One of the major indices in the U.S. stock market, the Dow Jones Industrial Average, or DJIA, is a measure of the value of how many companies?

The DJIA measures the stock performance of 30 large companies on the exchange, and it was first calculated on May 26, 1896. Second only to Dow Jones Transportation Average, the DJIA is measured by taking the sum of the stock prices of the companies included in the index, divided by a certain changeable factor, which is around .15.
