Introduction – What Is the S&P 500 Index?
The S&P 500 Index, the modern shorthand name of the Standard & Poor’s 500 Index, is simply a curated collection of the 500 largest publicly traded companies in the United States based on total market capitalization. The index as we know it today was started in 1957. It is probably the most followed stock index, including household names like Apple, Amazon, Disney, Google, Microsoft, Johnson & Johnson, etc. These components are weighted in the index by their size, with the top 10 holdings making up over 25% of the index.
Because the index comprises roughly 82% of the total U.S. stock market and spans all market sectors, it is used as a proxy and benchmark for “the market” as a whole. Whether you’re a beginner or a seasoned investor, the S&P 500 index is a reliable cornerstone of a long-term buy-and-hold investment strategy, providing broad diversification and low risk in equities. If you’ve arrived on this page, you likely already know those facts.
Now let’s look at how exactly to invest in the S&P 500 using index funds in the form of ETFs.
How To Invest in the S&P 500 – The 3 Best S&P 500 ETFs
Thankfully, to invest in the S&P 500 index, you don’t have to buy the 500 companies’ stocks individually. But you also can’t buy an index directly. You need an index fund – a fund that tracks the index. Index funds come in the form of mutual funds or ETFs (Exchange Traded Funds). The latter is now starting to replace the former.
Because the S&P 500 index is so popular, there are quite a few ETFs that track the index, hold those underlying stocks, and trade as a single security/ticker, all at low fees. By buying shares of a single fund, you can own all 500 companies in the index.
Proponents of passive, buy-and-hold index investing like Warren Buffett, Jack Bogle, and many others suggest simply finding a highly liquid, low-cost index fund to access the S&P 500 index as the core holding in one’s stocks portfolio. Below we’ll look at several of the best S&P 500 ETFs to do just that.
Since these funds employ passive replication of the index as opposed to active management, they have low fees and high liquidity. All you have to do is buy shares of one of the ETFs below through an online broker and you can say you are invested in the S&P 500.
SPY – SPDR® S&P 500 ETF Trust
SPY is the oldest, largest, most highly traded ETF, boasting nearly $300B in assets. SPDR® launched this ETF in 1993. SPY has an expense ratio of 0.09%.
IVV – iShares Core S&P 500 ETF
IVV from iShares has $200B in assets. The fund was established in 2000 and carries an expense ratio of 0.03%.
VOO – Vanguard S&P 500 ETF
Jack Bogle, considered by many to be “the father of index investing,” founded the brokerage firm Vanguard. Vanguard is famous for offering some of the cheapest index funds in the game. VOO is Vanguard’s ETF to track the S&P 500 index and was established in 2010. The fund has over $500B in assets and an expense ratio of 0.03%. VOO would be my choice out of these 3 funds.
Conclusion and Where To Buy These S&P 500 ETFs
All 3 of these ETFs are solid choices to invest in the S&P 500 index, so you can’t really go wrong. All 3 have very high AUM and liquidity, and all 3 have a history of tracking the index reliably and accurately. At the time of writing, IVV and VOO have the same expense ratio of 0.03% compared to 0.09% for SPY, so I would go with IVV or VOO. I’m partial to Vanguard, so I use VOO myself.
Day traders might appreciate the greater liquidity of SPY, as it’s the largest and oldest ETF out there, but buy-and-hold investors should prefer the lower fee of VOO.
All 3 of these S&P 500 ETFs should be available at any major broker. My choice is M1 Finance. The online broker has zero transaction fees and offers fractional shares, dynamic rebalancing, and a modern, user-friendly interface and mobile app. I wrote a comprehensive review of M1 Finance here.
