have to agree
point of buyback is to buyback as cheap as possible

i wasnt aware (until today) that they have an upper sp limit for buyback based on avge sp over past 5 days, this is a rolling target based on last 5 days trade, so no massive line clearing just prudent accumulation.
With POO hovering around US$100 AMU should see a large turnaround in their hedge adjustments
