NEW YORK -- A Citi analyst on Tuesday upgraded Interpublic Group of Cos. to "Buy" from "Neutral," saying that the company is poised to rebound next year after a tough 2012.

THE BACKGROUND: Interpublic, along with other advertising companies, had a rough time this year. In July the New York-based holding company for advertising and marketing agencies said its second-quarter net income fell 3 percent, hurt by some U.S. account losses in 2011 and the stronger dollar.
