13D and 13G: stakes above 5% disclosed to the SEC
Stakes above 5% are disclosed to the SEC within days, not months like the 13F. A disclosed stake is not always a purchase: a 13D is filed by anyone who may influence the company, which includes activists, but also founders, executives with a large stake, shareholder agreements, debt-for-equity swaps, sellers paid in stock or SPAC sponsors. A 13G, by passive investors. 13F vs 13D vs 13G: how they differ →
- What is included: initial filings from the last 30 days. Amendments (13D/A and 13G/A), where increases, decreases, changes of purpose and changes of filing entity show up, are kept apart: the largest changes further down this page when the data is there, and all of them on each stock page, under “Above 5%”.
- 13G filings are listed only when the filer is a concentrated manager; 13D filings, from any filer.
- The date on each row is the filing date. The event that triggers the filing is earlier (up to 5 business days for a 13D; longer for a 13G) and is stated in the linked document; when the data carries it, it is shown alongside.
Initial 13D filings (60)
Not all of them are activists: the “Concentrated manager” label marks those that also file a 13F and count in that group. In quotes, the start of the stated purpose, when it says something; the full text is in the SEC document.
Order: well-known investors and concentrated managers first; then the rest.
