Frequently asked questions

What counts as an insider cluster here?

A US company where at least 2 distinct reporting owners (by SEC owner CIK) disclosed purchase transactions in Form 4 filings (transaction code P, which covers open-market and private purchases) whose filings landed within the same 30-day window, currently Sep 11, 2026 to Oct 10, 2026. It is a filing-date window: a late Form 4 can carry an older trade. Grants, option exercises and tax withholdings are not purchases and are excluded; superseded filings are excluded.

Which company has the most insiders buying right now?

In Flock's Form 4 coverage, TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD (TSM) had 30 distinct insiders disclose purchases across 31 filing rows between Oct 8, 2026 and Oct 8, 2026, with a combined disclosed value of $121.5K across 31 filing rows. Combined value is the sum of each filing's own shares times stated price. Not investment advice.

Does this cover every US company?

No. Flock ingests Form 4 filings for the US issuers in its coverage scope, the securities mapped from institutional 13F holdings, not every SEC registrant. A cluster at a company outside that scope will not appear here; every count on this page is a claim about Flock's coverage, stated as such.

How does the email alert work?

The alert is being switched on. You confirm your email once now; once alerts are live, on the days a new cluster appears (a company that meets the 2-insider test and whose newest purchase filing landed since the last alert run, at least the last 24 hours) you get one email listing them with filing dates and links to each filing. No other mail, unsubscribe in one click. The list on this page is free without an email.
