KOSPI breaks 8,000 record then tanks 6.12%, shedding 488 points to 7,493

Index hit 8,046.78 intraday—the first-ever pierce of 8,000—before foreign selling sparked a 488-point rout. Samsung and SK Hynix account for 50% of the gauge's weight, exposing concentration risk as profit-taking accelerated alongside strike fears and a scoreless Trump-Xi Beijing summit.
