KOSPI Plunges as Foreigners Sell: Market Briefing 2026-06-07
The Korean market faced a massive sell-off on Friday, June 5, 2026, driven by intense foreign selling and a slump in U.S. semiconductor stocks. The KOSPI plummeted over 5%, hovering near the 8,000-point level, while the KOSDAQ fell below 1,000 for the first time in three months. Foreign investors net-sold 4.3 trillion won in KOSPI stocks, fueling the downturn.
Domestic Stock Market Briefing — 2026-06-07
Market Index Overview
| Index | Closing Price | Change | Percent Change | Notes |
|---|---|---|---|---|
| KOSPI | ~8,070–8,100 | -450~-480 | -5.3~-5.6% | Heavy foreign sell-off, led by tech weakness |
| KOSDAQ | ~1,002 | -47 | -4.5% | Dropped below 1,000 for first time in 3 months |
On Friday, June 5, the Korean stock market suffered heavy losses due to a combination of large-scale foreign selling and global semiconductor weakness. The KOSPI slid by over 5%, and the KOSDAQ hit 992.80, breaking the 1,000-point threshold for the first time in three months. Although the KOSPI touched the 8,000 mark during the day and saw a slight recovery, it failed to break free from the bearish trend. Foreigners dumped 4.3 trillion won in KOSPI equities, becoming the primary catalyst for the decline.
Supply and Demand by Investor Type
- Foreigners: Net-sold 4.3 trillion won, serving as the main driver of the market decline. The selling trend, which has persisted for several weeks, intensified on Friday, putting a massive strain on local liquidity. Coupled with global semiconductor weakness, this has accelerated corrections for tech-heavy stocks.

Major Movers
Top Decliners (Semiconductor & Tech Focus)
Semiconductor Stocks (Samsung Electronics, SK Hynix, etc.): These shares took a major hit, tracking the slump in AI-related stocks on the U.S. Nasdaq. Concerns over poor earnings due to a weakening global semiconductor cycle have intensified selling pressure.
Sector Performance
Weakest Sectors
- Semiconductors & Electronics: The primary factor in the KOSPI's drop. Large-cap stocks fell sharply in sync with the global market following a pause in the U.S. AI rally.
- IT & Communications: Widespread correction across the tech sector.
Key Issues & Drivers
4.3 Trillion Won Foreign Sell-off… A "Black Friday"
- Context: The KOSPI's 5%+ plunge was led by a massive 4.3 trillion won sell-off by foreigners. This culminates weeks of heavy selling. As global capital pivots—amid events like the SpaceX IPO—liquidity in the Korean market is drying up.
- Impact: Triggered a broad correction in tech and large-cap stocks. Rising KRW/USD exchange rates (near a 17-year high) have further fueled the desire to realize currency gains.
U.S. AI Rally Stalls… Nasdaq Tech Slump
- Context: Weakness in AI-related stocks (especially semiconductors) on the Nasdaq has spread globally. Wall Street's sell-off of semiconductor holdings has hit local giants like Samsung Electronics and SK Hynix.
- Impact: Broad correction for KOSPI tech stocks, dampening medium-term profit expectations.
KOSDAQ Sinks Below 1,000… First Crisis in 3 Months
- Context: The growth-heavy KOSDAQ dropped to 992.80 during intraday trading. The combination of foreign selling and tech weakness caused a simultaneous slide in small-cap and venture stocks.
- Impact: Fears of stop-loss selling among small-to-mid-cap investors are growing, souring overall sentiment.
Macro Factors
- Exchange Rate (KRW/USD): Approaching a 17-year high, incentivizing foreigners to pull capital out to realize currency gains.
- U.S. Semiconductor Weakness: Spillover effect from the Nasdaq’s AI-related decline signals weakening global supply and demand.
- Global Liquidity Reallocation: Capital flight from emerging markets as investors shift focus to global mega-tech IPOs like SpaceX.
Tomorrow’s Checkpoints
- Monitor the strength of foreign net selling following Friday's session.
- Watch for any potential recovery of the KOSDAQ's 1,000-point level.
- Observe the performance of semiconductor stocks on the U.S. market.
Investor Guidance
- Short-term: Expect the broad correction to continue. Pressure to cut losses on tech and foreign-held stocks remains high. Avoid bottom-fishing until the downward momentum stabilizes.
- Medium-to-long-term: Sustained foreign selling suggests a structural weakness in the domestic market. Consider reducing weight in tech until the semiconductor cycle shows signs of recovery.
- Risk Factors: (1) Continued foreign selling, (2) Further decline in U.S. semiconductors, (3) Additional spikes in the KRW/USD exchange rate.
Expert Commentary
While real-time brokerage reports are limited, local media outlets like Edaily and Maeil Business Newspaper note that "the market's sentiment has soured rapidly due to the dual blow of massive foreign selling and global semiconductor weakness." Analysts suggest waiting for clear signals that the semiconductor cycle has turned.
