Zhito Finance APP has learned that on Monday, chip stocks fell broadly, with Qualcomm (QCOM.US) dropping nearly 7%, SanDisk (SNDK.US) falling over 5%, SK Hynix (SKHY.US) down 5%, and Intel (INTC.US) and Western Digital (WDC.US) declining more than 4%. Seagate Technology (STX.US), Advanced Micro Devices (AMD.US), and Micron Technology (MU.US) each fell over 3%. On the news front, OpenAI suddenly suspended the training and testing of its most advanced AI model, raising market concerns that a slowdown in AI development could weigh on chip demand; meanwhile, surging oil prices and rising U.S. Treasury yields further amplified the selling pressure on tech stocks.
