Like its Madison Ave. brethren, Interpublic is a massive advertising agency comprising a hodgepodge of companies. Unlike them, its stock proved to be a disaster over the past decade. During the booming '90s, Interpublic bought 400 companies in a 4-year span, according to Morningstar.

Many of these proved ill-fated. Interpublic spent much of the 2000s restructuring and selling off the worst ones. With that process over, investors are now waiting to see if the firm can adjust to the shifting media landscape.
