Ann: DFS delivers A$1.9BN NPV confirming World Class Project, page-252

To be honest, I dont think FSB was banking on the VWAP linked performance bonus. Being brokers, they would most likely have been instrumental in this humungous tree-shake which, if you think about it, forces weaker hands to sell off, which they (FSB) accumulate, thereby creating a tighter supply - the result? Higher prices.
Another theory, is they bought and sold under tightly controlled market conditions thereby already creating a massive profit for themselves, thereby making the performance shares irrelevant.
As for the volume bit - cant account for that. I dislike higher prices on weak volumes - they do not last.

I have personally come to the conclusion that market manipulation for this share is absolutely rife and we are not going anywhere until the powers that be say we can.
