What is the Magnificent Seven (M7)? 7 giant companies that drive the US stock market

[Summary]

What is Magnificent Seven (M7)?

7 giant technology companies representing the US stock market

It is a word that refers to

The seven common constituent companies are:

• Apple
• Microsoft
• NVIDIA
• Amazon
• Alphabet
• Meta Platforms
• Tesla

All of them are companies with global services and platforms, and have a large impact on the S&P 500 and NASDAQ 100.

However, M7 does not mean that you can feel safe if you buy all seven companies.

As of 2026, there will be a difference between companies where it is easy to see profit growth through AI investment and companies whose expectations are likely to be ahead of the curve.

Understanding M7 is also quite important in understanding US stock indexes.

What is the Magnificent Seven?

"Magnificent" means "great" or "excellent."

The word is originally known as the English title of the movie ``Seven People in the Wilderness,'' but it is also used in the stock market to refer to the seven giant tech companies that drive the U.S. market.

From 2023 onwards, the term M7 has rapidly spread when talking about the rise in U.S. stocks.

The reason is simple.

The market capitalization of these seven companies is so large that any movement in their stock prices will have a strong influence on the movements of the S&P 500 and NASDAQ 100.

M7 constituent companies

M7 is commonly referred to by the following seven companies.

These seven companies are not just large companies.

We are at the center of the modern digital economy, including smartphones, the cloud, search, SNS, EC, AI semiconductors, and EVs.

Why is M7 attracting attention?

The reason why M7 is attracting attention is not just because the stock price has risen.

This is because the actual business scale, profit margin, cash generation ability, amount of data, and customer base are extremely large.

1. High profit growth

The AI boom has increased demand for data centers, cloud, semiconductors, and advertising platforms.

NVIDIA, in particular, has become a symbol for its GPUs for AI.

Microsoft, Amazon, and Alphabet captured AI demand in the cloud, and Meta attracted attention for improving the efficiency of advertising and AI investment.

2. Significant impact on S&P500

The S&P 500 is an index of 500 large-capitalization companies in the United States, weighted by market capitalization.

In other words, the larger the market capitalization of a company, the greater its influence on the index.

The image structure is as follows.

S&P500
├ M7
└ About 493 other companies

If M7 rises significantly, the overall index tends to rise even if other stocks are not as strong.

Conversely, if M7 collapses, the index tends to become heavier.

3. Being at the center of the AI market

The following trends have occurred in the AI market in recent years.

Expanding the use of generative AI
↓
Increase in data center investment
↓
Expanding demand for AI semiconductors and cloud computing
↓
Expected profit growth for M7

Companies that make AI itself, companies that have the cloud that runs AI, and companies that make the semiconductors necessary for AI processing.

M7 is involved in all of this.

7 companies are not the same

This is quite important.

Although they are grouped together with M7, the contents of the seven companies are quite different.

In particular, Tesla is a stock that has large price fluctuations even among M7, and its evaluation is easily divided.

While Apple is also a huge company, the market is waiting to see how far the direct benefits of the AI boom will turn out to be.

In other words, M7 is not "seven companies with the same theme".

Although they are a group of giant companies that drive the U.S. market, they each have different business risks and growth drivers.

Advantages of M7

World's highest level of competitiveness

M7 companies have products and services that are used all over the world.

Apple's iPhone, Microsoft's Office and Azure, Google Search, Amazon's EC and AWS, Meta's SNS, NVIDIA's GPU, Tesla's EV.

All of these businesses are difficult to replace easily.

Strong cash generation ability

Big tech companies' strength lies in more than just their sales volume.

Many companies have high profit margins and can easily generate free cash flow.

The funds can be used for AI investment, research and development, share buybacks, and M&A, making it easier to further increase competitiveness.

Index investing is also naturally easy to own.

If you invest in the S&P 500 or NASDAQ 100, you will indirectly own M7.

Being able to capture the growth of M7 through an index fund without having to buy individual stocks is an easy-to-understand advantage for beginners.

M7 risks

1. Concentration risk

If the M7 ratio becomes too high, the price movements of the US stock index will be more influenced by a few large companies.

Even if you think you're buying the S&P 500, it's actually heavily influenced by M7.

It's easy to get into this situation.

2. Regulatory risk

Large platform companies are more likely to be subject to regulation by national governments.

There are many points at issue, including antitrust, data usage, advertising, app stores, AI regulations, and personal information protection.

The larger the business, the greater the social responsibility.

3. High rating risk

Even if the company is good, returns will be dampened if the stock price is too high.

If the market is already pricing in high growth, the stock price may fall even if the financial results are not bad.

M7 is a group of stocks where you can look at whether a stock can continue to exceed expectations, rather than whether it will go up because it is a good company.

Relationship with New NISA

Popular new NISA investment trusts include the S&P500-linked type and the NASDAQ100-linked type.

If you buy these products, your investment ratio in M7 will naturally increase.

S&P500・NASDAQ100

Holds a lot of M7 indirectly

In particular, the NASDAQ100 has a high tech ratio, so it is easily affected by M7.

On the other hand, M7 is also included in global stocks such as Orcan.

However, because it is diversified across the world, it tends to be slightly less concentrated in US large tech than the S&P 500 and NASDAQ 100.

What investors need to know

The word FOMO is often used in the M7 market.

FOMO stands for "Fear of Missing Out" and means the fear of missing out.

Furthermore, the word FEMO is sometimes used in the AI market.

This is used in the context of "Fundamental Earnings Momentum," or the fear of missing out on earnings growth momentum.

People buy it not just because it's popular, but because it's actually increasing profits.

This is the strength of the M7 market.

However, no matter how good a company is, it will not continue to rise forever.

When investing, you need to consider the following three things separately.

• Is the business strong?
• Are profits growing?
• To what extent do stock prices incorporate this?

If these three things shift, even good companies will experience stock price adjustments.
