Nobody planned to own Caterpillar over Nvidia this year. That was not the consensus going into January. It was not the trade anyone was pitching at conferences. But that is more or less what happened.

A sector rotation is well underway. Industrial, consumer defensive, and energy stocks are outperforming the broader market by a wide margin, offsetting softness in technology, communication services, and consumer cyclicals. The story heading into July is not about AI fading. It is about who else gets paid from the AI buildout.

The XLI industrials ETF gained roughly 17% in the first half of 2026, with Caterpillar up more than 60% year to date and GE Vernova up approximately 71%. Caterpillar reached an all-time high above $1,073 in late June. The market has decided CAT is no longer a cyclical equipment maker. It is an AI infrastructure play, because its Power and Energy segment supplies the generators and turbines that keep data centers running.

This is the part that gets underappreciated. The industrials trade is not a rejection of the AI trade. It is a derivative of it. The physical world has to be built before the digital world can run.

The Capex Story Nobody Fully Owns Yet

Hyperscalers have been revising their AI-related capital spending projections sharply higher. The numbers being discussed for 2026 are in the range of $650 billion across the major cloud and tech platforms, up more than 50% from 2025 levels. State Street remains constructive on industrials as the sector benefits from AI-driven infrastructure spending, rising defense budgets, and pro-capex fiscal policy. The framing is picks-and-shovels, across the full AI value chain.

Here is where it gets interesting. The capex wave is no longer contained to data centers. Capital spending growth has been spreading into metals, machinery, and broader industrial manufacturing. The strongest gains have appeared in three areas: primary metals, fabricated metal products, and industrial machinery. Orders for primary metals have risen as construction and automotive demand stabilizes. Fabricated metal products, used across energy, infrastructure, and defense supply chains, have also posted gains. Industrial machinery orders, a bellwether for factory investment, have climbed as manufacturers expand capacity.

Slight tangent, but it matters: Eaton posted a first-quarter 2026 record of $7.5 billion in revenue on 10% organic growth, raised its full-year organic growth midpoint to 10%, and reported Electrical Americas orders surging 60% year over year. Data center orders within that segment accelerated 240%. That is not a rounding error. That is a structural shift in demand.

The First Half in Numbers

The Russell 2000 gained 22% in H1 2026, its best first-half performance since 1991. The S&P 500 returned 9.6%. The Nasdaq climbed 12.8%. Tech did not collapse. But it did not lead.

Two separate expressions of the same underlying theme. Most investors have only owned one of them.

Inside large caps, AI capex has concentrated in memory semiconductors. Inside smaller names and industrial mid-caps, it has flowed into power equipment, electrical infrastructure, and machinery tied to data-center buildouts. The XLI performance, roughly 17% year to date as of late June, reflects that second current of demand. Less discussed. Probably underowned.

What Q2 Earnings Need to Show

The rotation trade has a specific vulnerability. It is predicated on earnings following the spending. Analysts have been upgrading their estimates. Full-year 2026 earnings estimates have moved higher for eleven of sixteen Zacks sectors since the start of March, with the most pronounced gains in Energy, Basic Materials, Tech, Industrials, Utilities, and Business Services. Total S&P 500 earnings for Q2 are expected to grow roughly 21-22% year over year.

But the risk is real. If economic data weakens and growth expectations deteriorate, the entire rotation could unravel. The Q2 earnings reports kicking off the week of July 14 with major banks are the first real test of whether the spending commitments are flowing through to actual revenue and margins for the picks-and-shovels names.

GE Vernova reports Q2 results around July 22-29. Caterpillar reports August 4. Watch GEV’s order backlog, which already reached $163 billion in Q1 with a 2.0 book-to-bill ratio. Watch Caterpillar’s Power and Energy segment margin, which faced tariff headwinds of $2.2 to $2.4 billion for the full year. Watch Eaton’s data-center order commentary against that 240% Q1 growth rate. Those three data points will tell you more about the health of this trade than any macro number.

Bull / Base / Bear

Bull: A surge in capital expenditures redirects economic energy into the physical world. Massive government and private-sector investment in infrastructure, domestic manufacturing, and the energy grid creates tangible demand for real goods and services. This capex wave directly benefits industrial and materials companies, creating a durable, multi-year tailwind that the stock prices have only partially reflected.

Base: Industrials hold their year-to-date gains through earnings season. Q2 results confirm that AI infrastructure spending is translating into real order growth for power equipment and industrial machinery companies. The sector finishes 2026 with high-single-digit earnings growth and modest multiple expansion. CAT and GEV give back some of their runs but remain well above where they started the year.

Bear: The rotation is predicated on rates staying elevated and capex staying elevated. If the macro story flips, a flight to safety and liquidity could trap capital in real-economy stocks whose earnings growth disappoints. CAT is already trading at roughly 39x forward earnings. GEV is trading at about 40x NTM EV/EBITDA, more than double the sector median. There is not a lot of margin for execution error at those levels.

The Stocks in Focus

• Caterpillar (CAT): Up more than 60% in 2026, now trading at roughly 39x forward earnings after hitting an all-time high above $1,073 in late June. Q1 2026 sales rose 22% year over year to $17.4 billion. The Power and Energy backlog reached a record near $63 billion, up 79% year over year. Earnings due August 4.
• GE Vernova (GEV): Up approximately 71% year to date. Q1 2026 revenue came in at $9.34 billion, orders surged 71% year over year to $18.3 billion, and backlog expanded to $163 billion. Management raised full-year 2026 revenue guidance to $44.5 to $45.5 billion. Earnings due around July 22. GEV was spun off from General Electric in April 2024 and is targeting $200 billion in backlog by 2027.
• Eaton (ETN), Emerson Electric (EMR): Both are quietly compounding through electrical infrastructure demand. Eaton’s Electrical Americas orders surged 60% year over year in Q1, with data center orders up 240%. Less covered than the semiconductor names. Probably underowned by the average retail portfolio.

What the Rotation Means for Positioning

The market’s H1 2026 gains were driven by a narrower source of demand than the index-level numbers imply. AI infrastructure spending powered much of the rally. The next phase depends on whether the broader economy begins to participate in that growth or whether the capex wave stays concentrated at the top of the tech stack.

That framing matters. If the next phase is broadening, industrials are already positioned for it. If it isn’t, the rotation could stall at the sector level even if individual capex beneficiaries hold up.

The question heading into Q2 earnings isn’t whether the AI buildout is real. That answer is settled. The question is whether the physical economy is actually absorbing that spending the way the stock prices are implying it should.

We start getting answers this week.
