Memory stocks sold off sharply in the week of October 12, CNBC reported. Over five days SK Hynix fell 26%, Samsung 22% and Micron about 11%. The selling began after China's ChangXin Memory Technologies, CXMT, announced plans for a server memory product based on a new architecture, raising concern it could take share from Samsung, SK Hynix and Micron. A column in a South Korean paper also suggested memory oversupply in 2029.
Analysts called the move sentiment-driven rather than a change in high-bandwidth memory demand, with one saying the Korean chipmakers still dominate HBM. Earlier this year SK Group chairman Chey Tae-won said the global memory shortage could stretch toward the end of the decade.
