How to read these transactions
There are 90 filed transactions for Kodiak Sciences Inc. (KOD) between 2026-09-28 and 2026-10-21. They were made by 2 different people. Open-market buys: 82, for $156,986,394. Sells: 8, for $2,700,322.
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.
