I agree, the end of year dust off could be a significant driver for the other changes in substantial holdings. Several large holders realizing their capital losses to offset other capital gains before the end of the financial year and minimize CGT. If this is the case, I would consider it a positive they've held right until the end potentially expecting some stronger prices. Now it will be interesting to see if any of these holders look to refill their positions.
