"filed an initial insider ownership report for M. P. de A. Brandao Carlos A."

The percentage of a company’s stock held by people with access to inside information or control, typically officers, directors and large shareholders who work at or help run the business. It matters to investors because it shows how much “skin in the game” insiders have and can signal alignment of interests, potential for concentrated control, and effects on share liquidity—like neighbors owning most of a street, which changes how decisions are made and how easy it is for others to move in or out.
