The Schwab U.S. Broad Market ETF (SCHB 1.23%) and iShares Core S&P Total U.S. Stock Market ETF (ITOT 1.24%) are both low-cost, ultra-diversified U.S. equity ETFs with virtually identical performance, yield, and sector allocations, but ITOT is larger and trades more heavily.
Both SCHB and ITOT aim to give investors broad exposure to the entire U.S. stock market, including large-, mid-, and small-cap companies. This comparison looks at their cost, performance, portfolio breakdown, and trading details to help investors decide which ETF may align better with their needs.

What's inside
ITOT seeks to mirror the entire U.S. equity market, holding 2,498 stocks as of late 2025. Its sector allocation is led by technology at 33%, financial services at 13%, and consumer cyclical at 10%. Top positions include Nvidia Corp (NVDA 1.45%) at 6.91%, Apple Inc (AAPL 2.01%) at 6.03%, and Microsoft Corp (MSFT 0.36%) at 5.41%. The fund has a long track record, with 21.9 years since inception, and no unusual strategies or quirks.
SCHB tracks a similarly broad universe, with 2,408 holdings and nearly identical sector tilts — technology at 34%, financial services at 13%, and consumer cyclical at 10%. Its top three positions are also Nvidia, Apple, and Microsoft, in slightly different weights. Neither fund layers on leverage, ESG screens, or currency hedging, so their exposures are straightforward and closely aligned.

What this means for investors
The differences between the Schwab U.S. Broad Market ETF (SCHB) and iShares Core S&P Total U.S. Stock Market ETF (ITOT) are minimal, which can make choosing between them a challenge. Both are ultra-low-cost, highly diversified ETFs tracking the total U.S. stock market. In terms of performance, SCHB and ITOT offer the same dividend yield although SCHB delivered a tad bit better growth over the past five years.
The biggest difference is ITOT's larger assets under management of $80.4 billion compared to SCHB's $38.3 billion. This gives ITOT slightly more liquidity than SCHB. However, since both possess large AUMs, they are already very liquid.
ITOT's holdings are a bit more comprehensive, since its fund contains more holdings, but again, the difference is minimal. This makes both good broad-market ETFs, and excellent choices for a long-term, passive investment strategy.
The bottom line is that these funds are nearly identical. A key difference between ITOT and SCHB comes down to investor preference over who manages the fund, Schwab or iShares.
