My understanding is that there are windows in which company mangement and directors can buy and sell. If they do so during these predetermined windows, there can be no hint of impropriety.
They could also do as you suggested and buy identical amounts at regular intervals.
My concern is that we've had the same BOD for years now and except for Gilder and McConnaughy (once each), NO ONE HAS BOUGHT ANY SHARES EVER! Including our beloved Chairman of the Board.
I'm not "buying" the insider trading argument. No one is suggesting they should do anything remotely illegal. Just put some "skin in the game" like I, and everyone else here, has.
That's all. Simple request.
