Where did I say that? I asked you to do a little work on your own and not just take BOAs word for anything. I can find you any target price for any ticker looking at different analysts.
What I said was, based on what? So the company is worth tens of billions less today than it was yesterday.... Because of what exactly? Do the math. Losing 5% of hep market share while projecting to retain over 50% doesn't equate to a near 40% decrease in pps / TP or market cap. Did their treatment kill someone? Nope. Pipeline blow up? Nope. PE ratio fall apart? Nope... Was cheap at 100 and is really cheap at 90. I would need a far better reason than "BOA said so"
Trying to make a rational assessment like price target off of an irrational trading period like the last two days is itself irrational.
To answer you question: yes, I would be buying pretty much ANY company with good fundamentals and outlook like GILD once the bottom is confirmed. Especially when it's price gets hammered for a reason that is completely out of line with reduction in PPS.
