Investors may have been surprised today to find that the ticker symbol for Watson Pharmaceuticals, a well-known stalwart of the generic pharmaceutical industry, is now defunct. However, there's no need to panic: The company has simply changed its name to Actavis (AGN). Our health-care analyst Max Macaluso goes into the details behind the rebranding in this video.

Editor's note: One look at the statistics box that enters the video at 19 seconds reveals the timeliness of this report -- this ticker is so new that the company's information hasn't yet been added to our database! The information listed there is incorrect, and the Fool regrets the error.
