ABB vs ROK: How ABB Ltd and Rockwell Automation Compare (2026)
Last updated July 2026
Short answer
ABB (ABB Ltd) and ROK (Rockwell Automation) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
Before you buy: how ABB and ROK affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ABB and ROK share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ABB and ROK exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.
What does ABB Ltd (ABB) do?
ABB Ltd is a global technology company headquartered in Zurich, Switzerland, that builds the hardware and software behind electrification and automation. Its business spans low- and medium-voltage electrical products, switchgear and building systems (Electrification), electric motors, drives and traction (Motion), and control systems, measurement and industrial software (Process Automation). Historically it also ran a Robotics division, but in 2025 ABB agreed to divest that unit to SoftBank Group for an enterprise value of roughly $5.4 billion, moving the company to three reporting business areas. ABB reports in US dollars, sells into utilities, data centers, manufacturers, transport and infrastructure customers worldwide, and competes with the likes of Siemens, Schneider Electric and Rockwell Automation.
What does Rockwell Automation (ROK) do?
Rockwell Automation (ROK) is one of the largest pure-play industrial automation and digital transformation companies in the world. It provides the hardware, software, and services that factories and industrial facilities use to run, monitor, and optimize their operations: programmable logic controllers, drives, motor control, sensors, industrial networking, and the Allen-Bradley and FactoryTalk product families that are standards in many North American plants. Rockwell organizes its business around Intelligent Devices, Software and Control, and Lifecycle Services, and increasingly pairs its installed base of automation hardware with software, analytics, and recurring services. A long partnership with software firms and its acquisitions in areas like manufacturing-execution software, cybersecurity, and information solutions position it to sell connected, data-driven factory systems, not just discrete controllers. Founded in 1903 and headquartered in Milwaukee, Wisconsin, Rockwell is an S&P 500 industrial that benefits from secular trends in reshoring, factory modernization, and the digitization of manufacturing, while remaining tied to the capital-spending cycles of its industrial customers.
ABB vs ROK: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- ABB drivers: Electrification and grid demand; Automation and energy-efficient motion.
- ROK drivers: Installed base and switching costs; Software, recurring revenue, and analytics.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: ABB is a cyclical industrial whose orders and revenue track global capital spending, so a slowdown in manufacturing, construction or utility investment would pressure growth. For ROK, rockwell's results are tied to industrial and manufacturing capital-spending cycles, so demand can soften in downturns or when customers delay projects, and orders can be lumpy.
ABB or ROK: which should you pick?
ABB vs ROK: the full fundamentals
ABB. ABB posted a record 2025, with revenue up about 9% to roughly $33 billion, orders up about 17% near $37 billion, and net income up about 20% to around $4.7 billion. The stock trades at a premium, with a trailing P/E in the mid-30s and a forward multiple near 30, reflecting strong returns on capital (ROE near 29%) and secular demand. Figures are approximate and drawn from ABB's FY2025 disclosures and market data as of mid-2026.
ROK. Rockwell typically trades at a premium multiple relative to the broader industrials group, reflecting its pure-play automation focus, strong installed-base moat, and growing software mix. The valuation embeds expectations for factory modernization and reshoring; multiple compression risk rises if the industrial capital-spending cycle weakens or order growth disappoints. Figures are approximate and move with results and price; verify current revenue, margins, and yield.
Headline figures (approximate, JULY 2026): ABB shows revenue (fy2025) ~$33.2B, orders (fy2025) ~$36.8B, net income (fy2025) ~$4.7B, operational ebita margin ~19%; ROK shows revenue (ttm) ~$8 billion (verify), operating margin ~ high teens to ~20% segment margins (verify), profitability Consistently profitable, p/e (ttm) ~25x to ~30x, varies (verify).
The bottom line: ABB vs ROK
ABB and ROK are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined ABB and ROK exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between ABB and ROK?
+
ABB Ltd is a global technology company headquartered in Zurich, Switzerland, that builds the hardware and software behind electrification and automation. Rockwell Automation (ROK) is one of the largest pure-play industrial automation and digital transformation companies in the world. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is ABB or ROK the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, ABB or ROK?
+
A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both ABB and ROK?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of ABB vs ROK?
+
ABB: ABB is a cyclical industrial whose orders and revenue track global capital spending, so a slowdown in manufacturing, construction or utility investment would pressure growth. As a Swiss company reporting in US dollars with sales across many currencies, results are exposed to foreign-exchange swings and to macro shocks in Europe, China and the Americas. The shares trade at a premium valuation that assumes continued margin strength and secular demand, leaving limited downside cushion if growth disappoints. Execution risk around the Robotics divestiture, supply-chain disruption, and intense competition from Siemens, Schneider Electric and others could all weigh on returns. Tariffs, geopolitical tension and project delays in large infrastructure and process customers add further uncertainty. ROK: Rockwell's results are tied to industrial and manufacturing capital-spending cycles, so demand can soften in downturns or when customers delay projects, and orders can be lumpy. It competes with large global automation rivals like Siemens, Schneider Electric, ABB, and Emerson, several of which have broader geographic and product breadth. Exposure to specific end markets (autos, semiconductors, food and beverage, energy) introduces concentration and cyclicality. Supply-chain disruptions and component availability have affected lead times in the past. The stock often trades at a premium multiple for an industrial, so disappointing orders or margins can pressure the valuation.
