How to Read P/E History
A stock's current P/E tells you what the market pays today. Its 7-year P/E range tells you whether that price is cheap or expensive relative to the company's own earnings history. Trading well below the 7-year average often signals a buying opportunity; trading near the 7-year high warrants scrutiny.
Two caveats: cyclical companies can look cheap at peak earnings and expensive at trough earnings — the historical range misleads when the earnings cycle has turned. One-time charges or windfalls also distort trailing EPS temporarily. Always pair historical P/E context with a look at how stock multiples work before drawing conclusions.
