Notable movers

Super Micro Computer, Inc. (SMCI) +19.02%

CoreWeave, Inc. (CRWV) +19.28%

Second-quarter revenue exceeded expectations, the loss was milder than analysts anticipated, and management said enterprise AI demand was accelerating. A nearly 20% earnings move on more than $9 billion of regular-session turnover made CoreWeave a central read-through for AI-cloud demand.

Dell Technologies Inc. (DELL) +9.87%

Dell rallied as a major sympathy beneficiary of strong CoreWeave and Super Micro results, which reinforced expectations for sustained spending on AI servers and infrastructure. The nearly 10% move in a company valued above $300 billion showed the earnings read-through was not confined to smaller, higher-beta AI names.

Micron Technology, Inc. (MU) +4.92%

Micron advanced with the AI-infrastructure complex after CoreWeave and Super Micro results supported expectations for continued demand for high-performance memory.

Sandisk participated in the AI-infrastructure and memory rally following strong CoreWeave and Super Micro results, with its flash-storage exposure providing a direct capacity-expansion read-through. The stock added nearly 6% on roughly $16 billion of turnover, making it one of the session's largest liquid expressions of the AI-storage theme.

The Wendy's Company (WEN) +14.70%

Shares reacted to renewed reports that activist investor Trian was exploring a potential take-private transaction; no definitive agreement or company filing was identified. A takeover-driven double-digit move in a heavily shorted, institutionally owned restaurant company highlighted M&A interest in depressed consumer franchises.

D.R. Horton, Inc. (DHI) -2.94%

Homebuilders weakened as elevated Treasury yields pushed long-term mortgage rates to their highest level in a year, worsening housing-affordability concerns. The largest U.S. homebuilder underperformed despite falling Treasury yields during the session, highlighting concern over the lagged effect of already-high mortgage rates.

Builders FirstSource, Inc. (BLDR) -3.58%

The building-products supplier declined with homebuilders as high mortgage rates intensified concern about construction volumes and housing demand. Its larger decline than the major builders showed the housing-rate concern extending into upstream suppliers with operational leverage to construction activity.
