An exert from the last Hartleys research analysis ( 10th March ) has AGO valued ,for them, at $ 3.34.
To make things more interesting this valuation is if the benchmark price only goes up 30 %.
Their revised numbers for
50% increase: $4.24
80% increase: $5.58
I think this is one reason why we are starting to see the re rating coming in thick & fast.
