4. How Is S&P 500 Index Different From Other Indices? S&P 500 vs. Dow Jones Industrial Average vs. Nasdaq Composite

The value of a market measure is the result of a calculation. It differs depending on the methodology that a given index uses. And the differences between indices can be significant.

The Standard & Poor’s 500 and Nasdaq Composite indices are weighted based on the stock’s free float (the shares of a given company that are open to public trading). This, in turn, means that companies with the highest value of shares available for trading have the most tremendous weight. This is because the indices don’t include these companies. Investors seeking to invest in these companies must look beyond the S&P 500 Index and Nasdaq Composite.

On the other hand, the DJIA (Dow Jones Industrial Average) is more focused on price per share, giving more weight to stocks with higher share prices. Below, you can learn more about the most significant differences between these indices:

The weighting methodology – S&P 500 and Nasdaq Composite use the same methodology for assigning weights to companies in their indices. Meanwhile, the Dow Jones Industrial Average gauges the value of each company by weighing their stock prices.

The selection criteria – S&P 500 Index and Nasdaq select constituents based on the total dollar market value of their shares of stock. Dow, on the other hand, uses a combination of qualitative and quantitative models to determine the value of a given stock.

Different coverage universes – The DJIA covers 30 blue chip constituents. At the same time, S&P 500 and Nasdaq include a broader scale of companies from various industries.

5. A Measure of the Largest Companies‘ Share Prices

In summary, markets see the Dow Jones Industrial Average as a blue-chip index. Similar to the S&P 500 Index, it gauges the weight of the largest companies. However, it’s primarily focused on share prices rather than the total market value of a given company’s shares.

S&P 500 Index is the primary benchmark for determining the market’s condition. In fact, the S&P 500’s weighting in the financial sector is a big reason it has outgrown the Dow.
