Micron (MU<\/a>) and SK Hynix (SKHY<\/a>) stocks sank 5% on Tuesday amid a global sell-off in memory-chip stocks<\/a> that deepened after South Korea’s benchmark KOSPI (^KS11<\/a>) tanked. <\/p>\n

In South Korea, SK Hynix (000660.KS<\/a>) and Samsung Electronics (005930.KS<\/a>) fell 10% and 7%, respectively, extending their losing streaks to five sessions in a row. The two chipmakers account for more than half of the South Korean stock market’s total capitalization. <\/p>\n

The sell-off was a continuation of market reaction<\/a> after Chinese memory maker CXMT (688825.SS<\/a>) announced progress<\/a> on a new memory-cell design engineered to pack more storage into less physical space. <\/p>\n

CXMT aims to introduce a new server memory product built on this architecture by the end of 2026. <\/p>\n

The advance threatens to intensify competition for Samsung, SK Hynix, and US-based Micron, which together account for roughly 90% of the global DRAM market. <\/p>\n

Micron, SK Hynix, and Samsung have been major beneficiaries of the AI trade over the past year amid surging demand for memory and storage chips driven by the global AI data center build-out. All three memory makers reached a $1 trillion valuation over the summer.<\/a> All three stocks have since come off their all-time highs. <\/p>\n

Last week, Samsung reported a preliminary record third quarter<\/a> profit of $80 billion, but the forecast<\/a> did little to lift the rest of the chip sector, <\/p>\n

Micron posted strong quarterly results in September<\/a>. The stock is up roughly 240% year to date. <\/p>\n
