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.

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.

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.
