　　Historical Background

　　The Dow Jones Industrial Average was first introduced in 1896 by Charles Dow, an economist at the Wall Street Journal. It was initially composed of 18 industrial companies and was based on their share prices. Over time, the index has grown to include more than 30 companies, and it remains one of the most important indices in the world.

The index is calculated using a formula that takes into account the closing prices of each company's shares on a specific date.

Companies with larger market caps receive a higher weight, while those with smaller market caps receive a lower weight.
