  2. Insider activity
SEC Form 490-day public windowUpdated periodically

Insider activity, without the mythology.

Explore clean open-market purchases and sales reported by company insiders. Ironclad shows what was disclosed, how quickly it was filed and where purchases clustered — without turning filings into a recommendation or price prediction.

Public recency

Company totals and qualifying clusters cover the trailing 90 days.

Clean comparisons

Purchases and sales use the same non-derivative, zero-quality-flag rules.

No signals

No scores, rankings, alerts or claims about what a share price will do next.

Recent disclosures

Clustered open-market purchases

A cluster requires at least two insiders, purchases within 30 days and at least $50,000 in aggregate. The date shown is when the final constituent filing became public.
