Overview
SCHB and VOO are both broad-market equity index ETFs tracking large-cap U.S. stocks, but they differ in scope. SCHB tracks the Dow Jones U.S. Broad Stock Market Index, which includes large-, mid-, and small-cap stocks across the full market. VOO tracks the S&P 500 Index, which is limited to 500 large-cap companies. The key distinction is breadth: SCHB captures the entire U.S. equity market, while VOO focuses on the blue-chip segment.
How they differ
The single biggest difference is index composition. SCHB holds thousands of stocks spanning all market capitalizations through its broad-market index, while VOO holds only 500 large-cap names. This means SCHB has meaningful exposure to mid- and small-cap equities that VOO excludes entirely—a structural difference that drives their risk and return profiles.
Second, their yields and distributions differ slightly. SCHB distributes at 1.09%, while VOO yields 1.03%. Both pay quarterly, so the difference is modest but real over time.
Third, SCHB and VOO are identical on cost—both charge 0.03%—but differ dramatically in asset base. VOO manages $1041B versus SCHB's $44.9B, making VOO one of the largest ETFs globally. Beta also separates them: SCHB reports 1.03, suggesting slightly more volatility than the broad market, while VOO's 1.0 aligns with large-cap indices by definition.
Who each is best for
- SCHB: Fits investors seeking maximum diversification across U.S. equity market-cap tiers in a single holding, including exposure to mid- and small-cap stocks that large-cap-only strategies exclude.
- VOO: Fits investors who want pure large-cap index exposure and prefer a fund with the deepest liquidity and smallest fee in the large-cap space.
Key risks to know
- Index mismatch: SCHB's broad-market exposure includes mid- and small-cap stocks, which historically exhibit higher volatility and drawdowns than large-cap-only indices. The composition difference means SCHB and VOO will diverge meaningfully in market stress.
- Small-cap sensitivity: SCHB's embedded small-cap allocation amplifies cyclical and recession risk relative to VOO. During equity-market downturns, smaller-cap holdings may underperform large-cap anchors.
- Rebalancing drag: SCHB's broader holdings increase the number of positions to manage and rebalance, which could introduce small performance differences over very long periods as the fund executes larger numbers of trades.
Bottom line
If you want the entire U.S. stock market in one fund, SCHB delivers broad diversification across all tiers; if you prefer to focus on large-cap stability and the simplicity of the S&P 500, VOO offers the same rock-bottom fee with a vastly larger asset base. The choice hinges on whether you view small- and mid-cap omission as a meaningful gap or a reasonable boundary for a core holding. Past performance does not predict future results.
