Dow shakeup: Citi, GM out, Travelers and Cisco in

The Dow Jones Industrial Average of 30 blue-chip stocks will have a couple new members starting next week. General Motors (GM) and Citigroup (C) will exit next Monday, to be replaced by Travelers (TRV) and Cisco (CSCO).

GM's bankruptcy Monday explains its departure. Citi is leaving because "the bank is in the midst of a substantial restructuring which will see the government with a large and ongoing stake," said Dow Jones editor-in-chief Robert Thomson in The Wall Street Journal. "We genuinely hope that once the bank has refashioned itself that we will again be able to consider it for inclusion -- Citigroup is a renowned institution, not only in this country, but around the world."
