UBS has downgraded the communication services sector from Attractive to Neutral, citing a more balanced risk-reward profile after strong performance and rising capital-expenditure expectations. The move comes as the bank shifts its sector preferences, now favoring consumer discretionary, financials, health care, industrials and utilities as its most attractive U.S. sectors.

In a note led by David Lefkowitz, UBS's CIO Head of US Equities, the bank acknowledged ongoing progress in AI adoption, including AI-driven improvements in content recommendations and advertising. However, the analysts noted that hyperscaler capital-expenditure forecasts are now significantly higher than expected, making near-term returns on this spend challenging. The intense competition between private and public AI model developers could weigh on free cash flow generation for some firms.

UBS also highlighted concentration risk within the sector, pointing out that Alphabet and Meta account for more than 75% of the total market capitalization. Despite the downgrade, the bank maintains a favorable view of the broader U.S. equity environment, citing resilient growth, supportive Federal Reserve policy, and continued AI investment and adoption.
