ASH vs WDFC: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
ASH and WDFC are similarly sized, but ASH trades noticeably cheaper on forward earnings (16.58x vs 30.91x): the market is paying up for WDFC's profile and pricing ASH 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.
ASH vs WDFC: the tie-breaker metrics
Same yardstick, side by side (as of October 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 | ASH | WDFC | What it tells you |
|---|---|---|---|
| Market cap | $3.26B | $2.69B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 16.58 | 30.91 | 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 | 45.63 | 30.41 | 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 | 0.40 | 0.26 | 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 | 77% of range | 20% 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 | 1.74 | 9.65 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: ASH 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 ASH and WDFC 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. ASH and WDFC 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 ASH and WDFC 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 Ashland (ASH) do?
Ashland Inc. is a Wilmington, Delaware based global specialty chemicals company that operates through four segments: Life Sciences (pharma excipients and nutrition), Personal Care (skin, hair, and biofunctionals), Specialty Additives (cellulosic and rheology modifiers used in coatings, construction, and energy), and Intermediates. The company sells performance ingredients rather than commodity chemicals, competing on formulation know-how, regulatory support, and security of supply into consumer and healthcare end markets.
What does WD-40 Company (WDFC) do?
WD-40 Company makes multi-purpose maintenance products (the flagship WD-40 spray, the WD-40 Specialist line of silicone lubricants, white lithium grease and contact cleaners, plus the 3-IN-ONE brand) alongside a smaller homecare and cleaning products group. Roughly 97% of revenue now comes from its core maintenance products, sold in more than 175 countries and produced through a capital-light, outsourced-manufacturing model that lets the company focus on brand, formulation and distribution.
ASH vs WDFC: 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.
- ASH drivers: Specialty additives and volume recovery; Activist campaign and possible sale.
- WDFC drivers: Core maintenance-product strength; Pricing power and margin recovery.
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: Ashland is exposed to cyclical demand in coatings, construction, and energy, and fiscal 2025 showed how destocking can sharply cut volumes and earnings. For WDFC, wD-40 depends heavily on a single flagship brand, so any reputational, formulation or regulatory issue with that product would be outsized.
ASH or WDFC: which should you pick?
ASH vs WDFC: the full fundamentals
ASH. Trailing GAAP earnings are still depressed by restructuring, so the stock is valued on EBITDA and forward earnings: about 11.9x EV/EBITDA and roughly 17x analysts' fiscal 2027 EPS estimate of $4.29. The 47% one-year rise has pushed the dividend yield down to about 2.3%. The November 3 report (consensus EPS about $1.28) will be the first full-year read since the buyback doubled.
WDFC. At $200.56 on October 16, 2026, WDFC trades near 30x trailing earnings with a dividend yield of about 2%, cheaper than in July 2026 when the stock was near $246 but still a premium multiple for a mature category. Forward EPS estimates (about $6.47 for fiscal 2027) sit slightly below trailing EPS of $6.58, so the multiple rests on durability rather than on expected earnings growth.
Headline figures (approximate, October 2026): ASH shows revenue (ttm) ~$1.84 billion; fiscal Q3 2026 ~$497 million, up ~7%, fiscal q3 2026 eps $1.02 adjusted vs ~$0.98 consensus, margins (ttm) ~33% gross, ~11.5% operating, ~3% net, market cap ~$3.3 billion at ~$72 per share (Oct 16, 2026); WDFC shows revenue (ttm) ~$675M; Q3 FY2026 (to May 31) ~$195M, up ~24% YoY, margins (ttm) Gross ~56%, operating ~21%, net ~13%, net income (ttm) ~$89M; Q3 FY2026 EPS $2.24 vs $1.57 expected, p/e ~30x trailing, ~31x forward.

FAQ
What is the difference between ASH and WDFC?
+
Ashland Inc. WD-40 Company makes multi-purpose maintenance products (the flagship WD-40 spray, the WD-40 Specialist line of silicone lubricants, white lithium grease and contact cleaners, plus the 3-IN-ONE brand) alongside a smaller homecare and cleaning products group. 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 ASH or WDFC 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, ASH or WDFC?
+
On forward P/E (as of October 2026), ASH trades at 16.58x and WDFC at 30.91x, so ASH 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 ASH and WDFC?
+
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 ASH vs WDFC?
+
ASH: Ashland is exposed to cyclical demand in coatings, construction, and energy, and fiscal 2025 showed how destocking can sharply cut volumes and earnings. The large reported net loss reflected impairments and divestiture effects that signal ongoing portfolio and asset-value pressure, and trailing GAAP net income is only about $75 million, which is why the trailing P/E is near 46x even though the forward P/E is about 17x. The dividend payout runs above 100% of trailing GAAP earnings, covered by cash flow rather than reported profit. The activist thesis is uncertain: a sale may not materialize, and a proxy fight could create disruption. Debt of about $1.48 billion against roughly $440 million of cash, input-cost inflation, currency swings, the Hopewell ramp, and the modest scale that activists criticize all weigh on the standalone case. After a 47% one-year gain, analysts' mean target of about $80 sits only modestly above the price, and UBS trimmed its target to $80 from $83 in October 2026. WDFC: WD-40 depends heavily on a single flagship brand, so any reputational, formulation or regulatory issue with that product would be outsized. GAAP EPS fell about 32% year over year in Q2 fiscal 2026, showing that input costs, tax items and one-off charges can pressure reported profit even when sales grow. The stock carries a premium valuation (about 30x trailing earnings and 31x forward as of October 2026), which leaves little room for disappointment if growth slows; analysts expect fiscal fourth-quarter EPS of about $1.13, down about 28% from a year earlier, after the strong third quarter. The shares fell about 16% over the three months to mid-October 2026, from a 52-week high of $298.90. A CFO transition, with Keith Stauffer hired in September 2026, adds a period of change in the finance function. It also faces currency swings on international sales, competition from lower-priced lubricants, and the slow-growth nature of a mature maintenance-products category.
