OT - CIEN - Ok, so the 'explanation' is continued concern about the softer than expected guidance CIEN gave during the CC, which was weeks ago. One major analyst came out defending the stock, saying yes, he expects lighter than guided revs for 2019 and the first half of 2020, but thinks at  15.3X earnings, it's a buy at this price. I did dip my toes in the water here, thinking it might be a trade, on a (hopeful) bounce-back.
