Where insider ownership starts.

Form 3 is an initial ownership statement filed when someone becomes a reporting insider. These holdings do not mean they bought shares that day.

Sources, coverage & how to read this data

Figures are as reported to the SEC and merged with later amendments where Akkru could match them. Preview limits apply to what is listed, not to the totals, which come from the complete reported data. Nothing is zero-filled: a missing quarter or month is shown as missing.
