Featured · The form that powers every row

SEC Form 4

Form 4 is the public filing officers, directors, and 10% holders use to disclose changes in their company stock ownership. Every row in the Blue Collar Picks feed traces back to a Form 4. If you only read one explainer, read this one.

The transaction code, dollar value, and role tell you whether a filing is a real open-market buy, a routine grant, a tax withholding, or a scheduled sale. The full lesson walks through each.
