Pharma stocks/ETFs

Amidst this correction (or bearish market), what's up with Pharma stocks? I would've thought that Pharma was a good sector with decent growth in the short and medium terms (long term surely), strong dollar supports exports, etc But they've taken a beating the past 2 days. Some downward movement was expected along with the overall market but I'm surprised at the severity. Any thoughts about pharma stocks in the short/medium term going forward? Would love to hear your inputs. (Disclosure - I bought some pharmabees on Friday and they're 5% down now. Should I buy more and average... or wait for further dip?)
