KOSPI Surpasses 2,750 as Samsung Electronics Hits Record High: What's Driving Market Polarization?
KOSPI surpasses 2,750 as Samsung Electronics hits record high amid strong foreign buying, driving market polarization focused on AI semiconductors.

The KOSPI has powerfully broken through the 2,750 mark, driven by massive net buying from foreign and institutional investors. Leading the rally, Samsung Electronics hit a record high based on closing prices since its stock split. However, this surge has created an extreme market polarization, with the tech-heavy KOSDAQ index closing lower as capital heavily concentrates on large-cap stocks.
Samsung's Record High and the Nvidia Halo Effect
The primary driver behind this KOSPI surge is the 'Nvidia halo effect,' moving in tandem with the global AI semiconductor rally. Anticipation surrounding Nvidia CEO Jensen Huang's expected visit to South Korea has triggered a strong influx of buy orders into major domestic semiconductor stocks tied to the AI value chain. Conversely, this aggressive shift of market funds into premium large caps has left the KOSDAQ market—largely composed of small and mid-cap stocks—facing a supply-demand vacuum and subsequent weakness. Compounding the situation, heightened geopolitical tensions pushed the won-dollar exchange rate into the 1,380 won range during intraday trading, further increasing overall market volatility.
Key Investor FAQ
- Q: Is there room for further upward momentum after KOSPI's 2,750 breakthrough?
A: Expectations for earnings improvement centered on large caps remain valid, supported by the structural growth of explosive AI semiconductor demand. However, investors must consider the possibility of short-term profit-taking driven by the rising won-dollar exchange rate and extreme market concentration. - Q: How long will the weakness in the KOSDAQ market persist?
A: A short-term rebound may be difficult as the market's leading theme is heavily skewed toward 'large-cap semiconductors.' A flow of funds into KOSDAQ small and mid-caps can be expected when the leading stocks' upward momentum slows and sector rotation begins.
