PEG Ratio

Is a 'pricey' stock actually expensive?

Indian investors love the price-to-earnings (P/E) ratio — but used alone it misleads. A fast-growing company *should* trade at a high P/E. The PEG ratio fixes this by putting price in the context of growth. It divides the P/E by the company's earnings growth rate, telling you whether you're overpaying *relative to how fast the company is compounding*.

How to read it

The rough rule of thumb:

- PEG around 1 — the stock is fairly valued; price and growth are roughly in balance. - PEG below 1 — potentially undervalued; you're paying modestly for strong growth. - PEG above 1 — potentially overvalued; the P/E isn't fully justified by growth.

The power of PEG is that it can flip your intuition. A stock at a 40× P/E growing earnings at 40% a year has a PEG near 1 — and is arguably *cheaper* than a stock at 20× P/E growing only 10% (PEG of 2). The headline P/E made the first look scarier; PEG reveals the opposite.

Using it on Indian stocks

For NSE and BSE names, PEG is especially useful in high-growth sectors — consumer, financials, capital goods, new-age tech — where lofty P/Es are common and raw multiples cause sticker shock. But handle it with care:

- Growth assumptions drive everything. PEG depends on the *expected* growth rate, which is an estimate. Garbage in, garbage out. - Don't use it in isolation. Compare the P/E with the stock's own five-year average and its sector, then layer PEG on top. - Beware cyclical or one-off earnings. A temporary profit spike can flatter the growth denominator and make a stock look deceptively cheap.

The practical takeaway

PEG is the antidote to dismissing every high-P/E Indian stock as 'too expensive.' Quality growth deserves a premium — PEG helps you decide whether the premium is reasonable or excessive. Treat it as one lens among several, anchored on realistic, sustainable growth estimates rather than a single hot year.
