On July 7, iShares MSCI South Korea ETF (EWY) declined 5.06% overnight, trading at $179.8/share, with turnover of $60.52 million.

On the news front, South Korea's KOSPI index plunged over 5%, prompting the Korea Exchange to activate its circuit breaker mechanism after KOSPI 200 futures fell 5%, halting programmatic trading for five minutes. Samsung Electronics dropped as much as 8% despite reporting blockbuster Q2 preliminary results — operating profit of 89.4 trillion won, surging 1,810% year-over-year and exceeding the consensus estimate of 84.2 trillion won.

Analysts attributed the selloff to a classic sell-the-news dynamic. Samsung's stock had already rallied over 158% in the preceding 18 months, with the super-cycle earnings fully priced in. Industry observers noted that capital is rotating from memory chip producers toward upstream equipment makers, as Samsung and SK Hynix recently announced massive AI-related capex plans. Structural concerns around Korea's leveraged single-stock ETFs — now totaling approximately $45 billion — further amplified market volatility.

The fund generally invests at least 80% of its assets in the component securities of the MSCI Korea 25/50 Index, a free float-adjusted market capitalization-weighted index designed to measure large- and mid-cap equity performance in Korea.
