Why is SK Hynix stock sliding today?

SK Hynix shares dropped 7.2% to 296,000 won on Thursday due to a broader sell-off in South Korean semiconductor stocks. The decline was driven by concerns over U.S. AI regulations and delayed chip equipment export licenses for China. Weak earnings from Arm and Qualcomm also contributed to the downturn. Investors sold off AI-exposed chipmakers, including SK Hynix, on fears of reduced demand for high-bandwidth memory.
