The price of a stock and the value of a stock are not the same thing. Price is what the market is currently willing to pay. Value — fair value — is what the business is intrinsically worth based on its ability to generate cash for shareholders over time.
Finding that gap between price and value is what fundamental analysis is about. This article walks through the three core methods professional analysts use to estimate fair value, how to combine them into a composite, and how to apply them to any US stock — including a worked example using a real company.
Fair value is the estimated intrinsic worth of a stock, calculated from the present value of its expected future cash flows or earnings — independent of what the market is currently pricing it at.
A stock trading significantly below its fair value is considered undervalued — the market is pricing in excessive pessimism. A stock trading above fair value is overvalued — the market has priced in an optimistic scenario that may not materialize. The challenge is that fair value is always an estimate: it depends on assumptions about future growth, risk, and the appropriate discount rate.
No single formula produces the definitive fair value. Instead, analysts use multiple methods, compare their outputs, and form a conviction range — often displayed as a "football field" bar chart showing where different approaches agree.
Best for: Companies with predictable, positive free cash flow. Mature businesses, large-caps, stable growth companies.
Not ideal for: Early-stage companies with no FCF, financials (banks, insurers) where FCF is ill-defined, or highly cyclical businesses where 5-year projections are speculative.
DCF analysis values a business by projecting its future free cash flows and discounting them back to today using WACC — the Weighted Average Cost of Capital — as the discount rate.
Terminal Value (Gordon Growth Model) = FCFₙ × (1 + g) / (WACC − g)
Where g = long-term perpetual growth rate (typically 2–3%)
TTM Free Cash Flow: $74B
WACC (CAPM-derived): 9.2%
Base case FCF growth rate: 12% Year 1-3, 9% Year 4-5
Terminal growth rate: 2.5%
Net cash (cash minus debt): +$12B
Diluted shares outstanding: 7.43B
Discounting these projected cash flows at 9.2% and adding the terminal value produces an enterprise value. Add net cash, divide by shares outstanding — and you get the DCF fair value per share.
A full 3-scenario DCF produces a range: bear case (lower growth, higher WACC), base case (consensus), and bull case (upside catalyst materializes). This range is more honest than a single estimate.
Best for: Cross-sector comparisons, capital-structure neutral analysis, M&A situations. Useful for any company with positive EBITDA.
Not ideal for: High-growth companies where EBITDA is small relative to future potential, or companies with very different capital expenditure profiles.
EV/EBITDA (Enterprise Value to Earnings Before Interest, Taxes, Depreciation, and Amortization) is a relative valuation multiple. It answers the question: how much is the market paying for each dollar of operating earnings, and how does that compare to peers?
Enterprise Value = Market Cap + Total Debt − Cash
EV/EBITDA = Enterprise Value / EBITDA (trailing twelve months)
| Metric | Below peers | In line with peers | Above peers |
|---|---|---|---|
| EV/EBITDA vs sector median | Potentially undervalued | Fairly valued on multiples | Potentially overvalued |
| Interpretation | Market may be discounting future earnings excessively | Market pricing in consensus | Premium priced in — requires growth justification |
The key limitation of multiples: they tell you whether a stock is cheap or expensive relative to peers — not whether the sector itself is over or undervalued. In a bull market, everything looks expensive on multiples. In a sell-off, everything looks cheap. Multiples are most useful as a sanity check on a DCF, not as a standalone method.

Not ideal for: High-growth companies where the P/E range is fundamentally expanding, or companies with highly volatile earnings.
P/E reversion assumes that a stock's price-to-earnings ratio will revert toward its own long-run historical average. If a company has consistently traded at a 20–25x P/E over the past decade and is currently at 15x, the market may be pricing in excessive pessimism — creating an opportunity for mean reversion.
Where Forward EPS is the next twelve months earnings per share estimate,
and Historical Average P/E is typically the 5 or 10-year mean, excluding periods of negative earnings.
P/E reversion is most reliable when the underlying business has not fundamentally changed. A consumer staples company like Coca-Cola, which has a stable competitive position and predictable earnings, tends to oscillate around a consistent P/E band. Mean reversion is a credible assumption.
P/E reversion is less reliable for technology companies, where the entire sector's P/E range is shifting as growth profiles evolve. A company trading at 40x in 2018 and 20x today may be experiencing permanent derating — not a reversion opportunity.
No single valuation method is definitive. The professional practice is to weight multiple methods and look for convergence. Here is how to build a composite fair value:
| Method | Bear | Base | Bull | Suggested Weight |
|---|---|---|---|---|
| DCF analysis | $XXX | $XXX | $XXX | 50% |
| EV/EBITDA multiples | $XXX | $XXX | $XXX | 30% |
| P/E reversion | $XXX | $XXX | $XXX | 20% |
Composite fair value = weighted average across all three methods and scenarios. This is how investment banks present valuations in pitch books and fairness opinions. Intrinsik automates this process and presents the result as an interactive football field chart.
| Company type | Primary method | Supporting method | Why |
|---|---|---|---|
| Large-cap tech (AAPL, MSFT) | DCF | EV/EBITDA | Strong FCF, complex capital structure |
| Consumer staples (KO, PG) | P/E reversion | DCF | Stable earnings, predictable P/E range |
| High-growth SaaS | EV/Revenue multiples | DCF (long horizon) | No current earnings; compare on revenue |
| Industrials / cyclicals | EV/EBITDA | P/E reversion | Earnings volatile; multiples more stable |
| Banks & insurers | P/B ratio | P/E reversion | FCF ill-defined; book value more relevant |

What is the fair value of a stock?
Fair value is the estimated intrinsic worth of a stock based on its expected future cash flows or earnings — independent of market price. A stock trading below fair value is considered undervalued; above fair value is overvalued. Fair value is an estimate that depends on growth, risk, and discount rate assumptions.
What is the best method to find fair value of a stock?
No single method is universally best. DCF is the most theoretically rigorous. EV/EBITDA provides a quick market-relative check. P/E reversion is useful for mature businesses. Professional analysts use all three and combine them into a weighted composite — a "football field" valuation range.
What is EV/EBITDA and how is it used in valuation?
EV/EBITDA compares a company's enterprise value to its operating earnings, then benchmarks that ratio against sector peers. If a company trades at 12x and peers trade at 15x, the company may be undervalued on a relative basis. EV/EBITDA is capital-structure neutral, making it useful for comparing companies with different debt levels.
What is P/E reversion in stock valuation?
P/E reversion assumes a stock's price-to-earnings multiple will revert toward its own historical average over time. If a company historically trades at 22x P/E but currently trades at 16x, reversion implies upside. Most reliable for stable, mature businesses with consistent earnings.
How do I find a stock's fair value for free?
Intrinsik offers a free stock valuation tool that builds a DCF model, calculates EV/EBITDA multiples, and applies P/E reversion — automatically from SEC filing data — for any US stock in under 60 seconds. Two free analyses per month, no credit card required.
What is a football field chart in stock valuation?
A football field chart is a horizontal bar chart showing the fair value range from each valuation method side by side — DCF bear/base/bull, EV/EBITDA range, P/E reversion range. The overlap zone across methods represents the highest-conviction fair value estimate. It is the standard valuation format used by investment banks.
Intrinsik runs all three valuation methods automatically — DCF, EV/EBITDA, and P/E reversion — and combines them into a football field composite. Built from SEC filing data. Free to start.
