Something remarkable is happening on Wall Street, and it's turning the conventional investing playbook on its head. In the first five weeks of 2026, billions of dollars have fled the high-multiple technology and software-as-a-service stocks that dominated markets for years, pouring instead into the sectors that Wall Street spent the past decade dismissing as relics of a bygone era: basic materials, energy, and industrials.
The numbers are striking. Basic materials have surged 9.05% year-to-date, leading all eleven S&P 500 sectors. Energy and industrials are close behind. Meanwhile, the tech-heavy Nasdaq Composite has slumped into negative territory for the year, and the once-vaunted "Magnificent Seven" trade—the idea that a handful of mega-cap tech companies would perpetually outperform everything else—is fracturing in real time.
The Earnings Gap Is Closing
For years, the bull case for mega-cap tech was simple: these companies were growing earnings so much faster than everyone else that their premium valuations were justified. That narrative is cracking. The earnings growth differential between the "Magnificent Seven" and the rest of the S&P 500 has narrowed sharply, and analysts expect it to compress further throughout 2026.
"We are most definitely seeing a rotation, and it has picked up some momentum from the end of last year. The gap between technology earnings growth and the rest of the market is closing."
— Michael Arone, Chief Investment Strategist, State Street
The math behind this convergence is straightforward. Tech companies are spending unprecedented sums on AI infrastructure—Alphabet alone committed up to $185 billion in 2026 capital expenditure—which pressures margins even as revenue grows. Meanwhile, industrial and materials companies are riding a wave of infrastructure spending, reshoring initiatives, and AI-adjacent demand that is accelerating their own earnings growth from a much lower base.
AI Is Ironically Fueling the 'Old Economy' Renaissance
Here's the twist that many investors missed: the very AI revolution that was supposed to cement tech's dominance is generating enormous demand for physical infrastructure—the kind built with copper, steel, concrete, and natural gas. Data centers projected to consume 48.3 gigawatts of power in 2026 need cooling systems, electrical equipment, construction materials, and energy supplies. Every dollar spent on AI servers creates downstream demand for the "old economy" companies that produce these essential inputs.
Vertiv Holdings, a leader in data center cooling systems, has become one of the most sought-after names in institutional portfolios, with revenue growth expectations exceeding 20% in 2026. Caterpillar, the 100-year-old heavy equipment maker, is seeing surging demand for the earthmoving equipment needed to build data center campuses. Even copper miners are being revalued as the metal becomes critical for the massive electrical requirements of AI infrastructure.
Small Caps Are Leading the Charge
The rotation isn't limited to large-cap value stocks. Small-cap companies are outperforming their large-cap counterparts in both the value and growth indices, suggesting that the capital reallocation is broad-based rather than confined to a few defensive names. In the value index, small caps are up 5.94% compared to large-cap returns of 2.80%. Even within growth, small caps lead at 6.02% versus large-cap growth's anemic 0.13%.
This makes sense when you consider that small-cap companies are disproportionately domestic, making them beneficiaries of reshoring trends and less vulnerable to the tariff uncertainty that continues to weigh on multinational tech companies. The Trump administration's trade policies, which include tariffs on imported goods, have created a structural tailwind for domestic producers in materials and manufacturing.
The Tariff Tailwind
Trade policy is providing additional fuel for the rotation. Tariffs on imported steel, aluminum, and other materials have created pricing power for domestic producers that didn't exist two years ago. While these same tariffs are raising costs for tech companies that depend on global supply chains for components and devices, they're boosting margins for the very industrial and materials companies that are now attracting investor capital.
The irony is profound: the policies designed to revive American manufacturing are succeeding, but the beneficiaries are the companies that Wall Street had long written off as low-growth value traps. Steel producers, chemical companies, and energy firms are posting earnings growth rates that rival what tech companies delivered during the early stages of the AI boom.
How Long Can the Rotation Last?
The critical question is whether this represents a temporary flight to safety amid tech turbulence or a genuine structural shift in market leadership. History suggests that sector rotations of this magnitude, once established, tend to persist for quarters or even years. The last comparable rotation—from growth to value in late 2021—lasted well into 2022 before reversing.
Several factors suggest this rotation has staying power. First, the earnings convergence between tech and the rest of the market appears structural, not cyclical. Second, the physical infrastructure demands of AI will create multi-year demand tailwinds for materials and industrial companies. Third, geopolitical trends toward reshoring and supply chain diversification favor domestic producers over globally dependent tech firms.
For investors who spent the past decade concentrating portfolios in technology, the message is clear: diversification is no longer just a risk management tool—it's an opportunity to capture the next wave of market leadership. The "old economy" isn't dead. It's being reborn, and the smart money is already there.
