Questions & answers

How much stock are company insiders buying?
Over the last 90 days, U.S. company officers and directors bought $951.9M of their own companies' stock on the open market, across 807 companies. A further $4.4B was filed by 10%-owners and institutions, largely IPO and financing positions rather than open-market conviction buys. Dated monthly breakdowns live in the report archive on this page.
Why split "insider buying" into executives vs institutions?
Most large "insider buys" on Form 4 are filed by 10%-owners such as venture and private-equity funds, often for IPO or private-placement shares rather than open-market purchases. Tracefour separates individual officer and director buying (the conviction signal people mean by "insider buying") from that institutional flow so the headline number isn't misleading.
Which sectors are executives buying the most?
Over the last 90 days, the most executive buying by dollar value was in Finance & Insurance: $184.9M, about 19% of executive purchases.
Which insiders have the best recent track record?
Among executives with two or more open-market buys of $100K+ in the last 90 days, Fabela Augie K II has the strongest record on Tracefour right now, with a median +42.4% price change since each buy (2 buys). Track records describe past filings and price history only. They are not a prediction of future performance.
What is an SEC Form 4 filing?
Form 4 is the disclosure that corporate insiders (officers, directors, and holders of 10% or more of a company’s stock) must file with the SEC within two business days of buying or selling shares. Every filing is public record.
Does a stock go up after insiders buy it?
Not reliably. Insider buying is one public data point, not a forecast. Historically some stocks rise after insider purchases and others fall. Tracefour shows what was filed and how prices have moved since. It does not predict prices or give investment advice.
