Also, I can understand the reason for selling a stock that has increased in value. Except for listed preplanned sales, it makes no sense for insiders to sell prior to an increased dividend payment. I have theory, but do not want to speculate, at this time.
Last filing shows he still has some shares but almost nothing. I suspect he probably sold out on Friday but no filing yet. Will be interesting to see if they ask him to give up his board seats now that he has little to no vested interest in the company.
