SEC Filings
2 updates · Last updated Apr 2026
SEC EDGAR holds some of the most useful data available to investors, but it is difficult to search and slow to read. StonkHub parses the filings that reveal who is buying, who is selling, and who is building a large position, and presents them in sortable tables.
Form 4: insider transactions
Officers, directors, and 10% owners must report trades in their own company's stock. Form 4 data shows who traded, whether it was a buy or a sale, the price, and the size. Insider screens highlight notable clusters, such as several executives buying in the same window.
13F: institutional holdings
Large investment managers report their holdings each quarter. Open any 13F filing to see the full list of positions, which is useful for following funds you respect or seeing who owns a stock you are researching.
13G and 13D: large ownership stakes
Anyone who acquires more than 5% of a company must file. A 13G is filed by passive holders. A 13D is filed when the holder may try to influence the company, which is the classic activist investor signal and can precede board fights, buyouts, or strategy changes.

FAQ
What is the difference between a 13D and a 13G?
Both are filed after crossing 5% ownership. A 13G is for passive investors; a 13D signals the holder may seek to influence the company.
How often are filings updated?
Form 4 data refreshes hourly during the business day, and 13F, 13G, and 13D filings are checked multiple times per day.
