Frequently Asked Questions

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

SignalX aggregates every TSM 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 TSM file with the SEC?

Taiwan Semiconductor Mfg (TSM) 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 TSM 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 Taiwan Semiconductor Mfg (TSM).

What is TSM's SEC CIK number?
