Investors should note that institutions actually own more than half the company, so they can collectively wield significant power. It looks like hedge funds own 5.2% of Aehr Test Systems shares.

Insider ownership is positive when it signals leadership are thinking like the true owners of the company. However, high insider ownership can also give immense power to a small group within the company. This can be negative in some circumstances.
