CIENCiena
Is the price fair?
A demanding price: priced for +19% a year vs +13% a year delivered, at the top of its own P/E range, and rich vs its sector.
Priced for ~19% a year FCF growth. The price demands more than its three-year revenue growth of 13% a year, priced for acceleration.
Expensive vs its own history: P/E 71.7 vs a 31.5 median over 39 quarters (+127% vs median).
Sector median 29.4× across 209 covered peers. EV/EBIT counts debt as part of the price, so a cash-rich and a borrowed company can be compared on the same footing.
Unless marked, from derived, as of Aug 1, 2026.

Where this answer is blind. The growth-implied estimate assumes a fixed discount rate; capital-heavy sectors look structurally rich on it.
