The one quality criterion mega-cap stocks miss most

Among eight companies worth more than 200 billion dollars that my quality filter ranks among the world's best, one criterion out of ten resists almost all of them: how long it takes to turn a sale into cash actually sitting in the bank. Here is why size makes this specific point harder to check.
Eight giants, a live-checked score
My quality filter runs every company through ten objective financial criteria (profitability, sales and cash growth, share count discipline, debt, margins) to produce a score out of 10, completely independent of the stock's price. Among the 500 best scores in my universe, only a handful of companies clear 200 billion dollars in market value. I wanted to know whether quality still holds at that scale, or whether sheer size is doing the work instead.
Eight names stand out this month: Nvidia, Taiwan Semiconductor, Mastercard, Netflix, Novartis, GE Vernova, Arista Networks and SAP. I checked each one live on its own analysis page rather than trusting my general ranking, which can show a slightly stale score compared with the latest data refresh. As of August 10, 2026, the result is a score ranging from 7 to 10 out of 10, almost never a perfect ten.
| Stock | Market cap | Quality score /10 | Main weak point |
|---|---|---|---|
| Nvidia (NVDA) | ~$5.4 trillion | 9/10 | Cash conversion at 70% of accounting profit |
| Taiwan Semiconductor (TSM) | ~$2.15 trillion | 8/10 | Cash conversion only 46% plus heavy capex |
| Mastercard (MA) | ~$510 billion | 10/10 | None, the only perfect score in the group |
| Netflix (NFLX) | ~$320 billion | 9/10 | Collection time not measurable, cash at 84% |
| Novartis (NVS) | ~$300 billion | 7/10 | Debt (6.5 years of cash), collection time not measurable |
| GE Vernova (GEV) | ~$270 billion | 9/10 | Collection time of 127 days |
| Arista Networks (ANET) | ~$240 billion | 9/10 | Collection time of 255 days |
| SAP | ~$215 billion | 8/10 | Sales growth below 10% a year (7.5%) |
The one criterion that spares no one
Out of the ten criteria, exactly one is passed by none of the eight companies: net cash collection time, the delay between the moment a company makes a sale and the moment the cash is actually sitting in its bank account. I have already broken this mechanic down in a dedicated article: the shorter this delay, the less cash a company has to tie up just to keep running; some businesses, like airlines or franchisors, even collect before they spend.
At this scale, two forces work against them. The first is customer size: when you sell to other giants (data center operators, governments, manufacturers), the balance of power over payment terms flips, and the buyer sets the rules. The second is the pace of investment: a company building factories or data centers spends the cash today for revenue that will only show up years later. Taiwan Semiconductor illustrates this second point well. The Taiwanese foundry raised its 2026 capital spending guidance to 60 to 64 billion dollars in the second quarter, up from 52 to 56 billion announced just months earlier, according to trade press coverage. That money leaves the bank years before the corresponding chips generate a single dollar of sales, and it shows up directly in the numbers: only 46% of its accounting profit turns into real cash this year, one of the lowest rates in the group.
| Criterion | Passed by (out of 8 mega-caps) |
|---|---|
| Net margin | 8/8 |
| Share count discipline | 8/8 |
| Cash profitability | 8/8 |
| Expanding margins | 8/8 |
| Free cash flow per share growth | 7/8 |
| Debt under control | 7/8 |
| Sales growth | 5/8 |
| Return on invested capital | 5/8 |
| Profit to cash conversion | 4/8 |
| Net cash collection time | 0/8 |
The overall picture is clear. Profitability, share count discipline and margin expansion almost never trip these companies up, and that is expected: you do not become a 200 billion dollar company without it. What separates them is everything tied to short term cash: converting it fast, and collecting it fast. Two mechanics that size makes harder, not easier.
Mastercard, the exception that proves the rule
Only one company in the group earns the maximum score: Mastercard. Its second quarter of 2026 shows exactly why it dodges the trap the others fall into: revenue up 14% to 9.3 billion dollars, net income up 19% to 4.4 billion, and 5.7 billion dollars returned to shareholders through buybacks and dividends in that single quarter, according to its earnings release filed with the US regulator. Mastercard does not manufacture anything and, unlike American Express, does not lend money to its cardholders: it simply routes information between banks and charges a toll on every transaction. No factories, no inventory, no receivables stretching out for months.
That is the exact opposite of Nvidia or Taiwan Semiconductor, which have to advance billions into factories and chips long before seeing any of that cash come back. A digital toll booth and a semiconductor production line do not play in the same cash collection league, even though both fully deserve their place among my best scores.
Missing this one criterion does not make these companies bad investments. The quality score judges the business, not the price, and a 7, 8 or 9 out of 10 remains a score the overwhelming majority of public companies never reach. It simply says that past 200 billion dollars, there is a near mechanical friction on short term cash that even the best management cannot fully erase. You can check where a specific company stands in the full ranking of perfect scores, and see how all ten criteria work in my complete methodology.
FAQ
What is net cash collection time?
The time between the moment a company makes a sale and the moment the corresponding cash is actually sitting in its bank account. The shorter it is, the less cash the company has to tie up to operate. I explain the mechanic in detail, with more examples, in my dedicated article.
Does missing this criterion make a stock one to avoid?
No. It is one criterion out of ten, not a verdict on its own. Nvidia, Netflix and Mastercard miss or barely pass this specific point and remain very high quality businesses on the other nine. My filter scores business quality separately from the stock's price.
Why does size make this criterion harder?
Two main reasons: the balance of power with large customers who impose long payment terms, and the pace of investment. A company building factories or data centers spends the cash years before collecting the corresponding revenue.
Can this ranking of the largest companies change?
Yes, often. Scores are recalculated every time quarterly results come out. A company can gain or lose a point from one quarter to the next depending on its margins, its debt, or precisely its cash collection time.

About the author
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).
