The industrial sector has spent years in tech's shadow. Now it's posting record highs, outperforming most of the market, and doing it with tailwinds from two directions at once. A US-Iran peace deal and surging AI-linked infrastructure spending have converged to make industrials the trade worth watching right now.

What drove the sector to a record

In mid-June, the S&P 500 Industrials Index hit a record after the US and Iran announced an interim peace deal. The agreement included reopening the Strait of Hormuz, a critical waterway for global energy trade.

Brent crude futures fell as much as 5.7% to $82.40 per barrel on the news. Lower oil prices directly cut costs for manufacturers and airlines, two groups that had been under pressure since hostilities began in late February.

The sector had slid into a correction during the conflict. It has now recovered ~14% from its late-March low.

United Airlines HoldingsUAL

and Delta Air LinesDAL

were among the top percentage gainers on the day of the deal announcement. Manufacturers like CaterpillarCAT

also rallied sharply.

The AI thread running through it all

The peace deal alone doesn't explain why industrials have climbed ~17% year-to-date, making it the S&P 500's third-best performing sector so far in 2026. The other engine is artificial intelligence.

Data centers require enormous amounts of power and cooling equipment. Companies inside the industrial sector supply both. Vertiv HoldingsVRT

and EatonETN

, which sell electrical and cooling systems for data centers, were among the session's leaders on the day the Iran deal was announced.

Caterpillar's story is the clearest example. Its power and energy segment now accounts for ~40% of company revenue, driven in large part by data-center capital spending.

Caterpillar's stock has climbed 78% year-to-date and crossed $1,000 per share for the first time, making it one of just two Dow Jones components trading above that level.

Tema ETFs investment partner Chris Semenuk described backlogs at companies like Caterpillar and GE VernovaGEV

as "unprecedented," citing what he called a "reindustrialization" theme.

What the manufacturing data shows

The sector rally isn't just sentiment. The underlying data is also moving in the right direction. Industrial production rose 0.1% in May according to the Federal Reserve. Year over year, output is up 1.7%.

The ISM Manufacturing PMI climbed to 54 in May, the highest reading in four years. The PMI is a monthly survey of factory activity where any reading above 50 signals expansion. That's the fifth consecutive month above the expansion threshold.

Where the technical picture points

Technical analyst Katie Stockton at Fairlead Strategies noted that industrials have broken out in absolute terms while also improving relative to the broader S&P 500.

The sector index sits above its rising 10-week and 40-week moving averages. The weekly MACD, a momentum indicator, has flashed a bullish crossover signal.

Stockton flagged General ElectricGE

as having a particularly compelling setup, with a measured move target near $458 if it confirms a breakout above $347.

Caterpillar's measured move target sits near $1.1K, with prior resistance around $930 acting as the key support level. GE Vernova needs a breakout above $1.18K to confirm renewed upside leadership.

On the M&A front, building-materials supplier CRH announced a deal to acquire rival Arcosa for ~$8.5B including debt, citing infrastructure megatrends as the strategic rationale.

The scale of these deals points to expectations of sustained growth rather than a short-lived recovery.
