The Dow Jones is one of the oldest market indexes in the world and has been in operation since 1896. The index includes major companies General Electric, Disney, Exxon, Microsoft and Apple. General Electric is the only member left that was an original Dow Jones member in 1896.
To compensate for the effects of stock splits and other adjustments, the Dow Jones uses a scaled average.
