Context and risks
The rise in 10-year yields (5.17%) and AI doubts pressure high-duration tech stocks; Ciena, with a P/E of 80 and 37% revenue growth, is sensitive to that factor. However, its demand is tied to AI capex, which remains a structural tailwind.

Verdict: Hold; momentum and growth are strong, but the valuation leaves little room for error if the AI cycle cools.
Main risk: Extreme valuation (P/E 80, EV/EBITDA 50) pricing in near-perfect growth; any disappointment in AI capex or a further rise in rates could trigger a severe correction.
