A number of stocks jumped in the morning session after dip-buyers moved into beaten-down semiconductor and hardware names following the sector's steepest one-day rout in 19 months.
The turnaround gained traction after President Donald Trump wrote on Truth Social that he is 100% in favor of artificial intelligence infrastructure, calling data centers "GOLD" and pledging to help states expand capacity, in comments carried by CNBC. That endorsement eased worries ignited by Democratic midterm victories and calls for data-center project halts.

AMD's shares are extremely volatile and have had 55 moves greater than 5% over the last year. But moves this big are rare even for AMD and indicate this news significantly impacted the market's perception of the business.
The previous big move we wrote about was about 23 hours ago when the stock dropped 15.2% on the news that incoming Democratic senators called for brakes on the development of artificial intelligence data centers following midterm election results.
As reported by CNBC, the political rhetoric fueled a widespread sell-off across the chipmaking industry, where companies depend heavily on the rapid buildout of computing infrastructure.
Separately, Reuters reported that Micron has paused work on a planned $4.5 billion memory-chip plant in Taiwan amid an extended labor dispute, according to a Bloomberg report cited by Reuters. The pause adds uncertainty around Micron's capacity expansion, but the report attributed it to labor negotiations—not the debate over U.S. data center construction.
Calls to halt or slow AI data center construction directly threaten demand projections for high-performance semiconductor components and processing units.
AMD is up 96.9% since the beginning of the year, but at $439.98 per share, it is still trading 32.3% below its 52-week high of $649.42 from October 2026. Investors who bought $1,000 worth of AMD's shares 5 years ago would now be looking at an investment worth $2,931.
