Whenever any large broking house puts out a "BUY" on anything it does not mean they are buying, it is often a message to their retail clients. Volume increases and large holders can unload into that volume without destroying the price. A Buy call does not mean the insto's are buying for themselves or large corporate accounts.
Joyce and Clifford will likely survive. AJ less so as he is more vulnerable being the public face and CEO driving this plan. Big holders imho will still like the anti union all round cost lowering plans.
EDIT. I sincerely hope I am wrong.
