Wab,
I tend to stay out of biologics for a number of reasons but I agree that they are not "in favor" right now; well most medical and pharma. are out of favor right now too.
I can't really give you much in the way of insight other than a general trend. Most of the very good ones are private and not public, so you can't buy their stock. One thing to consider with biologics is that FDA is looking very hard at allowing "generic" versions of biologics to be sold. Currently, this is not allowed so if FDA allows it, the price of biologics will go down over time and these companies will make less. I would not look for a big jump in this area for some time and that depends on stem cell research and the FDA biologics generic ruling. Just look around at who has biologics for the major disease areas and do your research on the last few years. I would look at SRLS. They are agile and hostile in the world of biologics and are doing well in a crappy market. Other than that, just look for companies that cater a larger market than just a single disease (cancer) or product.
