Two companies can report the same EPS and still trade at very different P/Es. The ratio differs because the market is weighing several things at once.
- Growth expectations — a company expected to grow profits quickly often carries a higher P/E.
- The sector it belongs to — different industries habitually trade on different multiples.
- The company's own history — today's P/E compared with its own past range.
- Risk and quality — debt, how stable profits are, and how predictable the business is.
| Fictional company | Share price | EPS | P/E |
|---|---|---|---|
| Nova Industries | ₹220 | ₹10 | 22 |
| ABC Manufacturing | ₹120 | ₹10 | 12 |
Same EPS, different P/E — the difference raises questions, not answers.
Looking at this table, it is tempting to call ABC 'cheap' and Nova 'expensive'. Resist that. The gap may reflect faster expected growth at Nova, the habits of the sectors they operate in, or different levels of risk and debt. The ratio is a starting point for investigation, not a conclusion.
How to investigate a P/E
- Compare it with the company's own P/E over the last 5–10 years.
- Compare it with close competitors in the same industry.
- Ask what growth the market might be assuming at this price.
- Check debt, cash flow and how stable profits have been.

Whenever you see a P/E, turn it into questions: what has this company's P/E been historically? How does it compare with peers? Is profit growing, flat or falling?
