i heard the same rumour also. i also have been watching it closely and the way it looks now there has been no margin sellers for some time now. Looks like those that were in margin are gone now.
But still some manipulators of the stock around. They have been soaking it up since Jan.& now seemed to of stopped.
I have put in a complaint a few weeks ago to the A.S.I.C. & A.S.X. to make them aware of it
