Why Ciena Stock Tanked by Almost 9% on Tuesday

CIEN dropped 8.9% Tuesday after TD Cowen analyst Joshua Buchalter slashed his price target by $100, moving from $675 to $575 per share. Buchalter cited timing concerns around the company's growth trajectory as the primary driver for the cut.

Despite the reduced target, Buchalter maintained his buy rating on CIEN. He framed the stock's weakness as creating an attractive entry point for investors ahead of the company's fiscal Q3 earnings report scheduled for September 3.

The $100 price-target reduction represents a 14.8% haircut to Buchalter's previous outlook, though the $575 target still implies upside from Tuesday's closing levels following the decline. The timing of the downgrade—just weeks before the September 3 earnings date—suggests Buchalter expects near-term headwinds to weigh on results or guidance.
