How to read these transactions

There are 3 filed transactions for Altimmune, Inc. (ALT) between 2026-11-13 and 2026-11-13. They were made by 3 different people. Open-market buys: 3, for $82,244. Sells: 0, for $0.

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.
