KOSPI Record Masks a Two-Stock Concentration Risk | June 23, 2026 [boPg50p6U9k]
The KOSPI hit 9,114 on Monday. Take out Samsung Electronics and SK Hynix, and the market fell 2.48% this month. In today's AI PRISM: Stock Investors, we break down Korea's sharpest market divergence of 2026: a KOSPI at all-time highs driven almost entirely by two semiconductor names. Foreign investors net-sold 2.55 trillion won, roughly 1.8 billion U.S. dollars, on the same record-setting day. Short-selling overheat designations have already exceeded all of last year's total, with outstanding loan balances up 66.8% year-to-date to 188.6 trillion won. And Korean retail demand for 3x leverage in SK Hynix — unavailable domestically — drove a London-listed ETP to grow 12-fold in five trading days.
