VOO vs VTI Stock Comparison: AI Score, Valuation, Performance and Upside
VOO and VTI are two of the most popular Vanguard index ETFs, both with 0.03% expense ratios and similar long-term returns. VOO tracks the S&P 500 (500 large-cap US stocks); VTI tracks the total US market (3,600+ stocks including small and mid-caps). In practice, since large-caps dominate US market cap weighting, VTI and VOO perform very similarly — the correlation over any 5-year period exceeds 0.99.
VOO vs VTI is the S&P 500 large-cap-only benchmark versus the total US market with small-cap inclusion — practically identical performance given large-cap dominance of US market cap weighting, making the choice a philosophical preference for maximum simplicity (VOO) versus maximum domestic completeness (VTI).
VOO holds the edge across 3 of 5 key metrics in this comparison. VOO has delivered stronger 1-year price return (+16.61% vs +16.08% for VTI).
- prefer the most recognized US equity index (S&P 500) as the core equity holding in a long-term portfolio
- value the simplicity of investing in exactly the 500 companies that define the S&P 500 benchmark without micro-cap noise
- want large-cap only exposure with slightly lower volatility than total market exposure that includes small and micro-cap companies
- are comfortable with missing the small-cap component of the US equity market — historically a modest return increment over very long periods
- prefer owning the complete US equity market across large, mid, small, and micro-cap to eliminate any size segment exclusion
- value maximum domestic completeness — if a company is publicly traded in the US, VTI holds it proportional to market cap
- want a single ETF representing the full US equity opportunity set without selecting which size segments to include or exclude
- are comfortable with slightly more small-cap and micro-cap volatility in exchange for comprehensive US market exposure

The ETF score weights long-term returns and risk-adjusted performance most heavily, but still rewards low expense ratios, larger fund size, and broader diversification — so it can favor low-cost, broad, mega-cap funds over smaller thematic or actively-managed funds even when the latter have delivered stronger returns.

| Fund name | Vanguard S&P 500 ETF | Vanguard Morningstar Total Stock Market ETF |
| Type | ETF | ETF |

- S&P 500 is the most widely recognized US equity benchmark — VOO provides simple, transparent exposure to the 500 largest US companies
- 0.03% expense ratio is among the lowest of any ETF — minimal cost drag over long holding periods
- Large-cap only exposure provides lower volatility than small-cap-inclusive funds — large companies have more stable earnings and greater analyst coverage
- Most comprehensive US stock market exposure — 3,600+ companies vs VOO's 500, capturing the entire investable US equity universe
- Small and mid-cap exposure provides participation in smaller companies that may grow into large-cap status over time
- Same 0.03% expense ratio as VOO — equally cost-efficient while providing broader diversification
- Excludes small-cap and mid-cap US stocks — misses the small-cap premium historically observed in long-run academic studies
- Concentration in top 10 holdings (Apple, Microsoft, Nvidia, Amazon, Google, etc.) means the S&P 500 is less diversified than it appears
- S&P 500 includes only US stocks — no international diversification; global diversification requires additional international ETFs
- VTI's performance is dominated by large-cap stocks (which represent 80%+ of market cap weighting) — practical difference from VOO is relatively small historically
- Small and mid-cap exposure adds slight volatility relative to pure large-cap — small companies underperform large companies during risk-off market environments
- International diversification still requires additional ETFs — VTI covers only US stocks despite broader market-cap coverage
