South Korea's Kospi Slides 20% in July as Banks See Semiconductor Selloff Nearing End

3 articles · Updated · CNBC · Jul 21

Summary

  • A roughly 20% July drop has put South Korea's Kospi on track for its worst monthly loss since 2008, after a profit-taking and deleveraging wave hit semiconductor-linked shares.
  • JPMorgan said the unwind in single-stock leveraged ETFs is about three-fourths complete and kept an overweight view on Korea, signaling the pullback may be close to ending.
  • TS Lombard called the slump a semiconductor deleveraging event rather than a broader bust, while Bank of America said selling pressure may be fading after broader stocks underperformed large caps for the first time since March.
  • The retreat has been painful for retail investors in leveraged ETFs, but the Kospi is still up about 60% in 2026 after gaining more than 75% last year.
  • Investors watch Korea closely because its heavy exposure to memory-chip stocks can make the market an early signal for U.S. equities tied to the AI infrastructure boom.
