UBTECH ROBOTICS (09880) saw its shares plummet 5.09% during intraday trading on Thursday. The sharp decline came amid a broader sell-off in the industrial machinery sector.

The movement appears linked to a market analysis report highlighting challenges within China's burgeoning humanoid robot industry. The report, citing UBTECH's own founder, noted that humanoid robots in Chinese factories currently remain "only half as efficient as humans." This revelation raises significant concerns about the near-term commercial viability and adoption rate of such robots, potentially impacting investor sentiment towards companies like UBTECH that are heavily invested in this technology.

While the company has recently announced positive developments, including a new consumer robot brand and strategic partnerships, the fundamental concern over operational efficiency and productivity appears to have weighed heavily on the stock during the session.
