Super Micro Computer closed at $30.83, up 20.88%, while Dell Technologies rose 9.67% to $443.25, making data center infrastructure the clear story of the session. The shared catalyst was a wave of demand for AI servers and networking gear that lifted both names simultaneously, signaling broad investor conviction in the buildout trade rather than a single-stock event.

Among the other gainers, Astera Labs added 3.62% to $331.38 and Cipher Mining climbed 4.46% to $23.91, rounding out a session that rewarded hardware and compute-adjacent names. AMC Entertainment also edged up 3.64% to $2.28, though its move appeared disconnected from the infrastructure theme.
