Dollar volume of trades is pretty high compared to number of pumpers around here. I blew out on a standing offer of $20.50 off my $17.50 buy yesterday after riding it down to $15s. My feeling is that the bottom is in, although we may test it again. They have better science than Gilead and will be doing a billion in sales 3 years from now, so IMO it is a decent risk under $20. I will buy @ $17 again...if it gets down there.
