Methodology — the open formula

finapp scores a company on a small set of deterministic factors computed from public SEC filings. No hidden weights, no machine learning in the score, and no LLM in the decision. A name is flagged when it clears the quality-grower bar.

The factors (each recomputable from a 10-K/10-Q)

• Gross margin trend — is the slice of each revenue dollar the company keeps as gross profit growing?
• YoY revenue growth — how fast is the latest quarter growing vs. a year ago (the long-horizon factor).
• Margin level — structurally high margins are a pricing-power / quality signal.
• Growth durability — grew revenue in most of the last 8 quarters (not a commodity spike).
• Margin stability — stable margins, not a cyclical swing.

Plus, for the shortlist: segment growth acceleration (the NVDA-class signal), and a bounded, opt-in LLM read of the latest filing's language (it explains, never decides).

Discipline

• Point-in-time: only facts filed on or before the score date are used.
• Survivorship-aware universes; remaining bias is disclosed, never hidden.
• The record is timestamped and machine-readable (picklog.json/.atom) and cannot be quietly edited.
• Not investment advice. Past performance does not predict future results.
