The short version

  • Seven mega-caps make up roughly half the Nasdaq-100 by weight.
  • Each has a personality: Nvidia leads, Microsoft and Apple steady, Tesla runs its own race.
  • When five or six agree, the index trends. When they split, expect chop.

Do this before the next open

Pull up all seven names on one screen. Mark each one green, red, or flat versus yesterday's close, then write down whether today is agreement or disagreement — and what that implies for how aggressive you should be.

The Magnificent Seven are the mega-caps that dominate the Nasdaq-100 by weight: Microsoft, Apple, Nvidia, Alphabet, Amazon, Meta, and Tesla. Together they make up roughly half the index. That concentration is the single most useful fact in NASDAQ trading.

Weight is leverage

If a name is eight percent of the index and it moves three percent, it drags the index almost a quarter percent by itself — before a single other stock trades. That is why the index can be red while most of its members are green, and why 'breadth' matters. When you know the weights, index moves stop looking random.

Each one has a personality

  • Nvidia is the volatility engine. It moves first, moves furthest, and drags sentiment with it.
  • Microsoft and Apple are the ballast. When they trend quietly, the index trends quietly.
  • Alphabet and Meta trade on their own news cycles and can diverge from the group for weeks.
  • Amazon straddles tech and retail, so it reacts to consumer data other names ignore.
  • Tesla is the outlier — highest beta, most headline-driven, thinnest correlation to the rest.

Confirmation and divergence

When five or six of the seven push the same direction at the open, index moves tend to continue. When two lead and four fade, the index move is being carried by one or two names and is far more likely to reverse. That single read — do they agree — filters out a large share of bad trades.

Education only. Nothing in this lesson is a signal or a recommendation to trade. Trading involves substantial risk of loss.
