State Street Global Advisors vs Vanguard. This article compares SPY vs VOO, State Street Global Advisor's S&P 500 ETF vs Vanguard's S&P 500 ETF.

This article compares SPY vs VOO — State Street’s SPDR® S&P 500 ETF Trust and Vanguard’s S&P 500 ETF. 

Both are passively managed index ETFs popular with passive investors looking to match market returns with yields below risk-free high-yield savings rates

Index ETFs track market indexes, such as the Dow Jones Industrial Average or the Russell 2000. 

SPY and VOO track the most widely-watched U.S. stock market index: Standard & Poor’s 500.

Both funds own shares of the 500 largest U.S. companies and pay quarterly dividends. 

Passive index ETF managers do not pick stocks. They allocate funds to all stocks in the benchmark index to track its performance. Managers receive a small fee to achieve this outcome.

Since most actively managed mutual funds do not beat their target benchmarks, many fiduciary financial planners recommend index funds and ETFs instead of actively managed funds or individual stocks.

Bottom Line Upfront (BLUF)

Before I get into the details of SPY vs VOO, it’s essential to keep the following in mind:

  • The funds are virtually identical. Don’t overthink your selection. VOO edges SPY slightly in a lower expense ratio.
  • Both funds are excellent, low-fee stock index fund options for your portfolio.
  • SPY is a State Street ETF. VOO is a Vanguard ETF. 
  • Both ETFs are available to purchase from any online broker. I recommend M1 Finance, which is best for dividend investing and dividend reinvestment. 
  • If you have an account with Vanguard or Fidelity, you can own similar mutual funds (see the mutual funds section). 

Please note that both ETFs update their prospectuses regularly. The information referenced in this article will change over time.

The best resource for both funds is the respective company’s websites.

SPY vs VOO — Benchmark Indexes

SPY and VOO track the S&P 500 Index, one of the most widely-watched stock indexes worldwide.

Visit this page for the latest information about the index.

The S&P 500 Index is a float-adjusted market cap-weighted index, meaning the largest stocks make up a proportionately high percentage of the index. Lower market cap stocks comprise a proportionately lower percentage of the index. 

A selection committee of financial market professionals chooses which stocks go into the index. The focus is primarily on large-cap stocks that are representative of the U.S. economy.

The committee does not try to “pick stocks” for market outperformance. Instead, they look at company size, stock liquidity, share float, and profitability, and it fits the index’s goal to reflect the broad, large-cap marketplace accurately.

Though the funds are nearly identical, the timing of reporting and transactions may vary, causing slight imbalances between funds. 

Mutual Fund Equivalents

Here are the closest mutual fund equivalents for both ETFs.

  • SPY = FXAIX (Fidelity)
  • VOO = VFIAX (Vanguard)

The SPY mutual fund equivalent at Fidelity is the 500 Index Fund (FXAIX). Investors with an account at Fidelity who prefer mutual funds can consider this fund an a SPY alternative.

The VOO mutual fund equivalent at Vanguard is the S&P 500 Index Fund Admiral Shares (VFIAX). Investors with an account at Vanguard who prefer mutual funds can consider this fund a VOO alternative.

Customers of online brokers that charge fees for mutual funds should use the VOO or SPY ETFs.

Mutual funds trade differently than ETFs, which trade like stocks. 

ETFs are easier to own, and the price changes throughout the day. Mutual funds only trade at the market close. 

Active investors typically use ETFs for trading purposes or to buy and hold indexes when they can’t access index mutual funds.

For example, if you have an investing account with M1 Finance, you’d invest via ETFs instead of mutual funds. If your account is with Vanguard, you may benefit from using the index fund VFIAX because it’s slightly easier to reinvest capital gains and dividends. 

Use the above resources to find the most up-to-date information regarding FXAIX vs VFIAX.

What is the Best Broker to Buy SPY or VOO?

Here are my favorite online brokers for investing in ETFs and automatically reinvesting dividends. 

Fidelity and Vanguard are excellent choices for long-term retirement investors. You’re in good hands if your IRA or employer-sponsored plan is with either broker.

I recommend another broker for a more modern user experience that can also serve your banking, borrowing, and spending needs. 

Long-term investors may prefer an online broker better for dollar cost averaging and dividend reinvestment. 

I’m a big fan of the online brokerage M1 Finance. M1 Finance is a reliable, robust, no-fee online broker for beginner and intermediate investors. It’s easy to get started.

As your investing skills and portfolio mature, M1 is one of the best platforms to scale.

They also offer an integrated checking account and low borrowing rates. Read my complete M1 Finance review here

M1 Finance does not offer mutual funds. However, ETFs are plentiful. It’s my favorite online broker for everyday investing. 

The platform is more intuitive than old-school brokers because it’s built on a modern technology platform.

You create portfolio “pies” that contain all the stocks and ETFs you want to own and in what percentages. Simply add an ETF to a pie and add funds to your account.

Deciding between SPY vs VOO depends on your preference for State Street or Vanguard.

Aside from the fund administrator, the expense ratio is the only other significant distinguisher between SPY and VOO. 

However, even a 0.06 higher expense ratio is insignificant. SPY is a widely-owned ETF with high liquidity. It’s the oldest and most well-known ETF in the U.S. Investors should be comfortable owning either fund. 

If you need a distinguisher, choose VOO over SPY because of the expense ratio. 

Otherwise, don’t overthink your selection. Returns, liquidity, and dividends will be nearly identical. 

Purchase either ETF at any commission-free online broker.
