What the best stocks do with their cash
2026-07-03 · By Lubin Danilo, founder of Lubin Investment
Capital allocation is the decision of what to do with the cash left after the bills are paid: reinvest it, buy back shares, pay down debt, or distribute it as dividends. Roper acquires dozens of niche companies, ASML buys back its own stock, Realty Income pays out almost all its cash every month by legal obligation. None of these strategies is better in itself: the right allocation fits the business model.
- Capital allocation means choosing what to do with the cash a business generates: reinvest it, buy back shares, pay down debt, or pay a dividend.
- Roper Technologies reinvests its cash into dozens of niche acquisitions every year instead of paying it out.
- ASML favors share buybacks and heavy R&D spending to defend its monopoly, rather than a generous dividend.
- Realty Income pays out almost all of its cash every month: US law on REITs requires it.
- There's no single right capital allocation: the right one is the one that fits the company's business model and reinvestment opportunities.
What is capital allocation, exactly?
Every year, a profitable company generates free cash flow: the cash left over after payroll, taxes, maintenance spending and debt interest are paid. What separates a great manager from a mediocre one is what happens next. That cash can be reinvested in growth (new plants, acquisitions, research), used to pay down debt, spent buying back the company's own shares on the market, or paid out as a dividend. That's capital allocation: how management chooses to deploy every dollar of available cash.
On my site, I score companies on 10 financial quality criteria, separate from their stock price. Two of them earn the maximum score while taking almost opposite paths, Roper Technologies and ASML, while a third, Realty Income, earns a more modest score for a specific reason I detail below. Looking at how each one uses its cash teaches you more about management quality than any single ratio ever could.
Roper Technologies: the disciplined collector of small cash machines
Roper Technologies (ROP) is what's called a serial acquirer: a company whose core strategy is to continuously buy other businesses rather than grow purely on its own. It targets specialized software in niche markets (medical practice management, legal software, food logistics platforms) where it often becomes the only serious vendor left standing. In 2025, it deployed roughly 3.3 billion dollars into new acquisitions.
The math behind Roper is straightforward: its cash return on capital employed (Cash ROCE, which measures how much cash a company generates for every dollar of capital tied up in the business) comes out at 25.8% in our data, well above its cost of debt. As long as Roper keeps finding targets at that level of profitability, every dollar reinvested into an acquisition is worth more than the same dollar paid out as a dividend. Its free cash flow margin (the share of revenue that turns into usable cash) stands at 29.9%, and the stock currently trades at 15.7 times that annual cash figure, a multiple I consider reasonable given its quality.
The flip side: Roper funds part of its acquisitions with debt. Our leverage criterion flags a warning, with a net debt to free cash flow ratio of 4.16, meaning it would take a bit over four years of cash flow to pay off all its debt. That's not alarming as long as the acquisitions return more than they cost to finance, but it's the price of nonstop external growth. See the full breakdown on the Roper Technologies analysis page.
ASML: buying back its own stock instead of paying a generous dividend
ASML (ASML.AS) builds the extreme ultraviolet (EUV) lithography machines, the only technology on earth capable of etching the most advanced computer chips. No competitor has managed to build one: ASML effectively holds a monopoly on this segment. The result is formidable pricing power and an outsized cash return on capital employed, 116.7% in our data, a figure that mostly reflects how little capital the business needs relative to the cash it throws off.
Instead of paying a large dividend, ASML directs its cash toward two priorities: research and development (between 15% and 18% of revenue every year, to keep a decade-long technology lead) and share buybacks, running at roughly 10,000 shares repurchased per day under its 2026-2028 program. A buyback is when a company purchases its own shares on the open market and retires them: fewer shares remain outstanding, so each remaining share represents a slightly bigger slice of the company. ASML's share count has been shrinking by 0.77% per year as a result.
The thing to watch is the price paid for those buybacks. ASML currently trades at 51.6 times its annual free cash flow, a multiple that fails our valuation criterion (I generally look for something below 25 times). Buying back shares at a rich price isn't free: every dollar spent repurchasing an expensive share returns less than a dollar reinvested into a cheap acquisition.

Realty Income: a monthly dividend as a legal obligation, not a choice
Realty Income (O) calls itself The Monthly Dividend Company: it has paid a dividend every single month for more than 30 years straight. But here, the generosity isn't really a management choice. Realty Income is a REIT (real estate investment trust, a publicly traded landlord), a status that legally requires it to distribute at least 90% of its taxable income to shareholders each year in the US in order to avoid paying corporate income tax.
That legal constraint changes how you should read its numbers. Its free cash flow margin comes out at 68.4% in our data, a figure that looks extraordinary but mostly reflects how rental real estate accounting works (few operating expenses once a building is leased out). Because it keeps almost nothing to fund its own growth, Realty Income has to regularly issue new shares and new debt to buy more properties. Its share count has grown by 15.11% a year in our tracking, and its net debt represents 7.26 years of generated cash.
That's a big part of why Realty Income scores 6 out of 10 in our quality grid, well below the perfect 10 out of 10 for Roper and ASML. Two criteria, designed to spot good capital discipline at an industrial or software company (a stable share count, debt that pays down quickly), almost mechanically penalize a growing REIT, whose dilution and leverage stem directly from its legal status rather than poor management. Two other red flags, though, aren't explained away by REIT law and deserve real attention: its cash flow per share growth has stalled at 1.1% a year, and its margins have been slightly compressing. It's a good example of the limits of a single scoring grid: it's a starting point, not a final verdict. See the full breakdown on the Realty Income analysis page.
Three strategies, side by side
Here's how the three approaches stack up against each other.
| Company | Main strategy | What it means for you as a shareholder | Key figure (our data) |
|---|---|---|---|
| Roper Technologies (ROP) | Disciplined serial acquirer: reinvests in niche acquisitions | Your cash doesn't come back to you, it funds the next high-return acquisition | Cash ROCE of 25.8%; about 3.3 billion dollars in acquisitions in 2025 |
| ASML (ASML.AS) | Large share buybacks and heavy R&D spending | Your ownership stake grows mechanically, with no large dividend | Share count down 0.77% a year; R&D at 15-18% of revenue |
| Realty Income (O) | Near full cash distribution (legal REIT requirement) | You get paid a dividend every month, but growth comes from new shares and debt | Legally required to distribute at least 90% of taxable income; share count up 15.11% a year |
What a capital allocation choice reveals about management
A share buyback is only good news if the price paid is reasonable. A manager who buys back stock at the top of a cycle destroys value for the shareholders who remain, exactly as if they'd overpaid for any other asset. Conversely, a manager who buys back aggressively when the market is fearful and the stock is cheap creates value for everyone still holding shares. What matters isn't how much is spent on buybacks, it's the price paid.
The same logic applies to acquisitions. Roper's serial acquirer strategy only works because its return on invested capital stays well above its cost of debt. A serial acquirer that overpays for targets, or borrows at a rate higher than its return, would destroy value with every deal, even as group revenue keeps climbing. Growth isn't automatically good news: it still has to earn more than it costs.
Realty Income isn't playing that game at all: its whole business as a REIT is to keep almost nothing. The right question for this type of company isn't 'is it buying back enough shares?' but 'is it buying new properties at a price that stays profitable, funded by reasonable debt?' It's a different lens, fitted to a different business model.
How I use this in my own method
This is exactly the kind of nuance I try to surface with my method: the score out of 10 tells you whether the business is solid, the valuation (like the price-to-free-cash-flow ratio, the stock price divided by the cash the business generates) tells you whether the price is reasonable, but understanding how management allocates its capital is often what separates a good investment decision from a great one. I always look at this before adding a stock to my watchlist.
FAQ
What exactly is capital allocation?
It's how a company's management decides to use the cash available once ongoing expenses are paid: reinvest it into growth (plants, research, acquisitions), pay down debt, buy back shares, or pay a dividend. The choice reveals a lot about management quality.
Is a share buyback always good for shareholders?
No. A buyback only benefits shareholders if it's done at a reasonable price. Buying back expensive shares at the top of a cycle destroys value for remaining shareholders, even if the move looks generous on the surface.
Why doesn't Realty Income get the same score as Roper or ASML?
Realty Income scores 6 out of 10 in our grid versus 10 out of 10 for the other two, largely because its REIT status forces it to distribute almost all its cash and fund growth through new shares and debt. Our criteria for a stable share count and controlled debt, built for industrial or software companies, read this legal constraint as a weakness even though it stems from the business model itself.
What is a serial acquirer?
It's a company whose growth strategy relies on repeatedly buying other businesses rather than growing organically alone. Roper Technologies is a textbook example: it acquires dozens of niche software businesses every year and folds them into the group.
Should you prefer a stock with a big dividend over one that reinvests all its cash?
It depends entirely on the return the company can generate on that reinvested cash. If it can find projects that earn more than its cost of capital, reinvesting creates more value than a dividend. If it's run out of profitable opportunities, paying out the cash becomes the better decision. There's no universal rule, only a fit to check case by case.

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
