From 15 valuation models · updated 23 days ago

Fair value updated Jul 17, 2026, revised from €3.36 to €6.72 (+100.0%) since Jul 14, 2026. Share price +18.3% over the past month.

Below-average quality, and screening another 63% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (€10.88). The favourable scenario is already priced in.
  • The model range is unusually wide (€2.56 to €10.88). The outcome hinges heavily on assumptions, so read the point estimate with caution.
  • Solid but not exceptional quality (47/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis

Acerinox, S.A (ACX) currently trades at €17.97, while our model-based Fair Value estimate is €6.72, implying the stock looks roughly 62.6% overvalued today. The Quality Score stands at 47/100 (below-average quality), in the Basic Materials 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, Acerinox, S.A generated revenue of €5.6B at a net margin of -0.8%. Revenue declined 10.8% year over year. It earns a return on equity of -2.6%. Net debt stands at €1.2B. Fundamentals as of Jul 17, 2026

Our scenario range runs from €2.56 (bear case) to €10.88 (bull case); at €17.97, 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 near its 52-week high and 85% above its 52-week low, currently above its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -7% fair-value upside, at -63%, ACX 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.
