Shangwei New Materials Stock Doubles in 18 Sessions, Warns on Robot Revenue
On the evening of Nov. 9, Shangwei New Materials (SH688585) disclosed that its shares had risen more than 100% over the prior 18 trading sessions. The stock was quoted at 216.02 yuan, giving the company a market value of 87.1 billion yuan, while its latest price-to-earnings ratio reached 1,767.36x.
The company flagged short-term overheating risk and urged investors to watch trading volatility after the rapid gains. It linked the rally to heightened secondary-market interest in humanoid robot concepts, a theme that has drawn strong speculative attention.
Shangwei also stressed that its consumer-grade embodied intelligent robot business is still at an early stage and accounts for a low share of revenue. It warned that this limited contribution may not significantly support overall performance, highlighting the risk tied to its robot business.
The announcement underscores how concept-driven rallies can outpace fundamentals, even as companies disclose early-stage commercialization and limited revenue visibility.
