Broad Market ETFs
Broad market ETFs extend beyond the S&P 500 to represent the full U.S. equity market, including small- and mid-cap stocks that S&P 500 funds exclude. VTI is the primary fund profiled in this section.
What is a Broad Market ETF?
A broad market ETF attempts to represent the entire investable equity market within a defined geography, rather than just large-cap stocks. In the U.S. context, a total market ETF tracks an index that covers large-, mid-, small- and micro-cap stocks listed on U.S. exchanges, providing exposure to thousands of companies rather than the approximately 500 in the S&P 500.
The main practical difference between a broad market ETF and an S&P 500 ETF is the inclusion of small- and mid-cap stocks. Because U.S. total market cap is dominated by large-cap stocks, the performance of a broad market ETF and an S&P 500 ETF is often similar over many periods. However, when small-cap stocks outperform or underperform large-caps, the results diverge.
Broad market vs. S&P 500
The S&P 500 holds approximately 500 large U.S. companies. A U.S. total market ETF like VTI held 3,515 stocks as of July 31, 2026. The extra exposure relative to the S&P 500 is primarily in small- and mid-cap stocks. Because large caps dominate by market-cap weight, the total market ETF's returns are still primarily driven by those same large companies, but with a partial allocation to smaller companies.
Investors who believe the U.S. market's total return is more accurately captured by owning the whole market rather than a selected large-cap subset often prefer a total market fund. Others prefer the S&P 500's focus on the largest, most liquid companies. Neither choice has a universally correct answer; the difference is a philosophical one about which slice of the market the investor wants to own.
