Let’s break it down.
Vanguard S&P 500 ETF (VOO)
The Vanguard S&P 500 ETF (VOO) is a popular option for investors who want exposure to large U.S. companies. It follows the S&P 500 Index (SPX), which is often seen as a key measure of the U.S. stock market and overall economic health.
VOO is heavily tilted toward tech stocks and holds about 507 companies, with total assets of $825.92 billion. Compared to VTI, it is more top-heavy, meaning a larger share of its performance comes from a few big companies. In fact, its top 10 holdings make up about 36.3% of the portfolio, higher than VTI’s roughly 32%.
VOO’s top 5 holdings are Nvidia (NVDA), Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), and Alphabet (GOOGL).
Vanguard Total Stock Market ETF (VTI)
The Vanguard Total Stock Market ETF (VTI) gives investors exposure to almost the entire U.S. stock market. Currently, VTI holds 3,466 stocks and manages about $565.25 billion in total assets.
Like VOO, VTI is still somewhat top-heavy because big companies dominate the market today. However, it is slightly more diversified.
VTI’s top holdings—Nvidia, Apple, Microsoft, Amazon, and Alphabet—are the same as VOO’s. The main difference is that VTI owns many more stocks, giving investors broader exposure beyond just the largest companies.
Conclusion
VOO tracks only large U.S. companies in the S&P 500, making it more focused and stable, while VTI covers the entire U.S. stock market, including small- and mid-cap stocks for broader diversification. In short, VOO is more concentrated, whereas VTI gives you exposure to the full market in one fund.
For most long-term investors, VTI may be slightly better positioned heading into 2026 due to its broader market exposure and added diversification.
