Overview
ITOT and SCHB are broad U.S. stock market ETFs with nearly identical expense ratios and yield profiles. Both track complete market indexes—ITOT uses the S&P Total Market Index, while SCHB follows the Dow Jones U.S. Broad Stock Market Index—giving them near-complete overlap in holdings and performance. The main distinctions lie in fund size, inception history, and the specific composition of their underlying indexes.
How they differ
The single largest difference is asset size: ITOT holds $97.6B in AUM versus SCHB's $44.7B, giving ITOT roughly double the capital and significantly tighter bid-ask spreads in most market conditions. Both charge 0.03% in expense ratios and distribute quarterly yields around 1% (ITOT 0.98%, SCHB 1.00%), so costs and income are functionally equivalent. ITOT has a longer track record, launched in January 2004 versus SCHB's November 2009 inception. Their underlying indexes differ slightly—the S&P Total Market Index and Dow Jones U.S. Broad Stock Market Index weight holdings somewhat differently and may exclude or include micro-cap names at different thresholds—but both achieve near-complete market exposure with beta of 1.03 each.
Who each is best for
- ITOT: Fits investors building a core U.S. equity holding who value liquidity and the longest available history of index-tracking performance, or those who prefer funds with deeper institutional roots.
- SCHB: Designed for investors who already use Schwab's brokerage or fund platform, or those indifferent to the AUM difference and comfortable with a 15-year track record.
Key risks to know
- Index methodology divergence: The S&P Total Market Index and Dow Jones U.S. Broad Stock Market Index use different weighting and inclusion rules, which can lead to performance tracking differences over longer periods, particularly in periods when micro-cap or small-cap dynamics shift sharply.
- Liquidity concentration in ITOT: ITOT's substantially larger AUM may create structural liquidity advantages; conversely, SCHB's smaller size could widen its bid-ask spread during periods of heavy trading or market stress.
- Market concentration risk: Both funds track the entire U.S. stock market, which means exposure to whatever sector or mega-cap concentration dominates at any given time—currently technology and a handful of large-cap names represent a significant portion of both indexes.
Bottom line
If you prioritize liquidity and want the longest institutional track record, ITOT's $97.6B AUM and January 2004 inception offer a meaningful edge; if you hold an existing Schwab account or have no preference between functionally similar indexes, SCHB delivers identical low-cost broad-market exposure at the same price. Neither fund has a structural advantage in returns or yield—index tracking is remarkably similar across these two, so the choice hinges on liquidity comfort and brokerage ecosystem fit rather than performance.
