Apple is one of the highest-rated companies across my entire tracked universe, powered by a closed ecosystem that locks in customers and a record quarter. But the stock trades today at the priciest point of its last five years, more than four times above my fair buy price, right as the company changes CEO for the first time in fifteen years. Near-perfect quality, a price that isn't: here's how I separate the two.

A record quarter, just as Apple changes captains

In 2026, Apple is going through one of the most symbolic turning points of its recent history. Tim Cook, at the helm since Steve Jobs's death in 2011, fifteen years of leadership, has announced he will step down as CEO on September 1, 2026, succeeded by John Ternus, until now senior vice president of hardware engineering. Cook will remain executive chairman of the board, but this is Apple's first CEO transition since the Jobs era.

This transition arrives while the numbers themselves are excellent: in the quarter ended March 2026, iPhone sales jumped 22% to $57.99 billion, a spring-quarter record, driven by extraordinary demand for the iPhone 17 lineup. Services (App Store, iCloud, Apple Music, AppleCare, advertising) also hit a record, at $31 billion, up 16% year over year. This is exactly the kind of moment where you need to resist confusing good news (the results) with a completely different question: the price paid today for that quality.

23 out of 25 criteria: why Apple scores one of the best marks I measure

For very large caps like Apple, my filter uses an extended 25-criteria version (versus 10 for most companies), adding structural questions: is the company dependent on commodities? On interest rates? On government contracts? Is its end market growing? Is it asset light (few factories, little capital tied up)? Does it have an identifiable moat? Apple passes every one of these structural questions: it isn't dependent on commodities, rates, or government, it operates in a growing end market, it remains asset light despite its size, and its moat combines high switching costs (leaving the iPhone for another ecosystem means losing your habits, your photos, your purchases, your iMessage circle) and economies of scale.

On the strictly financial side, net margin reaches 27.2%, free cash flow margin 25.6%, and cash return on capital employed tops out at 65.4%, a level with almost no equivalent for a company of this size. The cash conversion cycle is negative (minus 54 days): Apple collects from customers before paying its suppliers, a 'float' model comparable to Amazon's or Costco's, letting it fund part of its operations with its own suppliers' money rather than its own capital.

The two failing criteria: growth that slowed for five years

The only two failing criteria in my filter concern five-year growth: sales grow just 3.0% a year on average, and free cash flow per share only 3.1% a year, well below my 10% threshold. Seen as a single snapshot, this weakness might be surprising for the most valuable company in the world. Seen in motion, the story is more interesting: revenue went from $274.5 billion in 2020 to $394.3 billion in 2022 (the post-Covid iPhone super-cycle), before slipping slightly to $383.3 billion in 2023, then gradually climbing back to $391.0 billion in 2024 and $416.2 billion over the last twelve months, a new record, driven by the 2026 rebound.

Free cash flow follows a similar but bumpier path: $73.4 billion in 2020, a peak of $111.4 billion in 2022, then a pullback to $99.6 billion in 2023, a recovery to $108.8 billion in 2024, and $98.8 billion over the last twelve months, a level still below the 2022 peak despite higher revenue today. In other words, Apple sells more than in 2022 but converts those sales into available cash slightly less efficiently, a signal worth watching (component cost pressure, particularly memory, and AI-related investment) rather than an immediate worry, given that cash ROCE remains exceptional.

The real bet: AI, and a dependency choice that stands out

Several industry observers describe 2026 as the year Apple 'finally enters the AI race,' after long appearing to lag its rivals. At its June 2026 developer conference, Apple unveiled a new version of Siri, its voice assistant, relying on a partnership with Google for the AI models powering it. That's a striking choice for a company used to controlling everything in-house (chips, operating system, ecosystem): rather than developing a competitive AI model alone, Apple chose to lean on a rival's technology to catch up faster.

It's a double-edged bet. On one hand, it lets Apple offer a credible AI experience without the years of in-house research that would otherwise require. On the other, it exposes the company to a kind of technological dependence it has never accepted on its core business (the processor, the operating system). Some observers call 2026 a genuine stress test for Apple's strategy: its rivals are moving faster on AI, its component costs are spiking for reasons outside its control, and its leadership is changing at the same time. This isn't an immediate red flag (the quarter remains excellent), but it's the kind of backdrop worth watching closely over the coming quarters.

The price: at the priciest point of its recent history

Apple's P/FCF (price-to-free-cash-flow, the stock price divided by the cash it generates each year) stands at 42.6 times. Over its last five years, this multiple has almost always sat lower: today's level ranks in the 98th percentile of its own history, meaning it's pricier than 98% of trading days over the past five years. Apple has almost never been this expensive relative to its own generated cash.

My model calculates a fair buy price of $81.28 for Apple, based on current free cash flow per share and a conservative exit multiple consistent with its quality. The current price, $333.74, sits 75.6% above that target, more than four times the level I'd consider reasonable under this model. Compared to its sector (consumer electronics), Apple ranks in the 88th percentile for expensiveness, well above the sector median (12.9 times), though this comparison has its limits: most consumer electronics makers sell pure hardware, without the high-margin Services engine Apple has built around its ecosystem, which justifies part of the gap, though probably not all of it.

It's the mirror image of the Adobe case (an elite company priced cheaper than usual, because the market fears a risk that never materialized): here, an elite company is priced far more expensively than usual, even as its five-year growth stays modest. Both cases teach the same lesson, in opposite directions: quality and price are two separate questions, and an excellent business remains a poor investment if the price paid leaves no margin of safety.

How I make the call, without emotion

Apple's quality isn't in question: 23 out of 25 criteria, one of the strongest moats I measure, a record quarter, a Services margin engine gathering steam. But the question is never 'is this a good business?', it's always 'is this the right price today?'. At 42.6 times free cash flow, in the 98th percentile of its own expensiveness history, and more than four times above my fair buy price, Apple leaves absolutely no margin of safety.

If you believe the AI bet (even leaning on Google's technology), the Services momentum, and the Tim Cook to John Ternus transition will all unfold smoothly, you can justify paying a premium for a company of this quality. But at this price level, the slightest disappointment, a quarter that misses, a hiccup in the leadership transition, further AI delays, leaves very little cushion. I never rush into exceptional quality without checking the price: I set a target, and I wait for it to come to me, never the other way around.

FAQ

Why does Apple score 23 out of 25 in the quality filter?

Because it passes nearly every financial and structural criterion I measure: profitability, free cash flow margin, 65.4% return on capital, a switching-cost and scale moat, a growing end market, no dependence on commodities or rates. The only two failing criteria concern five-year growth, slower than my 10%/year threshold.

Is Apple's CEO change a risk for the stock?

Tim Cook is stepping down as CEO on September 1, 2026, after fifteen years, succeeded by John Ternus, until now head of hardware engineering. It's Apple's first transition of this kind since the Steve Jobs era, and a factor worth watching, though Ternus is an internal promotion, which generally limits the risk of strategic disruption.

Why does Apple rely on Google for its AI instead of its own technology?

In June 2026, Apple unveiled a new version of Siri using models developed with Google, a partnership letting it catch up on AI faster than developing a competitive model alone. It's an unusual choice for a company used to controlling everything in-house, exposing Apple to a form of technological dependence on a strategic issue.

Should you buy Apple at its current price?

According to my model, no: the price ($333.74) sits 75.6% above my fair buy price ($81.28), and the 42.6x P/FCF ranks in the 98th percentile of the stock's own history, its priciest level in 5 years. The quality is exceptional, but the price leaves no margin of safety. This is not investment advice, do your own research.

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).
