PE Ratio Explained — With Indian Stock Examples

The price-to-earnings (PE) ratio is the single most-quoted valuation number in the stock market. It tells you how much you pay for every ₹1 of a company's annual profit. A PE of 25 means investors pay ₹25 for ₹1 of earnings.

How the PE ratio is calculated

PE = Share Price ÷ Earnings Per Share (EPS). If a stock trades at ₹500 and earned ₹25 per share last year, its PE is 20. You can see the PE for any company on its DocStoX page — for example Reliance Industries or TCS.

What is a "good" PE ratio?

There is no universal good PE — it depends on the sector and growth. Fast-growing IT or FMCG companies often trade at PE 40–60 because investors expect earnings to rise; slow, cyclical businesses may sit at PE 8–12. The right comparison is against a company's own history and its sector peers. Browse undervalued stocks or IT sector stocks to compare PEs side by side.

The limits of the PE ratio

PE breaks down when earnings are negative, one-off, or distorted by accounting. It says nothing about debt or cash flow. Pair it with ROE and ROCE, debt-to-equity and revenue growth before drawing conclusions — which is why DocStoX shows all of them together on each stock page.
