this explains a bit

Maybe we have all been looking to place blame for the sharp fall in the wrong place.
Perhaps it is shareholder margin problems not company issues driving the big drop.

Released to ASX last night ... Change in shareholding notice for 452 Capital Pty Limited.
They dumped 1.547 million shares on 4 Mar 08
On a quick look - their holding as at 27 November 07
was 4.110 million shares (according to the notice)they have since purchased 27/11 - 8/2/08 825,762 shares ... probably sold a heap more since the 4th Mar, but there may be some way to go - time will tell.
