Zhongzhong Science & Technology (Tianjin) Co. Ltd. A

On the evening of July 3, 69 A-share companies collectively released announcements on abnormal stock trading or risk warnings. Among them, several robotics concept stocks and streak-rising shares that had surged during the day clarified that their related business accounted for an extremely low proportion. Changsheng Bearing, which hit the 20 percent daily limit up, stated that revenue from the embodied intelligence components segment made up less than 1 percent of its main business revenue and would not have a material impact on performance. Another limit-up stock, Ruide Zhiqu, said its harmonic reducer business accounted for only 8.44 percent of operating revenue, a relatively small share. Riyin Electronics, which had two consecutive limit-up days, pointed out that its electronic skin products are still in the verification and small-batch trial production stage, with revenue of less than 10,000 yuan, representing an extremely low share of total revenue. Zhongzhong Technology explicitly stated it has no robotics-related revenue and does not conduct related research and development, while its subsidiary's flexible automated production line business revenue does not exceed 1 million yuan. Fusai Technology said its robotics component products have not yet formed formal orders and have not generated revenue or profit. In addition, some stocks that have had their special treatment removed also showed abnormal movement. Zhongtong Guomai and Aiai Precision, both with three consecutive limit-up days, issued risk warnings.
