Wall Street saw a risk-off turn as investors weighed mixed U.S. trade messages in the wake of a Supreme Court decision on President Donald Trump’s tariffs, plus talk of additional duties in the mix. “Obviously, the extra layer of uncertainty that comes from the Supreme Court ruling and what trade policy looks like now isn’t helping,” said Ross Mayfield, an investment strategy analyst at Baird.

Shares have moved in step with investor bets on the next wave of chip capex, especially gear tied to advanced packaging and AI server memory. Earlier this month, Applied put out a quarterly sales outlook that topped forecasts. CEO Gary Dickerson told investors DRAM—mainstream memory in most computers—should be Applied’s fastest-growing business in 2026. Reuters
At the heart of the debate: high-bandwidth memory, or HBM. This advanced memory, built by stacking DRAM chips, typically shows up alongside AI processors inside data centers.
The flip side is pretty clear—tariffs ramping up can shake demand projections, and if AI data-center construction pauses, tool orders could slow almost immediately. A minor tweak in how customers plan their capital spending might end up triggering a larger swing in equipment shares.

Until that point, AMAT is shaping up as a sentiment gauge for traders — equal parts macro vibes, AI capex proxy, and a positioning play.
