Things are looking up for Citigroup. For the first time since 2006, the bank logged four consecutive quarters without a loss. Meanwhile a newly restored dividend — albeit a measly one penny per share — and a ten-for-one reverse stock split could drag its shares out of the single digits.But investors still have a lot to be wary about. The company continues to unload assets — some $108 billion worth last year alone. Add the ongoing ramifications of financial reform and the credit card act, and Citi’s top-line growth looks pretty hamstrung down the road. —P.N.
