Consisting of Microsoft, Apple, Nvidia, Amazon, Alphabet, Meta Platforms, and Tesla, the “Magnificent Seven” may be the most important stocks of this generation. After collectively rising 107% in 2023 — and another 14% so far in 2024 — each of these businesses now hold market capitalizations between $600 billion and $3.1 trillion.

To put this size in context, these stocks now account for roughly 30% of the S&P 500 index’s total market cap of $44.5 trillion. Home to many bleeding-edge technologies in today’s world, it is tough to argue that the Magnificent Seven doesn’t deserve this massive allocation of funds.

However, one company works behind the scenes to keep these juggernauts’ operations humming: Netherlands-based ASML (NASDAQ: ASML). Playing a vital role in the semiconductor supply chain, ASML helps enable the Magnificent Seven’s most ambitious technological aspirations.

Thanks to its unmatched technology, here’s how ASML secretly powers the world’s most influential companies — potentially making it a more intriguing investment than its enormous peers.

ASML’s dominant position in lithography

ASML maintains a monopoly in the extreme ultraviolet lithography (EUV) market and controls around two-thirds of the more mature deep ultraviolet lithography (DUV) niche. Lithography uses ultraviolet light to draw infinitesimal patterns onto silicon wafers. These wafers are then layered to build semiconductors, which help power smartphones, computers, data centers, cars, and AI language models.

Seeing this array of end-product use cases, it isn’t surprising that ASML’s three largest customers are the semiconductor behemoths Taiwan Semiconductor Manufacturing, Intel, and Samsung Electronics. These companies’ products (requiring ASML’s lithography) are vital to the innovation machines that comprise the Magnificent Seven.

Just how important? Let’s consider things through the lens of a snap test.

A snap test and ASML’s connection to the Magnificent Seven

Popularized by Motley Fool’s co-founder David Gardner, a “snap” test asks us to imagine a world where we snap our fingers and a company’s products disappear. In ASML’s case, many of today’s advanced electronics would be much different or less sophisticated — at a minimum. At worst, they may be nonexistent.

How is this so?

First, ASML’s largest customer, Taiwan Semiconductor (TSMC), counts Apple as its biggest client. Via this trickle-down effect from ASML to TSMC to Apple, there is no doubt that Apple’s consumer electronics would be entirely different without using ASML’s lithography. Sans ASML’s help, Apple’s products might be physically larger, slower, less powerful, and have fewer features.

Meanwhile, another of TSMC’s largest customers is Nvidia, which relies upon the company to create chips for its graphic processing units (GPUs). These GPUs from Nvidia are then distributed to the rest of the Magnificent Seven, for use in:

• Microsoft’s Azure cloud platform and its artificial intelligence (AI) ambitions

• Amazon and its Amazon Web Services (AWS) — as well as its AI endeavors

• Alphabet’s Google cloud platform and its numerous AI concepts

• Meta’s data centers and its AI product, LLaMa

• Tesla’s full self-driving mode, which uses Nvidia chips to train its AI models for autonomous driving

While it is virtually impossible to imagine the extent to which a world without ASML would change, it is clear that the Magnificent Seven would look dramatically different.

ASML is good for shareholders, too

Posting a total return above 950% over the last decade, ASML is not only crucial to the world of advanced technology, but also shareholder-friendly.

Thanks to its dominant positioning in the lithography industry, ASML maintains an incredible net profit margin of 28%. The company has repurchased 1% of its shares annually since 2014, bolstered by this immense profitability while boosting its dividend payments ninefold.

While ASML may not match its 14% annualized revenue growth rate from the last decade over the next 10 years, it grew sales by 30% in 2023 and has clear megatrends working in its favor. Supported by growth drivers in end markets such as the ongoing energy transition, the “electrification of everything,” and AI, the semiconductor market should double within 10 years, according to ASML’s CEO Peter Wennink.

Commanding a lofty price-to-earnings (P/E) ratio of 43 today, the market expects this steady growth to come to fruition, with ASML maintaining its leadership position for many years. Since ASML secretly powers the Magnificent Seven in many ways, yet trades at nearly twice the valuation of the S&P 500’s average, dollar-cost-averaging buys would be prudent for investors.
