NYSE:ABBV
This is a fine company. Its primary product is Humira, the most successful drug in the history of the pharmaceutical industry. It represents about 60% of AbbVie’s earnings, which means that AbbVie’s portfolio is not well diversified. This is not unusual for pharma companies. The drug will not go off patent for a few years, but the clock is ticking. The question to ask is whether the company has good replacements in the works.
