Commentary

US markets face renewed cross-currents as the Trump administration’s sweeping tariffs on 15 countries add to trade uncertainty and supply chain risk 1. The move, which targets key Asian and emerging-market exporters with duties of up to 40%, is likely to pressure import-dependent sectors and could trigger retaliatory measures 1. Traders should monitor for potential volatility in equities tied to retail, autos, and electronics, as well as any currency moves in affected EM markets 1.

The AI sector remains highly active. Meta ’s recruitment of Apple ’s AI models chief 3 and Amazon ’s disclosure of its massive Project Rainier supercluster 4 reinforce the ongoing investment and competition among US tech giants. This keeps the focus on semiconductors, cloud infrastructure, and large-cap tech names 34. Apple may face questions about its AI roadmap 3, while the upcoming Grok 4 launch from xAI 6 and Waymo’s expansion into new cities 7 highlight persistent innovation in both AI and autonomous vehicles.

In Europe, the EU’s push to finalize €150B defense loan agreements with the UK and Canada, alongside talks for reciprocal tariff relief with the US, could support defense and industrial names on both sides of the Atlantic 5. Meanwhile, Texas faces ongoing disruption from deadly flooding, with implications for insurers and regional consumer activity 8. The US measles outbreak—now at a 33-year high—adds a layer of public health risk, especially in the Southwest 14.

Crypto markets are watching Pump Fun’s $600M token sale, though details remain limited 9. The visible deployment of the California National Guard in Los Angeles 15 and the security incident in Gaza 2 may not move US markets directly but add to the broader geopolitical and domestic policy backdrop.
