The exiting of a disgruntled large holder would be a mildly comforting reason for the SP drop, but I'm not able to see this in the sparse Top 20 lists that the company publicise. In fact, your post alerted me to the fact that OBJ only publicise the top 20 once per year, in the Annual Report.
I'm scanning through the 2014, 2015, 2016 to find an entity that has been selling in the manner you describe. Although there's no one that went from +20mil to 0, there is 'Charmed5 PL' that went from 17mil to 15mil in the 12 months prior to the 2016 Annual Report.
Any idea who this Top 20 shareholder exiting is? There are usually less than 7 entities with >20 mil shares.
Bonus points if you can post a more recent Top 20 than Sept 5th
Cheers
