How about no buyout but WAAAY oversold and shorts are covering because they made their money and anticipating of partnership, EU approval, new studies for different cancers, the GHSU trials, etc. smart longs are getting in now while DNDN is super cheap? That's most likely the cause of the price....this is a slow ans steady gain not a spike overnight. That's what is most likely happening.
The past was much different for many reasons that everyone knows now. This time much different with new CEO increasing YOY sales, new sales staff, restructuring, EU trials started along with JNJ, MDVN and other trials.
Management trimming all the unnecessary fat leaving a lean Co. with future growth.
Don't forget about the technology cassettes/pipeline.
