Yes unfortunately the hardest thing to learn in owning shares, is sometimes you have to feel some SP pain and hold some paper losses. Just ask APT buyers in Feb how they were feeling end of March.
Trouble is so many people take all the stress of the paper losses, and the moment the SP is on a run, sell out at or close to their entry price and miss out on the rent the shares owe them for owning. I learnt it the hard way along while ago on other companies.
If the demand was truly for $500m from instos then this should go on a tear in the next couple of days, as long as the overall market is favourable.
It was day 2 on the MC news where it really went for it.
