The P/E Matrix — Growth × Quality × Risk
What a multiple must be paid for
A P/E is only "high" or "low" against what the business delivers: growth (how fast profits compound), quality (how reliably — moats, margins, ROIC), and risk (leverage, cyclicality, obsolescence). High growth + high quality + low risk = the market rightly pays 30×+. No growth, cyclical, levered = 6× is not a bargain, it is a warning.
The practical screen
Before calling any P/E cheap or expensive, write the implied story: "P/E 35 says this company compounds earnings ~15%+ for a decade without stumbling." Then ask what would falsify it. If you cannot state the story, you cannot judge the multiple — you are just pattern-matching numbers.
