From our 10-year history, classified with the same rules as current flags. Older flags have no page of their own; see the research study for how flagged stocks did afterwards.
Computed only from the verified red flags below: each flag earns points for its severity, loses half its weight every 180 days, and companies with several different flag types in the past year get a bonus. Total points 0.4 → score = 100 × (1 − e−points/50) = 1. Full method

The red flag score summarizes how many, how serious and how recent a company's verified SEC red-flag filings are. It describes filing events only. It is not a fraud score, credit rating or prediction, and not investment advice.
