Price vs Fair Value (5 years)

$627.00 $39.16 Fair Value $24.40 May 2021 Aug 2026

White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 20, 2026.

How to read this chart

60‑month range $39.16 – $627.00 · fair‑value band $18.30 – $30.50 · the $378.44 price screens above the $24.40 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 20, 2026.

Analysis

Ciena Corp (CIEN) currently trades at $378.44, while our model-based Fair Value estimate is $24.40, implying the stock looks roughly 93.6% 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 Corp 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 20, 2026

Our scenario range runs from $18.30 (bear case) to $30.50 (bull case); at $378.44, 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 41% below its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -54% fair-value upside, at -94%, CIEN screens richer than that median.

Fair Value models

This estimate rests on fiscal year 2025 figures, and about 10 months have passed since. In that time the company retained roughly 2.50 USD per share, which is 10.2 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.

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.

Note: the current price implies far more future growth than the conservative anchors of our models allow (base growth is deliberately capped, we do not regard such extreme rates as sustainable). Our models are not designed for expectations this high; that is why the individual models scatter extremely ($8.56 to $95.43). Read the values as a conservative anchor, not as a price target.
Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.

All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
