AI-Heavy BELT ETF Sees 14× Volume Surge Amid Microsoft Pullback

BlackRock Long-Term U.S. Equity ETF (BELT) has seen unusual trading volume, which is 14× higher than its average daily volume.

BELT is heavily tilted toward mega-cap tech, and several of its top holdings are in the spotlight, with Microsoft (6.2% weight) facing a sharp share-price pullback amid investor concerns over heavy AI spending, slightly slower Azure growth, and fresh U.K. regulatory scrutiny of its cloud business, even as analysts largely frame the weakness as a long-term buying opportunity and note its massive revenue backlog. Broadcom (7.4%) continues to benefit from AI enthusiasm after a series of bullish analyst notes highlighting its long-term TPU co-design and networking deal with Google through 2031, which could deliver substantial incremental revenue as AI data centers scale. ASML (6.1%) has rebounded strongly despite U.S. efforts to tighten export controls on advanced chipmaking tools sold into China, while Intel (4.9%) is drawing attention for a still-murky but market-cheered deal to support Tesla’s Terafab system and a new GaN-silicon power chip initiative that could boost its data center positioning; Amazon (8.1%) also features in the AI narrative, with analysts citing it alongside Microsoft as a key beneficiary of rising software and AI budgets.
