InsiderHoward T Slayen
This page shows the track record and history of SLAYEN HOWARD T insider trades in Aehr Test Systems, Inc.. The SEC defines Insiders as officers, directors, or significant investors (greater than 10% ownership) in a company.

However, they must report all trades to the SEC via a Form 4.
