The pitch for the Vanguard Growth ETF (NYSEARCA:VUG) is almost too clean. You pay 0.03% a year, roughly three cents per $100, and get the mega-cap growth trade that has driven US equity returns for the better part of a decade. Over the last ten years, VUG returned 413% against the S&P 500’s 309%. Vanguard’s historical data shows VUG beating the S&P 500 in about 95% of rolling five-year windows, a hit rate that ends most portfolio arguments before they start.
The interesting question is whether the underlying machinery still looks like a diversified fund, or has become a levered bet on four stocks.
What You’re Actually Buying
VUG tracks the CRSP US Large Cap Growth Index, which sounds broad and technically is. Then you open the holdings. NVIDIA (NASDAQ:NVDA | NVDA Price Prediction) is 13.3% of the fund. Apple (NASDAQ:AAPL) is 12.3%. Alphabet (NASDAQ:GOOG, NASDAQ:GOOGL) is 9.9%, and Microsoft (NASDAQ:MSFT) is 9.1%. Those four names alone account for 44.6% of the portfolio, and the top ten holdings account for 65%.
Making money here requires the AI capex cycle to keep compounding, NVIDIA to keep delivering quarters like 85% year-over-year revenue growth at a 63% profit margin, and Apple, Alphabet, and Microsoft to fund the picks-and-shovels boom with tens of billions in cloud and infrastructure spend. Vanguard sells you a growth index. What you own is a concentrated AI infrastructure fund with a diversification wrapper.
Does the Math Actually Work?
Over the past five years, VUG has been on equal footing with the SPY at ~83-84%. That said, the Invesco QQQ Trust (NASDAQ:QQQ) returned 102% over the same window at a 0.18% expense ratio. If your goal was pure mega-cap growth exposure, QQQ would have beaten VUG. VUG’s argument is that it captures most of that upside with a fraction of the cost drag and slightly broader coverage.
Year to date, VUG is up 7.5% while the S&P 500 is up 10.8%. Over the past 12 months, VUG returned 18.6%, compared with the index’s 21.6%. Microsoft, one of the top four holdings, is down 21% over the last year. When your fund is 9% in one stock and that stock rolls over, the low expense ratio does not save you.
The 2022 to 2023 period was worse. VUG lost 2.5% over those two calendar years, while the S&P 500 was roughly flat, at-0.5%. Both bad, but VUG was worse because concentration cut in the other direction. Rates rose, long-duration growth got repriced, and the fund suffered.
Fragility Dressed Up as Diversification
- Single-stock risk masquerading as index risk. A 13% NVIDIA weight means an NVIDIA drawdown is a VUG drawdown. The 2.2 beta on NVIDIA rides straight into your portfolio.
- Regime dependence. The 95% five-year win rate was built during falling and anchored rates, cloud buildout, and AI capex. Change the regime, and historical odds are no longer the odds.
- Correlation with what you already own. If you hold an S&P 500 fund and add VUG, you are doubling down on the top of the index.
Schwab’s SCHG offers essentially the same exposure at a similar expense ratio, and the iShares Russell 1000 Growth ETF (NYSEARCA:IWF) charges roughly 0.19% for a portfolio that is 33% in NVIDIA, Microsoft, and Apple alone. Plenty of funds offer the same concentration. The three-cent price tag is what Vanguard largely owns.
Who This Fund Actually Fits
VUG makes sense as a 10% to 20% growth sleeve for investors with a decade-plus horizon who understand they are buying the AI mega-cap trade and can sit through a 30% drawdown without selling. Pair it with a broad market fund and something outside US large-cap tech, and it does real work.
It does not fit anyone within five years of retirement who thinks they are buying a diversified growth index, or anyone using it as a core holding alongside an S&P 500 position. That is concentration you paid three cents for.
