SCHX vs VOO: Which ETF Is Better in 2026?

The label is the same; the portfolio is not. Their top holdings overlap about 38% by weight (10 shared names: NVDA, AAPL, MSFT, AMZN, GOOGL, AVGO). That is real overlap, but each still tilts differently, so the two are genuinely different bets under one label.

Overlap reflects top holdings by weight (an approximation of full-fund overlap), as of mid-2026. Verify full holdings with each issuer.

SCHX tracks Dow Jones US Large-Cap Total Stock Market Index, and VOO tracks S&P 500. Because they follow different benchmarks, the two funds screen and weight their holdings differently, and that is what produces any gap in exposure, concentration, and return between them.

On construction, SCHX is market-cap-weighted and VOO is market-cap-weighted. They share a weighting approach, so any difference comes from the underlying index rather than the method.

So the funds cover similar ground under different rules. Read the holdings overlap above alongside the methodology here to see how much of the difference is real exposure versus labeling.

The fees match exactly at 0.03%, so cost is not the deciding factor here; the difference, if any, comes from exposure and structure.

On scale, SCHX holds about ~$72.6 billion and VOO about ~$1.7 trillion. Larger funds generally trade at tighter bid-ask spreads and carry deeper options markets, which matters if you trade actively or in size; for buy-and-hold investors it rarely changes the outcome. Both funds yield about the same (~1.00% versus ~1.0%).

VOO concentrates more weight in its largest holdings (top three about 20%), so it suits an investor who wants the theme expressed through its biggest winners and can tolerate more single-name risk. SCHX spreads weight more evenly (top three about 19%), which suits an investor who wants the same theme with less dependence on any one company. Match the fund to how much concentration you actually want.

These are descriptive profiles, not recommendations. What fits you depends on your goals, horizon, and what you already own. Walnut is not an investment adviser.

The overlap that decides most ETF purchases is not between SCHX and VOO, it is with what you already hold. ETF redundancy is invisible without looking through to the underlying holdings: you can already own most of SCHX inside a broad fund like an S&P 500 or total-market ETF and not realize it.

This is the part a generic comparison cannot answer, because it depends on your account. Connect your brokerage and Walnut looks through your funds to show your real, combined exposure, flags how much of SCHX or VOO you already own elsewhere, and tells you whether adding either just buys the same companies twice, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

Tracks a broad large-cap US index of roughly the biggest 750 companies, wider than the S&P 500 but with near-identical top holdings and return profile. At 0.03% it is Schwab's core large-cap building block, comparable to VOO or ITOT.

Tracks the S&P 500 Index, the standard measure of US large-cap equity. Effectively identical exposure to SPY and IVV at a 0.03% expense ratio. Used as a core building block in most diversified portfolios.

This is a choice of which bet you are making. If you want the theme concentrated in its biggest winners, the more top-heavy fund suits you; if you want the theme spread more evenly so no single name dominates, the more diversified one fits. Match the construction to your conviction, then check overlap with what you already own.

Schwab competes hard on cost, often matching Vanguard. Vanguard is investor-owned and known for rock-bottom fees.

SCHX and VOO share a theme but are built differently (about 38% overlap by weight), so pick the construction that matches your conviction. Either way, the decisive check is overlap with your real portfolio. Walnut can show that before you buy. It is not an investment adviser.

Both funds lean on NVDA, so understanding that one company explains a lot of what drives either ETF.
