In an effort to help the 4-to-1 stock split by Visa (NYSE: V), Apple (NASDAQ: AAPL) will replace AT&T (NYSE: T) on the Dow, according to Apple Insider. The change will take place Wednesday, March 18 at closing and come into effect Thursday March 19 at opening, Apple Insider reported. "As the largest corporation in the world and a leader in technology, Apple is the clear choice for the Dow Jones Industrial Average, the most recognized stock market measure," Managing Director and Chairman of the Index Committee at S&P Dow Jones Indices David M. Blitzer said. Apple Insider commenter spamsandwich said: “I'm no expert, but there are funds that are based on these composite indexes. Could mean AAPL gains more investors, for one. Second, AAPL's volatility may lessen as it becomes more widely held. This seems to me to be a very odd move by Dow Jones and it will be interesting to see how AAPL actually does influence the index. Perhaps a little more volatility is what they need since their composite growth versus Apple's growth has been dismal.”
