What happened: SK Hynix shares extended a sell-off, falling another 11% as investors retreated from the semiconductor trade amid Chinese competition, tight NAND supply, and doubts about AI infrastructure spending. Key numbers: SK Hynix fell 11% Thursday and 31% over seven sessions, down 58% from its summer peak but still up 93%.
