Ideas
Carol Massar Anchor, Bloomberg 2:49
AI cloud demand remains very strong.
CoreWeave surged after AI spending drove faster-than-expected sales growth, with Q3 sales guided to $3.45B-$3.6B, a $104B backlog, and post-quarter customer commitments suggesting AI demand remains strong. Nebius also reported Q2 revenue that beat estimates and is up 193% year-to-date.
CoreWeave NEBIUS HIGH
Carol Massar Anchor, Bloomberg 3:53
AI optical equipment earnings beat expectations.
AI optical equipment names outperformed after Lumentum Holdings reported fiscal Q4 results that beat expectations and gave an outlook above analyst consensus; analysts are positive on the maker of optical equipment, and the strength pushed other names such as Fabrinet and Corning higher.

Vestas raised guidance and announced buyback.
Vestas Wind Systems rallied after lifting its full-year profit guidance and announcing a share buyback following a jump in turbine orders; investors are rewarding the company's turnaround.
VWDRY HIGH

US Antimony cut outlook, lower prices.
U.S. Antimony fell sharply after the mining company cut its full-year outlook for gross revenue and reported lower antimony prices, pressuring the critical minerals name.
UAMY MED
Romaine Bostick Anchor, Bloomberg 7:13
Cisco beat and guided above estimates.
Cisco beat fiscal Q4 adjusted EPS and revenue, and its current-quarter and full-year guidance came in well above Street expectations, sparking an upside knee-jerk reaction in the stock.
CSCO MED
Romaine Bostick Anchor, Bloomberg 8:12
Cerebras missed revenue and gross margin.
Cerebras Systems fell after Q2 revenue missed estimates and gross margin came in at 14% versus the 26.3% expected, raising questions even as cloud revenue beat. The stock had been up sharply into the print and was priced for higher expectations.
