What’s Inside

If you have a US stock market alert on your Google account, you must regularly see updates regarding upswings and changes in the NASDAQ Composite, S&P 500, and Dow Jones Industrial Average (DJIA).

These three major stock market indices in the US market track the performance of specific market subsets and can tap into the overall market's pulse. 

Debunking The Key US Indices

The NASDAQ Composite

A market cap-weighted index known as the tech-heavy index. While initially launched with just 100 companies, the index now includes over 3,000 big and small companies traded on the NASDAQ stock exchange. 

The S&P 500

Standard & Poor's 500 index is a collection of stocks from the top 500 companies in the US. While this large-cap stock index is capitalisation-weighted, a company's inclusion depends on other factors like earnings, industry, sector, etc. 


Known as the blue-chip stock index, the DJIA tracks the top 30 blue-chip companies with a universal presence across homes in the US. It includes Apple, Cisco, Nike, Microsoft, and others. DJIA is also the most widely quoted price-weighted index among investors. 

Comparing NASDAQ Composite Vs. S&P 500 Vs. DJIA

Here’s a quick comparison of the world’s leading live stock market indices.

Novice investors often confuse these stock indices and use the terms interchangeably. While all three measure the value of the stocks included, each follows a different methodology. The fact that they don’t move in lock-step derives from this key difference.
