AbbVie (NYSE:ABBV) has struggled to keep up with its industry peers this year. The stock's down double-digit percentages in 2014 despite strong sales growth from top drug Humira, the immunology therapy that made up around 58% of AbbVie's total revenue in its most recent quarter. AbbVie's reliance on Humira has brought criticism from some stock observers, although the drug has patent protection until 2016-and even then, generic drugmakers have been hard-pressed to develop copies of biologic drugs such as Humira in the past, so expect AbbVie's top therapy to continue producing top-notch revenue for some time.

However, savvy investors keep an eye on the long term -- and AbbVie's doing the same. The company's gearing up for the future with a pipeline sporting several promising drugs. AbbVie's oral hepatitis C compound has garnered the most attention as the company's entrant into the race to secure a slice of what could amount to a $20 billion market, but it has more potential blockbusters under development that could deliver for investors in the future.
