I wouldn't underestimate the number of true longs that flip a large percentage of their holdings. I think too many people have recognized the pattern of sell on news and take advantage. I honestly don't see anything wrong with that as flippers have to buy back at some point, and that probably is why this stock runs so easily once it gets started. I personally don't bother with flipping, but I must admit that I have been tempted... I just know I would never stop kicking myself if my position were light when some blockbuster news comes out.
