The Vanguard Total Stock Market ETF (VTI +0.34%) and the iShares Core S&P Total U.S. Stock Market ETF (ITOT +0.33%) both aim to capture the full U.S. equity market, spanning large-, mid-, and small-cap stocks with broad sector exposure.

This comparison looks at cost, performance, portfolio makeup, and practical differences to help investors decide which may better suit a total-market approach.

What’s inside

ITOT tracks the S&P Total Market Index, covering 2,482 stocks and providing exposure to technology (31%), financial services (12%), and consumer cyclical (10%) sectors. Its largest holdings are Nvidia, Apple, and Microsoft. The fund has been in existence for over 22 years and does not employ any leverage, currency hedging, or ESG screens.

VTI, by comparison, is even broader, holding 3,503 stocks and offering similar sector weights — technology at 31%, financial services at 12%, and consumer cyclical at 10%. Its top positions match ITOT’s, though the exact weightings differ slightly. Both funds provide diversified access to the U.S. market without notable quirks or strategy overlays.

What this means for investors

VTI and ITOT are incredibly similar in most meaningful ways. They offer the same expense ratio and almost identical dividend yields, leading to no meaningful difference in fees or income.

They also have the same beta and roughly the same max drawdown, meaning they’ve experienced very similar levels of volatility over the last five years. Their one- and five-year total returns are also aligned, signalling very similar performance.

There are two key differences, however: the number of holdings and assets under management (AUM). VTI is larger on both accounts, which could give it an edge for some investors.

While both ETFs aim for broad market coverage, VTI holds over 1,000 more stocks than ITOT. To be fair, that extra diversification hasn’t necessarily translated to a difference in performance or risk profile. But for investors seeking as much exposure to U.S. equities as possible, VTI is significantly broader.

VTI also has a much larger AUM of $2 trillion compared to ITOT’s $81 billion. A greater AUM can lead to more liquidity, making it easier for investors to buy and sell large amounts at once. This may not be a deciding factor for many everyday investors, but given that it’s one of the few data points distinguishing these very similar ETFs, it’s worth considering.
