Artificial Intelligence (AI), Electric Vehicles (EVs), and defense—the "hottest" themes in the U.S. stock market—all rely heavily on rare earth elements. REMX, an ETF focused on rare earths, has rallied nearly 160% over the past year.
3. Hopes for Easing Geopolitical Risks — U.S.-Iran Negotiations
Hopes that volatility stemming from the U.S.-Iran conflict might ease are acting as a positive catalyst. However, uncertainty remains as negotiations face difficulties.
- President Trump canceled his Iran negotiation team's trip to Pakistan, stating, "If Iran wants to talk, they can call."

Key Figure Commentary
Elon Musk — Unveiling Tesla HW4 Plus
Attention is focused on Tesla's announcement regarding its next-gen autonomous driving computer, 'HW4 Plus.' During the quarterly earnings call, Musk revealed that the new AI4.1 (or AI4 Plus) chip will double the memory, featuring 32GB of RAM per chip for a total of 64GB of system memory.

- Trump effectively canceled the second round of negotiations with Iran, increasing uncertainty. His comment, "If Iran wants to talk, they can call," has made the future of these talks unclear.
- Market Implications: The potential for renewed Middle East tensions increases volatility in the energy and defense sectors, while safe-haven assets may gain favor if risk aversion intensifies.
Federal Reserve FOMC — Policy Announcement Expected This Week
- Analysts warn that tech stock volatility could rise if the 10-year Treasury yield approaches 4.5% following the Fed's policy announcement this week.
- Market Implications: The rate decision directly impacts foreign capital flows and exchange rates in the Korean market. A dovish tone from Chair Powell would be a positive factor for emerging markets.
