The Magnificent Seven are the seven mega-cap US technology stocks — Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla — whose combined weight dominates the S&P 500's market-cap, earnings growth, and index returns, making aggregate index behaviour heavily dependent on a handful of names.
How it works
Coined by Bank of America's Michael Hartnett in 2023, the label groups seven AI- and platform-exposed giants that together account for roughly a third of S&P 500 market cap. Because the index is cap-weighted, their valuations and earnings disproportionately drive headline index moves, breadth, and the aggregate forward multiple.
Why it matters now
In 2025-2026 the Mag 7 concentrate the market's AI-capex narrative: stripping them out collapses S&P breadth and compresses the index multiple toward the historical average, so any earnings disappointment among the seven poses outsized index and macro-sentiment risk.
Example
In our briefing, the full S&P 500 traded on a forward P/E inflated by the Magnificent Seven's premium; stripping them out, the residual ~493 names compressed to a ~19x multiple — close to the long-run average — illustrating how concentrated the re-rating had become.
Frequently asked
- What is the Magnificent Seven?
- The Magnificent Seven are seven mega-cap US tech stocks — Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla — that dominate the S&P 500's market capitalisation and returns. Coined by BofA's Michael Hartnett in 2023, the group accounts for roughly a third of the cap-weighted index, making headline index moves heavily dependent on these seven names.
- Why does the Magnificent Seven matter for the S&P 500?
- The Magnificent Seven matter because the S&P 500 is cap-weighted, so the seven largest constituents drive a disproportionate share of index returns, earnings growth, and the aggregate multiple. Stripping them out sharply reduces market breadth
Glossary · equity breadth
Equity breadth is the proportion of stocks participating in a market move, measured by how many names are rising versus falling or hitting new highs. Broad breadth means gains span the index; narrow breadth means a handful of mega-caps mask underlying weakness in the median stock.

- How does the Magnificent Seven differ from the FAANG stocks?
- The Magnificent Seven update and expand the older FAANG acronym (Facebook, Apple, Amazon, Netflix, Google). The Mag 7 drop Netflix, add Microsoft, Nvidia, and Tesla, and reflect the 2023-onward AI-capex theme rather than the 2010s streaming-and-platform narrative. Nvidia in particular anchors the group as the dominant AI-infrastructure beneficiary.
- What does stripping out the Magnificent Seven do to the market multiple?
- Stripping out the Magnificent Seven collapses the S&P 500's forward multiple toward the long-run average — in one Ledger briefing, to roughly 19x. This shows the headline index valuation premium is concentrated in the seven, while the residual ~493 names trade close to historically normal levels.
