Using Comps to Cross-Check a DCF
A DCF gives intrinsic value; comps give market value. Pros run both and investigate the gap rather than trusting one blindly.

A DCF and a comps analysis are answering slightly different questions. The DCF asks 'what are the fundamentals worth?' Comps ask 'what is the market paying for businesses like this right now?' In a perfect market they'd agree; in the real world they rarely do.
If your DCF says a stock is worth 40% more than where comps trade, don't celebrate - investigate. Either you've found genuine mispricing, or (more often) an assumption is too aggressive. The gap is a prompt to pressure-test your inputs.
- DCF strengths: fundamental, market-independent, flexible for scenarios.
- DCF weaknesses: assumption-sensitive, can dominate, assumes a constant capital structure.
- Comps strengths: grounded in real market prices, fast.
- Comps weaknesses: distorted by market swings, needs clean comparables.
The professional habit: build the DCF, build the comps, lay the implied valuation ranges side by side, and form a view about why they differ. That triangulation is what separates a defensible valuation from a single fragile number.
Your DCF implies a value far above where comparable companies trade. The best first response is to:
