What is the Dow Jones?

The Dow Jones Industrial Average, usually just called the Dow is a stock market index that tracks 30 large, well-established American companies. It was created in 1896 by Charles Dow and Edward Jones and is one of the oldest financial indicators still in use today.

Which companies are in it?

Companies like Apple, Goldman Sachs, McDonald's, Nike, and Boeing. The 30 companies in the Dow are selected by a committee and are meant to represent a broad cross-section of the American economy. The list changes over time as industries evolve.

How is it different from the S&P 500?

The S&P 500 tracks 500 companies and is weighted by market cap. The Dow tracks only 30 and is weighted by share price. This means a company with a higher share price has more influence on the Dow, regardless of how large it actually is. Most investors and economists consider the S&P 500 a more accurate picture of the overall market.

Why is the Dow still so famous?

Mostly history. It has been around for over a century and became deeply embedded in financial culture before better alternatives existed. When news programmes report on "the market," they often quote the Dow because it is the number most people recognise.

Should you use it as your benchmark?

The S&P 500 is generally a better benchmark for most investors. With only 30 companies, the Dow is a narrow snapshot. That said, understanding the Dow matters because you will encounter it constantly in financial news and conversation.
