It appears the bull run from the beginning of 2012 is coming to an end and profit taking is now taking place in Gilead, leading to a correction in its price. Similar set ups/ topping formations can be seen in other Bio-tech stocks and Gilead has one of the biggest pullbacks out of all of them. This can give a nice entry for a short position.
