Examples

Big insider purchases have made news before. In January 2016, with bank stocks falling, JPMorgan Chase CEO Jamie Dimon bought 500,000 JPMorgan shares, about $26 million of his own money, and the purchase was widely reported as a sign of confidence.

Explain it like I'm 13

Mark E. Strome helps run HeartBeam, Inc.. Spending $600,000 of their own money on the company's stock is like a coach buying a big stack of tickets to their own team's games: it suggests they think the team will do well. It is not a promise, and insiders can be wrong.
