U.S. Market Analysis & Korea Daily Briefing — 2026년 6월 14일
Summary of Previous U.S. Market

The U.S. market closed mixed yesterday, caught between warnings from President Trump regarding Iran and a sell-off in the AI sector. The Nasdaq dipped 1.98% intraday but found some relief thanks to a strong rally in semiconductor stocks.
Key Indicators:
- Nasdaq: Dropped up to 1.98% intraday before partially recovering, supported by a semiconductor rally (+7.91%).
- U.S.-Iran Military Tensions: Ongoing U.S. airstrikes have heightened instability in the Middle East.
- AI and Semiconductor Sector Volatility: Increased volatility following the sell-off in AI stocks, countered by the semiconductor rally.

Key Themes and Issues in the Korean Market
1. Escalating Geopolitical Risks in the Middle East and Continued Volatility
Renewed military tensions between the U.S. and Iran are driving increased volatility in the Korean stock market. Instability in the Middle East is sparking concerns over rising energy prices and a global economic slowdown, which could negatively impact Korea’s export-heavy economy.
Related Issues: Rising crude oil prices, increased prospects for U.S. interest rate hikes, and uncertainty in defending the KOSPI 8,000 level.
2. Partial Recovery in Semiconductors and AI-Related Volatility
Yesterday's 7.91% surge in the U.S. semiconductor index sent a positive signal to domestic chipmakers like Samsung Electronics and SK Hynix. However, adjustment pressure remains due to the lingering effects of the AI sell-off. Amidst the 2026 AI supercycle hypothesis, the recovery of HBM (High Bandwidth Memory) demand remains a key point to watch.
Related Issues: Surging HBM demand, semiconductor supercycle, and the impact of the KRW/USD exchange rate (staying in the 1,440 won range).
3. The Duality of High Growth and High Volatility in the Korean Economy
While the domestic GDP is seeing its sharpest growth in half a century, the economy is simultaneously experiencing deepening polarization and a highly volatile market environment. This makes careful individual stock selection more important than ever.
Related Issues: Highest growth in 50 years, deepening imbalances and volatility, and expectations for capital market revitalization.
Recommended Stocks to Watch Today
1. Samsung Electronics (005930)
Reason: A semiconductor bull market is forming following the 7.91% surge in the U.S. semiconductor index. It is seen as a core beneficiary of the AI supercycle, with HBM demand rising rapidly. Yesterday’s U.S. semiconductor rally provides a positive signal.
2. SK Hynix (000660)
Reason: Earnings are expected to be driven by increased HBM production, making it a key stock to benefit from the full-scale recovery phase of the semiconductor industry. If the KRW/USD exchange rate remains in the 1,440 won range, export profits are also expected to be secured.
3. Defense and Energy-Related Stocks
Reason: Heightened geopolitical tensions in the Middle East are improving the profitability and demand for the defense and energy sectors. The trend of rising U.S. oil exports and global energy prices is expected to drive earnings for these companies.
