Sydney-Cloud,
"the investor donot want to buy up the SP on the market so it's normal for them to pay higher to get more shares at 1 time"
That statement puzzled me a bit.
If I were the investor, why on earth would I pay more for something if I could just buy it at a normal market price?
Eg: if you buy groceries, would you spend 20-30% extra at a particular shop if there are woolies and coles at your door step?
