South Korea's stock market was halted after the KOSPI fell 8.5% within three minutes of the open, with memory giants in freefall: SK Hynix down 12% and Samsung down 10% — Korean media dubbed it a "blue tsunami." Charts show staggering drawdowns from mid-year peaks: SK Hynix fell from 2.96M to 1.22M KRW, a 61.77% drop (still +64.84% YTD), while Samsung slid from 367,180 to 184,660, down 49.68%. As the core HBM suppliers to the AI compute supply chain, both stocks had hit all-time highs just months ago, and the crash signals mounting market anxiety over an AI compute bubble.
