Investors sold semiconductor stocks after reported progress by China’s CXMT raised concerns about competition and the outlook for AI spending.
Semiconductor shares fell Tuesday after Chinese memory maker ChangXin Memory Technologies (CXMT) reported progress on a new chip design. The news raised concerns about competition and pricing pressure for Samsung Electronics, SK Hynix and Micron.
South Korea’s KOSPI dropped 5.5%, while SK Hynix shares fell more than 10% and Samsung declined 7.4%. The volatility triggered a temporary trading halt in the South Korean market.
CXMT’s reported design could improve memory density, but the source said commercial success would depend on scaling production and securing reliable yields. The selloff also reflected investor concerns about high AI-related valuations and whether spending will generate sustainable returns.
