I'm not sure, but it all happened as the conference call began. I was listening with half an ear to the call, very complicated company to analyze being a conglomerate of internet sites. Conference call ended on a bad note with irritation on the part of the CEO with the analysts. I think the selloff was unwarranted skittishness. They stressed that it was a VERY good quarter. Analysts wanted to drill in on minutae and focus on negativity, thus the irritation. They also stressed that the company will continue to be a growth story.
Anyway, I'm glad I exited my position at $51.59. Will look for a good re-entry, depending also on overall market. Worried about the jobs #'s coming out on Friday.
