"P/E is 22x" tells you almost nothing on its own. For a cyclical energy name, 22x is nosebleed-expensive. For a compounder, 22x can be historically cheap. The only useful framing is where today's P/E sits inside this specific stock's own history — the P/E percentile.

P/E Percentile, Not P/E Number

A P/E percentile of 85% means today's P/E is higher than 85% of all daily readings over the lookback window (typically 5 years). That is an objective, stock-specific expensiveness score — it normalises away the problem that every company has a different "normal" P/E.

<20%
Historically cheap
Current P/E is in the bottom 20% of this stock's own history. Either the market has forgotten something about the story, or fundamentals have genuinely deteriorated. Worth investigating.
20-80%
Normal range
The stock is trading where it usually trades. Valuation is a non-signal — decisions should come from growth, catalysts, or other factors.
>80%
Historically stretched
Today's multiple has only been higher on ~20% of trading days in the last 5 years. Possible — but the stock needs a genuine narrative shift to justify staying here.

Why "Cheap vs Peers" Is a Worse Framing

Comparing a stock's P/E to sector peers sounds smart but breaks in two common cases:

  1. The whole sector re-rates. If every semi is trading at 30x, you cannot tell whether the group is expensive or the old 20x average was the anomaly. Percentile against the stock's own history bypasses this.
  2. Business mix drifts. A company that was 60% hardware / 40% software five years ago may be 30/70 today. Its "peer group" moved; its own history did not.
The P/E number is a raw reading. The P/E percentile is the reading with context. Always read the percentile first — and only fall back to the raw number when you need to explain the story.

Where to See P/E Percentile in the App

Every ticker's valuation snapshot on the Valuation page shows both the current P/E number and the percentile bar. The bar is coloured green / amber / red using the 20/80 thresholds above, so a single glance tells you whether valuation is a signal or a non-signal for this name.

P/E in isolation = meaningless
P/E percentile = where today sits in this stock's own history
Read the percentile first, the raw number only for context
