PE ratio, or price-to-earnings ratio, shows how much investors are paying for each rupee of a company's earnings. It is calculated as market price per share divided by earnings per share.

How do Indian investors use PE ratio to compare stocks?

Indian investors usually compare a company's PE with its own history, sector peers, and expected earnings growth. A PE number is most useful when the businesses being compared operate in similar industries.

What should investors know about using PE ratio?

A low PE does not automatically mean a stock is cheap, and a high PE does not automatically mean it is overvalued. Falling earnings, one-off profits, or poor business quality can make PE misleading unless it is used with other metrics.

In short

PE ratio (Price-to-Earnings) measures how many rupees you pay for every rupee of a company's annual earnings. PE of 20 means you pay ₹20 for ₹1 of earnings. A lower PE is not automatically cheap - always compare PE to sector peers and historical range.

Formula: PE = Current share price ÷ EPS (earnings per share)
Nifty50 historical PE range: 14x (cheap) to 35x (expensive) - current Nifty PE available on NSE website
IT sector typically trades at 25-35x; FMCG at 40-60x; PSU banks at 8-12x - compare within sector only
PE trap: low PE can mean cheap, but also declining earnings or value trap - check earnings growth
