Apple shares fell 2% to $331.08 after Bank of America warned that Meta's Muse, an AI agent that performs online shopping and other tasks for users, could divert commerce activity from the iPhone ecosystem. Muse can browse websites, complete forms and continue tasks after users leave the app, with access to commerce services from Shopify, Expedia and PayPal; Amazon has blocked it. Bank of America's Wamsi Mohan said Apple could retain device sales while losing some product-discovery, referral and transaction activity that supports its high-margin services business. The bank kept its Buy rating and $370 price target, citing Apple's large installed base, user trust and privacy-focused technology. Meta shares rose 0.4% to $718.53, while Alphabet fell 0.9% to $339.51 and Microsoft declined 0.3% to $507.91. The Technology Select Sector SPDR ETF and Invesco QQQ Trust each fell 0.1%. Bloomberg News also reported that Apple chief executive John Ternus, the former hardware chief who succeeded Tim Cook, is planning a restructuring that would reduce middle-management layers, move away from fixed spring and fall launches and pursue new revenue streams as services growth slows.
