Explain it like I'm 13

Abg Management Ltd. helps run ProMIS Neurosciences Inc.. Spending $8.5 million 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.
