Somebody seems to be accumulating. It could be Wellington Management increasing its holding, because, seemingly, it does not have to report each change per day of change. The Corporations Act 2001, Section 671B, probably covers the issue of updating the market, but I did not look at the legislation. For example however, on 19/09/2017 IFL announced that on 15/09/2017 there was a change in the interest of its substantial holding in TGA, which I hold, whereas the announcement recorded 25 days of change in the period 1/03/2017 to 15/09/2017 to effect a net decline of 1,549,916 shares – 9,526,614 (6.02%) to 7,976,698 (5.009%).
