How to read GWW insider activity

Open-market purchase (code P): An insider spending their own money at market price. This is the only buy code that reliably carries signal — it is a decision, not compensation.
Grants and option exercises (codes A, M): Scheduled compensation. Most "insider buying" headlines are really this, which is why InsiderPulse weights it at a fraction of a real purchase.
Cluster buy: Two or more different insiders buying on the open market in the same window. One executive buying can mean anything; three is much harder to explain away.
