Retail traders are shifting from the Magnificent Seven to AI infrastructure stocks, like SK Hynix and Marvell; five of the Mag Seven stocks trail the market YTD
Once the Magnificent Seven's most enthusiastic fans, they are looking elsewhere for the next superstar tech stocks
Context & Ripple Effects
The Magnificent Seven were the market’s clearest AI trade in 2023, when their median gain far outpaced the S&P 500. But projected slower combined profit growth for the group and the fact that five now trail the market this year give retail investors a reason to look beyond the original winners.
The rotation also follows evidence that AI-linked returns have spread into the supply chain: data-storage stocks led the S&P 500 in 2025. SK Hynix and Marvell offer retail traders more direct exposure to the infrastructure layer underpinning AI spending.
First-order effects
- Retail buying attention shifts away from the large platform stocks toward SK Hynix and Marvell, while the five lagging Magnificent Seven names lose some of the retail-flow support that helped define the earlier AI rally.
- SK Hynix faces greater investor focus on whether it can expand memory output fast enough, while Marvell becomes a more prominent listed proxy for AI infrastructure demand.
Second-order effects
- The AI equity trade broadens from a concentrated group of Big Tech leaders into memory, storage and networking suppliers, encouraging investors to judge companies on their position in the infrastructure supply chain rather than on AI branding alone.
- Retail participation can amplify price sensitivity around production-capacity updates and demand signals at infrastructure suppliers, particularly after storage stocks’ unusually strong prior-year performance.
Third-order effects
- If the rotation persists, AI-market leadership may become less concentrated in consumer and cloud platforms and more cyclical across the semiconductor and data-infrastructure stack.
- The shift tests the claim that AI demand can smooth the memory industry’s historic boom-and-bust pattern; durable leadership would require infrastructure demand to hold up beyond a momentum-driven re-rating.
The trend: AI investing is moving from a narrow platform-stock trade toward a broader, more financially active bet on the hardware and supply-chain layers supporting AI deployment.
