The Korean stock market closed lower on Friday, February 27, 2026, ending a remarkable six-day winning streak that saw the KOSPI index reach multiple record highs. The benchmark KOSPI closed at 6,244.13, down 63.14 points or 1.00%, while the tech-heavy KOSDAQ dropped 1.07% to 1,175.40.
Market Overview: KOSPI and KOSDAQ Performance
KOSPI Ends Six-Day Rally
After reaching an all-time high of 6,307.27 on Wednesday, the KOSPI experienced a modest pullback on Friday. The decline came after six consecutive sessions of gains fueled by strong semiconductor stocks and investor optimism surrounding artificial intelligence technologies. Despite the Friday retreat, the index remains up significantly from the start of 2026, when it first crossed the 4,300 mark.
Trading volume remained active with institutional and foreign investors showing mixed sentiment. While some profit-taking occurred after the record-breaking rally, long-term fundamentals for the Korean technology sector remain strong.
KOSDAQ Follows Bearish Trend
The technology-focused KOSDAQ index mirrored the KOSPI’s decline, closing at 1,175.40 after dropping 1.07%. Small and mid-cap technology companies faced pressure as global tech sentiment weakened following volatility in major US markets.
Semiconductor Sector Drives Market Sentiment
Samsung and SK Hynix Lead Tech Stocks
Despite Friday’s overall market decline, semiconductor giants Samsung Electronics and SK Hynix continue to dominate the Korean stock market landscape. According to Macquarie research, these two companies are expected to account for 52% of total net profits in 2026, and 68% of profit increases across the market.
The memory chip sector remains a key driver, with analysts projecting Samsung Electronics to post an operating profit of 87.1 trillion won in fiscal 2026, while SK Hynix is expected to earn 77.1 trillion won. Both companies have benefited from strong demand for high-bandwidth memory chips used in AI applications.
Global ETF Inflows Surge
A wave of international capital continues to chase Korean semiconductor stocks, creating abnormal trading volumes in exchange-traded funds. According to Bloomberg reports, the US-listed iShares MSCI South Korea ETF saw daily turnover soar to a record high of $6.4 billion on Thursday. Korean chip ETFs have also experienced elevated volumes in Hong Kong and Shanghai markets.
Global Market Impact and Outlook
US Market Volatility Affects Asia
Friday’s decline in Korean markets was partly attributed to overnight weakness in US technology stocks, particularly concerns around Nvidia and other semiconductor companies. Global market interconnection means that volatility in major US tech stocks often ripples through Asian markets, especially those heavily weighted toward technology sectors.
Investors are closely monitoring US Federal Reserve policy signals and economic data that could impact global technology demand. The correlation between US and Korean tech stocks remains high, making global economic indicators crucial for Korean stock market direction.
Investment Opportunities Ahead
Despite the Friday pullback, market analysts remain optimistic about the Korean stock market’s medium-term prospects. Government initiatives aimed at eliminating the “Korea discount” – the persistent undervaluation of Korean stocks compared to global peers – are gaining traction.
