Ann: Company Update and Quarterly Reporting-NOR.AX, page-130

Yeah, I agree with most of that, but I don't think there's any grand plan to acquire plenty, in fact I doubt their total holding would vary at all from month to month. I assume overall they buy and sell the same amount of shares, and sometimes that requires a quick pump to ensure overall they constantly profit off every trade. If they were actually aquiring or dumping so many, you'd assume they'd be either becoming or ceasing to be a substantial holder. It seems they just turn over shares and control the market to suit what their computer needs to work constant profits. How these bots are legal is a joke.
I might be completely wrong on how they operate, just how it seems to me lately.
