KOSPI
The index retreated to the 5,380 level, triggering a program sell-order halt (sidecar), as heavy foreign selling concentrated in large-cap semiconductor stocks exerted severe downward pressure.
Headline
Briefing: Domestic Markets Plunge Amid U.S. Midterm Aftermath and AI Regulatory Concerns
Key Takeaways
- Concerns over potential AI data center regulations following U.S. midterm election results triggered sell-sidecars on both the KOSPI (-5.28%) and KOSDAQ (-5.11%), causing both benchmarks to plunge.
- Although the Nasdaq climbed 1.44% on the back of megacap tech gains, pullbacks across semiconductor names, including Micron (-7.0%), pressured the South Korean market.
- Heavy foreign net selling concentrated in large-cap chipmakers, including Samsung Electronics and SK Hynix, amplifying broader market volatility.
KOSDAQ
A sell-sidecar was also triggered in the afternoon due to steep declines in the KOSDAQ 150 futures and spot index, sharply cooling sentiment across tech growth stocks.
NASDAQ
While the index advanced 1.44%, clear divergence emerged between software/platform megacaps and semiconductor/hardware supply chain equities.
Today's Watchlist
- Specific regulatory proposals for AI infrastructure and semiconductors reflecting the incoming U.S. Congress policy direction
- Whether foreign capital flows stabilize and net selling abates following the sell-sidecars on the KOSPI and KOSDAQ
- FX-related loss pressures tied to KRW/USD exchange rate stability around the 1,340 level and global bond yield volatility
Risk Note
While technical rebound potential following sharp short-term declines may be raised, attention is warranted regarding downside risks stemming from policy uncertainty and shifts in semiconductor demand projections.
