51WORLD's stock price plummeted 5.06% intraday on Monday, extending losses from the morning session. The digital twin technology company's shares came under heavy selling pressure as investors reacted to its latest financial results.

The decline follows the company's report showing its attributable loss for 2025 widened substantially to 181.8 million yuan from 79.1 million yuan in the prior year. While revenue grew to 347.8 million yuan from 287.4 million yuan, cost of sales surged dramatically from 140 million yuan to 244 million yuan, compressing gross margin from 51.1% to 30.0%. Increased R&D spending further contributed to the deteriorating bottom line.

Market analysts suggest the sell-off represents continued profit-taking following a significant short-term rally driven by earlier positive catalysts, including analyst coverage initiation and strategic partnerships. Valuation concerns also persist, with the stock trading at an elevated price-to-book ratio well above industry norms.
