SK Hynix shares fell 6% following a five-day selloff in Seoul sparked by ChangXin Memory Technologies' announcement of a new memory-cell design with higher capacity. This news also caused Western Digital and Seagate shares to drop 7%, despite their focus on hard drives rather than memory chips. The selloff reflects investor concerns over competition and AI spending sustainability in the chip sector. The market will closely watch CXMT's planned year-end server memory launch to gauge the impact on memory and storage stocks.
