Apple of California will replace AT&T in the Dow Jones Industrial Average after the close of trading on March 18, Reuters reported this morning. The famed Dow Jones Industrial Average is indicative of the overall market health so Apple joining and replacing the nation's second-largest carrier on the index is certainly an encouraging sign for the economy.
Because the Dow is a weighted average of absolute stock price (unlike other indices), Apple was unable to join the Dow until its seven-to-one stock split, which took place in June of last year.
