The "Magnificent Seven" Are Eating the Entire Market—Here's the Easiest Way to Own All of Them

Think the stock market is diverse? Think again. Just seven companies now control 59% of Vanguard’s flagship mega-cap growth ETF (MGK), and collectively, they’re worth $20.6 trillion.

Nvidia, Microsoft, Apple, Alphabet, Amazon, Tesla, and Meta have obliterated the S&P 500 since 2023—posting a median return of 217% versus just 72% for the broader index. Meanwhile, the other 3,491 U.S.-listed companies combined? Left in the dust.

The Numbers Tell the Story

Nvidia alone accounts for 14.28% of the MGK portfolio, followed by Apple (12.20%) and Microsoft (11.73%). All seven are betting on AI—whether it’s chips, cloud computing, autonomous vehicles, or algorithm-driven content feeds. They’ve basically become tech’s blue chips.

MGK holds just 66 stocks total, but those 66 represent 70% of the entire U.S. stock market’s value. Concentration this extreme hasn’t been seen in decades.

Should You Add This to Your Portfolio?

MGK has posted 14% annualized returns since 2007, and 18.3% over the last decade. But here’s the catch: it’s not a replacement for diversification—it’s a boost to it.

If you’d split $20,000 between Vanguard’s Total World Stock ETF and MGK ten years ago, you’d have $83,118 today instead of $58,868. That’s the power of concentrated exposure to AI and tech dominance.

The real question: Are you comfortable putting half your growth allocation into just seven companies?
