Overview
ITOT and SCHB are both broad-market U.S. equity ETFs designed to track the entire stock market with minimal fees. The key difference is their underlying index: ITOT follows the S&P Total Market Index, while SCHB tracks the Dow Jones U.S. Broad Stock Market Index. Both charge 0.03% annually and distribute dividends quarterly, but they differ modestly in size, inception date, and the subtle composition differences between their respective benchmarks.
How they differ
The two funds track different market-cap-weighted indexes, which creates minor but measurable differences in holdings. ITOT's S&P index and SCHB's Dow Jones index overlap substantially but weight individual stocks differently and may include or exclude micro-cap names at slightly different thresholds. ITOT is older (launched in 2004) and significantly larger at $91.4B in AUM versus SCHB's $42.3B, which typically means tighter bid-ask spreads and lower trading friction for ITOT. Both charge identical 0.03% expense ratios and report 1.04% betas, but ITOT's distribution rate is 1.02% compared to SCHB's 1.04%—a negligible spread reflecting the slight index differences rather than any structural divergence in strategy or fees.
Who each is best for
ITOT: Fits investors seeking maximum liquidity and the longest track record in a total-market vehicle. The larger asset base and earlier inception date appeal to those who prioritize established, stable index exposure with the tightest possible trading costs.
SCHB: Designed for investors with accounts at Schwab or those who value alignment with the Dow Jones methodology. The slightly higher distribution rate and solid $42.3B AUM make it a credible alternative for buy-and-hold investors indifferent to fund size or inception date.
Key risks to know
- Index methodology drift: The S&P Total Market Index and Dow Jones U.S. Broad Stock Market Index apply different stock selection and weighting rules. Over time, these can cause performance to diverge, particularly in small- and micro-cap segments, though the correlation typically remains very high.
- Concentration in mega-cap tech: Both funds hold the entire U.S. market, so both carry exposure to the outsized weight of mega-cap technology stocks. A significant market rotation away from large-cap growth could impact both similarly, though the degree of that exposure may vary slightly by index construction.
- Liquidity in market stress: While both are highly liquid, ITOT's substantially larger AUM provides a structural advantage during volatile markets; SCHB may face wider spreads in extreme stress conditions, though this risk is modest for an ETF of its size.
Bottom line
If you prioritize the longest track record and largest asset base, ITOT stands out; if you're a Schwab client or indifferent to a $49B AUM difference, SCHB delivers equivalent broad-market exposure at the same cost. The index methodology differences are real but historically immaterial to performance. Past performance does not predict future results.
