About
What the site is and where its numbers come from. Updated October 12, 2026.
Follow The Filings shows the stock portfolios that well-known investment managers report to the SEC each quarter on Form 13F. Beside them the site tracks the companies most widely held in those portfolios, and some others: when they report earnings, what they file with the SEC, and what their executives and directors trade, from Form 4. The trades and holdings that members of Congress disclose have pages of their own.
Who it follows
The site follows a chosen list of 137 managers, not every firm that files a 13F. Managers lists them all, largest first, and Superinvestor portfolios picks out the well-known investors among them and the funds they run. One list also lets Quarter summary count how many of these managers bought or sold each stock in a quarter.
Operating companies that file 13Fs, such as Alphabet and Loews, are kept apart on OpCo 13F-HR.
How current it is
On business days the site checks SEC EDGAR for new 13Fs from 6am to 11pm New York time: every 20 minutes while a quarter’s 13Fs are coming in, every 10 minutes from a week before the filing deadline to the day after, and hourly the rest of the quarter. Over a weekend or a federal holiday, when EDGAR takes no filings, it checks only on the first morning.
Even the newest 13F shows the past. It is due 45 days after the quarter ends and lists what the manager held on the quarter’s last day, not what it holds today. How to read a 13F explains what else it leaves out.
Where the data comes from
Holdings, company filings and insider trades come from SEC EDGAR, as filed. A number the site cannot be sure of is left blank, not guessed. Earnings dates and analysts’ estimates come from market data providers, and reported results from each company’s own SEC filings. Congress trades and holdings come from the disclosures members file with the Clerk of the House and the Secretary of the Senate.
Built on open source
Follow The Filings is built on sec-13f-filings, the open-source code Todd Schneider wrote for 13f.info, and uses it under its MIT License. The way the site reads and stores 13Fs comes from that project. The pages and the list of managers are this site’s own.
