Global AI chip stocks slide as SK Hynix and Samsung drop over 12% and SOXX falls more than 7%

AI chip stocks saw heavy selling globally, with South Korea’s SK Hynix and Samsung Electronics falling more than 12% in a single session, triggering forced liquidations and a wave of leveraged ETF selling. U.S. semiconductors also sank, with the SOXX ETF down more than 7% and SanDisk down more than 12%, Micron off more than 11%, and ARM down more than 7%. A strong U.S. manufacturing PMI print failed to lift sentiment. Markets are focusing on whether AI-related asset valuations can remain sustainable.
