Highlights

KOSPI

Currently closed for the weekend as of 2026-10-31. On the last trading day of 2026-10-30, it closed at 5,730.74 (-3.48%); whether the 5,700 level holds remains the key focus amid foreign selling centered on large-cap semiconductor and tech shares.

Highlights

KOSDAQ

Currently closed for the weekend as of 2026-10-31. It closed lower at 724.38 (-3.83%) on the last trading day of 2026-10-30, and stabilization of fund flows is needed following heightened short-term volatility in growth and small-to-mid tech stocks.

Highlights

NASDAQ

Plunged to close at 25,437.00 (-2.86%) on the last trading day of 2026-10-30. Heightened earnings caution regarding major Big Tech names such as Alphabet and Intel, along with debates over AI Capex monetization, fueled downside pressure.

Today's Watchlist
  • Comments and signals regarding potential further tightening and future rate paths following the US Federal Reserve FOMC meeting
  • Final earnings releases and revisions to 2027 guidance from Big Tech and major domestic semiconductor/battery firms
  • Trends in the KRW/USD exchange rate (1,335.80 KRW as of the last trading day) and whether foreign investors switch to net buyers on KOSPI
Risk Note

Volatility across tech equities is rising rapidly due to concerns over delayed returns on massive AI investments. Market volatility could broaden further depending on US Treasury yields and elevated oil prices, warranting phased positioning and risk control.
