Ann: Revised Securities Trading Policy, page-95

I would say it is probably correlated with the SA lockdown for 2 weeks.

If it was some insider/s offloading you would probably be seeing a hell of a lot more shares than 3 mill being offloaded for anything they can get. Unfortunately I got caught out in May with another share with insider trading just before an underwhelming announcement was dropped and that was serious volume being churned through and it ended up finishing at half the price it was just a few days before the announcement. When someone is seriously offloading you will know about it, unfortunately I do from experience..

As Pennyhaul and Apep have alluded to, these small pip drops has happened so many times whilst waiting for news, just don't be the one to get caught out when the announcement could potentially drop at any time.
