Weekly Recap: KOSPI Navigates Global AI Volatility and Export Resilience (Feb 9–13, 2026)

The South Korean stock market experienced a dynamic week as the KOSPI index grappled with shifting global sentiments regarding AI valuations and domestic economic signals. Despite mid-week volatility triggered by Wall Street’s tech correction, the KOSPI showed remarkable resilience, finishing the week near the 5,500 level.

KOSPI Market Performance: Tech Giants Lead the Charge

Early in the week, the KOSPI surged, reclaimed key psychological levels driven by a significant rally in semiconductor stocks. Samsung Electronics and SK Hynix remained the central pillars of market movement, reflecting global demand for HBM and advanced foundry solutions.

• SK Hynix (000660): Continued its strong momentum, spiking 3.26% on Friday as investors bet on integrated AI solutions and upcoming HBM4 supply schedules.
• Samsung Electronics (005930): While showing some intraday volatility (-0.54% mid-week), it held steady above key support levels, supported by long-term growth prospects in its semiconductor division.

The KOSPI closed Friday’s session around 5,507.01, reflecting a slight 0.3% retreat as investors engaged in profit-taking after the recent rapid ascent.

Macro Indicators: Export Data and Global Inflation

South Korea’s macro landscape presented a “policy bind” this week. Export data continues to show strength in the tech sector, yet domestic GDP concerns linger. Key highlights include:

• AI Volatility Impact: Global markets are increasingly hunting for “AI losers,” leading to sharp rotations out of over-leveraged tech names. K-tech stocks, however, are viewed as essential infrastructure providers, mitigating the impact of this rotation.
• Currency and Inflation: US CPI data remains a shadow over the Bank of Korea’s interest rate path. A persistently weak Won continues to favor exporters but adds pressure on domestic consumption and import costs.

Sector Spotlight: Chemicals and Finance

Beyond semiconductors, other sectors saw notable movement:

• Energy and Battery: LG Chem and Samsung SDI saw gains of 4.34% and 2.25% respectively, benefiting from renewed interest in the EV supply chain stability.
• Finance: Financial holdings, including Shinhan Financial, showed strength as the “Corporate Value-up Program” continues to incentivize better shareholder returns.

Conclusion: Looking Ahead

The Korean market is transitioning from a broad rally to a more selective “quality-driven” phase. Investors should monitor the upcoming export figures for February and the Federal Reserve’s tone on inflation.
