Stock valuation methods, explained.

The basis matters

All financial results use complete annual SEC reporting periods in USD. This release does not calculate trailing twelve-month statements or analyst forecasts. Each source input is matched to its fiscal period, and the latest available restatement is retained. Fiscal year-ends older than 550 days are marked stale and excluded from cross-sectional ranking. A recent quarter may exist even when the annual model has not changed.

Growth comparisons require adjacent annual periods. Corporate actions can make historical financials economically incomparable even when the accounting dates line up. These signals help structure research; they do not replace reading the filings.

DCF value

Five-year equity cash-flow proxy: CFO minus capital expenditure, with zero net borrowing. Discounted at a required equity return; terminal growth must be lower. Any reviewed preferred-capital or minority-owner claim is deducted from the modeled equity value. This is a scenario, not an analyst target. Dated SEC outstanding shares are preferred; annual diluted shares are a fallback proxy only for issuers without an unresolved multiple-class structure. Minority-owner carrying-value bridges are disclosed proxies, not fair values.

Default scenario: 5% annual cash-flow growth for five years, 10% required equity return and 2.5% terminal growth. Equity value = Σ FCF₀(1+g)ᵗ/(1+r)ᵗ + FCF₅(1+gₜ)/[(r−gₜ)(1+r)⁵]. Divide by equivalent issuer shares for a per-share estimate. No debt subtraction is made because this is a levered cash-flow proxy. A separately reviewed preferred-stock claim, when present, is deducted from DCF and the sensitivity table and included in the reverse-DCF target; FCF yield deducts the reviewed preferred dividend run rate. Genuine FCFE would also account for net borrowing. Growth, terminal value and annual diluted share counts can materially distort the estimate. Capital expenditure means reported cash PP&E/productive-asset spending; capitalized intangibles and acquisition spending may be omitted and can overstate distributable cash.

Reverse DCF

Solves for the five-year annual cash-flow growth rate implied by the input market capitalization, using the same equity cash-flow proxy and terminal assumptions. Any reviewed preferred-capital or minority-owner claim is added to the common-equity target, matching the DCF bridge. Search interval: −50% to +100%. Requires positive base cash flow.

Relative valuation

Same-industry median positive P/E, excluding the company itself; falls back to the same sector with at least five distinct issuers. Upside = peer median P/E × company annual parent/common earnings proxy / input market cap − 1. Negative earnings and incompatible financial years are excluded. Parent-income fallbacks may include preferred dividends.

Historical multiples

Median of at least three annual P/E observations, using the latest market-cap observation in each calendar year and the latest annual parent/common earnings originally filed by that observation. Losses or missing owner earnings exclude the observation. Values use currently stored restated earnings, so this is not a point-in-time backtest. No historical market caps are inferred from current shares.

Free cash flow yield

Annual operating cash flow less capital expenditure, divided by issuer market capitalization. When a reviewed preferred issue applies, its annual coupon run rate is also deducted; this is a pro forma adjustment rather than historical cash paid. This equity cash-flow proxy includes interest payments and assumes zero net borrowing; it is not unlevered FCFF. Where CFO includes subsidiary minorities, FCF yield remains a consolidated ownership proxy unless a reviewed annual cash-flow allocation is available. A minority book-value claim is not an annual cash-flow deduction.

ROIC / quality

ROIC proxy = operating income × (1 − 21% normalized tax) / average of current and prior year financing capital. Capital = equity + reported long-term debt + reported short-term borrowings − cash. Missing short-term borrowing data is excluded and explicitly flagged, so this proxy can overstate full ROIC. Verified consolidated equity is preferred; parent-equity fallbacks are marked as a scope limitation.

This is a financing-capital approximation, not a fully standardized institutional ROIC measure. Debt taxonomy and restricted cash fallbacks can alter the denominator. A fixed tax rate improves comparability but ignores actual tax jurisdictions and losses. Negative or zero average invested capital is unavailable.

Value composite

Equal-weight mean of sector percentiles for positive parent/common earnings yield, free cash flow yield and positive parent book-to-market. Parent book can include preferred capital. All three are required, with at least five unique eligible issuers per component. Higher means cheaper relative to this covered sector sample. Not a buy rating.

Percentiles use midrank ties: 100 × (number below + half the number tied) / valid sample size. Different components may have different covered peer samples. Missing components are never substituted with neutral scores. Scores describe today’s covered universe and cannot be interpreted as historical returns.

12–1 price momentum

Split-adjusted value one month before the snapshot / split-adjusted value twelve months before it − 1. Month-end snapshots use month-end cutoffs; other dates preserve the calendar day. Observations must fall on or within ten days before each cutoff. Reviewed fund snapshots are indicative valuations, not exchange closing quotes. Cash dividends are excluded from split-only inputs.

Asset growth

Annual total assets / prior annual total assets − 1. Lower growth is conventionally the conservative-investment factor direction; acquisitions, disposals and business models can dominate the signal.

Net payout yield

(Cash common dividends + cash common-share repurchases − reported common-share issuance proceeds) / issuer market capitalization. Missing cash-flow components remain unavailable. This cash payout proxy does not capture all noncash share dilution or stock-based compensation.

Accrual quality

(Annual net income − operating cash flow) / average current and prior total assets. Verified consolidated income is preferred to match CFO; parent-only fallbacks are flagged as a scope limitation. Lower accruals generally indicate greater cash backing of earnings; extreme negatives can reflect timing or distress.

Fundamental momentum

Equal-weight average of year-over-year revenue growth, change in operating margin and change in operating-cash-flow margin. This transparent custom signal uses annual statements; it is not analyst earnings revisions. Margin changes are percentage-point differences.

Sector exceptions and missing information

Generic DCF, free cash flow yield, ROIC and accrual-quality models are disabled for Financials and Real Estate, with dated, issuer-specific reviews for payment networks and selected operating businesses such as data vendors, brokers and exchanges. Each stock page states the business basis and any methods still excluded pending a capital or minority-claim review. Banks, insurers and REITs require models such as excess returns, regulatory capital, FFO/AFFO or net asset value. Asset growth and cash-flow signals also need careful interpretation in these sectors. An unavailable result can mean missing inputs, a nonpositive denominator, stale data, too few peers or an unsuitable model. A dash never means zero.

Common-share payout inputs do not capture noncash dilution. Some issuers report share-class-specific earnings or shares under custom tags; the generic extraction needs review before a per-share valuation can be relied on. Multiple share classes are flagged. Reviewed equivalent issuer share counts are used where available, with their dates and calculation basis shown. Parent/common earnings and parent book equity exclude identified noncontrolling interests but can still include preferred claims; these accounting proxies need issuer-specific interpretation.
