From 13 valuation models · updated 26 days ago

Share price +4.6% over the past month.

Below-average quality, screening 172% undervalued on our models.

What matters now

  • The large discount to fair value meets weak quality (38/100). That raises the risk this is a value trap rather than a bargain.
  • The price is below even our cautious bear case (€6.04). The market is more pessimistic than our downside scenario.
  • The model range is unusually wide (€6.04 to €17.23). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis

Telefónica, S.A (TEF) currently trades at €3.67, while our model-based Fair Value estimate is €10.00, implying the stock looks roughly 172.4% undervalued today. The Quality Score stands at 38/100 (below-average quality), in the Communication Services 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: medium), always confirm before acting.

Over the trailing twelve months, Telefónica, S.A generated revenue of €35.9B at a net margin of -9.5%. Revenue declined 12.4% year over year. It earns a return on equity of -8.9%. Net debt stands at €41.0B. Fundamentals as of Jul 15, 2026

Our scenario range runs from €6.04 (bear case) to €17.23 (bull case); at €3.67, 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 22% below its 52-week high and 13% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 32% fair-value upside, at 172%, TEF 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.
