Only thing I can think of is that it ran up pretty good since November. Possibly expecting a larger beat, I would think maybe two or three day sell off and then a continuation of the up move because earnings were what was expected. Sell the news event, I think.
Think your right, was a pretty nice runup last couple weeks. I sold all on the brief upswing after E/R @ 36.22, bought back some this a.m., @ well under 35, so I am just gonna watch for a while . Broke my own 3day post E/R rule after beatings, but just nibbled !! Nibbled at NUAN, and RVBD this A.M., USING my 3day rule, think they both got a little Overkill !! BLTA !
