We will see over time, but as of the moment seems to me like the news media/hedge funds scared all the mom and pops outta GILD yesterday and bought right into it. Ever since the lows yesterday its been a steady climb up.
You can't judge based on stock price action in one or two days. You'll see over time. CV therapeutics purchase was thought to be good until GILD's drug in similar space failed. If GILD were really determined to be a leader in HCV, they shouldn't have bought the previous two in oncology and inflammation space.
