KOSPI triggered a circuit breaker on June 8, 2026, as Korean equities plunged 6.5%. NAVER's AI Factory roadmap was the lone bright spot amid forced deleveraging.
KOSPI hit a circuit breaker (-6.5%) as foreign and institutional selling dominated. 4-screener name Jeju Semiconductor leads quality re-rating candidates.
May 2026 U.S. CPI can print a hot headline because of energy and the low May 2025 base. But the investment event is core CPI MoM. The probability-weighted center is +0.26%, the chance of +0.30% or lower is 75%, and the hot-print tail above +0.35% is 13%.

For Korean equities, the key is not prediction but discipline: watch U.S. 10-year yields, CPI, foreign futures flows, KOSPI 8,000, and Samsung Electronics / SK Hynix relative strength.
After the strong U.S. May employment report, the key macro cluster is May CPI on June 10, Korea's derivatives expiry on June 11, the BOJ on June 15-16 and the FOMC on June 16-17.
