The Dow Jones Industrial Average also known as the Dow 30 and informally known as the Dow Jones or The Dow is one of a few American stock market indices. The Dow Jones was compiled to gauge the performance of the industrial sector of the American stock market and is the second oldest American-Market index, after the Dow Jones Transportation Average.

The “industrial” in its name is purely historical and since its creation many of the 30 companies that make-up the index have little or nothing to do with traditional heavy industry.
