Possibly short NOW Monday or Tuesday after 3 day ER run

Waiting for earnings run to diminish Monday/ Tuesday to see if it can pierce through overhead resistance high $560's, 200dma additional resistance at $588.99 and 50 dma at $607.24. If this level fails $423 is support on a very volatile stock with a 495 PE!!! in an environment of "value" rotation away from PE.
