This suggested "6-8 million volume dump" represents only 0.7% of GRR shares on issue. Looking at the 8 Feb 2017 Top 20 list I'd suggest that Realindex Investments might be the seller albeit speculation based on Realindex previously reduced from 55.8 million shares or 4.8% (as at March 2016) to 43 million shares or 3.7% (as at Feb 2017). As a sale of 6-8 million reduction would represents only 20% slice they would still then be holding GRR 35 million shares. No doubt the GRR Annual Report 2017 may shed some light on changes across the Top 20 but this is still months away. As any shareholders outside the Shagang Group (55%) hold more than 5% then no ASX notices are required to be lodged.
