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%. Given the benchmark’s market cap distribution, which allows larger stocks to contribute more to the index’s movements, the S&P 500 has added about 19% this year.

Goldman Sachs’ equity research team led by chief US equity strategist David Kostin described the Magnificent Seven’s outperformance as a “defining feature of the equity market in 2023.” And perhaps rightfully so.
Two other charts included in Goldman’s outlook show how the Magnificent Seven have outperformed the other 493 stocks in key metrics that typically drive stock performance.
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 the index.
