Chart of the Day

Every one of the day's eight biggest gainers came from AI infrastructure: cloud-capacity provider CoreWeave jumped 24.71%, and memory and storage makers Sandisk, Micron and Seagate posted gains near or above double digits. Microsoft, one of the biggest spenders on that same infrastructure, fell 2.26%; investors rewarded the suppliers collecting the spending rather than the company writing the checks. The technology fund led all sectors with a 3.23% gain and the Nasdaq 100 rose 2.31%. The rally was not narrow either: 10 of 11 sectors closed higher, and across the broad universe 336 stocks advanced against 169 decliners. No major data release drove the session; the move looked like a rebound in chip and infrastructure names that had been sold hard in recent weeks. The technology fund is still down 11.17% over 21 sessions, so watch whether these names can hold their gains in the coming days.
