FANUY vs ROK: How Fanuc and Rockwell Automation Compare (2026)
Last updated July 2026
Short answer
ROK is the larger of the two ($50.71B market cap): the incumbent the market prices for continued execution (31.15x forward earnings, beta 1.54). FANUY is the smaller challenger ($39.29B), priced similarly on forward earnings (31.42x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
FANUY vs ROK: the tie-breaker metrics
Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | FANUY | ROK | What it tells you |
|---|---|---|---|
| Market cap | $39.29B | $50.71B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 31.42 | 31.15 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 38.98 | 47.42 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.94 | 1.54 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 53% of range | 78% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 3.45 | 14.40 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how FANUY 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. FANUY 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 FANUY 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.

What does Fanuc (FANUY) do?
Fanuc is a Japanese manufacturer of industrial robots, CNC controls and factory automation systems, and is one of the largest robot makers in the world by installed base.
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.
FANUY 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.
- FANUY drivers: CNC controls are the hidden franchise; Robot installed base and service.
- 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: Fanuc's revenue is heavily exposed to Chinese manufacturing capital spending and to the global machine-tool cycle, both of which swing sharply. 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.
FANUY or ROK: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick FANUY if you believe its drivers more; ROK if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the FANUY and ROK guides.
FANUY vs ROK: the full fundamentals
FANUY. Fanuc is a high-quality franchise in a deeply cyclical end market, and its results tend to lead or track Chinese and global manufacturing investment. Verify current order intake, which is the most informative near-term metric.
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.

FAQ
What is the difference between FANUY and ROK?
+
Fanuc is a Japanese manufacturer of industrial robots, CNC controls and factory automation systems, and is one of the largest robot makers in the world by installed base. 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 FANUY or ROK the better stock?
+
Neither is universally better. ROK is the larger incumbent; FANUY is the smaller challenger and looks pricier on forward earnings. 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, FANUY or ROK?
+
On forward P/E (as of July 2026), FANUY trades at 31.42x and ROK at 31.15x, so ROK is the cheaper of the two on next year's expected earnings. 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 FANUY 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 FANUY vs ROK?
+
FANUY: Fanuc's revenue is heavily exposed to Chinese manufacturing capital spending and to the global machine-tool cycle, both of which swing sharply. It is a Japanese company, so US investors hold an ADR exposed to yen movements. Competition from Chinese domestic robot makers has intensified and is taking share at the lower end. Automotive and electronics customers drive a large share of orders, concentrating the cycle. 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.
