AI memory and semiconductor stocks fell broadly Friday after steep losses in Asian markets spilled into U.S. trading, pressuring some of the year's strongest technology names.

South Korea's Kospi plunged 5.7%, with SK hynix down about 11% and Samsung (SSNLF) Electronics falling nearly 8%. Japan's Nikkei 225 dropped 2.7% as Kioxia, Tokyo Electron and Advantest posted sharp declines.

The weakness quickly spread to U.S.-listed memory stocks. Micron NASDAQ:MU fell around 6%, while Sandisk NASDAQ:SNDK and SK hynix's ADR each dropped roughly 7%. Western Digital NASDAQ:WDC lost about 5%, and Seagate NASDAQ:STX declined nearly 4%.

Other AI-related stocks also moved lower. AMD NASDAQ:AMD fell nearly 2%, Broadcom dropped about 2%, and Intel NASDAQ:INTC slid almost 4% despite reporting stronger-than-expected results. Networking and optical names, including Coherent, Lumentum and Celestica, suffered even steeper declines.
