I've never seen a company where the top 20 hold 90%.
It leaves only around 40m shares available and who knows how much of that was gobbled up yesterday above ASFs 73 million which was taken out by the mystery party. After yesterday's buying after the big exchange the buying continued strongly so maybe the 40 million left will only be 20 million.

Could this mean that people will have to chase this much higher to get any shares on good news because nothing was available before so maybe soon there will be no shares available again but this time with lots of buyers waiting in the wings.
I hold my shares for years so am looking for a long term nest egg investment.

Thoughts?
