Fair Value Stock Signals

Fair Value Calculator is a global stock screening and valuation tool by fairvalue-calculator.com. For thousands of companies across the US, Europe and Asia it estimates an intrinsic Fair Value from company fundamentals, compares it with the live market price to show the upside or downside, and pairs that with a Quality Score (how good the business is) and an Evidence rating (how much data backs the estimate).

The goal is a fast, structured first read on whether a stock looks undervalued, fairly valued or overvalued — not a short-term price prediction, and not financial advice. Every number on a card can be opened up on the detail page to see exactly how it was built.

No. The goal is not to predict short-term prices or time the market. It gives a structured first view of whether a stock looks undervalued, fairly valued or overvalued based on the available financial data and valuation models — a starting point for deeper research over a multi-year horizon, not a forecast of next week’s price.

Think of them as two separate questions. Fair Value answers “is the current price attractive compared with the estimated intrinsic value?” — it is the entry-price signal (positive upside = trades below the estimate, may deserve research; negative upside = already above it). Quality answers “how reliable or risky does this look on a business level?” — it is the quality and value-trap filter.

A high-quality company can still be too expensive, and a deeply undervalued one can still be a value trap if quality is weak. That is why the interpretation sentence on every card combines both into one plain-language read.

Behind the single interpretation sentence sits a deliberately involved engine: every company is valued through a stack of independent intrinsic-value methods, blended into one estimate and then weighted by how much trustworthy, cross-checked evidence actually supports it. A separate quality-and-risk layer scores the fundamentals, and figures are verified against more than one source before anything becomes visible.

The specific models, factor weightings, evidence thresholds and verification rules are proprietary and intentionally not published — but every input is real reported data, and the full breakdown of each number is shown openly on the detail page.

Structured financial inputs and model-based scoring are the foundation; AI-assisted interpretation then helps summarise the relationship between valuation, quality and risk in plain language (and, in AI Quality, assesses a company’s competitive moat). AI never sets the Fair Value directly — the output always depends on the underlying data quality, assumptions and model limitations, which is exactly what the Evidence rating flags.

Each company is valued through a stack of independent intrinsic-value models rather than one formula. These include discounted-cash-flow variants (growth DCF, free-cash-flow DCF, multi-year revenue and earnings exit models), residual-income / economic-profit models, an ROIC-compounder model, growth-adjusted earnings multiples, and dividend-discount and asset-based methods where they apply.

Every model produces a bear, base and bull estimate. The models are blended into one family-balanced consensus so that no single style (for example pure DCF) can dominate, and statistical outliers are down-weighted. The result is the Base Fair Value, with the bear/bull band showing the plausible range. The exact models, weightings and assumptions are proprietary, but every input is real reported fundamental data, and the full model stack is listed on the Fair Value tab.

The Quality Score (0–100) measures the company’s business quality from non-valuation factors grouped into families: Profitability, Quality Growth (improving fundamentals), Cashflow & earnings quality, Financial Strength, Investment discipline, Low Volatility, Momentum, 52-week Momentum and Net Issuance.

Each factor is grounded in peer-reviewed academic research — for example Novy-Marx and Fama-French on profitability, Piotroski on improving fundamentals, Sloan on accruals quality, and Jegadeesh-Titman on momentum. Value factors are deliberately excluded from the Quality Score because valuation is already captured by the Fair Value model stack; including it would double-count. On any stock’s Quality tab you can see every individual factor, its score and the studies behind it.

The Base Fair Value from the model stack is multiplied by a Quality factor to give the Final Fair Value shown on the card. A clearly above-average company earns a modest premium and a weak one a discount, but the adjustment is capped (roughly +30% / −40%) so quality refines — never dominates — the valuation.

Governance or accounting red flags apply a separate downside penalty and can only lower the Fair Value, never raise it. The full “Base Fair Value × Quality factor = Final Fair Value” breakdown is shown transparently on each stock’s Quality tab.

AI Quality is an AI-assisted, qualitative read of a company’s durable competitive advantage (its “moat”) across dimensions such as pricing power, innovation, organisation and governance. It produces a 0–100 score that nudges the overall Quality Score up or down — above-average lifts it, below-average lowers it, weighted by how confident the analysis is.

It is an overlay on the quantitative quality factors and never sets the Fair Value directly. Each assessment is timestamped and shown with its confidence level and a per-dimension breakdown, so you can see what drove it.

Evidence is a data-density rating — how much trustworthy data actually backs an estimate — not a view on the company’s quality. It reflects how many independent valuation models could be applied, how many factors had data, the length and completeness of the financial history, and whether figures were cross-checked across more than one source.

“High evidence” means the estimate rests on rich, cross-verified data; “limited evidence” means thinner data, so the number deserves extra caution. Evidence and Quality are separate axes: a great company can have limited evidence, and an average company can have high evidence.

Upside is the Final Fair Value compared with the current market price. A positive upside means the stock trades below the model-based estimate (potentially undervalued); a negative upside means it trades above the estimate (potentially overvalued). It is a starting point for research, not a forecast of future returns.

Quality and price are different questions. A great company can be a poor entry at today’s price if the market already prices in very high expectations (negative upside). Conversely, a deeply discounted stock can be a value trap if its quality is weak. Fair Value Calculator keeps the two separate — Fair Value judges the price, Quality judges the business — and the interpretation sentence on each card combines them.

It combines Fair Value upside and Quality into one plain-language summary — for example a strong value candidate (undervalued + high quality), a quality watchlist idea (high quality but near or above Fair Value), a speculative deep-value opportunity (undervalued + low quality / value-trap risk), or an overvalued quality company. It’s a research signpost, not a recommendation.

Real, publicly reported financial and market data: official regulatory filings (company reports and XBRL), premium third-party market-data providers for international fundamentals and end-of-day prices, and industry-standard services for security and entity identification. We don't disclose the specific vendors, but every input is real reported data — never estimated. Coverage, evidence level and history depth differ by company, exchange and region.

End-of-day prices are refreshed daily for every covered exchange. Scores and Fair Values are recomputed on a rolling basis and re-run when new annual or quarterly filings arrive, with a nightly repair that re-checks stale fundamentals. Price history is progressively deepened toward about 11 years per stock, so the long-range charts fill in over time.

The Fair Value line on the chart only steps when a new annual report becomes available — it does not move with daily price noise, which is why price and Fair Value can drift apart between reports.

Every company is valued in its own reporting currency, and market caps are converted to a common currency with real, regularly-refreshed FX rates before being bucketed by size. The system also normalises exchange-specific quirks — for example London prices quoted in pence (GBX) are converted to pounds (GBP) so they match GBP financial statements, and multi-class share structures are summed so per-share figures aren’t distorted. Plausibility checks catch unit and scale mistakes before anything is published.

Every estimate is built from real, publicly reported financial data, and the full breakdown of each Fair Value and Quality Score is shown openly on the detail page, so you can always see what a number rests on. Clearly implausible data is kept out of the default view (those stocks remain findable via search). The exact models and methods are proprietary.

These are model-based estimates, not certainties. Their reliability depends on data quality, history length and the assumptions behind valuation models — which is exactly what the Evidence rating signals. Always treat the output as a research starting point, not a precise truth.

Some companies have short histories, missing financial fields, fewer applicable models, or data that fails plausibility checks. Those either carry a lower Evidence rating (treat with caution) or, if the data is implausible, are withheld from the default browse to avoid showing misleading numbers — though you can still find them via search. As more or better data arrives, their Evidence and visibility improve automatically.

Yes. You can filter the global universe by region, country, market-cap size, industry and multiple sectors at once, and narrow by Evidence tier. Sorting by Fair Value ranks stocks by estimated upside (finding possible undervaluation); sorting by Quality ranks by business quality and factor strength (finding higher-quality candidates). Search finds any stock by name or ticker, including ones withheld from the default browse.

A saved Watchlist (Pro) tracks your stocks with Hold/Sell signal logic and a diversification view across sector, country, size and correlation. The optional Values & ESG layer lets you flag or softly exclude sectors you’d rather avoid (ESG = Environmental, Social & Governance — how a company treats the planet, people and how it’s run). It is a personal preference layer, never a moral judgment, and only shown where data exists.
