What it checks

When insiders file large planned-sale notices, we short the issuer for the next few weeks.

Mechanism

Form 144 notices reveal planned restricted/control-share sales. Large notices can create supply overhang before actual Form 4 execution appears.

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

Aggregate Form 144 planned-sale market value >= $1m or $5m -> SHORT issuer; hold 10/20/60 trading days.
