Understanding Schedule 13D and 13G Filings
Schedule 13D and 13G filings are SEC disclosures required when an investor acquires more than 5% of a company's outstanding shares.
Schedule 13D (Activist)
Filed when an investor may seek to influence management, board composition, or corporate strategy. Requires disclosure of investment purpose and plans.
Schedule 13G (Passive)
Filed by passive investors (mutual funds, index funds, institutions) with no intent to influence. Simpler filing requirements.
Gap column: Days since previous filing for the same fund+company pair.
Data source: SEC EDGAR. Filings typically available within 4 hours of submission.
This page reflects disclosed ownership changes only. Absence of activity does not imply absence of interest.
