How much the market pays for each dollar of annual profit. P/E = Stock Price / EPS. The raw number means little — what matters is whether it's high or low relative to the company's own history.
Price / Earnings Per ShareThe chart shows five color-coded historical zones: green (below 10th percentile) means historically very cheap, fading through lime and gray (the normal 25th–75th range) to orange and red (historically expensive). When the line sits in a green or lime zone, the stock is trading at an unusually low P/E relative to its own history.
- Cyclical businesses look cheapest on P/E at peak earnings — the "earnings trap." Use EV/EBITDA or normalised earnings for energy, materials, and financials.
- A falling P/E trend may signal a business in structural decline, not a buying opportunity.
