@Dolci raised a good point on the crapper regarding Sean Hehirs share selling.
Yes he did it to fund the tax obligation that was triggered by the RSU's vesting, I get it and understand.
In saying that, if he truly believes that we are undervalued (as he has mentioned previously) and if he truly believes that he is steering the ship in the right direction and guiding Brainchip down the path of huge profits, then this was his opportunity to keep as many of the shares as possible and not run the risk of insider trading/buying. It was his opportunity to find a few hundred thousand dollars to invest in the company that he is heading up and to instil confidence in us investors that he believes in both the product and the direction of the company.
No, I don't know his personal financial situation but I have made the assumption that he is not skint and likely has a bit of money lying around in investments or cash here and there that he could have dipped into.
End rant.
