S&P 500 index funds are passive investments that allow investors to match the performance of the S&P 500, an index featuring the 500 largest publicly traded companies in the U.S. They're ideal for investors who want to earn returns in line with the broader market but don't want to own individual stocks. Read on to learn more about these popular funds.

Three best S&P 500 index funds in 2023
These three major S&P 500 funds are extremely similar in composition since each tracks the performance of the same index:
- Fidelity 500 Index Fund (NASDAQMUTUALFUND:FXAI.X)
- Schwab S&P 500 Index Fund (NASDAQMUTUALFUND:SWPP.X)
- Vanguard 500 Index Fund Admiral Shares (NASDAQMUTUALFUND:VFIA.X)
All three are very low-cost ways to invest in the 500 companies making up the S&P 500 index. Fidelity has the lowest costs, with a 0.015% expense ratio. Schwab's is only slightly higher at 0.02%, while the Vanguard 500 Index Fund Admiral Shares has a 0.04% expense ratio.
Fidelity and Schwab offer their index funds with no minimum investment, making them very accessible to beginning investors. Meanwhile, Vanguard has a relatively low minimum investment of $3,000.
Vanguard also offers an exchange-traded fund (ETF) focused on investing in the 500 companies that comprise the S&P 500 index. The Vanguard S&P 500 ETF (VOO -0.44%) has a low minimum investment of one share (around $408 as of Sept. 15, 2023) and a low expense ratio of 0.03%. This index-fund-like product trades on a major stock exchange, allowing investors to buy and sell like they would a stock.
Each S&P 500 index fund has very closely replicated the index's performance:
| Index or Fund | 1-Year Total Return | 3-Year Annualized Return | 5-Year Annualized Return |
|---|---|---|---|
| S&P 500 Index | 15.94% | 10.52% | 11.12% |
| Vanguard 500 Index Admiral Shares | 15.89% | 10.48% | 11.08% |
| Schwab S&P 500 Index Fund | 15.90% | 10.49% | 11.09% |
| Fidelity 500 Index Fund | 11.94% | 10.52% | 11.11% |
There are negligible differences between the performances of the S&P 500 and each of these three index funds that track it. The S&P 500 outperformed each fund slightly, as would be expected when accounting for each fund's expense ratio.
At the S&P 500's rate of return, a $10,000 investment made five years ago would have grown to $16,943 by mid-2023. For comparison, a $10,000 investment in the Fidelity 500 Index Fund would have grown to $16,935 over the same five-year period, with that slight variation due to fees.
Returns
With any of these three funds, you can expect your investment to deliver a virtually identical performance to the S&P 500, minus fees. Given its lower expense ratio, Fidelity's S&P 500 index fund will likely continue to slightly outperform the funds from Schwab and Vanguard over the longer term.
Why are they popular?
Why are S&P 500 index funds popular?
An index fund is designed to mirror the performance of a stock index. An S&P 500 index fund invests in each of the 500 companies in the S&P 500 (SNPINDEX:^GSPC). It doesn't try to outperform the index. Instead, it uses the index as its benchmark and aims to replicate its performance as closely as possible.
S&P 500 funds are by far the most popular type of index fund. But index funds can be based on practically any financial market, investing strategy, or stock market sector. Index funds are popular with investors for a number of reasons. They offer easy portfolio diversification, with some funds providing broad exposure to hundreds or even thousands of stocks and bonds.
You don't risk losing all your money if one company collapses like you could with individual investments. However, you also don't have as much upside potential to the astronomical returns that can result from picking a single huge winner.
Index funds are passively managed, meaning you're not paying for someone to actively pick and choose investments. Passively managed funds result in a lower expense ratio due to lower investment management fees compared to actively managed funds.
Your money will track the market's performance
Historically, the S&P 500's annual returns have been in the 9% to 10% range. In some years, the index will lose value. For example, during the Great Recession, the S&P 500 lost about half its value. Meanwhile, the index experienced a bear market starting in early 2022, declining by more than 20% from its peak by the fall.
However, as of mid-September 2023, the index was up more than 16%. Over the long term, the index has always recovered. A 20-year investment has never resulted in a loss in the S&P 500's history.
You keep more of your investment profits in your pocket
S&P 500 index funds are low-cost investments. While active managers are likely to match or even beat the market's performance over time, their fees eat away at your returns. Because they're passive investments with low fees, S&P 500 index funds deliver returns that mirror the index's returns over the long term.
You're investing in 500 of the most profitable companies in the U.S.
The corporations represented in the S&P 500 are subject to stringent listing criteria. To join the index, a company must have a $14.5 billion market capitalization, and the sum of its past four quarters' earnings must be positive.
Each company must also get approval from an index committee. The S&P 500's largest holdings include Apple (AAPL 0.8%), Amazon (AMZN 6.83%), Microsoft (MSFT 0.59%), and Johnson & Johnson (JNJ -2.28%).
You can put your investment decisions on autopilot
The S&P 500 has a flawless track record of delivering profits over long holding periods, allowing you to invest without worrying as much about stock market fluctuations. You also don't have to research or follow individual companies.
You can simply budget a certain amount and automatically invest it on a regular schedule. This practice is known as dollar-cost averaging. Even if you do pick individual stocks, S&P 500 funds are a good foundation for your investment portfolio since you're guaranteed the returns of the stock market.

Leveraged funds
Beware of leveraged S&P 500 index funds
Be wary of leveraged funds that are advertised as S&P 500 ETFs. Leveraged ETFs use borrowed money and/or derivative securities to amplify investment returns or to bet against the index. For example, a 2x-leveraged S&P 500 ETF aims to return twice the index's daily performance. So, if the index rises by 2%, the ETF's value rises by 4%. If the index falls by 3%, the ETF loses 6%.
These leveraged products are intended to be day-trading instruments and have an inherent downside bias over the long term. In other words, a 2x-leveraged S&P 500 ETF will not return twice the index's performance over the long term.
Investing in S&P 500 index funds is one of the safest ways to build wealth over time. But leveraged ETFs -- even those tracking the S&P 500 -- are highly risky and don't belong in a long-term portfolio.
