South Korea's iShares MSCI South Korea ETF (EWY) trades near $180 amid elevated volatility, with its price path tied primarily to the AI memory supercycle. SK Hynix and Samsung Electronics, which dominate holdings and over 50% of KOSPI market cap, continue to capture outsized earnings growth from high-bandwidth memory demand tied to hyperscaler AI capital expenditures. August semiconductor exports hit a record $46.65 billion, up 209% year-over-year, supporting the KOSPI near 6,836 despite foreign and institutional selling. Corporate Value-Up reforms, share buybacks, and a weaker won provide additional tailwinds, while high retail leverage and external factors such as U.S. Treasury yields and geopolitical tensions introduce downside risk. Traders monitor near-term export figures, memory pricing trends, and Bank of Korea policy for resolution signals in September.
