What is the S&P 500®?

The S&P 500 (aka the Standard & Poor’s 500 index) is a collection of about 500 of the largest publicly traded companies in the US. To be included, a company must meet a set of criteria including that their market capitalization—or the number of shares multiplied by the share price—must be over a certain amount. While it isn’t possible to buy this stock market index directly, you could invest in an index fund that seeks to replicate the index’s performance. It’s also possible to buy each of the individual component stocks; however, this can require a lot more upfront work and maintenance to keep your portfolio’s balance in sync with the S&P 500 over time.

How to invest in the S&P 500 companies

If you’re interested in investing in the companies that make up the S&P 500, here are the steps you could take:

1. Choose a financial institution

If you’re not already working with a brokerage firm, ask these 5 questions to help choose a broker.

2. Choose and open an investment account

Before you can make a trade, you need an account. Here are some of your choices.

If you don’t already have one of these accounts, follow your institution’s instructions for opening one. Then be sure to fund it so you have money for buying investments. For instance, you could link your bank account to the investing account and transfer cash in.

3. Decide how you want to invest

There are a variety of ways that you can invest in the S&P 500 companies, including:

  • Funds

    Mutual funds and exchange-traded funds (ETFs) are baskets of investments you can buy at once, potentially offering exposure to a number of stocks or other investments and helping to diversify your portfolio. Mutual funds are bought and sold at their 4 p.m. ET price, or net asset value (NAV). You can also trade ETFs throughout the day, but their prices will fluctuate based on market activity. In exchange for a fund manager managing the fund, mutual funds and ETFs charge fees. Index funds designed to match the performance of the S&P 500, rather than aim to outperform it, could be lower-cost than a fund that’s actively managed in an effort to beat market benchmarks.

  • Direct indexing product

    Instead of buying a pre-made basket like a mutual fund or ETF, a direct indexing provider will go to the market and buy all the individual stocks for you to hold in your own personal account. So instead of owning shares of a mutual fund or ETF that tracks the S&P 500, you directly own shares of the 500 stocks in your own account. A direct indexing service will do the work for you to automatically rebalance the account, trade, and track the S&P 500 index or index of your choosing over time. Direct indexing providers will typically charge a management fee to manage the account for you.

  • Individual stocks

    If you’d like to mimic the S&P 500 index performance on your own, you could buy individual stocks in amounts equal to their weighting in the S&P 500—because companies with larger market capitalizations (like Apple or Microsoft) have a greater influence on the index’s performance. Given the relatively low costs to invest in an S&P 500 index managed product, this approach is generally not recommended since it also takes a lot of work to implement and manage.

Potential advantages of investing in the S&P 500 companies

S&P 500 returns have been relatively strong over time

Over the last century, the S&P 500 has had average annualized returns of about 10%.1 Of course, returns have varied by year and historical returns are no guarantee of future performance.

Investing in the S&P 500 companies could be easy

With S&P 500 index mutual funds, ETFs, and direct indexing products, you can create a large portfolio of hundreds of stocks with a single purchase.

It can provide diversification

Diversification is the practice of spreading your investments around so that your exposure to any one type of asset is limited. The S&P 500 is spread across different sectors and industries, so investing in all these companies can be a way to diversify with this asset class. This could help protect your investment mix because you don’t have all your money in one sector or individual stocks. But keep in mind that, even though investing in the S&P 500 diversifies the stocks within your portfolio, it doesn’t diversify across asset classes.

There are generally lower fees to invest

Index funds tracking the S&P 500 typically have lower fees than some other funds, such as actively managed funds. With index funds, a fund manager seeks to simply replicate an existing index whereas they must build a basket of stocks from scratch and routinely rebalance actively managed funds.

What to watch for with investing in the S&P 500 companies

It involves risk

The stock market can be volatile, meaning it can go up and down dramatically over periods of time. That means you could face considerable losses in the short term, even with S&P 500 stocks. During the 2022 bear market, for instance, the S&P 500 fell almost 20%.3 Make sure you only invest what you can afford to lose and you have money elsewhere for your needs and emergency savings.

It only includes large companies

Since the S&P 500 only focuses on large-cap companies, it excludes small and medium-sized companies that could have greater growth potential. It also doesn’t include foreign stocks, bonds, and other asset classes.

It comes with fees for mutual funds, ETFs, and direct index providers

Index funds are usually cost-effective compared to actively managed funds, but they still take a small cut of your investment money. If you buy individual stocks instead, keep in mind that they may also charge trading fees.

Investing involves risk, including risk of loss.

Past performance is no guarantee of future results.

ETFs are subject to market fluctuation and the risks of their underlying investments. ETFs are subject to management fees and other expenses.

Exchange-traded products (ETPs) are subject to market volatility and the risks of their underlying securities, which may include the risks associated with investing in smaller companies, foreign securities, commodities, and fixed income investments. Foreign securities are subject to interest rate, currency exchange rate, economic, and political risks, all of which are magnified in emerging markets. ETPs that target a small universe of securities, such as a specific region or market sector, are generally subject to greater market volatility, as well as to the specific risks associated with that sector, region, or other focus. ETPs that use derivatives, leverage, or complex investment strategies are subject to additional risks. The return of an index ETP is usually different from that of the index it tracks because of fees, expenses, and tracking error. An ETP may trade at a premium or discount to its net asset value (NAV) (or indicative value in the case of exchange-traded notes). The degree of liquidity can vary significantly from one ETP to another and losses may be magnified if no liquid market exists for the ETP's shares when attempting to sell them. Each ETP has a unique risk profile, detailed in its prospectus, offering circular, or similar material, which should be considered carefully when making investment decisions.

Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments. Investing in stock involves risks, including the loss of principal.
