That is a question only you can answer. What the stock does stocks today or tomorrow only matters if that is your time frame. I just bought yesterday, but as I stated this is a buy and hold for me. I also took a very small position figuring 50% likely hood Arry would drop to 5.50-5.64, which it did. Arry is a spec play only, and their technologies have yet to go to market. That said, their partners are some of the best in the world and have been spending MILLIONS to develop arry patents. In spite of Arry's management, internal short falls, etc., I figure Novartis and others electing to commence Phase 3 studies needs to be the focus here. If one or two drugs exit phase 3 in a couple years Arry will trade in the low double digits minimum. Short term, could retest mid 4's, but not counting on it. So do what U think best.
