Ive noticed in the last two 2 days on open there has been some decent buy orders for EMP at 9c there was a buy order for half a million yesterday on open and it was swamped with people taking them out.
Then again today this time a million to buy at 9 and so far no takers, a bit strange considering it closed at 8.5c yesterday.
I wouldnt mind knowing which broker has had those orders in the last few days, they may be privvy to some information about EMP restructure or it may just be yet another false dawn, anyone else been watching these bids for EMP
