what happened
Monolithic Power Systems shares climbed 5.6% and Photronics gained 4%, according to StockStory. Dip-buyers moved into beaten-down semiconductor and hardware names after the sector suffered its steepest one-day drop in 19 months.
The rebound was helped by a post from President Donald Trump on Truth Social, in which he said he fully backs artificial intelligence infrastructure, called data centers a form of gold and pledged to help states expand capacity. The comments eased worries stoked by Democratic gains in the midterm elections and calls to halt data-center construction.
Separately, Bureau of Labor Statistics data showed October nonfarm payrolls rising by 165,000, which lifted Treasury yields and weighed on the Dow. Chipmakers, however, recovered previous losses regardless of that backdrop. Reuters, citing Bloomberg, also reported that Micron has paused work on a $4.5 billion memory-chip plant in Taiwan amid a prolonged labor dispute.
why it matters
Calls to slow AI data-center construction directly threaten demand forecasts for high-performance chips, so the sector tends to swing sharply on any news about AI infrastructure. MPWR is up 28.4% year to date but remains 28.9% below its 52-week high, and the stock has had 36 moves greater than 5% over the past year.
