Value is a range, not a point
A valuation model converts assumptions about growth, margins, reinvestment and risk into an estimate. Because each input is uncertain, a single fair-value number can imply more confidence than the evidence supports.
Use a base case and at least two boundary cases. The spread between them is information: a wide range means the thesis depends heavily on uncertain assumptions.
Reverse the market price
Instead of asking only what the business is worth, ask what growth and profitability the current price requires. If those expectations look demanding relative to the company’s history and competitive position, the margin of safety may be thin.
- Identify the earnings or cash-flow level implied by the price.
- Compare the implied growth period with industry economics.
- Stress the reinvestment needed to support that growth.
