Vanguard vs. State Street: Which S&P 500 ETF Puts Your Money to Work Better?

For millions of Americans, the S&P 500 is the default gateway to the stock market. It tracks the 500 largest and most influential companies in the United States, from tech giants to healthcare leaders. But when it comes to investing in that index, two funds dominate the conversation: the Vanguard S&P 500 ETF (VOO) and the State Street SPDR S&P 500 ETF (SPY). Both are massive, both track the same benchmark, and both are solid choices. The real difference comes down to cost, structure, and what kind of investor you are.

What are the key differences between VOO and SPY?

The most important distinction is cost. Vanguard charges an expense ratio of just 0.03%, while State Street charges 0.09%. That might sound small, but over a decade, it adds up. For a $10,000 investment held for 10 years, VOO would leave you with $40,596.51, about $211 more than SPY. Both funds pay a dividend yield of roughly 1%, since they hold the same underlying stocks.

There's also a structural difference. SPY is a unit investment trust (UIT), which means it must fully replicate the index and cannot reinvest dividends between distribution dates. That can create a slight cash drag during bull markets. VOO, by contrast, uses a full-replication approach but has more flexibility in how it handles cash flows.

How do the two ETFs compare on performance and risk?

Over the trailing 12 months, VOO is up 10.12% while SPY is up 10.09%. The gap widens over longer periods. Over 3, 5, and 10 years, VOO has returned 19.29%, 12.82%, and 15.04% annualized, respectively. SPY returned 19.19%, 12.76%, and 14.98% over the same periods. The maximum drawdowns are nearly identical, and both funds hold essentially the same portfolio: technology at 37%, financial services at 12%, and communication services at 10%. Their top holdings are also the same, with Nvidia at 7.6%, Apple at 7.1%, and Microsoft at 5.4%.

Which S&P 500 ETF is the better buy for long-term investors?

For the vast majority of investors, the answer is clear: Vanguard's VOO. The lower expense ratio compounds over time, and the performance history backs it up. Unless you are among the world's largest institutional investors who need SPY's slightly higher trading liquidity, the cost advantage makes VOO the smarter choice. Both funds are plenty liquid for everyday investors, so that edge rarely matters in practice.

Why does cost matter more than history?

SPY has been around since 1993, making it the older fund. VOO launched in 2010. But age alone doesn't justify a higher fee. In a market where both funds track the same index with nearly identical holdings, the only meaningful variable is cost. Lower fees mean more of your returns stay in your pocket. That's not speculation; it's math.

Frequently asked questions about VOO and SPY

Are VOO and SPY the same fund?

No, but they track the same index. Both hold roughly 500 to 505 stocks in proportions that mirror the S&P 500. The main differences are the expense ratio, the legal structure, and the launch date.

Can I lose money with either ETF?

Yes. Both funds are subject to market risk. If the S&P 500 drops, both VOO and SPY will drop with it. They are diversified, but they are not immune to downturns.

Which ETF is better for a beginner?

VOO is generally the better choice for beginners because of its lower cost. It offers the same market exposure as SPY but keeps more of your returns over time.

For those looking to build long-term wealth through broad market exposure, the choice is straightforward. Vanguard's VOO offers the same index tracking at a lower cost, and that efficiency is what makes it the better buy.
