After the quarter end: fill in an old 13F with what came later
A 13F arrives months late. Each manager's page lists what it reported to the SEC after that date: stakes above 5% and its own trades.

Step by step
- Open the manager's page from the search box, the ranking or the manager directory. If you start from a well-known investor, tap the Full profile link with the firm's name on their page.
- Read the line of dates: the date of the portfolio, when it was filed with the SEC and when the data was updated. The gap tells you how old the snapshot is.
- Scroll down to What it reported after the quarter end: stakes above 5% (13D and 13G) and its own Form 4 trades filed since then, each with its document.
- If a 13D shows up, open 13D and 13G to read the stated purpose.
- To see only its large stakes, tap See its stakes above 5% on the page.
With a free account, one step further
- The Moves tab lets you pick any quarter since 2013 and flags when an opening is larger than that manager's previous ones.
- On the stock's page, the Insiders & 13D tab shows the history of each holder above 5%.
What to look for and how to read it
- A 13D filed after the 13F is the most recent information there is on that manager: it is filed within days, not months.
- “Moved from 13G to 13D” means it no longer reports itself as passive; the stated purpose, quoted as filed, says why.
Limits and caveats
- It is not everything it did: only what it must report before the next 13F. The page says so.
- Form 4 filings only appear when the manager holds a board seat or more than 10% of the company's shares.
- A 13D is not always a purchase: founders, swaps and shareholder agreements file them too. Read the document.
Everything comes from public SEC filings. A 13F is filed up to 45 days after the quarter ends: these are not real-time positions. It is for research, not investment advice. How to read a 13F.
