What matters now
- The large discount to fair value meets weak quality (33/100). That raises the risk this is a value trap rather than a bargain.
- The price is below even our cautious bear case (€99.21). The market is more pessimistic than our downside scenario.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (€99.21 to €191.13) leaves room in how you read the outcome.

How to read this chart
60‑month range €31.84 – €126.22 · fair‑value band €99.21 – €191.13 · the €79.45 price screens below the €145.17 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 27, 2026.
Analysis
Siltronic AG (WAF) currently trades at €79.45, while our model-based Fair Value estimate is €145.17, implying the stock looks roughly 82.7% undervalued today. The Quality Score stands at 33/100 (below-average quality), in the Technology sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: low), always confirm before acting.
Over the trailing twelve months, Siltronic AG generated revenue of €1.3B at a net margin of -5.1%. Revenue grew 3.1% year over year. It earns a return on equity of -3.7%. Net debt stands at €1.2B. Fundamentals as of Aug 27, 2026
Our scenario range runs from €99.21 (bear case) to €191.13 (bull case); at €79.45, the current price sits below 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 27% below its 52-week high and 151% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -59% fair-value upside, at 83%, WAF screens cheaper 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 4 models by family
Widest divergence: Multiples (€153.27) versus Dividend Discount (€1.91). Highest evidence: Gordon GGM (70).

Quality Score breakdown
Of which business quality 33 · Market factors (momentum, volatility) 55
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.

How we calculate Fair Value

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
