If you are interested in biotechs I suggest you take a look at Provectus Pharmaceuticals - trading under the ticker PVCT on the OTC market in the US.
There are aspects of PVCT that bear comparison with Dendreon (NASDAQ:DNDN) and Prima Biomed (ASX:PRR).
Like all biotechs the SP tends to be volatile and currently has seen a significant retrace from a high in October which occurred after a presentation at an Oncology conference: http://www.biobusiness.tv/report-on-location/provectus-presentation-at-cancer-immunotherapy-conference-1578/
This retrace has occurred in a vacuum of news from the company, something common in biotechs! There has also been some dilution, of which there may be more along the way.
There were also presentations from Dendreon and Prima at that conference with videos on that site also.
I have contacted the company who have sent me analyst reports that are very bullish for this stock, and also technical information. The company is very communicative. The online biotech publications are bullish as well - check out the links to these here: http://www.google.com/finance?q=OTC%3APVCT
As always, this is only my opinion and represents only knowledge available in the public domain and please DYOR
