fair trading on asx????

Once again action by a miner on ASX has its shareholders seeing red. Last week it was SBM now IGR. A fair way to dispell mistrust in such companies would be for any purchases above (in this case) say 1 mill shares bought in C/R should be disclosed. Together with any shares sold by that buying entity in the preceeding month should be disclosed. If all is fair and above board no one should mind this being put in place. But I bet it will never happen.
