Analysis
Planoptik AG (P4O) currently trades at €8.62, while our model-based Fair Value estimate is €0.8700, implying the stock looks roughly 89.9% overvalued today. The Quality Score stands at 35/100 (below-average 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: medium).
Over the trailing twelve months, Planoptik AG generated revenue of €11.5M at a net margin of -0.5%. Revenue declined 7.3% year over year. It earns a return on equity of -0.5%. The stock trades on a trailing P/E of 130.9. Fundamentals as of Jul 20, 2026
Our scenario range runs from €0.6200 (bear case) to €1.11 (bull case); at €8.62, 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 share trades about 46% below its 52-week high and 169% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -45% fair-value upside, at -90%, P4O 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 8 models by family
