Past experience with this stock has taught me to expect this type of decline prior to good news.
It seems to be Goldman's way of broadcasting their control. I've added to my trading position this morning.
from nasdaqdotcom, Goldman reduced 15.68% (801,547 sgares) on last 12/31/2012 report. I wonder....
Sentiment: Strong Buy
Have you noticed that Goldman reduced their holding on EXEL from most recent report?
Likewise I added more and am holding....love to add on these dips
