The Only Sector With No Representation in the Dow Jones Industrial Average

There's arguably no stock index more widely followed, or considered to be more iconic, than the Dow Jones Industrial Average (DJINDICES: ^DJI). The 30-stock index, comprised primarily of U.S. multinational juggernauts from a variety of sectors, has been around for 121 years and counting, making it the second-oldest index behind only the Dow Jones Transportation Index. Having that much history naturally makes the Dow an index that retail investors and industry pundits watch closely.

But the Dow is far from a perfect index. In fact, it might be just as dated as the rotary phone.
