Applied case: Iberdrola

Macro case on Iberdrola: evaluate whether current rates and inflation regime help or hurt its operating model.

Price alone is insufficient; check margin sensitivity, refinancing pressure, and demand resilience.

This keeps valuation expectations aligned with the actual cycle.

Practical macro sensitivity example

  • If Iberdrola earns €0.78 EPS and market pays 25x in low-rate regime, implied value is €19.50.
  • At 18x multiple in tighter-rate regime, implied value becomes €14.04.
  • Valuation change from multiple compression alone: -28.00%.
  • This is why macro regime shifts can move prices even when near-term earnings barely change.
