Framework analysis

VerdictMeaning
BUYPositive purchase signal: the framework's buy requirements are met.
PASSThe company clears the framework's checklist or screen, but the framework does not produce a buy signal. For valuation frameworks this often means margin of safety is missing, insufficient, or unavailable; some screen-only frameworks have no intrinsic-value BUY state.
NEUTRALNeither a positive nor negative conclusion. It does not mean to hold an existing position.
FAILThe company does not clear the framework's requirements.
RankedRanked strategies do not use PASS: selected cohort is BUY, outside the cohort is FAIL, and unranked is NEUTRAL.

Current investor scores use trailing 12-month flows and the latest balance sheet where supported. Multi-year and EPS tests retain annual history; each framework shows its financial basis below. Intrinsic values use annual financials.
