How to invest in the S&P 500

5 easy steps to start investing in the S&P 500

Billionaire investor Warren Buffett has said “for most people, the best thing to do is to own the S&P 500 index.” So what is the S&P 500 and how do you invest?

How to invest in the S&P 500 for beginners

  1. Choose a trading platform. Compare things like fees and tradable assets. For example, if you want to invest in an S&P 500 mutual fund, make sure the broker you choose offers mutual fund investing.
  2. Open and fund an account. Complete an application with your personal details and link a bank account for funding.
  3. Research investment options. Find the stock, ETF or mutual fund by name or ticker symbol and research it before deciding if it’s a good investment for you.
  4. Purchase the security. Buy your desired number of shares with a market order or use a limit order to delay your purchase until the stock reaches a desired price.
  5. Monitor your investment. Periodically check on your investment to make sure it’s aligned with your objectives.

What is the S&P 500?

The S&P 500 is a market capitalization-weighted stock market index of over 500 leading US companies in the most prominent industries of the US economy, traded on either the New York Stock Exchange (NYSE) or Nasdaq.
The index was first introduced in 1957. Today, the S&P 500 covers approximately 80% of available market cap and is widely regarded as the best single measure of US stock market performance.

What companies are in the S&P 500?

The S&P 500 includes some of the most recognizable and popular stocks in the world. The top ten constituents make up nearly 27% of the entire S&P 500, with Apple alone representing 6% of the total index. This is why when Apple is down, the entire index feels it. The top 10 constituents of the S&P 500 by index weight as of November 30, 2022, are:

Apple (AAPL)Information technology
Microsoft (MSFT)Information technology (AMZN)Consumer discretionary

Historical performance of the S&P 500

2 ways to invest in the S&P 500

You can’t invest directly in the S&P 500, as it only tracks the performance of its constituent stocks. But there are a couple ways you can invest in S&P 500 companies.

1. Buy an index fund that tracks the S&P 500

The easiest way to invest in the S&P 500 is to invest in either an exchange-traded fund (ETF) or mutual fund that tracks the S&P 500. Funds that track an index like the S&P 500 are known as index funds.
Index funds are designed to track the performance of and achieve approximately the same return as an underlying index, in this case the S&P 500. S&P 500 index funds will have exposure to the top constituents — Apple, Microsoft, Amazon, etc. These funds are a great way to add instant diversification to your portfolio at a low cost.
Since most S&P 500 index funds should in theory achieve nearly similar returns, a fund’s performance may not be the most important factor when deciding which to invest in. Investors should pay closer attention to expenses, which are what will vary the most between funds.

2. Buy S&P 500 stocks individually

An alternative way of investing in the S&P 500 is to buy individual stocks in companies listed in the index. This would mean buying and owning individual shares of the FAANG companies like Facebook (Meta), Apple, Amazon and so on.
