How to read it
- Form 4
- The form a company insider (officer, director or owner of more than 10%) must file with the SEC within two business days of buying or selling the company's shares.
- 13F
- A quarterly list of U.S. stocks held by an investment manager with more than $100 million, filed within 45 days after each quarter ends.
- STOCK Act
- A 2012 law that requires members of Congress to report stock trades by themselves, a spouse or a dependent child within 45 days.
A real example
In January 2016, when bank stocks were falling, JPMorgan Chase CEO Jamie Dimon bought 500,000 JPMorgan shares with his own money, worth about $26 million. His Form 4 made the purchase public within days, and investors read it as a strong sign of confidence.

Who is Elon Musk?
Musk co-founded the online payments company X.com, which merged into PayPal, and used his share of PayPal’s 2002 sale to eBay to start SpaceX and back Tesla, where he became CEO in 2008. He bought Twitter in 2022 and renamed it X, and he also founded xAI, Neuralink and The Boring Company. Because he is a Tesla director and officer, every change in his Tesla shares and options must be reported to the SEC on Form 4.
Stock they own
| Stock | Shares | Price | Value | 52-week change |
|---|---|---|---|---|
| TSLA Tesla, Inc. | 1,123,324,786 | $372.11 | $418.0B | −$76.7B (−15.5%) |
Shares are the amounts reported as owned after their latest Form 4 for each company, directly and through trusts or other entities. Value uses the latest weekly price we hold. The 52-week change is what the same number of shares gained or lost in value; it is not their profit, because founders' cost is not disclosed and options and other holdings are not included.

"How it went": for a purchase, the change from the price paid to the price at their next sale of the same stock ("at sale") or to the latest price ("still held"). For a sale, the stock's change since; a fall means the sale came before a drop. Uses the prices in the filings and our latest weekly price.

Examples
Founders often sell stock on a schedule set months in advance (a 10b5-1 plan) to pay taxes or diversify, so a sale is not always a sign of doubt. A large open-market purchase with their own money is rarer and usually says more. In January 2016, JPMorgan Chase CEO Jamie Dimon bought 500,000 JPMorgan shares, about $26 million, and the purchase was widely read as confidence in the bank.
Explain it like I'm 13
Imagine the founder of your favorite game company owns a giant pile of its shares. Each time they sell some, give some away, or buy more, they must tell the government within two business days. This page adds up those notes so you can see how big the pile is and what they have been doing with it.
