US Stock Market and Korea Daily Briefing — 2026-10-10
Overnight US Market Summary
The US market saw the S&P 500 and Nasdaq indices decline together yesterday as rising oil prices and Treasury yield pressures combined.
- Major Index Performance: On October 8 (local time), the S&P 500 fell 0.47% to close at 7,765.13, and the Nasdaq Composite plunged 1.25% to 27,193.29. Meanwhile, the Dow Jones Industrial Average ticked up 0.10% to 51,231.16.
- Decline Factors and Sector Trends: A sharp spike in international crude oil (WTI exceeding $102 per barrel) and multi-year highs in US Treasury yields dampened investor sentiment. Growth stocks and AI-related tech stocks, which are sensitive to interest rates, experienced significant corrections.
- Market Sentiment: With the Federal Reserve's hawkish stance reaffirmed, the market adopted a defensive posture. The energy sector showed relative strength bolstered by rising oil prices, but overall risk-off sentiment prevailed.
Key Themes and Issues in the Korean Market
Today's Korean market is expected to be driven by a combination of overnight US market declines and domestic supply-demand factors.
-
Short-term Correction Pressure on Semiconductor and AI Sectors Following yesterday's 1% drop in the Nasdaq and weakness in AI-related stocks, domestic semiconductor leaders and AI infrastructure stocks are likely to see short-term profit-taking. However, expectations for a mid-to-long-term industry recovery remain intact.
-
Increased USD/KRW Exchange Rate Volatility Rising US Treasury yields and risk-aversion sentiment are putting upward pressure on the USD/KRW exchange rate. This could encourage foreign net selling, making it a time to focus on domestic-oriented or currency-hedged stocks rather than exporters.
-
Testing KOSPI Support Levels Yesterday, the KOSPI index dropped over 1% to fall back into the 6,700 range. If institutional and foreign joint selling continues, further downside testing is expected, making a strategy of checking individual stock earnings momentum rather than index direction more effective.
Stocks to Watch Today
Reflecting yesterday's energy sector strength and tech weakness in the US market, the following stocks warrant monitoring:
-
S-Oil: The US energy sector showed strength yesterday following the surge in international crude oil prices. Domestic refining and chemical sectors can also benefit from higher oil prices, making it worth watching from a short-term trading perspective.
-
Samsung Electronics: A representative stock that could attract bargain-hunting inflows due to perceptions of excessive declines amid market-wide downward pressure from US tech corrections. The structural growth story for the semiconductor industry remains valid.
-
Hanwha Solutions: Alongside renewable energy policy expectations, the solar sector could gain relative prominence as an alternative energy source driven by rising oil prices. Its defensive strength during volatility periods is drawing attention, especially aligned with recent energy security issues.
