Korean Stocks Swing Wildly: Do You Hold Hynix or Samsung?
South Korea's KOSPI delivered an extreme rollercoaster this week — plunging 8.3% to trigger a circuit breaker Monday, rebounding 8.2% Tuesday, then falling as much as 3.6% again Wednesday as chip stocks extended losses.
Samsung Electronics and SK Hynix, which together account for over half the index's market cap, drove the swings. The KOSPI 200 volatility index broke 90 for the first time on record Tuesday, with leveraged ETFs and retail margin trading amplifying daily moves. Could this turmoil be a preview of what's coming for U.S. chip stocks?
