Yes, you can invest in the S&P 500 through funds or individual stocks

The S&P 500 is a list of 500 large U.S. companies tracked by Standard & Poor's. You cannot buy "the S&P 500" itself as a single thing, but you can own all 500 companies at once by buying an S&P 500 index fund or exchange-traded fund (ETF). You can also buy individual stocks of companies on that list. Most people who want S&P 500 exposure choose a fund because it spreads the money across all 500 companies with one purchase.

The three main routes are index mutual funds, index ETFs, and individual stocks. Index funds and ETFs track the S&P 500 by holding the same 500 companies in the same proportions. Individual stocks let you pick and choose, but you would need to buy all 500 separately to match the index. Each route has different costs, tax treatment, and account types where you can hold them.

Key Takeaways

  • S&P 500 index funds and ETFs hold all 500 companies, so one purchase gives you exposure to the entire index.
  • Index funds are mutual funds you buy through a brokerage or retirement account; ETFs trade like stocks on an exchange during market hours.
  • Expense ratios (the annual fee to own the fund) range from under 0.04% to 0.20% or higher depending on the fund provider and whether the fund is actively or passively managed.
  • You can hold S&P 500 funds in taxable brokerage accounts, IRAs, 401(k)s, and most other investment accounts.
  • Individual stocks from the S&P 500 list let you own pieces of specific companies, but you would need to buy all 500 to match the index's diversification.

S&P 500 index funds versus ETFs

An index mutual fund is a fund that buys and holds the same 500 companies in the S&P 500. You buy shares of the fund itself, not the individual companies. The fund manager rebalances it to match the index, and you can buy or sell shares once per day at the closing price. Common S&P 500 index mutual funds include Vanguard 500 Index Fund, Fidelity 500 Index Fund, and Schwab U.S. Index Fund.

An exchange-traded fund (ETF) is similar but trades like a stock during market hours. You can buy and sell shares throughout the day at changing prices, not just at the daily closing price. Popular S&P 500 ETFs include SPY, IVV, and VOO. ETFs often have lower expense ratios than mutual funds, though some mutual funds charge very little as well.

For most investors, the difference between a low-cost index fund and a low-cost ETF is small. The choice often comes down to which brokerage you use and whether you prefer buying once per day (mutual fund) or during trading hours (ETF). Both hold the same 500 companies and track the index closely.

Expense ratios and what they cost you

The expense ratio is the annual percentage fee you pay to own the fund. It is deducted from the fund's value automatically, so you do not see a bill. A fund with a 0.04% expense ratio costs $4 per year on a $10,000 investment. A fund with a 0.50% expense ratio costs $50 per year on the same $10,000.

Passive S&P 500 index funds typically charge between 0.03% and 0.20% per year. Actively managed funds that try to beat the S&P 500 often charge 0.50% to 1.00% or more. Over decades, even small differences in expense ratios compound. A 0.04% fund and a 0.50% fund tracking the same index will have meaningfully different balances after 20 or 30 years, all else equal.

You can find the expense ratio in the fund's prospectus or on the brokerage website where you would buy it. Compare expense ratios across funds before you decide, because lower costs mean more of your money stays invested.

Where you can hold S&P 500 investments

You can buy S&P 500 index funds or ETFs in most types of investment accounts. A taxable brokerage account has no contribution limits and no withdrawal restrictions, but you owe capital gains tax when you sell at a profit. A traditional IRA lets you deduct contributions from your taxes now and pay tax on withdrawals in retirement. A Roth IRA takes after-tax contributions but lets you withdraw gains tax-free in retirement.

A 401(k) or similar workplace retirement plan often offers S&P 500 index funds as one of the investment choices. Some employers match contributions, which is information programs. A SEP IRA or Solo 401(k) is for self-employed people and has higher contribution limits than a regular IRA.

The account type you choose affects how much you can contribute each year, when you can withdraw without penalty, and how your gains are taxed. If you have access to a 401(k) with an employer match, that is usually the first place to invest because the match is when ready return on your money.

Buying individual S&P 500 stocks instead of a fund

You can buy individual stocks of any company on the S&P 500 list through a brokerage. This gives you ownership in specific companies rather than all 500 at once. If you believe certain companies will outperform the index, you might choose individual stocks. However, picking individual stocks requires research and carries more risk because your money is concentrated in fewer companies.

To match the S&P 500's diversification by buying individual stocks, you would need to buy all 500 companies in the same proportions the index uses. That would be expensive and impractical for most investors. Most people who buy individual stocks do so alongside index funds, not instead of them.

Individual stocks have the same tax treatment as funds when held in taxable accounts — you owe capital gains tax when you sell at a profit. In retirement accounts like IRAs and 401(k)s, individual stocks work the same way as funds: contributions and growth are tax-deferred or tax-free depending on the account type.

Minimum investments and account opening

Most brokerages have no minimum to open an account or buy an index fund or ETF. Some brokerages require a minimum deposit to open, but many do not. You can start with as little as $1 or $100 depending on the brokerage. Fractional shares are now common, meaning you can buy a partial share if you do not have enough for a whole share.

Opening a brokerage account takes 10 to 15 minutes online. You provide your name, address, Social Security number, and employment information. The brokerage verifies your identity and opens the account. You then link a bank account to transfer money in, and you can buy funds or stocks when ready.

For retirement accounts like IRAs, the process is similar but you also choose whether you want a traditional or Roth IRA. The brokerage will ask about your income and filing status to make sure you are within the limits for that account type.

Tax treatment of S&P 500 investments

In a taxable brokerage account, you owe capital gains tax on profits when you sell. If you hold the investment for more than one year, you pay long-term capital gains tax, which is usually lower than ordinary income tax. If you hold it for one year or less, you pay short-term capital gains tax at your ordinary income tax rate. You also owe tax on any dividends the fund or stocks pay, though S&P 500 companies typically pay modest dividends.

In a traditional IRA, you do not owe tax on gains or dividends while the money is in the account. You pay ordinary income tax on withdrawals in retirement. In a Roth IRA, you pay no tax on gains or withdrawals in retirement, but contributions are made with after-tax dollars. In a 401(k), growth is tax-deferred like a traditional IRA, and withdrawals are taxed as ordinary income.

The tax advantage of retirement accounts is one reason they are often the first place to invest. If you have maxed out your retirement account contributions, a taxable brokerage account is the next step, and you can use tax-loss harvesting or strategic timing of sales to reduce your tax bill.

Frequently Asked Questions

What is the difference between SPY, IVV, and VOO?

All three are S&P 500 ETFs that track the same index and hold the same 500 companies. SPY is the oldest and most traded. IVV and VOO have slightly lower expense ratios. The differences are small; the choice usually comes down to which brokerage you use or personal preference. All three will give you nearly identical returns.

Can I lose money investing in an S&P 500 fund?

Yes. The S&P 500 goes up and down with the stock market. If you sell during a downturn, you could have less money than you put in. However, if you hold for decades, the historical trend is upward. Short-term losses are normal; long-term investors typically recover and gain.

Do I need a lot of money to start investing in the S&P 500?

No. Most brokerages let you open an account with no minimum and buy fractional shares for as little as $1. You can start small and add money over time. Many people use automatic monthly transfers to invest regularly, which is called dollar-cost averaging.

Should I buy an index fund or pick individual stocks?

Index funds are simpler and require less research. Individual stocks let you bet on specific companies but carry more risk. Many investors do both: hold an index fund as a core holding and buy individual stocks with a smaller portion of their money.

Can I hold S&P 500 funds in a 401(k)?

Yes. Most 401(k) plans offer S&P 500 index funds as one of the investment choices. Some plans offer them as mutual funds, others as ETFs. Check your plan's investment menu to see which S&P 500 options are available to you.
