Initial components
Dow calculated his first average purely of industrial stocks on May 26, 1896, creating what is now known as the Dow Jones Industrial Average. Of the original 12 industrials, only General Electric currently remains part of that index.[11] The other 11 were:[12]
American Cotton Oil Company, a predecessor company to Bestfoods, now part of Unilever.
American Sugar Company, became Domino Sugar in 1900, now Domino Foods, Inc.
American Tobacco Company, broken up in a 1911 antitrust action.
Chicago Gas Company, bought by Peoples Gas Light in 1897, now an operating subsidiary of Integrys Energy Group.
Distilling & Cattle Feeding Company, now Millennium Chemicals, formerly a division of LyondellBasell, the latter of which recently emerged from Chapter 11 bankruptcy.[13]
Laclede Gas Company, still in operation as the Laclede Group, Inc., removed from the Dow Jones Industrial Average in 1899.
National Lead Company, now NL Industries, removed from the Dow Jones Industrial Average in 1916.
North American Company, an electric utility holding company, broken up by the U.S. Securities and Exchange Commission (SEC) in 1946.
Tennessee Coal, Iron and Railroad Company in Birmingham, Alabama, bought by U.S. Steel in 1907; U.S. Steel was removed from the Dow Jones Industrial Average in 1991.
U.S. Leather Company, dissolved in 1952.
United States Rubber Company, changed its name to Uniroyal in 1961, merged with private B.F. Goodrich in 1986, bought by Michelin in 1990.
you’ve got a point but the DOW just ain’t what it used to be, kind of like the lower Manhattan financial district, not much left along the old ‘Wall St.’
