Total Market ETFs

Total market ETFs aim to capture the performance of the entire U.S. stock market in a single fund, including large-cap, mid-cap, and small-cap companies. These all-in-one equity funds hold thousands of stocks, providing the broadest possible diversification across the domestic market. They represent the simplest way to invest in U.S. equities and are the foundation of many index-based investment strategies.

The dominant total market ETFs include VTI (Vanguard Total Stock Market ETF), the gold standard of total market funds with over 3,600 holdings and one of the lowest expense ratios in the industry, ITOT (iShares Core S&P Total U.S. Stock Market ETF), which offers comparable coverage tracking the S&P Total Market Index, and SPTM (SPDR Portfolio S&P 1500 Composite Stock Market ETF), which covers the S&P 1500 at an ultra-low cost.

Total market ETFs are ideal for investors who want a single-fund equity solution without making decisions about size, style, or sector tilts. VTI is the most popular choice and is used by both individual investors and advisors as a core equity holding. Because these funds are market-cap weighted, large-cap stocks still dominate performance, but the inclusion of mid-cap and small-cap companies provides additional diversification and return potential. Total market ETFs are a cornerstone of three-fund portfolio strategies and work excellently in both taxable accounts and retirement plans due to their extreme tax efficiency and low costs.
