Directors, executive officers and holders of more than 10% of a US company must report changes in their holdings on Form 4, usually within two business days. Each filing lists a transaction code: P for an open-market purchase, S for a sale, A for an award, M or X for option exercises, F for shares withheld to pay tax, G for gifts.
Not every Form 4 is a signal. Awards and tax withholding happen on a schedule, and many sales are made under pre-arranged 10b5-1 trading plans, marked here as "plan". Open-market purchases — insiders using their own money — are the rarest and the most watched.
