KOSPI recorded its largest-ever crash (down 9.99% on the 23rd) as extreme concentration in Samsung Electronics and SK hynix, combined with leverage liquidation and foreign selling, brought down the entire market. The cause was a triple whammy of AI investment overheating and rate hike concerns.
Bullish tone rose steadily from 06-18 to 06-22 in the 7-day window, then reversed sharply on 06-23, with bearish narratives exploding today (06-24). Appeared across all 7 days.
