KOSPI, 8% Plunge and Market Recovery Efforts
The KOSPI is seeing a partial recovery following yesterday’s 8% drop, though heavy selling in semiconductor giants like Samsung Electronics and SK Hynix persists as foreign investors continue to exit. Weakness in the Philadelphia Semiconductor Index and Fed rate hike concerns have fueled this tech-led slump. Tomorrow’s Asian market session is expected to face pressure from weak U.S. futures and a softer Korean won.

KOSPI
- Closing Price: Rebounded to the 7,600 level (after an 8.23% drop yesterday)
- Intraday Movement: Below 7,500 → Recovered to the 7,600 level
- Trading Halt: Circuit breaker triggered during the morning session due to a 7.5% decline, halting trade for 20 minutes
- Key Drivers: Philadelphia Semiconductor Index drop of over 10%, rising Fed rate hike concerns, and heavy foreign selling
KOSDAQ
- Closing Price: Partial recovery after a drop of over 8%
- Characteristics: Triggered the same circuit breaker as the KOSPI
- Leading Sectors: Small-cap semiconductors and tech stocks saw the sharpest declines
Top Korean Market Movers (June 8-9)
Gainers — 3 or more
- SK Hynix (Approx. 2.038 million won, recovered from intraday lows): Attempting a partial rebound after an intraday drop of over 8%, looking to recover technical support levels despite weak memory prices.
- Samsung Electronics: Reduced losses to about 8% after an intraday drop of 10%.
Decliners — 3 or more
- Samsung Electronics (-Approx. 10%, intraday peak): Faced the largest drop due to weakness in the Philadelphia Semiconductor Index and massive foreign outflows.
- SK Hynix (-Approx. 8-10%, intraday): Ongoing DRAM weakness and foreign selling pressure.
- Numerous Mid-cap Semiconductor Stocks (-5% or more): Surge in losses for affected companies; heavy losses for investors in single-stock leveraged ETFs.
Sector Trends
- Semiconductors & Memory: Philadelphia Semiconductor Index plunged over 10%, while Samsung Electronics and SK Hynix fell near 10%. Foreign investors are exiting en masse amid concerns over the AI rally, signaling prolonged global chipset weakness.
- Other Tech Stocks: KOSDAQ-wide weakness has deepened.
- Defense Industry: Stocks are trading relatively flat to lower following the stabilization of Middle East tensions (end of Iran-Israel missile attacks) and a subsequent dip in oil prices.
Key Factors Driving the Global Market
- Philadelphia Semiconductor Index drops 10%+ (June 7 U.S. session): Declines in chipmakers like Broadcom sparked concerns that AI memory demand may be overvalued, providing a direct trigger for the sell-off in Korean semiconductor export stocks.
- Strong U.S. May Jobs Data: Higher-than-expected job growth increased the likelihood of Fed rate hikes, leading to higher 10-year U.S. Treasury yields and a flight to safety.
- Partial Recovery in U.S. Nasdaq & S&P 500 (June 8): The U.S. market turned positive, led by chips, and oil prices remained stable following the de-escalation in the Middle East.
Asian Market Outlook
Despite a partial recovery in chips during the U.S. session, the Korean KOSPI remains in a state of structural weakness. Continued foreign investor outflows and a weakening Korean won are expected. Upon the opening of the Asian market, the KOSPI may face limited upside due to signs of weak U.S. futures and a rising KRW/USD exchange rate (estimated to be above the 1,200 won level). While Samsung Electronics ADR and SK Hynix ADR may find some technical support from the U.S. chip rebound, fundamental weakness is likely to persist.
Upcoming Issues to Watch
- Economic Announcements: Korea's May CPI (due later this week), early June U.S. economic indicators.
- Corporate Earnings: Reassessment of guidance for semiconductor companies and continued earnings reports from domestic large-cap firms.
- Technical Support: Whether the KOSPI holds the 7,500 support level and Samsung Electronics holds the 70,000 won level.
- Macro Variables: Changes in Fed policy expectations, KRW/USD exchange rate (concerns over 1,200 won), and oil prices (risks of re-escalating Middle East tensions).
Investor Action Items
- Korean Retail Investors: Instead of simply selling semiconductor giants (Samsung Electronics, SK Hynix), consider entering only after confirming technical support. Investors in single-stock leveraged ETFs should prioritize preventing further losses.
- Global Investors with Korea Exposure: Keep an eye on KRW exchange rates, considering the rising cost of currency hedging. Monitor non-semiconductor large-caps like KB Financial and POSCO for their relative value.
- Macro Response: Consider adjusting the weight of safe-haven assets in preparation for a Fed rate hike scenario. Preemptively prepare for the possibility of broad-based weakness in Asian tech stocks.
