The highest-yielding company in the Dow is Citigroup ( C), a stock that offers a 7.3% dividend yield. Citigroup ended 2007 down nearly 50% after the financial services firm suffered record losses from writedowns in its subprime-lending division. Former CEO Chuck Prince was fired in 2007, and the board promoted Vikram Pandit, former hedge fund manager at Old Lane, to the CEO position. By all accounts, Citigroup is a poorly run, mismanaged firm with no real direction. However, all that really matters here is if 2008 will be better than 2007 in terms of stock performance. Value investors Ahmet Okumus of Okumus Capital and Edward Lampert of ESL Investments appear to think so. In fact, both funds likely will press for representation on the board of Citigroup in 2008 and perhaps plead for a breakup of the company.
