Frequently Asked Questions

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

SignalX aggregates every TRI 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 TRI file with the SEC?

Thomson Reuters (TRI) 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 TRI filing with AI-powered analysis.

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

A 10-K is a comprehensive annual report with audited financials, business overview, and risk factors. A 10-Q is a shorter quarterly report with unaudited financials and management discussion. An 8-K is a current report filed when a material event occurs, such as earnings releases, executive changes, acquisitions, or other significant developments. SignalX provides AI-generated summaries for all three filing types for Thomson Reuters (TRI).

What is TRI's SEC CIK number?

Thomson Reuters (TRI)'s SEC CIK (Central Index Key) number is 1075124. The CIK is a unique identifier assigned by the SEC to every filing entity. You can use CIK 1075124 to look up all TRI filings on SEC EDGAR, or browse them here on SignalX with AI-powered analysis.
