The terminal, up close.

Captured from the product on Nov 8, 2026 — each card opens the live page it was taken from.

What it's worth, and how we know.

Our own fair value for most S&P 500 companies, each with its confidence beside it — withheld where the models can't support one.

01 · ModelSeven modelsDCF, dividends, earnings power, multiples — only the few that fit the business are blended.
02 · BlendA range, not an averageEach model weighs in by its own confidence; disagreement stays visible.
03 · GateWithheld, not guessedWhere too few models fit, or the data can't support a value, no fair value is published.
04 · Check & dateCross-checked, datedKey statement lines are compared with the SEC filing, differences shown; each fair value carries its date.
