1. Is VTI Enough on Its Own?

VTI invests in the entire U.S. stock market — approximately 4,000 companies — ranging from large-cap to small-cap stocks. Because it covers every segment of the U.S. market, a single position in VTI gives you broad domestic diversification. However, it does not include international stocks or bonds. If you want full global diversification, consider adding VXUS for international exposure and BND for bonds.

2. The 2-ETF Portfolio Strategy

Combining VTI (U.S. stocks) with VXUS (international stocks) covers virtually the entire global equity market. Adding BND (bonds) to the mix gives you both stock and bond diversification in three funds. This three-ETF combination is widely known as the "Vanguard Three-Fund Portfolio."

Key Investment Tips

  • 1.Start with VTI alone, then gradually add international exposure (VXUS) and bonds (BND) as your portfolio grows.
  • 2.The long-term performance difference between S&P 500 ETFs like VOO and the total market ETF VTI is minimal — choose whichever feels more comfortable.
  • 3.Beginners should aim to keep their portfolio to three or fewer ETFs to make management simple and stress-free.
  • 4.Dollar-cost averaging (investing a fixed amount each month) pairs perfectly with all-in-one ETFs for long-term wealth building.

FAQ

Should I buy VTI or VOO?
VTI covers the entire U.S. stock market — large-cap, mid-cap, and small-cap stocks — while VOO tracks only the S&P 500 large-cap index. In practice, the long-term performance difference between the two is very small. If you want exposure to small-cap stocks as well, choose VTI. If you prefer a simpler, more familiar benchmark, VOO is a great choice.
Is it okay to invest in just one ETF?
Absolutely. Owning just VTI or VOO gives you diversification across thousands of stocks in a single fund. Even Warren Buffett has recommended that most investors simply put their money into an S&P 500 index fund. Once you grow more comfortable with investing, you can gradually add bond and international ETFs to your portfolio.
