> Micron rose 11%, while Marvell, Arm, Intel and Nvidia also advanced during Wednesday’s session.

CoreWeave shares climbed 21% to a two-week high during Wednesday’s morning U.S. trading, while the Philadelphia Semiconductor Index rose 5%, linking one steep stock move with gains across the broader chip sector.

The semiconductor advance included Micron, up 11%; Marvell, up 9%; Arm, up more than 8%; Intel, up 7%; and Nvidia, up more than 3%. All five names were higher in the same session as the index, and CoreWeave also extended its rally.

The index’s 5% gain gives a sector-wide measure alongside the individual stock moves. CoreWeave’s two-week high marks a separate milestone for its shares, which rose alongside the chip stocks during the session. Taken together, the day’s moves covered CoreWeave, five named chip companies and the Philadelphia Semiconductor Index, giving U.S. market readers a snapshot of strength across AI infrastructure and semiconductors. The figures were current at 10:45 a.m. ET (15:45 UTC), while Wednesday’s session was underway.
