Daily Pulse: June 11, 2026

KOSPI 7,424.09 (−3.97%) · KOSDAQ −1.0% · KRW/USD ~1,531

The Tape

Korean equities extended their post-record correction on Wednesday, with the KOSPI declining 3.97% to close at 7,424.09, the fourth losing session in the past five trading days. The index has now retraced more than 15% from its all-time high of 8,933 reached just over a week ago.

What Drove It

Three forces are colliding simultaneously. First, continued foreign institutional selling, overseas investors have now net sold over KRW 5 trillion (~$3.3B) in KOSPI-listed shares since the June 2 peak. Second, retail margin call mechanics: leveraged domestic retail positions accumulated during the January, May rally are being unwound. Third, the macro backdrop: US May CPI data is being pre-traded as a hawkish surprise, pushing 10-year UST yields toward levels that pressure EM equity multiples.

Semis: The Epicenter

Samsung Electronics and SK Hynix, together representing roughly 40% of KOSPI market cap, are down 20 to 25% from their early-June highs. This is a valuation reset, not a fundamental repricing. HBM4 demand from hyperscalers remains robust and TSMC's May revenue confirmed 30% YoY growth.

Levels to Watch

The 7,400 level represents support at the 50-day moving average. A decisive close below opens a move toward 7,000 to 7,200, where KOSPI forward P/E compresses to ~6.5x. Resistance on any bounce sits at 7,750 to 7,800.

One Signal Worth Watching

Citi's warning of "asymmetric downside risk due to elevated bullish positioning" came after a 15% drawdown, suggesting institutional sentiment is still catching down to price action. When the last bull capitulates, the floor tends not to be far away.
