US Market Analysis & Korean Daily Briefing — 2026-10-24
US Market Review from the Previous Day
Major US indices showed mixed results amid growing skepticism over AI and escalating tensions in the Middle East.
- Nasdaq Plummets: Renewed doubts about AI hardware caused the semiconductor sector to tumble. Remarks by NVIDIA CEO Jensen Huang regarding capital shortages and Meta's massive spending announcement reignited concerns over AI funding, sending the Nasdaq down -2.6% to close at 26,008.
- Index Movements: The S&P 500 fell -1.2% to 7,663, while the Dow Jones Industrial Average inched up 0.02% to close at 52,866.
- Sector Rotation: Alongside the tech slump, investors shifted capital toward defensive plays. Consumer staples, utilities, and healthcare sectors rose, whereas tech-heavy indices declined.

Key Themes and Issues in the Korean Market
Despite the fallout from the tech correction originating in the US, certain sectors are expected to show differentiated movements in today's session.
- Semiconductor Substrate Strength: Domestic semiconductor substrate stocks gained strength as Samsung Electro-Mechanics drew attention over issues related to AI substrate partnerships.
- Index Drop and Increased Volatility: The KOSPI gave up its rebound gains after just one day, opening lower and slipping back below the 5,600 level. The KOSDAQ also dropped 2.5%, trading around the 781 mark amid high market volatility.
- Awaiting Macroeconomic Events: The Bank of Korea's Monetary Policy Committee meeting and foreign investor flow trends are expected to be key variables determining intraday direction.
