NVIDIA's stock reached an all-time high during intraday trading on Thursday, driven by strong demand for AI chips in China. The stock rose 3.7% to $234.18, marking a year-to-date increase of over 25%. This surge is fueled by reports that major Chinese tech companies, including Alibaba, Tencent, ByteDance, and JD.com, are preparing to purchase NVIDIA's H200 AI processors, pending regulatory approval. The Philadelphia Semiconductor Index also hit a record high, with other chip stocks like Broadcom and TSMC rising in tandem, reflecting investor focus on AI infrastructure. As NVIDIA's earnings report approaches on May 20, investors are keenly watching for updates on the company's progress in China, especially given the slow regulatory approval process and ongoing U.S.-China trade tensions. Despite high expectations, potential volatility remains if earnings do not significantly exceed market estimates.
