Memory chip stocks fall as Seoul selloff raises doubts on AI spending sustainability

Memory chip stocks including SK Hynix, SanDisk, and Micron fell sharply after a selloff in Seoul revived concerns about the sustainability of AI-driven spending in data centers. SK Hynix dropped 4%, SanDisk 3%, and Micron 2%, reflecting worries that the AI spending boom may be peaking. The upcoming SK Hynix earnings report is seen as a key indicator of whether AI memory demand will hold up amid these fears. Investors are advised to remain cautious and moderate their positions until more clarity emerges from the report.

SK Hynix trades at USD 138.95 on Pluang, down 2.74% as of Oct 20, 2026 20:41 WIB. SanDisk is priced at USD 1,345.61 with a 1.82% drop, while Micron stands at USD 886.50, down 2.03%. Pluang order activity shows more buyers than sellers for these stocks, indicating some investor interest despite recent declines.
