Foreign and Institutional Flows
Market sentiment shifted early in the session as the won stabilized against the dollar. Foreign investors, who were massive net sellers on Monday, returned to the KOSPI with a net purchase of approximately 1.2 trillion won, primarily focusing on large-cap semiconductors and batteries. However, the KOSDAQ remained somewhat volatile, with retail investors continuing to exhibit caution following the multiple circuit breakers triggered earlier in the week.
Key Sector Movers and Market Drivers
The primary driver for today’s KOSPI rebound 2026 was the recovery in the semiconductor sector. Samsung Electronics (005930) and SK Hynix (000660), which had both tumbled nearly 10% yesterday, surged back as global demand concerns slightly eased. Additionally, defense stocks saw continued interest due to ongoing geopolitical uncertainties in the Middle East.

Looking Ahead
While today’s recovery is a welcome relief for investors, the market remains on high alert. High oil prices and the possibility of further escalations in global conflict continue to pose risks to the export-heavy Korean economy. Analysts suggest that the 5,500 level for the KOSPI will serve as a crucial psychological support-turned-resistance zone in the coming days.
