Overview
SCHB and VOO are both broad-market equity ETFs tracking different U.S. stock indexes. SCHB uses the Dow Jones U.S. Broad Stock Market Index, which captures roughly 3,500 stocks across large, mid, and small-cap segments. VOO tracks the S&P 500, limiting exposure to the 500 largest companies. The key difference: SCHB spans the full market; VOO concentrates on large-cap names.
How they differ
The biggest distinction is breadth. SCHB's underlying index includes thousands of mid- and small-cap stocks absent from VOO's S&P 500 focus. This makes SCHB's portfolio materially broader, though both track U.S. equities. Yield is nearly identical—SCHB at 1.00% and VOO at 1.10%—with both paying quarterly and charging 0.03% in expenses. Scale differs dramatically: VOO has $1032B in assets versus SCHB's $44.7B, a 23-fold gap that gives VOO tighter bid-ask spreads and deeper liquidity. SCHB's beta of 1.03 versus VOO's 1.0 reflects slightly higher small- and mid-cap sensitivity.
Who each is best for
SCHB: Fits investors seeking exposure across all U.S. market capitalizations and wanting to own mid- and small-cap stocks as part of a single holding. Also suits those who prefer a broader market-weight structure over a large-cap concentration.
VOO: Fits investors comfortable with large-cap-only exposure and valuing the institutional-grade liquidity and cost certainty that come with the industry's largest equity ETF by assets.
Key risks to know
- Market concentration in mega-cap names. VOO's S&P 500 exposure means roughly 30–35% of the index's weight typically sits in the "Magnificent Seven" and similar mega-cap tech and growth stocks. A correction in large-cap tech hits VOO more directly; SCHB's broader index dilutes that concentration.
- Small- and mid-cap volatility in SCHB. The roughly 3,000 non-S&P 500 stocks in SCHB's index introduce higher idiosyncratic risk and wider price swings during equity sell-offs. SCHB's 1.03 beta reflects this extra sensitivity to market stress.
- Liquidity mismatch. VOO's $1032B in assets ensures near-institutional-grade trading tightness. SCHB, at $44.7B, still offers tradable liquidity but materially wider potential spreads during volatile markets.
- Index-composition differences may create sector overlap. Both track U.S. equities and will move together during broad market rallies or declines. Their holdings overlap significantly in large-cap space; the degree to which they track together depends on which sectors dominate each index at any given time.
Bottom line
Both ETFs charge identically and distribute yields near 1%, making the choice hinge on index philosophy. If you want the simplicity and liquidity of a 500-stock large-cap index, VOO's massive scale delivers institutional-grade trading efficiency. If you want exposure to the full U.S. market including thousands of mid- and small-cap names, SCHB's broader index captures that spectrum. Past performance of either index does not predict future results; the S&P 500's outperformance in recent years does not guarantee it will continue to beat broader-market alternatives.
