South Korea’s EWY, which tracks the MSCI Korea Index with roughly 55% technology exposure led by Samsung Electronics and SK Hynix, traded in a volatile range during the week of September 14, 2026, closing the prior session near 182.39 before dipping intraday. The ETF’s performance remains tightly linked to memory-chip demand for AI infrastructure, where both firms now represent over half of KOSPI market capitalization. Recent pressure stems from higher global bond yields, Bank of Korea rate hikes, a stronger won, and oil prices above $100, which have weighed on earnings multiples and prompted negative EPS revisions. Leveraged ETF unwinding and retail sentiment shifts have amplified daily swings, with the 52-week high near 221 reached in June still well above current levels around 180. Key near-term catalysts include upcoming Q3 earnings and any further central-bank signals on monetary policy.
