KOSPI Posts Largest-Ever Decline as Chip Concentration Backfires: The KOSPI closed at 8,203.84, plunging 910.71 points (9.99%) from the previous trading day, marking its largest-ever decline. Analysts said the extreme concentration, with the top four semiconductor stocks accounting for 61.7% of the KOSPI, amplified the correction. Securities analysts diagnosed the move as a technical breather rather than a trend reversal.
