How to read these transactions
There are 17 filed transactions for AMERICAN TOWER CORP /MA/ (AMT) between 2023-04-28 and 2026-10-29. They were made by 2 different people. Open-market buys: 15, for $63,718. Sells: 2, for $290,823.
Each transaction comes from a Form 4, the filing the person submits to the SEC. In the table, each row is one transaction: the date, who made it and their role, whether it is a buy or a sell, the number of shares, the declared price per share and the total amount.
Open-market buys are the ones people watch most, because whoever makes them puts in their own money. Sells say less: they often respond to taxes, diversification or sale plans scheduled in advance. A single transaction does not say much either; what people look at is whether they repeat, from how many people and for what amount.
