Price
kr135.25
The price needs 14.0% growth a year for ten years. The AI thinks 1.5% is achievable, at a 45.0% margin.
The -12.5% valuation gap indicates the stock price requires an unsustainable 14.0% growth rate at 45% margins, versus the achievable 1.5%, confirming significant overvaluation and a weak investment case.
