Caterpillar — Global PMI & Construction Cycle
Caterpillar (CAT) is the world's largest construction and mining equipment manufacturer — the purest large-cap proxy for global PMI and construction activity on NYSE. When global manufacturing expands (PMI above 52), Caterpillar's order books fill with excavators, bulldozers and mining trucks. When PMI contracts below 48, orders dry up. At PMI 51.4, Caterpillar is mid-cycle.
The PMI Signal: Global Manufacturing PMI above 52 is the sustained buy zone for Caterpillar. Below 48 is the trough. At 51.4, Caterpillar is in neutral territory — manufacturing is expanding but losing momentum. A 54% recession probability adds caution. Hold rather than add at current PMI levels.
Mining Equipment Cycle: Caterpillar's mining segment (large haul trucks, underground miners) tracks mining capex rather than PMI. Mining capex follows commodity prices with a lag — when iron ore, copper and coal prices are high for sustained periods, mining companies approve new fleet purchases. At current elevated commodity prices, mining capex is running but not at peak.
Infrastructure Spending Tailwind: The US Infrastructure Investment and Jobs Act ($1.2 trillion) and similar programmes in Europe and India provide a structural tailwind for Caterpillar's construction equipment beyond the PMI cycle. This multi-year infrastructure investment cycle provides partial insulation from PMI downturns.
Current Cycle Status: Mid-cycle hold. PMI 51.4 is positive but fading. Mining capex is elevated. Infrastructure spending provides a floor. Caterpillar's margins are at or near record levels — which is also a late-cycle warning signal. Hold existing positions; reduce if PMI falls below 49.

What is Caterpillar's primary cycle signal?
Global Manufacturing PMI is the primary signal. Above 52 is positive; below 48 is negative. Secondary signals include mining capex (tracks commodity prices) and construction activity. At PMI 51.4, Caterpillar is mid-cycle hold.
How does Caterpillar respond to US infrastructure spending?
The US Infrastructure Investment and Jobs Act ($1.2 trillion over 10 years) creates sustained demand for construction equipment — excavators, motor graders, compactors. This is additive to the PMI cycle signal and provides a floor during PMI downturns. Caterpillar estimates $100+ billion of addressable infrastructure spend.
What is Caterpillar's earnings at PMI trough?
At PMI trough (2015-16, 2019-20), Caterpillar's revenues fell 15-25% and EPS contracted sharply. The stock typically falls 30-40% from PMI peak to trough. The current elevated margins and record backlog are late-cycle characteristics — watch for PMI direction.
