Yea, I still hold a small amount of ACAD, took most of it off after the recent run-up. I'm going to hold on to what I still have for the next earnings cycle.
I still hold a lot of PTLA which has a couple interesting drugs up for approval. One got a CRL the first time for manufacturing issues, not efficacy, so I have high hopes they can address the problems.
My most recent addition that I've been building a large position in is BLCM. Bioinvest2k has some excellent posts over on the biotech board on this one.
Good luck with those short positions!
