How the rule judges a company

Is COST undervalued? Six plain tests

The rule asks what Buffett-style investors ask, using only Costco’s own SEC filings: is it worth more than its price (upside of 20% or more to model value), is it a good business (a quality score of 0.5 or more), does it really make money (profits and positive cash earnings), and can it carry its debt (net debt under 3.5× operating income)?

It also skips cyclicals at peak margins, where today’s profits flatter the price. Read the method in plain English, exactly how each number is calculated, or why a margin of safety matters.
