Today's Market Briefing — 2026-06-01
Key Market Highlights

1. KOSPI surpasses 8,000 and hits a new record By the end of May, the KOSPI hit an all-time high, breaking past the 8,000 level. While institutional buying and hopes for a US-Iran truce pushed the market up, the rally is becoming increasingly lopsided, relying heavily on a small group of large-cap stocks like Samsung Electronics and SK Hynix.

2. Divergence in semiconductor trading As of May 29, trading volume has been dominated by semiconductor stocks like SK Hynix, Samsung Electronics, and Samsung Electro-Mechanics. The strong performance in the memory semiconductor sector continues, with market momentum driven by expectations surrounding AI data centers and Energy Storage Systems (ESS).
3. High volatility evidenced by 6 sidecar triggers in May The KOSPI saw its "sidecar" (temporary trading halt for program orders) triggered six times in May. Even with the optimism driving prices up, the sharp short-term volatility means investors need to stay cautious.
