Jon,

CIEN is my largest position. Yesterday some minor analyst downgraded them from 'neutral' to sell. Today ISI Evercore reduced their PT from $48 to $43. I don't understand the reasons

behind the pessimism, especially given their CC recently. Of course they must be subject to supply chain issues. And from what I've read, I do believe that the 5g rollout, at least for the 

consumer, will be a slower process than hyped, spread over a number of years. But it is inevitable, and I feel comfortable with owning CIEN (If someone else knows why they're 

getting downgraded, please chime in.)  I wish I felt comfortable with some other toxic-looking things in my portfolio.
