411 transactions on file (0 open-market purchases and 359 open-market sales).
359 open-market sales by ALNY insiders, between Sep 9, 2025 and Jun 1, 2026. A sale made under a trading plan agreed months earlier is not the same event as one decided that week, and the filing itself says which.
Discretionary. The box was on the form and was not ticked. The sale was made at the prevailing price without a pre-arranged plan behind it.
Planned (10b5-1). The filer ticked the Form 4's 10b5-1 box: the sale ran under a trading plan adopted before the trade, so it is a schedule executing rather than a view taken this week.
Not stated. The filing does not say. Either it predates the April 2023 checkbox, or nothing has re-read it since. This tab will not guess which of the two above it was.

The assistant answers from what ALNY has actually filed: 18 annual reports filed with the SEC, 200 Form 4 filings from the last year, 13F positions from the 3 tracked investors who hold it and 6 funds that hold it. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from ALNY's filings and figures. One a day without an account; a free account has its own, and no card.

From SEC Form 4 filings, filed by officers, directors and 10%-owners within two business days of a transaction. “Indirect” holdings (a trust, an LLC, a family member) are included and not distinguished from direct ones in this table.
Past transactions say nothing about future ones, and none of this is investment advice.

Each person’s holding as they reported it after each open-market trade, over the last twelve months. It counts one class of stock and excludes grants, option exercises and shares withheld for tax, so a stake can fall here while somebody’s total holding does not. Since April 2023 a Form 4 states whether a trade ran under a pre-arranged 10b5-1 plan; an older one does not, and those dollars read “not stated” rather than being counted either way.
