The Vanguard S&P 500 ETF, SPDR S&P 500 ETF, and iShares Core S&P 500 ETF each have over $650 billion in net assets, while the Vanguard Total Stock Market ETF has surpassed $2 trillion in net assets, making it the largest. This ETF offers exposure to over 3,500 components, compared to 504 for the Vanguard S&P 500 ETF, without any added cost.

The “Ten Titans,” including Nvidia, Microsoft, and Apple, make up 39% of the S&P 500 index, with Nvidia, Microsoft, and Apple alone accounting for 20%. The S&P 500 index represents 80% of the U.S. stock market, with the Vanguard Total Stock Market ETF offering exposure to the remaining 20%.

The Vanguard Total Stock Market ETF is an excellent choice for investors looking to buy the U.S. stock market as a whole, rather than just the S&P 500 or Nasdaq-100 indexes. Despite slightly underperforming the S&P 500 ETF over the past decade, it provides a way to invest in a diversified portfolio with minimal capital required.
