SK Hynix shares tumble 9% amid AI investment concerns sparking Asian tech sell‑off

On October 13, 2026, SK Hynix’s stock fell 9% as investors grew wary of slowing AI‑related spending and heightened memory‑chip competition. The drop dragged down other Asian tech names, with SoftBank losing 8% and Samsung Electronics 6%. Micron Technology also slipped 3.9% earlier in the session.
