i haven't owned zgen as long as you have david, but i do have shares starting in the 15s. that said i'd be lying if i told you i wasn't happy about the deal (and after averaging down my large paper loss has turned into a decent profit)
you can argue the valuation ad nauseam, but as the saying goes - never look a gift horse in the mouth
the fact BMY is due out next with combo data on DAAs, and we now have 2 prior DAA combos that have warts (INFORM and IDIX) i have to wonder if the BMY data will disappoint as well - opening the door (again) for the notion that combinations of DAAs will take longer to materialize and interferon is likely to remain SOC for longer than many think
i'm curious what other long time holders like clark and tony think of the deal, but i am happy to put my zgen profits to work elsewhere at this point
