Ownership stakes (13D / 13G)
Investors who own more than 5% of a company, from activists (13D) to passive holders (13G).
About this data
- What it is
- An investor who owns more than 5% of a public company must say so. Investors who may try to influence the company, such as activists, file the longer Schedule 13D; passive holders file the shorter Schedule 13G.
- Who files it
- The investor, within days of crossing 5%, and again whenever the stake changes materially.
- How current
- We collect new filings throughout the day on SEC business days.
- Worth knowing
- 13G filings are far more common than 13D. A 13D usually means the investor intends to push for changes, so it tends to get more attention.
All of this comes from public filings.
