One chart shows how the ‘Magnificent 7’ have dominated the stock market in 2023

The S&P 500 (^GSPC) has never been this top-heavy.

The “Magnificent Seven” tech stocks — Apple (AAPL), Alphabet (GOOGL, GOOG), Microsoft (MSFT), Amazon (AMZN), Meta (META), Tesla (TSLA), and Nvidia (NVDA) — make up 29% of the S&P 500’s market cap.

And a chart in Goldman Sachs’ 2024 US Equity Outlook shows that’s the largest portion of S&P 500 market cap ever dominated by just seven stocks.

That perspective helps explain a second chart from Goldman that shows the Magnificent Seven have gained 71% while the other 493 stocks have added just 6%.

From 2013 to 2019, the Magnificent Seven stocks grew at a compound annual growth rate of 15% compared to a 2% growth rate from the rest of the pack. That margin narrowed in the past two years to 18% and 15% respectively, but Goldman sees it widening again in the coming years. From 2023 to 2025, Goldman sees the Magnificent Seven growing at a compound annual growth rate of 11% compared to a 3% rate for the rest of the S&P 500.

The Magnificent Seven’s net profit margin also outperforms, where its 19% margins are above the 9.8% for the rest of the companies. Not to mention, the long-term earnings per share growth expectations are 17% for the Seven while that number sits at 9% for the other companies in…
