Valuation Methods in Investment Banking
"What are the main valuation methodologies?" is asked in every single IB interview. Here's how each method works, when to use it, and the common interview traps around choosing between them.
A PRACTICAL EVIDENCE CHECK
Choose the method for the question and the evidence
A DCF depends on cash-flow and discount-rate assumptions; market methods depend on comparable observations and consistent definitions. A result is not automatically more reliable because a spreadsheet has more detail.
Write down the fact, your contribution, the assumption and the limit of the claim. Then identify the one question you still cannot answer. Use the related worked resource to practice that gap before choosing additional support.
WORK THROUGH THE DECISION
Choose a valuation method from the evidence available
Choose a valuation method from the question and the available evidence. A list of DCF, trading comparables and precedent transactions is incomplete until you explain what each method assumes and where it can mislead.
A method-selection worksheet
| Situation | Useful starting point | Limitation to surface |
|---|---|---|
| Credible operating forecast | DCF | Value is sensitive to forecast and terminal assumptions |
| Comparable listed businesses | Trading comparables | Differences in growth, margins and capital intensity matter |
| Relevant disclosed acquisitions | Precedent transactions | Deal terms, cycle and control context differ |
| Distinct business segments | Sum of the parts | Avoid double-counting shared costs or assets |
Fictional example: two companies each report EBITDA of 100. One needs 40 of maintenance capex; the other needs 10. Applying the same EBITDA multiple without investigating cash conversion may conceal a material difference. This does not prove which company deserves a higher multiple; it identifies missing analysis.
Reconcile disagreement instead of averaging it away
If your DCF is materially above trading comparables, list the drivers: margins, growth, reinvestment, discount rate and terminal assumptions. Then ask which differences are supported by evidence. Averaging two outputs is not a substitute for explaining why they disagree.
Use the terminal-value implied-multiple exercise to translate the DCF into a market-style comparison. For a loss-making target, avoid a positive-P/E shortcut and work through the negative-earnings acquisition example.
Match the purchase to the learning gap
If you only need the distinctions above, this free framework may be enough. A technical guide is more useful when you need practice selecting and explaining methods under interview follow-ups. It cannot substitute for current company research, a reliable forecast or professional valuation work.
Damodaran’s terminal-value discussion distinguishes cash-flow valuation from market-multiple assumptions. Use the DCF guide for model mechanics and the PE case sensitivity to practice translating valuation uncertainty into a decision.
Choose support only for the gap you found
Useful for: Candidates who know method names but cannot explain selection, limitations or inconsistent outputs.
Limit: A preparation guide cannot provide a defensible valuation without company-specific research.

Discounted Cash Flow (DCF)
Intrinsic ValueValues a company based on the present value of its future free cash flows. The most theoretically rigorous method.
Strengths
Limitations
Best For
Mature companies with predictable cash flows
Comparable Company Analysis
Relative Value (Minority)Values a company by comparing it to similar publicly traded companies. Reflects current market pricing and sentiment.
Strengths
Limitations
Best For
Quick valuation benchmarks, IPO pricing
Precedent Transactions
Relative Value (Control)Values a company based on what acquirers have paid for similar companies in past M&A deals. Includes control premium.
Strengths
Limitations
Best For
M&A advisory, sell-side valuations
The Valuation Football Field
In practice, analysts present all three methodologies side by side in a "football field" chart, horizontal bars showing the valuation range from each approach.
Typical Ordering (Highest to Lowest):
Note: This ordering is a general rule of thumb and varies by situation. The overlap zone is the most defensible valuation range.
Common Interview Questions
"Which method gives the highest value?"
Generally: Precedent transactions > DCF > Trading comps. Precedent includes control premium. But this varies, in hot markets, comps can exceed transactions.
"If you could only pick one method, which would you choose?"
DCF, because it's based on the company's intrinsic cash-generating ability, not market sentiment or deal-specific factors. But always cross-check with comps to verify reasonableness.
"When would you NOT use a DCF?"
Early-stage companies (no predictable cash flows), financial institutions (use DDM), and highly cyclical companies where a single forecast path is misleading.
"Why do precedent transactions include a control premium?"
Acquirers pay above market price for synergies, strategic control, and competitive bidding dynamics. A premium is transaction-specific and should not be assumed from a universal percentage range.
