Does Vanguard or State Street Have the Better S&P 500 ETF?

Deciding between the Vanguard S&P 500 ETF (NYSEMKT:VOO) and the State Street SPDR S&P 500 ETF (NYSEMKT:SPY) typically involves weighing the Vanguard fund's lower costs against the SPDR trust's slightly higher trading liquidity and its long-standing history.

The S&P 500 serves as the primary benchmark for the United States stock market, representing 500 of the largest and most influential companies. Investors looking for broad equity exposure often choose between VOO and SPY, two massive funds that track the same index but differ slightly in cost, age, and legal structure.

Which looks like the better buy?

These two fund giants following the S&P 500, the world's largest index, in terms of investable assets that mimic or track it in some form, have a lot of similarities, not unexpectedly.

They have identical market cap weight, with large caps constituting 80% of assets, mid caps 19%, and small caps 1%. They are both just about 99.5% in U.S. stocks, with a small bit in stocks classified as developed-world non-U.S. and emerging markets. Their maximum drawdowns are nearly identical over multiple time frames, too. Their top 10 holdings are identical, as are the amounts of each ETF dedicated to the top 10, which range from 37% to 38%.

So how to choose between these two funds? They are both plenty large,so liquidity is never a problem unless you are among the world's largest investors (I am betting you're not). The simple answer is that Vanguard and its institutionwide emphasis on low cost fund makes the difference here, especially for long-term investors.

Year-to-date, the Vanguard fund VOO is up 10.12%, while the State Street offering SPY is up 10.09%. Interestingly, in brief periods, the index funds can outperform the index because of when they buy and sell and reweight each day, but generally, both ETFs will slightly lag the index itself.

Over the 3-, 5-, and 10-year lookbacks, VOO beats SPY too. VOO has returned 19.29%, 12.82%, and 15.04% annualized. SPY returned 19.19%, 12.76%, and 14.98% over the same 3-, 5-, and 10-year periods.

Does that 0.06 percentage point decade-long performance difference matter? You would have done well with both, but $211.24 better with VOO, which would stand at $40,596.51 after 10 years with an initial investment of $10,000.

Long-term investors should choose the best long-term fund. Typically, that's the one with the lowest costs when compared to a near-identical competitor. Go with Vanguard's VOO.
