DOV vs IR: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
DOV and IR are similarly sized, but DOV trades noticeably cheaper on forward earnings (17.59x vs 21.61x): the market is paying up for IR's profile and pricing DOV more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
DOV vs IR: the tie-breaker metrics
Same yardstick, side by side (as of August 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 | DOV | IR | What it tells you |
|---|---|---|---|
| Forward P/E | 17.59 | 21.61 | 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 | 24.74 | 34.45 | 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 | 1.16 | 1.17 | 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 | 58% of range | 47% 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 | 3.58 | 3.21 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: DOV is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how DOV and IR 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. DOV and IR 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 DOV and IR 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 Dover Corporation (DOV) do?
Dover Corporation is a diversified global manufacturer of a broad range of specialized industrial products and equipment. It operates through five segments: Engineered Products (industrial winches, aerospace and defense components, vehicle service, and waste-handling equipment), Clean Energy and Fueling (fuel dispensers, systems for cleaner energy and alternative fuels), Imaging and Identification (marking, coding, and serialization for consumer and industrial goods), Pumps and Process Solutions (pumps, compressors, and precision components for fluid handling and biopharma), and Climate and Sustainability Technologies (commercial refrigeration, CO2 systems, heat exchangers, and thermal connectors used in data-center cooling). Dover makes money by selling this hardware plus recurring aftermarket parts, consumables, and service, and it has steadily reshaped its portfolio toward higher-margin, faster-growing niches. It is headquartered in Downers Grove, Illinois.
What does Ingersoll Rand (IR) do?
Ingersoll Rand is a global industrial-technology company built around mission-critical air, fluid, gas, and medical technologies. It operates through two segments: Industrial Technologies and Services, which sells air compressors, vacuum and blower systems, air treatment, power tools, and lifting equipment; and Precision and Science Technologies, which makes highly engineered pumps and fluid-management systems for medical, life-science, and specialty industrial uses. The company was formed in 2020 when Gardner Denver merged with the Industrial segment of the old Ingersoll-Rand, and it sells under brands such as Ingersoll Rand, Gardner Denver, Nash, and many acquired niche names. A large share of revenue comes from aftermarket parts, consumables, and service on a big installed base, which makes results steadier than a pure equipment maker. Ingersoll Rand is headquartered in Davidson, North Carolina.
DOV vs IR: 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.
- DOV drivers: Secular growth pockets inside a diversified base; Record bookings and margin expansion.
- IR drivers: IRX operating system and margins; Disciplined bolt-on M&A.
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: Dover's end markets are cyclical and tied to industrial capital spending, energy and fueling investment, and the global economy, so a downturn can slow orders and revenue. For IR, ingersoll Rand's end markets are cyclical and tied to global industrial capital spending, manufacturing activity, and specific verticals like energy and semiconductors, so downturns can slow orders and short-cycle revenue.
DOV or IR: which should you pick?
DOV vs IR: the full fundamentals
DOV. Dover trades at a mid-teens to high-teens forward earnings multiple, roughly in line with quality diversified industrials, reflecting steady mid-single-digit organic growth, expanding margins, and secular exposure through clean energy, CO2 refrigeration, and data-center cooling. The very low dividend yield near 1 percent understates the appeal of its record 69-year increase streak, which is anchored by a conservative payout ratio and strong free cash flow. The market weighs its secular growth pockets and cash-return record against cyclical end markets and acquisition risk.
IR. Ingersoll Rand trades at a premium to the average industrial, reflecting its high aftermarket and mission-critical mix, consistent margin expansion under IRX, and disciplined free-cash-flow-funded M&A. Q1 2026 revenue was about $1.85 billion, up roughly 8 percent, with adjusted EPS near $0.77, and management maintained full-year guidance of about 2.5 to 4.5 percent revenue growth and roughly $3.45 to $3.57 adjusted EPS. The dividend is nominal because the company prioritizes reinvestment and acquisitions over payouts.
Headline figures (approximate, July 2026): DOV shows revenue (ttm) ~$8.1 billion, q1 2026 revenue ~$2.05 billion, up ~10%, segment margin ~22%, 2026 adjusted eps guide ~$10.45 to $10.65; IR shows revenue (2025) ~$7.65 billion, revenue (q1 2026) ~$1.85 billion, up ~8% YoY, 2026 revenue growth guide ~2.5% to 4.5%, 2026 adjusted eps guide ~$3.45 to $3.57.
The bottom line: DOV vs IR
DOV and IR 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 DOV and IR exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between DOV and IR?
+
Dover Corporation is a diversified global manufacturer of a broad range of specialized industrial products and equipment. Ingersoll Rand is a global industrial-technology company built around mission-critical air, fluid, gas, and medical technologies. 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 DOV or IR 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, DOV or IR?
+
On forward P/E (as of August 2026), DOV trades at 17.59x and IR at 21.61x, so DOV 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 DOV and IR?
+
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 DOV vs IR?
+
DOV: Dover's end markets are cyclical and tied to industrial capital spending, energy and fueling investment, and the global economy, so a downturn can slow orders and revenue. Its acquisition-driven strategy carries integration, execution, and valuation risk, and goodwill from deals could be impaired if results disappoint. Foreign-exchange swings, supply-chain disruptions, tariffs, and input-cost inflation can pressure margins. Competition across its niches is intense, and some segments depend on specific regulatory or refrigerant-transition timelines that can shift. The stock can be volatile around macro cycles and earnings, and its premium-to-history valuation leaves less margin for error. IR: Ingersoll Rand's end markets are cyclical and tied to global industrial capital spending, manufacturing activity, and specific verticals like energy and semiconductors, so downturns can slow orders and short-cycle revenue. The serial-acquisition strategy carries integration, execution, and valuation risk, and heavy reliance on M&A means growth can disappoint if the deal pipeline slows or purchase multiples rise. Foreign-exchange swings, tariffs, and supply-chain disruptions can pressure results given the global footprint. Competition across compression and flow control is intense, including from larger and lower-cost rivals. The stock trades at a premium to the average industrial, so any slowdown in margin gains or capital deployment can weigh on the multiple.
