Arm's 17.19% advance to $323 led the session, and the breadth behind it was just as striking. Astera Labs, Digital Turbine, Intel, and DigitalOcean each finished more than 12% higher, making this one of the stronger broad-based days for technology and semiconductor names.
The gainers spanned very different corners of the market, from Astera Labs, Intel, and DigitalOcean to Digital Turbine, whose 12.76% gain is a notable move for a smaller-cap name sitting well below the others in absolute price.
Losses on the session were comparatively contained. Novo Nordisk was the worst performer among the decliners, falling 7.94%, and it stood alone as the only loss exceeding 4% across the tracked universe.
The energy names gave back ground in a measured way, with Exxon Mobil and Chevron each slipping less than 3% and Samsara and Dutch Bros each shedding less than 4%, keeping the overall tone of the session firmly positive.
