It was Pinetree buying.
That is very true, but no doubt all the hype and the increaing SP at the time encouraged more buying amongst us and others. It wasn't just Pinetree buying at the time.
Sadly, now we have a situation where there aren't alot of buyers and therefore any small amount of selling will effect the SP and this is where I think it can be manipulated if you so wished. Nobody has a crystal and therefore if enough people suggest the SP is going down and another PO is imminent and I don't deny it's a possibility, then people will of course sell. The negative affect is therefore amplified.
The tricky part of this is trying to work out the odds of success or failure and if the sentiment of this board is anything to go by, then failure is winning.
