What are the Magnificent Seven stocks?

The name spread in 2023, borrowed from the 1960 western film, to describe the handful of mega-cap tech stocks that led the US market. The group is a nickname, not an official index or a fund: no exchange keeps the list, and commentators sometimes argue about who belongs in it.

The seven tickers are AAPL, MSFT, GOOGL and GOOG (Alphabet has two listed share classes), AMZN, META, NVDA and TSLA. What they share is size and their place in the main indexes, not one business. One designs phones, one sells cloud software, two live mostly on advertising, one is a retailer and cloud provider, one makes chips and one makes cars. See market cap for how company size is measured.

Magnificent Seven
A market nickname, not an index, for seven large US tech stocks: Apple, Microsoft, Alphabet, Amazon, Meta, Nvidia and Tesla. Their size gives them a large weight in the S&P 500 and the Nasdaq-100.

What does each Magnificent Seven company sell?

Knowing where the money comes from tells you which news can move each stock. In one line each, from the companies’ own reporting categories:

  • Apple: iPhone, Mac, iPad, wearables, home and accessories, plus Services (the App Store, iCloud, Apple Music, advertising, payments and more). The iPhone brought in about 53% of net sales in fiscal 2026; see how Apple makes money.
  • Microsoft: cloud computing through Azure, Microsoft 365 office software, Windows, Xbox gaming and LinkedIn. Its fiscal year ends on June 30.
  • Alphabet: mostly advertising on Google Search and YouTube, plus Google Cloud, Android, subscriptions and devices.
  • Amazon: its online store, services for the independent sellers who use it, Amazon Web Services (AWS, cloud computing), advertising and subscriptions such as Prime.
  • Meta: Facebook, Instagram, WhatsApp and Messenger, where most of the revenue comes from advertising, plus a smaller virtual and augmented reality unit.
  • Nvidia: graphics processors and complete data-center systems used to train and run AI models, plus gaming GPUs. Data center sales were about 90% of revenue in fiscal 2026; see how Nvidia makes money.
  • Tesla: electric cars, energy storage batteries for homes and power grids, and services such as charging, insurance and repairs.

Why do the Magnificent Seven move the S&P 500 and the Nasdaq-100?

Both indexes weight their members by market value. The S&P 500 uses float-adjusted market cap, meaning the value of the shares available to the public, and the Nasdaq-100 uses a modified market-cap method that trims the largest names when they grow too heavy. Either way, a company worth fifty times more than another counts roughly fifty times more. By many estimates the seven together made up around a third of the S&P 500’s value at times in 2025 and 2026; the exact share changes every day. The stock market indexes lesson compares the weighting methods.

An index move is the sum of each member’s weight × its move. In the hypothetical index below, the seven hold 30% of the weight and rise 2%, adding 30% × 2% = +0.60 percentage points. The other 493 stocks hold 70% and slip 0.5% on average, subtracting 70% × 0.5% = 0.35 points. The index closes up 0.25% although most of its stocks fell.

Index weight
The share of an index’s total value that one member represents. In a market-cap weighted index such as the S&P 500, bigger companies get bigger weights.

A bar for a hypothetical index split into the seven, 30% of the weight, and the other 493, 70%. Below it, weight × move = contribution: the seven, 30% × +2.0% = +0.60; the other 493, 70% × −0.5% = −0.35; index move +0.25%. A note reads hypothetical weights and moves: most stocks fell, yet the index rose.

How do you calculate a stock’s contribution to an index?

Contribution = weight × move. With hypothetical weights: a stock holding 7% of an index that falls 4% takes 7% × 4% = 0.28 percentage points off the index. The 100 smallest members of the same index might hold 3% between them; even if every one of them rose 5%, they would add only 0.15 points. One heavy stock outweighs a hundred light ones, and the index still falls 0.13 points on those moves alone.

That is why market commentators say a few names did the work on a given day, and why traders also check market breadth, how many stocks rose against how many fell, before reading too much into an index close.

Index contribution
How much one stock added to or took from an index move, in percentage points: its weight × its own percentage move.

Two cards with hypothetical weights. One heavy stock: weight 7%, move −4%, contribution −0.28. The 100 smallest stocks together: weight 3%, move +5%, contribution +0.15. Below, a red bar of −0.28 and a green bar of +0.15 on either side of a zero line, and a note: net effect on the index −0.13. A footer reads contribution, in percentage points = weight × move.

What is the concentration risk in the S&P 500 and QQQ?

When a few stocks carry a large weight, an index fund is less spread out than its 500 or 100 names suggest. A buyer of an S&P 500 or Nasdaq-100 fund puts a large slice of each dollar into these seven companies, and several of them depend on related themes such as AI spending, cloud demand and advertising budgets. A shock to one theme can hit several of the heaviest stocks at once.

The effect is bigger in the Nasdaq-100, which holds only 100 non-financial Nasdaq companies, so the seven make up a larger share of it than of the S&P 500. With hypothetical weights of 30% in an S&P 500-style index and 42% in a Nasdaq-100-style index, a 3% drop in the seven, with everything else flat, takes 0.90% off the first and 1.26% off the second. That is one reason QQQ often moves more than SPY on big tech news. Spreading money across sectors and styles is covered in portfolio diversification.

Two stacked columns with hypothetical weights. An S&P 500-style index, where the seven are 30% of the weight: 30% × −3% = −0.90%. A Nasdaq-100-style index, where they are 42%: 42% × −3% = −1.26%. The heading reads the seven fall 3%, all others flat; the footer reads the seven weigh more in the Nasdaq-100, so QQQ tends to move more than SPY.

How do traders use the Magnificent Seven?

Day traders of the index ETFs watch the heavy names next to the index chart. If several of the seven are rising while SPY or QQQ is flat, the rest of the market is weak; if they are falling while the index holds, buying is broad. The SPY day trading and QQQ day trading guides show how to read the ETF itself.

Earnings weeks matter most. Microsoft, Alphabet, Meta, Amazon, Apple and Tesla usually report after the close within a few weeks of each other, around late January, April, July and October; Nvidia reports about a month later because its quarters end later. On those nights the futures and the index ETFs can move with one company’s numbers. Check the dates on each company’s investor relations page:

  • Do not hold a day trade into a report: an overnight gap can jump past your stop.
  • The next morning, expect QQQ to react more than SPY when a big tech name gaps.
  • Read the single stocks with their own levels: see Tesla day trading and Nvidia day trading.
  • Remember the group is not one trade: in some years a few of the seven lead while others lag.
