Citigroup strategists say investors should move beyond the "Magnificent Seven" framework when assessing US equity moves tied to artificial intelligence. According to a Bloomberg report, the analyst team led by Scott Chronert recommends focusing on a broader growth cluster instead.
What changed and why it matters
Citigroup argues the "Magnificent Seven" label no longer accurately reflects how large growth stocks are behaving. The proposed growth cluster includes the largest technology companies and many firms involved in building AI infrastructure. That group now represents more than half of the S&P 500's market capitalization and accounts for about 48 percent of the index's earnings.
Market reshuffling supports the view: after driving S&P 500 records in prior years, the Bloomberg Magnificent Seven index underperformed in 2026 as investors favored sectors set to benefit directly from substantial AI spending.
Decoupling among the seven names
Price movements among the seven — Amazon, Nvidia, Meta, Apple, Microsoft, Tesla and Alphabet — have become less correlated. Microsoft and Meta weakened amid concerns over returns on multibillion-dollar investments, while Apple rose 23 percent after the market welcomed the company's decision not to enter an arms race over data-center expansion.
Semiconductor stocks led the rally in the first half of 2026 but have softened in recent weeks amid worries about stretched valuations.
Chronert's prior call and cluster valuations
Chronert had correctly predicted in December that AI-related market activity in 2026 would shift from firms providing technological underpinnings to companies applying AI. Citigroup notes the growth cluster still looks attractive on a historical basis: its 12-month forward P/E sits at the 66th percentile of the past 30 years, and strong profit expectations through 2027 support continued growth.
For these reasons, Chronert's team recommends that investors monitor the broader growth cluster rather than framing analysis as "Magnificent Seven versus the rest," arguing the cluster better reflects S&P 500 fundamentals and price performance.
