KOSPI Hits New Heights in KOSPI Record High Tech Rally
The South Korean equity market reached a historic milestone on Monday, February 23, 2026, as the benchmark KOSPI index surged to a fresh record high. This KOSPI record high tech rally was fueled primarily by explosive gains in the semiconductor and automotive sectors, as investors brushed off global tariff concerns and focused on the robust earnings outlook for AI-linked technology giants.
The KOSPI finished the day at 5,846.09, marking an increase of 37.56 points or 0.65% from the previous session. The junior KOSDAQ index closed at 1,151.99, adjusting from its intra-day movements. Trading volume was heavy as institutional and retail investors stepped in to support the market’s upward trajectory, even as some foreign investors took the opportunity to lock in profits after a multi-day winning streak.
Market Summary and Key Indices

Semiconductor Giants Lead the Charge
The primary driver of today’s KOSPI record high tech rally was the performance of market heavyweights Samsung Electronics and SK Hynix. As the global demand for high-bandwidth memory (HBM) continues to outpace supply, analysts remain bullish on the long-term prospects of Korea’s semiconductor export powerhouses. Samsung Electronics (005930) rose 2.15%, while SK Hynix (000660) jumped a significant 3.42%, continuing its trend of outperforming the broader market.
The automotive sector also contributed to the gains, with Hyundai Motor (005380) and Kia (000270) seeing increases of 1.8% and 2.1% respectively. Positive export data for February has bolstered confidence in the sector, despite ongoing discussions regarding international trade policies. Investors are closely monitoring how these companies adapt to the shifting global landscape, as discussed in our previous report on Korean auto export trends.
Top Individual Stock Movers
- SK Hynix (000660): +3.42% — Leading the AI memory chip surge.
- Samsung Electronics (005930): +2.15% — Broad-based tech recovery support.
- Hyundai Motor (005380): +1.80% — Strong export performance in EVs.
- LG Energy Solution (373220): -0.45% — Slight pull-back amid battery material price volatility.
- POSCO Holdings (005490): +1.20% — Rebound in industrial commodity sentiment.
Foreign Investor Flows and Market Sentiment
Interestingly, while the market indices climbed, data indicated that foreign investors were net sellers for the session. According to preliminary data from the Korea Exchange (KRX), foreign investors offloaded approximately 215 billion won worth of shares, likely locking in gains after the KOSPI broke through the 5,800-point psychological barrier last Friday. However, this selling pressure was more than offset by institutional buying and a surge in retail participation, which collectively drove the index to its new closing record.
Market analysts suggest that the “Korea Discount” is rapidly narrowing as corporate value-up programs and improved transparency begin to attract more long-term domestic capital. The resilience of the Seoul market against global headwinds suggests a shift in sentiment toward South Korea as a stable growth hub in the Asia-Pacific region.
Looking Ahead
As the KOSPI enters uncharted territory, investors will be watching for potential consolidation. However, with the tech sector showing no signs of slowing down, the momentum remains strong. Key economic indicators to watch later this week include the BOK interest rate decision and industrial production figures.
