P/E Ratio — What It Really Tells You
7/6/2026
fundamentals
guide
P/E = price divided by earnings per share: how many rupees you pay for one rupee of annual profit.
Level by level
Beginner
A P/E of 20 means 20 years of today's earnings to repay the price. Lower can mean cheap — or broken; higher can mean expensive — or fast-growing.
Intermediate
Compare within the SAME sector and against the company's own 5-year band. Banks at 8-15 and software at 25-40 are both normal.
Advanced
Earnings quality decides everything: one-off gains fake low P/Es. Cross-check with cash flow; forward P/E embeds analyst guesses — know whose number you're trusting.
Common mistakes
- Comparing a bank's P/E with a software company's
- Buying low-P/E value traps with dying earnings
