SEC Form 4 STOCK Act Convergence

InsiderBrief scores every corporate insider trade and every congressional disclosurethrough the same 7-factor framework, refreshed nightly. We don’t republish filings — we rank them. One number, 0–100, tells you which buys and sells are worth your attention and which are noise. The rare names where both sides accumulate surface as convergence signals.

Cannabis · Foreign ordinary shares

Where US insider data goes dark — we built the missing feed.

US-listed cannabis MSOs trade as foreign ordinary shares on the OTC and file insider transactions to Canadian SEDI — invisible to most US insider trackers. We surface weekly prices, momentum, and every FMP-covered cannabis Form 4-equivalent, labeled honestly.
