US Market Trends and Their Impact on Korean Stocks — 2026-05-09
Leading Sectors in the US Market and Global Issues
1. Semiconductor and Tech Sector Surge
The New York stock market saw a massive rally in the semiconductor sector on May 6 (local time).
- Major chip stocks led the charge, with AMD surging 19% and Intel rising 5%.
- The PHLX Semiconductor Sector (SOX) climbed 4.48%, fueling a broader rise in tech stocks.
- According to reports by the Korea Economic Daily, the US market is increasingly dependent on five major Big Tech companies to drive index gains, leading to warnings that a "tech sector shock could hit the entire market."
2. Easing Geopolitical Risk: US-Iran Peace Expectations
- Reports of discussions between the US and Iran regarding the signing of a Memorandum of Understanding (MOU) to end the war positively impacted the market.
- Expectations of peace caused the dollar and US Treasury yields to plummet, while the price of gold (XAU/USD) jumped over 3% during the day, reaching the $4,700 level.
- Oil prices fell by 7%, reflecting hopes for lower energy costs, which acted as a positive tailwind for consumer and industrial goods sectors.
3. Strong US Private Employment Data for April
- US private employment data for April exceeded market expectations, reinforcing hopes for a soft landing for the economy.
- Robust employment boosted consumer sentiment and earnings forecasts, providing additional momentum for the stock market.
Key Issue-Maker Statements
1. President Trump: Continued Pressure on Chair Powell for Rate Cuts
On May 4 (local time), President Trump posted a composite image of Fed Chair Powell in a trash can on his social media platform, Truth Social. He mocked the situation, stating, "Too Late is a disaster for the USA," and urged an immediate interest rate cut. This rhetoric continues to fuel market uncertainty regarding the Federal Reserve's independence.
2. Fed Chair Powell: Exiting with a 'Hawkish Hold'
According to Digital Daily, despite constant pressure from Trump to lower interest rates, Chair Powell appears to be ending his term by maintaining a so-called "hawkish hold." The market is focused on the selection of his successor, and the resulting uncertainty in monetary policy is seen as a factor increasing market volatility.
3. Chinese Market Rises: Corning News and Fiber Optics Strength
According to NewsPim, China's A-shares also rose on May 7, following the US-Iran peace developments. Specifically, positive news involving Corning boosted the fiber optics sector, and the Shanghai Composite Index rose 0.48% to 4,180.09. This reflects expectations for improved global supply chains and technology infrastructure demand, which could indirectly affect related Korean material and component firms.
Impact on Korean Stocks and Promising Sectors/Stocks
1. Semiconductor and IT Hardware Sector
The surge in AMD and Intel and the strength of the PHLX Semiconductor Index are direct tailwinds for the Korean semiconductor value chain. However, on May 8, the domestic market saw profit-taking in semiconductors due to renewed uncertainty over US-Iran negotiations, leading to weakness during trading hours.
- Major domestic firms like Samsung Electronics and SK Hynix are classified as direct beneficiaries of the strength in US Big Tech and chip sectors.
- BH confirmed improved performance for Q1 2026, recording consolidated revenue of 371.5 billion won (+11.77% YoY) and an operating profit of 10.6 billion won (turning to profit).
- KB Financial Group research recommends a "gradual increase in weighting" for the Korean stock market from a long-term investment perspective.
2. IT Services and Transportation Sectors
According to Hellot, while semiconductors faced profit-taking on May 8, the IT services and transportation sectors showed strength, leading the index to turn positive. These sectors attracted significant institutional buying, making them attractive for short-term investment. Further confirmation of specific stocks in these sectors is needed based on daily trading data.
3. Satellite Communication and Defense Themes
AP Satellite announced that it signed a contract worth 6.273 billion won (13% of recent revenue) to supply satellite communication terminals to the global satellite operator THURAYA. Even as geopolitical risks between the US and Iran ease, demand for defense and communication infrastructure tends to remain steady, keeping the satellite communication theme in the spotlight.

|---|---|
| Dow Jones 30 | +1.24% (49,910.59) |
| S&P 500 | Record High |

On May 8, the domestic stock market followed the rally from the US, but faced volatility during the day due to US-Iran negotiation uncertainty and profit-taking in the semiconductor sector. It eventually closed higher, supported by gains in IT services and transportation, along with strong institutional buying. With issues surrounding the Fed chair replacement and Trump's pressure for rate cuts continuing, future monetary policy uncertainty is expected to be the key variable for market volatility.
