A multiple is a comparison or it is nothing
Twenty times earnings is not high or low. It is twenty times earnings. The moment you call it expensive you have compared it with something, and the only question that matters is what.
There are three things to compare with: other companies, its own past, and the market it sits in. Each carries an assumption that can be wrong in a way that costs money. This page takes the first one, which is the one most people do badly and fastest. The company's own history is 15.03.02, and the market around it is 15.03.03.
Peers: same industry is not the same business
The larger company at fifteen times earnings is not obviously cheaper than Bharat Foods at twenty. Before that sentence means anything, four things have to match.
The same business model. One sells its own branded snacks; the other may make biscuits for supermarkets under their labels. Same shelf, different economics: one owns a brand, the other rents shelf space.
The same accounting. If one capitalises what the other treats as an expense, their profits are not the same kind of number.
The same growth and margins. A company growing 4% deserves a lower multiple than one growing 15%, and a company earning 20% on its capital deserves more than one earning 8%. Bharat Foods earns 20%.
The same debt. A leveraged company's P/E flatters it, because the earnings are what is left after interest but the price ignores the loans. Compare those two on EV/EBITDA, not P/E — which is the whole reason 15.02.05 exists.
Do that work and the fifteen often stops looking cheap. Sometimes it survives — and then you have found something worth attention.
When a share is cheaper than its peers, assume the market knows why — and go and find the reason before you disagree with it.
- A larger peer, P/E 15
- supermarket labels, no brand, 8% return on capital
- Bharat Foods, P/E 20
- own brand, 20% return on capital, almost no debt
- A smaller peer, P/E 28
- growing fast, thin margins, heavy borrowing
What a clean peer comparison can and cannot settle
Done properly, the comparison tells you one thing: whether two businesses are being priced differently for reasons that show up in the accounts. That is genuinely useful, and it is all it does.
It cannot tell you whether the whole group is expensive — every snacks company can be dear at once, and a peer table will look perfectly orderly while it happens. It cannot tell you whether the gap will close, or when, or in which direction. And it says nothing about whether the premium is deserved.
Those three limits are the next three lessons, in that order. Until then, the honest output of this page is a sentence with a reason in it: the larger company is cheaper because it earns 8% on capital and rents its shelf space — not simply the larger company is cheaper.
