How to Buy the S&P 500: A Step-by-Step Guide
7 min read · Updated July 6, 2026
One of the most common surprises for new investors: you search your brokerage app for "S&P 500" or its ticker ^GSPC — and there is nothing to buy. That is because the S&P 500 is an index, a calculated number that measures 500 large U.S. companies together. You can’t buy the thermometer; you buy a fund that copies it.
The good news is that buying that fund is one of the simplest transactions in investing, and it is how millions of people own a slice of the 500 biggest U.S. companies in a single purchase. This guide walks through it step by step.
Why you can’t buy ^GSPC directly
The S&P 500 index (^GSPC) is a measurement, published by S&P Dow Jones Indices. It has no shares, no price you can pay, and no way to own it — the same way you can’t buy "the average temperature."
What you can buy is an index fund or ETF (exchange-traded fund) that holds all 500 companies in the same proportions as the index. Its price moves almost identically to the index, minus a tiny annual fee.
The main S&P 500 ETFs
Four U.S.-listed ETFs dominate, and they all do the same job: VOO (Vanguard, 0.03% annual fee), IVV (iShares, 0.03%), SPLG (SPDR Portfolio, 0.02%), and SPY (the original SPDR fund, 0.09%).
The practical differences: SPLG has the lowest share price (under $100), which makes it the easiest starting point if your broker doesn’t offer fractional shares. VOO, IVV, and SPLG are the cheapest to hold long-term. SPY is the most famous and most heavily traded — that matters to professional traders, not to long-term holders.
A 0.03% expense ratio means you pay about $3 per year for every $10,000 invested — deducted automatically from the fund’s value, never billed to you.
Step-by-step: placing your first order
Step 1 — Fund your brokerage account and wait for the cash to show as available (bank transfers can take a day).
Step 2 — Search the ticker (for example SPLG or VOO) in your broker’s search bar. Confirm the result says "ETF" and the exchange is NYSE Arca — not a similarly named derivative or CFD.
Step 3 — Tap Buy and pick an order type. A market order buys instantly at the current price and is fine for large ETFs like these. A limit order lets you set a maximum price you’ll pay — a good habit, and it usually fills within seconds anyway.
Step 4 — Enter the amount: a number of shares, or a dollar amount if your broker supports fractional shares (many let you buy "$100 of VOO").
Step 5 — Confirm. You now own a slice of all 500 companies. There is nothing to manage afterwards — no expiry, no renewal.
Best done during U.S. market hours (9:30 a.m.–4:00 p.m. New York time, Monday–Friday). Orders placed outside those hours wait for the open or fill at less predictable prices.
If you invest from outside the U.S.
Many European brokers cannot sell U.S.-domiciled ETFs to retail customers because of EU rules (PRIIPs). If VOO or SPY won’t appear in your search, look for the UCITS versions instead: VUSA (Vanguard S&P 500 UCITS) or CSPX (iShares Core S&P 500 UCITS).
They track the same index; the differences are the exchange they trade on, the currency, and how dividends are handled (CSPX reinvests them automatically, VUSA pays them out).
After you buy: the boring part is the strategy
An S&P 500 ETF is designed to be held, not traded. The most common approach is dollar-cost averaging — investing a fixed amount monthly regardless of price — which removes the impossible task of timing the market.
Expect volatility: the index has historically dropped 10% or more every couple of years and 30%+ in serious bear markets, while still compounding strongly over decades. The investors who did best were usually the ones who kept buying through the drops.
Frequently asked questions
Why can’t I find ^GSPC in my brokerage account?
^GSPC is the ticker for the S&P 500 index itself — a calculated number, not a security. You can’t buy an index directly. Search instead for an ETF that tracks it, such as VOO, IVV, SPLG, or SPY.
What is the difference between VOO, IVV, SPLG, and SPY?
They all track the S&P 500 and behave almost identically. VOO and IVV charge 0.03% per year, SPLG 0.02%, and SPY 0.09%. SPLG has the lowest price per share; SPY is the most traded. For long-term holding, any of the low-fee options works.
How much money do I need to buy the S&P 500?
If your broker supports fractional shares, you can start with a few dollars. Otherwise, one share of SPLG (typically under $100) is the lowest-cost entry among the major S&P 500 ETFs.
Can I buy the S&P 500 from Europe?
Usually not the U.S.-listed funds — EU rules block them for retail investors. Search for the UCITS equivalents instead: VUSA or CSPX. They track the same index and are sold by European brokers.
