51WORLD's stock plummeted 9.07% during intraday trading on Wednesday, marking a significant pullback after the stock's extraordinary rally in recent sessions.

The decline comes as multiple analysts had flagged elevated pullback risks following the stock's rapid ascent, which saw cumulative gains exceeding 100% over the prior week. Valuation concerns emerged with the company's price-to-book ratio near 50x and negative earnings per share, prompting warnings that the stock had already priced in significant short-term expectations at current levels.

Investment analysis noted that if subsequent business growth falls short of expectations, a phased valuation correction could occur. The stock had previously surged on Physical AI tailwinds, including the launch of 51World Model and Aperdata.ai platform, but analysts cautioned that the pace of gains was unsustainable and correction risk was material.
