KOSPI Reaches 8,000 and the Retail Response
The KOSPI index made history in May 2026 by hitting the 8,000-point milestone, drawing global attention. The reaction from retail investors has been intense; according to the English edition of the Seoul Economic Daily, retail investors have continued to bet 34 trillion won on the market even after the 8,000-point threshold was breached.
This shows that retail investors are clearly betting on a market rebound, despite the KOSPI’s sharp 6-7% plunge on May 15 following heavy selling by foreign investors.
Foreign Sell-off and Market Volatility
Back on May 15-16, the KOSPI experienced extreme volatility, briefly pushing past 8,000 before crashing below 7,500 due to foreign sell-offs.
- Foreign investors sold off approximately 5 trillion won (KRW), dragging the index down.
- Automated trading halts (circuit breakers) were triggered during the turbulence.
With this clash between foreign exits and retail bullishness, all eyes are on who will ultimately take control of the market's direction.
The KOSDAQ Lag
While the KOSPI is in the middle of a major bull run, the KOSDAQ has been relatively left behind, with reports showing a trend of companies and investors moving away from the exchange.
