A high-ROIC business that can't reinvest its profits is a good business, not a compounder. The distinction matters enormously for long-run returns. A company earning 25% ROIC on a static, saturated market can only return that cash to shareholders — a fine but limited outcome. A company earning 25% ROIC with a long runway to reinvest at similar rates compounds that return year after year, and the stock price eventually has to follow. This post is about screening for that specific combination — not ROIC alone, which is already covered in depth in the ROIC investing guide, and not general business quality, which the quality investing screener addresses more broadly.

The compounder equation
The thesis, popularised by investors like Terry Smith and rooted in classic Warren Buffett letters on capital allocation, comes down to three conditions that all need to hold simultaneously:
1. High returns on capital — the business earns well above its cost of capital on money already invested (see ROIC investing for the full mechanics of this metric).
2. A genuine reinvestment opportunity — the business has somewhere to put incremental capital that earns a similar high return, not just a market for its existing products at existing scale.
3. Enough runway for this to continue for years, not quarters — a large enough addressable market, or enough adjacent opportunities, that the reinvestment loop doesn't hit a ceiling within a short time horizon.
Miss any one of the three and the compounding stops. High ROIC with no reinvestment opportunity just produces a cash-generative but stagnant business (still investable, just not a compounder). Reinvestment without high returns on that capital destroys value rather than compounding it — growth for its own sake. And a short runway means the compounding period, however attractive, ends quickly.
Screening for the combination, not just ROIC
A screen for ROIC alone produces a mixed list: mature, high-return businesses with nowhere left to grow sit alongside genuine compounders with years of reinvestment ahead of them. The additional filters that separate the two:
Revenue growth as a proxy for reinvestment opportunity
If a company is both earning high ROIC and growing revenue at an above-average rate, it's evidence the reinvestment opportunity is real, not theoretical — capital is actually being deployed and it's working. See revenue growth screening for how to evaluate this in isolation; here it's used specifically as corroborating evidence for the compounding thesis.
Stability of the ROIC over time, not a single-year snapshot
A single high-ROIC year can reflect a cyclical peak rather than a durable structural advantage. Checking ROIC across a 3–5 year window — and confirming it hasn't been declining — is a better filter than a single trailing-twelve-month figure.
Reinvestment rate
The proportion of operating profit being retained and reinvested in the business (rather than paid out as dividends or spent on buybacks) indicates whether management is actively pursuing the reinvestment opportunity or has already concluded the runway is limited and is choosing to return cash instead. Neither choice is wrong — but a business paying out the large majority of its profits has, by its own management's revealed preference, signalled it isn't a compounder in the classic sense, whatever its ROIC looks like.
Building the screen
Core compounder screen:
| Filter | Value |
|---|---|
| ROIC | > 15% |
| ROIC (3yr trend) | Stable or improving |
| Revenue growth (3yr CAGR) | > 8% |
| Operating margin | > 12%, stable or expanding |
| Net Debt/EBITDA | < 2.0 |
| Sort by | ROIC descending, then revenue growth descending |
Higher-conviction, narrower screen (fewer, more selective candidates):
- ROIC > 20%
- Revenue growth (3yr CAGR) > 12%
- Operating margin expanding YoY
- Net Debt/EBITDA < 1.5
- Sort by: revenue growth descending
The second screen trades breadth for conviction — expect a short list, but one where both halves of the compounder equation (high current returns, evidence of a real and growing reinvestment opportunity) are both strongly present rather than just one.
Where compounders tend to cluster in Europe
Branded consumer and luxury (see European luxury stocks): high gross margins, pricing power, and — for the strongest names — decades of runway through geographic expansion and category extension.
Specialised industrial technology: niche European industrial and automation businesses (common across German Mittelstand and Swiss precision engineering) that dominate narrow global markets and can reinvest in adjacent applications of the same core technology.
Healthcare and medtech with recurring consumables: businesses selling durable equipment plus high-margin, recurring consumables tend to combine strong ROIC with a long reinvestment runway as the installed base grows.
Founder-led software and platform businesses: where high insider ownership (see insider ownership screening) often correlates with disciplined, long-horizon capital allocation rather than short-term profit harvesting.
Common mistakes when screening for compounders
Confusing a high-ROIC business with a compounder: The ROIC condition alone is necessary but not sufficient. Without evidence of a genuine, ongoing reinvestment opportunity — revenue growth, expanding operating footprint, adjacent market entry — a high-ROIC business is simply a good cash generator, which is a different (and shorter) thesis.
Ignoring the trend in ROIC: A single strong year can be cyclical rather than structural. Checking stability or improvement over a multi-year window is a meaningfully better filter than a trailing-twelve-month snapshot.
Overpaying for the compounding: The market often recognises genuine compounders and prices them at a premium. Screening for the fundamental combination is only half the process — a valuation check (against the company's own history, or peers with a similar growth/ROIC profile) still matters before acting on the screen.
Assuming past reinvestment success guarantees future runway: A business that has compounded successfully for a decade can still run out of genuine reinvestment opportunities. Revenue growth deceleration alongside still-high ROIC is an early signal that the runway may be shortening, even if the historical numbers still look excellent.
Bottom line
Screening for compounders means screening for the combination of high returns on capital, evidence of a genuine reinvestment opportunity, and enough runway for the compounding to continue — not any one of those conditions in isolation. ROIC alone surfaces good businesses; ROIC paired with sustained, above-average revenue growth and a stable-to-expanding operating margin surfaces the narrower list where the reinvestment loop is demonstrably still working.
Frequently asked questions
What's the difference between a compounder and a quality stock?
Every compounder is a quality business, but not every quality business is a compounder. A quality screen (stable margins, reasonable leverage, decent returns on capital) can include mature, low-growth businesses that are well-run but have limited room to reinvest profitably. A compounder specifically requires the additional condition of a genuine, ongoing reinvestment opportunity at similarly high returns — evidenced by sustained above-average revenue growth alongside high ROIC.
What ROIC level is needed to qualify as a compounder?
There's no strict universal threshold, but ROIC consistently above 15% is a common starting point, with the strongest compounder candidates typically showing ROIC above 20%. The level matters less in isolation than its stability over a multi-year window and whether it's paired with genuine revenue growth evidencing a real reinvestment opportunity.
Can a company be a compounder without high revenue growth?
It's uncommon by the classic definition. Revenue growth is the clearest observable evidence that a company is finding places to profitably deploy incremental capital. A high-ROIC business with flat or declining revenue is more accurately described as a mature cash generator — still potentially a good investment, but a different thesis with a shorter compounding runway.
Are compounders overvalued by default?
Not by default, but the market often does recognise strong compounding businesses and prices them at a premium multiple relative to the broader market. Screening identifies the fundamental combination; a separate valuation check against the company's own historical multiple range or comparable peers is still necessary before concluding the current price offers an attractive entry point.
