How to read these transactions
There are 68 filed transactions for Cerebras Systems Inc. (CBRS) between 2026-09-04 and 2026-10-27. They were made by 6 different people. Open-market buys: 0, for $0. Sells: 68, for $149,336,832.
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.
