Fair value of any stock, from SEC filings

The line you are looking at is the whole product.

One line is what a business is worth. The other is what it costs. Everything Fairvalue Radar does is work out the first number honestly enough that the gap means something.

In development. Two tools are finished and free today — the DCF calculator and the comparison of valuation tools. The scored product below is being built. Nothing here can be bought yet.

Four methods · one number · filed data

One business. Four ways to price it.

Each face is a method. They resolve into a single fair price.

How the number is built

What fair value is, and what it is not.

Fair value is what a business is worth based on what it earns and owns, rather than what it currently trades for. It is an estimate, not a fact — change the growth rate or the discount rate and the number moves. The gap between fair value and price is your .

The four methods, and where each one fails
MethodWhat it prices Reliable whenBreaks when
DCF Future cash, discounted back to today Cash flows are steady and the business is understandable Growth and discount rate are guesses — small changes swing the answer
Multiples Next twelve months of earnings, at a multiple Earnings are stable and peers are genuinely comparable Earnings are negative, or a one-off distorts the base
PEG The price you pay per point of growth Growth is positive and reasonably steady Growth is near zero or negative — then it is broken, not cheap
NAV What the assets would fetch, minus what is owed The balance sheet holds real, saleable things The value is intangible — software, brands, people

No single method is right. Each is reconciled against the other three, and net asset value acts as the floor when the earnings case falls apart. If you want to feel how fragile one method is on its own, run one in the free DCF calculator and watch the sensitivity grid move.

What actually computes from filings

In August 2026 we ran all ten criteria against SEC EDGAR company facts for nineteen large-cap companies, to find out how much of the system filings alone can carry.

18 / 19Free cash flow computed in full, with multi-year history
12 / 19Incremental margin computed — blocked where gross profit is untagged
10 / 19Tagged remaining performance obligation under ASC 606
4 of 10Criteria filings cannot carry at all — they need estimates or IR pages

Runway, estimate revisions, guidance trajectory and the catalyst calendar are forward-looking, and forward-looking figures are never filed with the SEC. Those come from a paid estimates feed and from company IR pages. We would rather say that out loud than imply a filing can tell you something it cannot.

The gap

Orange is where the market disagreed with the method.

The chart behind this page is not decoration. The calm line is value, the restless one is price, and the shaded band between them is the only thing worth acting on — the stretch where a business was available for less than four methods said it was worth.

The method, in the open

Ten criteria, four families.

Each one has a shape. Click any card to read the rule behind it.

the business the cash the market the price

Reads — TAM, guided 3–5 year revenue CAGR

A larger runway with a credible guided rate scores higher. A guided rate with no market behind it does not.

threshold & weight — subscribers

Reads — Pricing power, switching costs, sustained ROIC as evidence

Written up per company, in words. Sustained returns and stable margins inform the judgment; they never make it alone.

threshold & weight — subscribers

Reads — Capital allocation, insider ownership, guidance credibility

Owners who allocate well, hold real stock and meet their own guidance score higher.

threshold & weight — subscribers

Reads — Incremental margin, period over period

Rising or steady incremental margin scores higher. Falling margin while revenue grows is penalised, not excused.

threshold & weight — subscribers

Reads — Operating cash flow minus capex, multi-year

A rising multi-year path beats a single strong year, every time.

threshold & weight — subscribers

Reads — NTM EPS and revenue revisions, 30 and 90 day

Upward revisions score higher. A run of them counts for more than a single move.

threshold & weight — subscribers

Reads — Remaining performance obligation, ASC 606

Contracted revenue growing faster than reported revenue scores higher. A blank is a blank, not a zero.

threshold & weight — subscribers

Reads — Quarterly guidance, four-quarter window

Consecutive raises score higher. One cut resets the count to nothing.

threshold & weight — subscribers

Reads — DCF, forward P/E × NTM EPS, PEG, P/TBV and NAV

Price below the reconciled fair price opens an entry. Above it, the name stays on the list and off the ticket.

threshold & weight — subscribers

Reads — Earnings dates, product dates, trial readouts, approvals

A catalyst with a date inside the horizon scores higher than a story with no clock on it.

Questions people actually ask

Fair value, in plain terms.

If you are new to this, start here.

What is the fair value of a stock?

Fair value is what a business is worth based on what it earns and owns, rather than what it currently trades for. It is an estimate, not a fact: change the growth rate or the discount rate and the number moves. The gap between fair value and price is your margin of safety.

How does Fairvalue Radar calculate fair value?

Four methods run on the same filed data: a discounted cash flow, forward P/E against next-twelve-month earnings, PEG, and net asset value. Each produces its own number. The four are reconciled into one fair value, with the asset-based figure acting as a floor when the earnings case is weak.

Where does the data come from?

Fundamentals come from SEC EDGAR company facts, the XBRL tags companies file directly with the regulator, which are free and public. Prices come from a paid delayed feed. Every figure on a scorecard links back to the exact filing line it was taken from, so you can check it yourself.

Is a stock priced below fair value automatically a buy?

No. A discount only opens the question. Ten further criteria decide whether it is worth taking: runway, moat, management, scalability, cash flow, estimate revisions, backlog, guidance, valuation and catalysts. A cheap price on a deteriorating business is a warning, not an opportunity.

What can I use for free?

A two-stage DCF calculator and a comparison of ten valuation tools, both finished and free with no account. When the scored product ships, one company will be worked through end to end for free, permanently.

Do I need to know finance to use it?

No. Every abbreviation on the site opens its own explanation: what it measures, why it moves a decision, and the arithmetic behind it. The product is built for people who are still learning the vocabulary, not only for people who already have it.

Can Fairvalue Radar place trades or connect to my broker?

It reads, it never trades. You will be able to connect Interactive Brokers read-only, or upload a CSV from eToro, Trading 212 or DEGIRO to score your actual holdings. The connection is scoped so that placing an order is not something the product is technically able to do.

Is Fairvalue Radar investment advice?

No. Fairvalue Radar is research software. It does not know your circumstances, it never places an order, and nothing it outputs is a recommendation to buy or sell. What you do with the output is your decision and your risk.
