Vanguard Growth ETF (VUG) Carries Massive AI Concentration Risk Inside Its $220 Billion Portfolio

The Vanguard Growth ETF (VUG) holds 147 stocks, a number that implies broad diversification across the market’s growth segment.

However, as of June 30, the fund’s 10 largest holdings accounted for approximately 60% of its total assets.

That means for every dollar invested in VUG, about 60 cents are riding on fewer than a dozen names, most of them deeply tied to the AI trade.

Nvidia (NVDA) is the fund’s largest single holding at 12.6% of assets, while Apple (AAPL) comes in second at 11.7% of assets.

Together, those two positions alone represent roughly 24% of the entire portfolio, an extraordinary concentration in just two stocks within a 147-stock fund.

Microsoft (MSFT) holds a 7.6% weighting, with Alphabet’s (GOOGL, GOOG) two share classes combining for 10.3%, Amazon (AMZN) at 4.5%, and Broadcom (AVGO) at 4.3%.

Meta Platforms (META) sits at 3.4%, Tesla (TSLA) at 3.3%, and Eli Lilly (LLY) rounds out the top ten at 2.8%, bringing the top ten total to roughly 60%.

This concentration did not result from active stock-picking at Vanguard, as the fund tracks the CRSP US Large Cap Growth Index, which weights companies by free-float-adjusted market value.

When a handful of stocks lead the market higher for years, an index like this concentrates automatically, with winners simply growing into ever-larger weights over time.

The risk runs in both directions, and the arithmetic on the downside is straightforward and worth understanding for any investor holding this fund.

Nvidia alone, at 12.6% of assets, can move the entire fund by more than a percentage point in a single bad trading session.

If the fund’s five biggest positions, Nvidia, Apple, Microsoft, and Alphabet’s two share classes, fell 20% while every other holding held steady, the fund would drop approximately 8%.

If the entire top 10 declined 30% simultaneously, the fund would lose roughly 18% before accounting for smaller AI-adjacent names further down the holdings list.

There is recent historical precedent for severe drawdowns of this kind, with the fund losing 33.1% in 2022, the last calendar year in which richly valued growth stocks fell sharply.

The same concentration that creates downside risk has also powered exceptional returns, with the fund returning 46.8% in 2023, 32.7% in 2024, and 19.4% in 2025.

Since its 2004 inception, VUG has compounded at approximately 12% annually, and an expense ratio of just 0.03% makes it an exceptionally cost-efficient vehicle for capturing large-cap growth.

Investors who already hold S&P 500 index funds or own these tech giants directly should recognize that adding VUG significantly doubles down on positions they already carry in their portfolios.

At today’s weightings, VUG functions less like a broadly diversified growth fund and more like a concentrated bet on America’s largest technology companies, with a long tail of smaller holdings along for the ride.
