From the Form 4s insiders file with the SEC within two business days of each trade. Before May 20, 2026 the table lists open-market purchases and sales only (no grants, option exercises or tax withholding), from the SEC's quarterly data sets. The 10b5-1 mark comes from the form's own box (since April 2023) or from a footnote of the filing that names the plan, where there is one.

From the Schedule 13D and 13G filed with the SEC since Dec 18, 2024, when they became structured data. A holder who has filed nothing since then is not shown here. A 13D is updated within two business days of any material change, a 13G up to 45 days after the quarter of the change, so the shares are those of the filing. The large managers also appear in the 13Fs.

This is not the number of shares sold short today: it measures short sales within each day's trading, and only trades made off the exchanges. Much of it is market makers, who sell shares they do not have to fill buyers' orders and cover soon after, so for a heavily traded stock the share is often around half.
