and potential rapid price decline risks. Trading was suspended starting January 26.
Fenglong resumed trading on February 2. According to Wind data, on February 6, its stock fell by the daily limit, closing at 104.85 yuan per share, with a latest market cap of 22.9 billion yuan. From February 2 to February 6, the stock accumulated a 5.35% gain.
The surge in Fenglong's stock price is mainly attributed to an acquisition offer from humanoid robotics leader UBTECH ROBOTICS. On the evening of December 24, 2025, UBTECH ROBOTICS announced its intention to acquire a portion of Fenglong's shares. Fenglong concurrently announced that upon completion of the share transfer and registration, along with the waiver of voting rights, its controlling shareholder would change from Chengfeng Investment to UBTECH ROBOTICS, and the actual controller would shift from Dong Jiangang to Zhou Jian.
