FrankJ1987, my understanding is that they were one of the instos who participated in the previous CR. They may have taken up 4% holding and then purchased and sold up to a 5% holding.
The previous CR would have had a few instos take on large chunks but stay under the 5% reporting requirements. The most recent would have been the same also. I hope that clarifies why you have not seen the volumes to support the movements in shareholdings.
