Trading comps answer a market question, not a fundamental one: what is the market paying for similar companies right now, and what does that imply this one is worth? Where a DCF values a business on its own cash flows, comps value it by analogy: you find a peer set, see what multiple they trade at, and apply it. It's fast, it's grounded in real prices, and it's the first thing an analyst pulls together.
The logic is simple. If five companies in the same business trade at roughly 10x EBITDA, and your target does $200 of EBITDA, the market is implicitly telling you it's worth about $2,000 of enterprise value. The whole craft is in choosing a defensible peer set and the right multiple.
Step 1: Pick the set
A comp is only as good as its comparability. You want public companies that look like the target on the dimensions that drive value:
- Industry / business model: same sector, similar products and end-markets.
- Size: revenue and market cap in the same ballpark. A $50bn leader doesn't trade like a $500m challenger.
- Growth and margins: the market pays up for faster growth and fatter margins.
- Geography: where they earn the money, since that drives risk and tax.
Throwing every name in the sector into the set to make it bigger. A loose peer set produces a wide, meaningless multiple range. Five genuinely comparable companies beat fifteen loose ones, and you should be ready to defend why each name is in there, because a good interviewer will ask you to justify the set or kick one out.

Frequently asked
- What is a trading comparables analysis?
- Trading comps value a business off what the market is paying for similar public companies right now. You find a peer set, see what multiple they trade at, and apply it to your target. If five peers trade at 10x EBITDA and your target does $200 of EBITDA, the market implies about $2,000 of enterprise value. It is fast and grounded in real prices.
- How do you pick a good peer set for comps?
- Choose public companies that resemble the target on the dimensions that drive value: same industry and business model, similar size, comparable growth and margins, and similar geography. Do not throw every name in the sector in to make the set bigger. Five genuinely comparable companies beat fifteen loose ones, and you should defend why each is in there.
- Why do trading comps come in below precedent transactions?
- Trading comps use current trading prices, which reflect what minority shareholders pay for small stakes day to day, with no control changing hands. Precedent transactions embed a control premium because an acquirer buys the whole company. So comps typically sit below precedents, which price in the premium a buyer pays for control and synergies.
