A wireless report splits the sector
Crown Castle climbed 7.5% in premarket trading after Bloomberg reported that SpaceX wants access to roughly 80,000 US cell sites for a nationwide wireless network. The tower owner was named as one of the parties in those discussions.
American Tower gained 3.3% on the same report. The company runs about 41,764 sites across the US and Canada, making it an obvious beneficiary of any large leasing deal.
The carriers took the other side. AT&T fell 4.2%, T-Mobile ($TMUS) slid 4.3% and Verizon dropped 3.6% as traders weighed a possible fourth national competitor. SpaceX is also buying low-band spectrum, according to the Bloomberg report.
Earnings reactions dominate the rest
RingCentral surged 15.5% after third-quarter results beat and management lifted guidance. The cloud communications firm now sees full-year adjusted earnings of $5.07 to $5.12 per share, above the $5.03 consensus, with revenue up 5.9% to $676M.
Robert Half surged 10.1% on its third-quarter beat, posting adjusted earnings of $0.49 per share against a $0.47 estimate. Its Talent Solutions arm grew revenue 2% from a year earlier, its first increase since 2022.
Deckers Outdoor dropped 6.7% after fiscal second-quarter revenue of $1.43B fell short of the $1.51B Wall Street expected, with HOKA and UGG both missing FactSet forecasts. Benzinga Pro data shows the company also cut its FY27 sales guidance below estimates.
Autoliv tumbled 6.3%. The airbag and seatbelt maker earned an adjusted $2.19 per share versus $2.31 expected, sales of $2.69B missed the $2.73B consensus, and it trimmed its full-year operating margin view to ~10.5%.
Western Digital fell 4.5% even after a fiscal first-quarter beat and an upbeat current-quarter forecast. The stock rose roughly 4% initially, then reversed during the earnings call as AI-spending worries resurfaced. Average selling price per terabyte jumped 28% in the quarter.
American Express slipped 2.5% despite raising its 2026 earnings outlook to $18.30-$18.60 per share from $17.30-$17.90. Third-quarter revenue grew 9% to $20.1B and card spending rose 8% to $454B.
Moderna declined 5.7%, extending Thursday's 25% collapse tied to a partial data leak on the cancer vaccine it's developing with Merck. The full dataset, released Thursday, read better than Wall Street anticipated.
SK Hynix rose 5.1% after shelving its review of a pre-IPO funding round and possible Nasdaq listing for NAND unit Solidigm, blaming market conditions and recent share moves.
Comfort Systems fell 3.6% as softer-than-expected margins overshadowed a third-quarter beat, though backlog grew 90% from a year earlier.
Schlumberger reports before the opening bell alongside other early filers. Traders are also watching the final University of Michigan consumer sentiment reading, with next week bringing a Federal Reserve decision and results from Microsoft, Alphabet and Amazon.
