In plain terms

When two or more independent bearish signals fire on the same stock within a month, it's a much stronger short than any single signal alone.

How it works

≥2 independent short-side signals (FTD persistence, Form 144 overhang, 13D conflict, FAERS severity spike, NHTSA recall, layoff event) within 30d collapse measurement-error noise and amplify joint short conviction.
