How to read these transactions
There are 8 filed transactions for Boundless Bio, Inc. (BOLD) between 2026-10-16 and 2026-10-27. All of them are by the same person. Open-market buys: 8, for $426,909. 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.
