Would it be an idea for GXY to do a bit of a share buy back?
If the company basically invested some of its cash into itself and suddenly wiped out 10 or 20 million shares at these basement bargain prices wouldn't that be a good positive sign to show the market?
And it could absolutely destroy some of these shorts which would affectively release the handbreak that is so firmly on?

As the SP goes up and shorts start to cover that will cause it to go up further which will burn more shorts and so on in a snowballing kinda way..

Is any of this true? Or even legal? Or have I spent too much time in Amsterdam lately?
