$Ciena(CIEN.US) Bears might say, this is trading at 60 times Forward P/E, 300+ P/E, 15 times P/S, Many analyst targets are around $150 blah blah. I agree with them. I think an epic short is brewing in some of these names but we can't front-run these ideas before technicals breakdown. $Lumentum(LITE.US), $Applied Optoelectronics(AAOI.US), $Coherent Corp.(COHR.US), etc are almost in the similar zone.
