The Dow Jones and S&P 500 are both stock market indices designed to track the performance of markets. The Dow Jones is composed of 30 hand-picked large-cap stocks in the US, while the S&P 500 is 500 large stocks in the US. Both of these indices are selected by committees, with some criteria that a company must fit to be eligible — despite this, these indices are very different in their value, size and diversification.
What’s the difference between the Dow Jones and the S&P 500?
The S&P 500 is a collection of 500 large-cap stocks on US exchanges while the Dow Jones is a collection of just 30 stocks.
Other than the number of stocks, a huge difference between the 3 is the way each index is weighted. The Dow Jones is price-weighted so stocks with higher prices have a larger impact on the whole index. The S&P 500 is a float-adjusted market-cap-weighted index. This means that each company’s size is measured by the stock price multiplied by the total number of outstanding shares and adjusted for a public float. Companies with a higher market cap have a larger impact on the overall index.

Is it better to invest in the S&P 500 or the Dow Jones?
Finder expert Zoe Stabler answers
As you can see from the chart above, these indices have historically performed very similarly. You’ll notice that the market capitalisation of the S&P 500 is around 3 times that of the Dow Jones despite having more than 16 times the number of stocks on the index.
This means that the Dow Jones is a bit more concentrated. Neither index is better. The one you choose would depend on the stock breakdown you’re interested in. As it’s only got 30 stocks, the Dow Jones wouldn’t create as much diversification as you might be looking for in an investment. The S&P 500 has plenty of diversification available.
