Analysis of US Market Trends and Korean Impact — 2026-04-27
US Market-Leading Sectors and Global Issues
1. AI and Rare Earth Themes
Rare earths—a common denominator for the AI, EV, and defense sectors—have emerged as a major market theme in the US. The related ETF, REMX, has reportedly seen a 160% rally over the past year. Expanding infrastructure investment in AI and the rapid adoption of electric vehicles are creating a structural increase in demand for rare earths, with investors also eyeing the sector's ties to the defense industry.
2. Big Tech Earnings Season
This week (April 27–May 1) is a "Super Week" for Big Tech earnings, which is expected to directly impact the Nasdaq and S&P 500 indices. As of April 23, both indices hit all-time highs, largely driven by hopes for a US-Iran peace deal. With the FOMC meeting also on the horizon, market volatility is expected to remain high.
3. Geopolitical Risk: US-Iran Negotiation Breakdown
The US negotiation team has effectively called off talks after cancelling their trip to Pakistan for a second round of peace discussions with Iran. This has reignited geopolitical risks in the Middle East, influencing international oil prices and defense-related assets. On April 21, markets saw a sharp spike followed by a reversal due to renewed tensions in the Strait of Hormuz.
Analysis of Key Player Statements
President Trump — Iran Talks Collapse and Shooting Response
-
Iran Negotiations: President Trump stated, "If Iran wants to talk, they should call," while abruptly canceling the US team's trip to Pakistan. This has heightened Middle Eastern tensions and bolstered investor sentiment toward the defense and energy sectors.
-
Correspondents' Dinner Shooting: President Trump was evacuated following a shooting incident at the White House Correspondents' Association dinner on April 25 (local time). Trump later remarked that "being president is a dangerous job" and added, "I don't want to live in fear." The incident has contributed to market volatility due to concerns over political instability.
-
Federal Reserve Leadership: Reports indicate that the Trump administration’s Department of Justice has transferred the investigation into Fed Chair Jerome Powell to the Fed’s inspector general, potentially clearing a path for a Trump-appointed successor (Kevin Warsh). Markets are growing increasingly cautious about a potential leadership change at the Fed.
Impact on Korean Markets and Promising Sectors
1. Rare Earth and Materials Sector
Given the 160% rally in the US REMX ETF and rising demand across AI, EVs, and defense, Korean rare earth materials companies are expected to benefit. Rare earths are essential for AI server cooling systems, EV motors, and defense equipment, pointing toward sustained structural demand.
- Notable sectors: Domestic rare earth materials companies.
2. Defense Sector
With the collapse of US-Iran talks, Middle East geopolitical risks have reignited, likely benefiting Korean defense firms. As of April, defense-themed stocks have been trending upward in Korea, with specific sectors seeing sharp gains due to escalating regional conflicts.
- Notable sectors: Domestic defense-related companies.
3. AI and Tech Sector
If the US Nasdaq continues its upward trend amid the Big Tech "Super Week," positive capital flows are likely to hit Korean AI semiconductor, equipment, and materials companies. As of April 21, the KOSPI stood at 6,219.09 (+0.44%) and the KOSDAQ at 1,174.85 (+0.41%), with investor sentiment favoring AI-related growth stocks.
