What it checks
When a firm has both an active shelf and recent private-placement activity, ongoing share issuance creates persistent overhead resistance.
Mechanism
Rolling 90d/180d count of (shelf takedowns + Form D filings) >= 2/3. Triggers persistent SHORT 60-180d.
No production champion data for this family yet. Stats appear once the discovery pipeline promotes at least one strategy with this family tag, or once a multi-family blend that includes it earns a champion slot.
Signal rule
short focal when combined cluster >= thresh in trailing window; hold 60/120/180d.
