Analysis
Ciena Corporation (CIEN) currently trades at $442.79, while our model-based Fair Value estimate is $24.40, implying the stock looks roughly 94.5% overvalued today. The Quality Score stands at 70/100 (solid quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, Ciena Corporation generated revenue of $5.6B at a net margin of 7.9%. Revenue grew 39.5% year over year. It earns a return on equity of 15.5%. Net debt stands at $490M. Fundamentals as of Aug 13, 2026
Our scenario range runs from $18.30 (bear case) to $30.50 (bull case); at $442.79, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat. The share trades about 31% below its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -50% fair-value upside, at -94%, CIEN screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 26 models by family
Widest divergence: Dividend Discount ($56.67) versus Earnings-Based ($8.56). Highest evidence: Growth DCF (80).
