0. Bottom line first

There is a contradiction in valuing a company only by comparing market capitalization with the money it earns today. The key question is whether the company should maximize current profit, or reinvest the cash it earns from a monopoly position to expand the eventual growth curve.

1. The monopoly supermarket analogy

Assume a new city has 100,000 residents and only one supermarket. No other supermarket has the right to enter, and this company has the exclusive right to operate supermarkets in that city.

Interpretation: For this kind of company, I need to ask whether it is more important to make a lot of money from one store today, or to reinvest all of the earnings and expand the scale of the supermarket business.

The core task is estimating sales and operating margin once growth matures

2. First imagine the point where growth slows

Ultimately, I need to estimate what the company’s revenue and operating margin could be when its growth curve has mostly slowed, roughly when growth falls to around 10% per year or below. If the company is still in the middle of rapid growth, that mature-state imagination is necessary.

For example, I would estimate how much revenue a supermarket used by 100,000 people could generate, even if the estimate is not precise. Then I would discount that future cash flow back to the present.

Valuation questionMeaning
Current profitA company investing for growth can be undervalued if I only look at today’s earnings.
ReinvestmentWith monopoly rights, using earnings to expand scale can matter more.
MaturityEstimate revenue and operating margin once growth falls to around 10% or lower.
Present valueDiscount the mature-stage cash flow back to today.
