South Korea ETF (EWY) experienced sharp intraday swings during the week of October 19, 2026, with prices ranging from lows near $148 to highs around $159 amid heavy weighting in semiconductors. Samsung Electronics and SK Hynix, together comprising over 40% of holdings, drove moves as global AI investment concerns triggered profit-taking and a KOSPI drop exceeding 3% mid-week before a rebound on bargain hunting and news that SK Hynix would suspend its U.S. subsidiary IPO review. Recent trading reflected broader volatility in tech valuations, with the ETF closing October 22 at $149.06 after a 4.98% single-day decline. Key factors include semiconductor margin dynamics, foreign investor flows, and any shifts in U.S. tech capex signals ahead of further earnings or policy updates.
