Overview
- Citi's strategists published guidance Monday saying the seven-stock label no longer describes where AI-related earnings are concentrated and that investors should use a broader 'growth cluster' framework.
- The growth cluster expands beyond the Magnificent Seven to include chip and AI-infrastructure firms and Citi suggested adding names such as Broadcom, Micron, and AMD.
- Citi estimates the cluster accounts for roughly 48%–55% of S&P 500 expected earnings and reports the group gained about 25% in Q2 and roughly 12% year-to-date versus the S&P 500's 15% Q2 rise and 10% YTD.
- Analysts warn heavy AI capital spending could cut free cash flow for the largest tech companies, a dynamic that has put pressure on Microsoft and Meta while Apple has outperformed after avoiding the biggest data-center spending race.
- The shift could change index and ETF leadership, influence stock selection toward semiconductors and infrastructure, and make monitoring AI capex and cash-flow trajectories central to assessing tech valuations.
