Methodology
Everything on TGMCharts is computed from reported company filings and end-of-day market data — no hand-edited figures, no AI-written numbers. This page explains where the data comes from, how each metric is defined, and how often it refreshes.
Data sources & freshness
Financial statements, dividends, and analyst estimates come from established third-party market data providers; prices are end-of-day (not real-time). Every covered company is recomputed on a daily schedule after the U.S. market close, and each page is stamped with the date its data was last verified. When a figure isn't available we show an honest “—” rather than a zero or an estimate.
How key metrics are defined
- P/E ratio (trailing)
- Latest close price ÷ trailing-twelve-month GAAP diluted EPS. A forward P/E uses the consensus next-fiscal-year EPS estimate; impossible values (e.g. sub-1 multiples from one-time earnings) are shown as N/A.
- Dividend yield
- Trailing-twelve-month dividends per share ÷ the latest close price, computed at daily resolution.
- Payout ratio
- Trailing-twelve-month dividends per share ÷ trailing-twelve-month EPS. For REITs we note that GAAP earnings understate cash generation, so FFO/AFFO payout is the better lens.
- Margins (gross / operating / net)
- The corresponding profit line ÷ revenue, from the most recent reporting period.
- ROE / ROA / ROIC
- Net income (or NOPAT for ROIC) ÷ shareholder equity, total assets, or invested capital, respectively.
- CAGRs
- Compound annual growth rate over the stated window (e.g. 5-year revenue CAGR), anchored on reported fiscal-year values. Total-return CAGR includes reinvested dividends.
- Comparison “winner” mark
- On comparison pages, the green dot marks the stronger figure per row (lower valuation multiple, higher margin/return). Differences within ~2% are shown as “even,” and dual share classes of one company are not pitted against each other.
- Ranked lists
- Leaderboards rank the covered universe (not the entire market) by a single metric, with light sanity filters to keep one-time-distorted values from topping a list. Dual share classes of a company are counted once.
Editorial standards
TGMCharts pages are compiled by TGMCharts Research — an organizational byline, not a synthetic persona. We don't fabricate figures, we date what we publish, and we correct errors when we find them. Coverage currently spans large- and mid-cap U.S. equities and is expanding.
TGMCharts is a financial-data and research tool, not a broker-dealer, investment adviser, or financial planner. Nothing here is a recommendation to buy, sell, or hold any security. Figures are sourced from third-party providers and our own calculations; while we work to keep them accurate, we don't warrant completeness, and prices are not real-time. Past performance does not predict future results.
