What's inside
SPTM seeks to replicate the S&P Composite 1500 Index, providing exposure to 1,511 U.S. stocks across all market capitalizations. Its sector mix leans heavily toward technology (making up 34% of the fund), followed by financial services (13%) and consumer cyclical (11%).
The top three holdings — Nvidia, Apple, and Microsoft — collectively account for nearly 20% of assets, highlighting the fund's tilt toward mega-cap tech. With a 25-year track record, SPTM is a seasoned option for broad U.S. market coverage.
VTI, in contrast, tracks the CRSP US Total Market Index and holds over 3,500 stocks, spanning large-, mid-, and small-cap names. Its sector allocation is similar, with technology at 33%, financial services at 13%, and consumer cyclical at 11%. The top holdings mirror those of SPTM, reflecting the current dominance of tech giants in U.S. equity indexes.

What this means for investors
VTI and SPTM both provide broad, low-cost access to the entire U.S. stock market. They’re virtually identical in most ways, with similar sector allocations, top holdings, expense ratios, dividend yields, betas, and max drawdowns.
Their 12-month total return is nearly identical as well, though SPTM has marginally outperformed VTI over the last five years.
The two main differences between them are the number of holdings and assets under management (AUM). VTI holds around 2,000 more stocks than SPTM, and although that hasn’t necessarily translated into differences in performance or risk profile, it can be an advantage for investors seeking maximum diversification.
VTI also has a higher AUM, providing greater liquidity. This may not affect everyday buy-and-hold investors, but larger funds can make it easier to buy or sell large amounts without affecting the ETF’s share price.
Investors looking for a core U.S. equity holding may find either ETF a strong fit, with the choice coming down to personal preference for fund size or index coverage.
