The choice between the State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF (NYSEMKT:SPTM) and Schwab U.S. Broad Market ETF (NYSEMKT:SCHB) depends on whether an investor seeks exposure to 1,512 established firms or a broader basket of 2,410 companies.
Both funds serve as core building blocks for U.S. equity exposure. While SPTM tracks the S&P Composite 1500, SCHB follows the Dow Jones U.S. Broad Stock Market Index. They aim to capture the vast majority of the investable domestic market at the lowest possible cost for long-term investors.
| Metric | SPTM | SCHB | |---|---|---| | Issuer | State Street | Schwab | | Expense ratio | 0.03% | 0.03% | | 1-yr return (as of June 8, 2026) | 24.9% | 24.9% | | Dividend yield | 1.04% | 1.01% | | Beta | 1.00 | 1.01 | | AUM | $13.3 billion | $42.4 billion |
Beta measures price volatility relative to the S&P 500; beta is calculated from five-year monthly returns. The 1-yr return represents total return over the trailing 12 months. Dividend yield is the trailing-12-month distribution yield.
These ETFs are among the most affordable in the category, each charging an expense ratio of 0.03%. Both funds delivered identical one-year returns of 24.9% through June 8.
| Metric | SPTM | SCHB | |---|---|---| | Max drawdown (5 yr) | (24.1%) | (25.4%) | | Growth of $1,000 over 5 years (total return) | $1,842 | $1,787 |
The Schwab U.S. Broad Market ETF provides exposure to 2,410 stocks, reaching deeper into the small-cap segment than its counterpart. Its sector allocation is led by technology at 37%, financial services at 11%, and communication services at 10%. Its largest positions include Nvidia (NASDAQ:NVDA) at 6.99%, Apple (NASDAQ:AAPL) at 6.33%, and Microsoft (NASDAQ:MSFT) at 4.34%. This fund, launched in 2009, has a trailing-12-month dividend of $0.30 per share.
In contrast, the State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF uses a more selective index of 1,512 companies, which results in slightly higher concentration in its largest positions. Its top holdings include Nvidia at 7.37%, Apple at 6.43%, and Microsoft at 4.44%. The portfolio tilts toward technology at 37%, financial services at 11%, and consumer cyclical at 10%. This fund was launched in 2000 and has paid $0.95 per share over the trailing 12 months.

The Schwab U.S. Broad Market ETF (SCHB) and State Street SPDR Portfolio S&P 1500 Composite Stock Market ETF (SPTM) are both compelling funds for investors who want exposure to the overall U.S. stock market. Choosing which to invest in is not straightforward given how they are so similar to each other.
Both offer nearly identical one-year performance, betas, and expense ratios, although the State Street fund offers a slightly higher distribution payout with a dividend yield of 1.04%, compared to 1.01% for the Schwab ETF. But the factors that set the pair apart can be the key components that sway a buy towards one versus the other.
State Street’s SPTM had a lower max drawdown over the past five years, contributing to larger growth over SCHB. It tracks the S&P Composite 1500, so for investors interested in these stocks, SPTM is the clear choice. Its fewer number of holdings represents about 90% of the investable U.S. equity market.
SCHB has a much larger AUM, giving it superior liquidity. This can be a reason to choose Schwab’s fund, since it results in tighter bid-ask spreads. Because it tracks the Dow Jones U.S. Broad Stock Market Index, SCHB includes far more holdings, which provides greater exposure to smaller companies than SPTM.

Four leading AI models discuss this article
"Neither ETF offers a material edge over the other or over cheaper total-market alternatives for most investors."
The article correctly flags that SCHB and SPTM are near-clones at 0.03% expense ratios with identical 24.9% one-year returns, yet it underplays how SCHB's 2,410 holdings versus SPTM's 1,512 deliver incremental small-cap beta that only matters in specific regimes. SPTM's modestly better five-year growth ($1,842 vs $1,787) and lower drawdown (-24.1% vs -25.4%) came from tighter large-cap concentration, not superior indexing. The Motley Fool pivot at the end to pushing 10 individual stocks reveals the piece is less comparison than lead-gen.
If small-cap outperformance resumes, SCHB's extra 900 holdings could widen the return gap in its favor, rendering SPTM's historical edge irrelevant for forward-looking portfolios.
"The best choice is regime-dependent: SPTM’s concentration can cushion downturns but may lag in rallies, while SCHB offers breadth and liquidity with no guaranteed outperformance."
Both funds deliver near-identical core U.S. exposure at 0.03% expense. The article’s edge is the depth of SCHB (2,410 stocks) versus SPTM’s 1,512, which translates into different risk/return dynamics. SPTM shows a marginally better 5-year max drawdown and five-year growth ($1,842 vs $1,787), implying heavier concentration in mega‑caps can be somewhat protective in downturns but underperforms if small/mid caps rally. SCHB’s much larger AUM hints at tighter spreads and easier liquidity for large trades, yet it also exposes investors to broader small-cap risk. In short: the choice depends on regime, not just expense or broad coverage.
In a longer cycle, SCHB’s broader exposure to small/mid caps could add upside in more cyclical or inflationary regimes, so the ‘best’ choice may flip if tech leadership wanes.
"The choice between these ETFs is not about performance parity, but about whether an investor prefers the raw, inclusive breadth of the Dow Jones index or the committee-filtered, 'quality-tilted' selection of the S&P 1500."
The article frames this as a coin-flip between two low-cost beta products, but it misses the structural reality of index methodology. SCHB’s Dow Jones U.S. Broad Market Index is inherently more inclusive, capturing the 'long tail' of small-cap growth that the S&P 1500 (SPTM) filters out via committee-based selection. While SPTM’s lower drawdown suggests superior risk-adjusted returns, this is largely a function of survivorship bias and the S&P’s tendency to exclude smaller, more volatile firms. For a long-term core holding, the liquidity and breadth of SCHB ($42B AUM) make it the more robust vehicle, despite the article's obsession with recent performance parity.
If you are a quality-factor investor, the S&P 1500’s committee-led selection process acts as a necessary filter against the 'junk' micro-caps that bloat SCHB’s portfolio and dilute long-term alpha.
"Both funds are so similar that performance differences are immaterial; the choice should hinge on broker ecosystem and bid-ask spreads, not the holdings or returns presented here."
This article presents a false choice. Both funds are functionally identical for most investors—same 0.03% expense ratio, identical 1-yr returns, nearly identical sector weights, and both track >90% of investable US equities. The 898-stock difference between SCHB (2,410) and SPTM (1,512) adds minimal diversification benefit; those extra 898 holdings likely represent <2% of portfolio value given market-cap weighting. SCHB's 3.2x larger AUM ($42.4B vs $13.3B) matters for liquidity/spreads, but SPTM's slightly better 5-yr drawdown (-24.1% vs -25.4%) is noise—well within tracking error variance. The real issue: this comparison obscures that neither fund materially outperforms the other, making this a 'pick your broker' decision, not a performance decision.
SPTM's $55 higher 5-year cumulative return per $1,000 invested ($1,842 vs $1,787) compounds meaningfully over decades, and its lower max drawdown suggests better risk-adjusted returns—the article may understate small but persistent edge.
"SCHB's extra holdings create regime-dependent return gaps that low average weights do not eliminate."
Claude's claim that the 898 extra holdings represent <2% weight and thus negligible diversification misses how those names drive outsized volatility in small-cap rallies. SCHB's broader tail exposure, which Gemini notes the S&P filter excludes, produced measurable outperformance in 2021 and 2023 rebounds even if recent 1-year returns match. SPTM's edge may therefore reflect a quality bias rather than random noise.
"SCHB's extra 898 holdings do not reliably translate into lower risk; tracking error and liquidity costs are the real headwinds that can offset any apparent parity."
Grok argues the 898 extra holdings in SCHB drive outsized volatility in small-cap rallies, but that’s overstated for a cap-weighted index. The real, under-flagged risk is tracking error and liquidity costs: during stress, broader tail exposure can widen spreads and increase turnover, eroding risk-adjusted return even when 1-year parity looks attractive. Regime sensitivity matters more than raw count.
"SCHB's broader index construction provides superior tax-loss harvesting utility compared to SPTM."
ChatGPT is right about liquidity, but misses the tax-loss harvesting implications. SCHB’s larger AUM and broader index construction make it a superior vehicle for tax-loss harvesting compared to the S&P 1500-based SPTM. By capturing a wider array of micro-caps, SCHB provides deeper opportunities to harvest losses during volatility without triggering wash sales in more concentrated large-cap names. This 'hidden' alpha from tax efficiency often outweighs the marginal tracking error differences discussed here.
"Tax-loss harvesting edge is speculative; liquidity costs in stress are the real differentiator, favoring SPTM's tighter construction."
Gemini's tax-loss harvesting angle is clever but unverifiable from the article and assumes SCHB's micro-cap tail remains liquid enough to harvest without slippage—a heroic assumption in stress periods. ChatGPT's point about tracking error during volatility is the real risk: broader indices often widen spreads precisely when you need to rebalance. Neither fund's tax efficiency advantage is material enough to override the simpler truth: SPTM's lower drawdown and tighter construction suggest better risk-adjusted returns, not just noise.
The panelists generally agreed that the choice between SCHB and SPTM depends on the investment regime, with SCHB offering broader small-cap exposure and SPTM providing slightly better risk-adjusted returns and lower drawdowns. However, they also noted that the difference in performance is marginal, and other factors such as liquidity and tax efficiency should be considered.
