South Korea ETF (EWY) has traded in a volatile October range between roughly $148 and $193 amid heavy exposure to memory semiconductors, with Samsung Electronics and SK Hynix comprising nearly 45% of assets. Recent global AI capital-spending concerns and U.S. tech earnings pressure triggered a sharp mid-to-late month selloff, erasing much of the prior recovery and leaving the ETF down about 13-19% over 30 days despite a 67-71% year-to-date gain driven by record chip demand. South Korea’s third-quarter GDP beat forecasts, with semiconductors contributing substantially to growth, while the won’s appreciation and pending ETF index change effective in November add near-term uncertainty to closing levels and trader positioning.
