P/E Ratio Explained: What Are You Really Paying For?

The P/E ratio answers one question: how many rupees are you paying today for ₹1 of the company's annual profit? A P/E of 20 means ₹20 per rupee of earnings — hold everything constant and profits alone would take 20 years to "pay back" your price.

Why P/Es differ so wildly

A steady bank at P/E 12 and a software firm at P/E 60 can *both* be fairly priced, because a P/E is really the market's growth forecast in disguise. Fast-growing profits justify paying more per current rupee — you're buying the future stream, not this year's. That's why comparing a stock's P/E against the *market average* misleads; comparing it against its own sector informs. SelectStock's fundamental score does exactly that — valuation versus sector median, not versus everything.

When "cheap" is a trap

The most dangerous stocks often carry the lowest P/Es. A P/E of 4 usually isn't a bargain — it's the market pricing in a profit collapse: a dying industry, a one-time earnings spike (asset sale), or governance smoke. Before celebrating a low P/E, open the Financials tab and check whether the "E" is real, recurring and growing. If earnings halve, that P/E 4 silently becomes P/E 8 without the price moving.

And when high isn't crazy

A P/E of 60 with profits compounding at 35% can be saner than P/E 10 with shrinking profits. The bridge between the two is the PEG ratio — P/E divided by growth — where roughly 1 suggests you're paying fairly for the growth you're getting (we compute it for you).

Use P/E as a *question*, never an answer: "what growth is priced in — and do the financials support it?"
