VOO vs VTI

VOOAVanguard S&P 500 ETF

VTIAVanguard Morningstar Total Stock Market ETF

In short

VOO Not a standalone ETF but a share class of Vanguard's flagship 500 Index Fund: the same roughly 500 large US companies, 0.03% a year, in a wrapper you can trade all day.

VTI The whole US stock market in one ticker: roughly 3,600 names, from mega caps down to micro caps, for three basis points. Vanguard has run this portfolio in ETF form since 2001, and it's grown into one of the largest funds anywhere.

Stated mandate

VOO The fund invests in stocks represented by the S&P 500 Index and seeks to closely track that index's return as a measure of overall U.S. stock performance.

VTI The fund aims to replicate the performance of a benchmark index that covers the entire U.S. stock market.

Why people hold it

• VOO 0.03% a year against a 0.15% median for S&P 500 trackers. On a fund this size, that fee gap is the whole product.
• Holds the index outright, all roughly 500 names, and its tracking record sits among the tightest in the S&P 500 group.investor.vanguard.com
• One of the most actively traded ETFs in the market, which tends to keep the cost of getting in and out small.
• It is the ETF share class of Vanguard's 500 Index Fund, and Vanguard is owned by its own funds, so no outside parent takes a cut.personal1.vanguard.comsec.gov

• VTI Costs 0.03% a year, half the 0.06% typical for its total-market peers.
• About 3,600 holdings, so the small and micro caps an S&P 500 fund leaves out are already in the mix.investor.vanguard.com
• Tracks its total-market benchmark very closely and trades heavily, and it sits among the strongest implementations in its peer group.
• The ETF is a share class of Vanguard's Total Stock Market Index Fund, sharing one portfolio with the mutual fund rather than running a separate copy.sec.gov

Worth knowing

• VOO Large US companies only, weighted by size, so the biggest few names carry the most weight and drive much of the move.spglobal.com
• Membership is not purely mechanical: an S&P index committee decides which companies come in and go out.spglobal.com
• SPYM tracks the same index for 0.02%. A rounding error for most, but real if cost is your only tiebreaker.

• VTI Market-cap weighted, so the biggest US companies drive the result and the thousands of small names at the bottom carry little weight.personal.vanguard.com
• All US, by design. Nothing outside the country comes with it.
• ITOT and SCHB match the 0.03% fee and BBUS runs 0.02%, so rivals deliver similar whole-market exposure for the same or less.
