Super interesting, thanks for the data and breakdown. Quick glance, your figures look correct. Building on this a bit:
Over period 18th March to 1st April:
Top 20 Total Buys = 45.5m
Top 20 Total Sells = 37m
Total volume bought/sold from top 20 holders then during this timeframe = 82.5m
From previous post (
https://hotcopper.com.au/threads/general-thoughts.7495348/page-8568?post_id=78465828) we determined that over the 18th march to 28March (close enough) timeframe we hade circa 555m shares change hands. Thus, the Top 20 made up 15.86% of all units that changed hands during this 2 week period. The remaining circa 85% of turnover occured outside of the top 20.
Also, to match your recent top 20, here is broker data for the same time period. Its tough to actually trace every buy to every sell (and vice versa), but some interesting observations can be made here. I particularly thought the Wealthhub 'buy trade' column interesting - 4955 buy trades! (clearly this is one of the algos). I'm sure there's heaps of other interesting datapoints - but for now, the company really needs that fundemental catalyst, and clear journey forward towards a drill (sooner rather than later hopefully).
