# Methodology

Compare historical weekly prices with annual reported fundamentals. All features are free.

## Annual reported facts

Basic and diluted EPS come from supported SEC Company Facts tags in 10-K and 10-K/A filings; EPS is not synthesized. The importer checks annual durations, selects matching periods, deduplicates restated observations, and applies later standard-taxonomy stock-split facts to per-share values and diluted shares. Filing accession, tag, unit, and filing date are retained when available. Coverage varies by issuer and taxonomy.

## Free cash flow per share

Simple FCF is operating cash flow minus cash capital expenditure. FCF/share divides this by annual diluted weighted-average shares when matching facts are available. It is a derived measure, not a standardized GAAP figure. Banks, REITs, and other businesses may have unavailable or economically unsuitable FCF measures.

## Growth and the orange reference line

CAGR uses the first and last positive annual observations within the selected chart window. Elapsed years use exact fiscal-end dates divided by 365.2425 days.

CAGR = (last value ÷ first value)^(1 / years) − 1.

Reference multiple = min(60, 15 × ((1 + CAGR) ÷ 1.10)^(years × 0.6)), with CAGR expressed as a decimal. Multiply each positive per-share metric by this multiple. For FCF/share, the multiple is applied to FCF rather than earnings. A custom positive multiple is also capped at 60.

Missing or non-positive observations create gaps in the reference line. The orange line is a formula reference, not an intrinsic-value estimate or price target. It uses retrospective information and is not a point-in-time investment backtest.

## Prices, ranges, and dividends

Weekly data retains the last available row in each week. Prefer validated split-only closes when supplied; otherwise the chart uses labeled Stooq adjusted closes as an approximation. The chart ends at the latest available price date. Company tables retain newer annual filings independently.

[Fiscal-year dividend yield](https://stockvaluelens.com/guides/fiscal-year-dividend-yield/) uses an annual reported dividend and a historical year-end close. It is off by default on the chart.
