The "Magnificent Seven" are a group of seven of the largest and most influential technology-focused companies. This group includes:
All of these companies have experienced rapid growth over the last decade, and they all currently have a market cap of more than $1 trillion. As they've grown, their combined value has made up a larger -- and some would say concerning -- portion of the S&P 500.
Read on for a detailed look at the Magnificent Seven stocks as a percentage of the S&P 500, their returns over the years, and what their success means for investors.
The Magnificent Seven account for 33.8% of the S&P 500 as of Jan. 16, 2026. That's nearly three times as much as in 2015, when they made up 12.3% of the S&P 500.
The S&P 500 performed very well from the end of 2015 through 2025, with an overall return of 234.9%. However, it doesn't come close to the Magnificent Seven, which had a staggering 875.5% combined return over that same time span.
It's largely been a bull market over the last decade, which could help explain why this group of growth stocks has been so successful. From 2016 through 2025:
Because it's more diversified and not reliant on a single sector, the S&P 500 tends to weather stock market volatility better. The Magnificent Seven generally aren't as resilient during periods of economic uncertainty, as evidenced by their greater losses during down markets, most notably in 2022. However, since then, artificial intelligence (AI) has driven growth in the tech sector, helping the Magnificent Seven outpace the S&P 500.
Over the first two weeks of 2026, the S&P 500 gained 1.4%. The Magnificent Seven lost 1.3%, and only two of the seven (Alphabet and Amazon) delivered positive returns.
It has been a strong start to the year for "the other 493," a term for all the other companies in the S&P 500 index. However, the Magnificent Seven could rebound. We're still early in the year, and volatility is normal, considering this is a group of just seven stocks.
Each company's contribution to the Magnificent Seven has changed since 2015, with some growing more significantly than others.
Investors who buy S&P 500 index funds sometimes worry about how top-heavy the index is -- a logical concern given that seven companies contribute more than a third of the S&P 500's value.
These companies account for such a large share of the S&P 500 due to their exceptional performance in recent years. Anyone invested in the S&P 500 has shared in that success, so there are advantages to the Magnificent Seven's dominance.
However, the Magnificent Seven don’t come without risks, as seen in 2022. There are a few notable causes for concern, in particular:
It's possible that the Magnificent Seven will continue their success. Even if some of them fall off, other stocks in the S&P 500 will take their place.
S&P 500 index funds remain a simple and effective way to invest in stocks. If you'd like to diversify your portfolio more, you could opt for a different index fund, a combination of funds, or a self-managed portfolio of companies you select. As the success of the Magnificent Seven shows, it is possible to get market-beating returns by picking quality stocks.
