Vanguard’s VOO and VTI ETFs provide broad market access but differ in sector concentration and market-cap exposure.
The Vanguard S&P 500 ETF (VOO) tracks 505 large-cap U.S. stocks, with a heavy 39.2% weighting in its top 10 holdings—all tech companies. Information technology dominates the fund at 38.6%, followed by financials at 11.3%. VOO’s structure aligns with bets on mega-cap tech growth and the AI sector’s expansion.
The Vanguard Total Stock Market ETF (VTI) holds 3,484 stocks across all market caps and sectors, including all VOO constituents. Its broader diversification reduces concentration risk but may dilute exposure to high-growth segments like tech. Both ETFs serve as low-cost, one-stop investment options for long-term portfolios.
