KOSPI
Earnings revision expectations for AI semiconductor supply-chain leaders, including Samsung Electronics and SK Hynix, continue to bolster the index floor; however, potential profit-taking pressures near the 7,100 level warrant caution.
Headline
Global & Domestic Market Daily Briefing - September 25, 2026
Key Takeaways
- The KOSPI gained 0.90% to close at 7,080.92, firmly holding above the 7,000 mark driven by institutional and foreign buying in large-cap semiconductors.
- The Nasdaq rallied 1.97% to 26,939.37 amid tech strength, while the USD/KRW exchange rate climbed 0.83% to settle at 1,366.70 KRW.
- Divergence across sectors widened due to wait-and-see sentiment ahead of the Chuseok holiday and key U.S. macroeconomic releases.
KOSDAQ
The index advanced 1.21% to 844.48 on positive spillovers into tech shares, yet net liquidity continuity remains narrower than large caps, pointing to a selective strategy centered on names with idiosyncratic catalysts.
NASDAQ
Momentum in Big Tech and semiconductor equities sustained solid upward thrust in the upper 26,000s, though prospective short-term volatility stemming from interest rate swings and valuation multiples should be monitored.
Today's Watchlist

- Whether the USD/KRW stabilizes in the upper 1,360s and the subsequent trajectory of foreign portfolio flows
- Pre- and post-holiday Big Tech earnings previews alongside capital flow sustainability into the AI value chain
Risk Note
A rebound in the foreign exchange rate could trigger foreign profit-taking, and valuation overhead in recently outperforming tech equities may amplify volatility, suggesting a staged, disciplined approach.
