Frequently Asked Questions

Where can I find MRX insider trading activity (Form 4)?

SignalX aggregates every MRX Form 4 insider transaction from SEC EDGAR. Form 4 reports show when officers, directors, and 10% shareholders buy or sell company stock, with transaction code, share count, and price per share.

How often does MRX file with the SEC?

Marex Group plc (MRX) files a 10-K annual report once per year (typically within 60 days of fiscal year-end) and 10-Q quarterly reports three times per year. 8-K current reports are filed as needed when material events occur, and Form 4 insider transaction reports are due within two business days of a trade. SignalX monitors SEC EDGAR daily to surface every new MRX filing with AI-powered analysis.

What is the difference between 10-K, 10-Q, and 8-K SEC filings?
