I can’t say I have ever seen much evidence when posters roll out the “engineered sell off” conspiracies.
It is probably a lot more basic than you would like to think. If the market price declines, that can trigger stop loss, it can trigger nervous holders who want to lock in a profit, fewer buyers means the price goes down. That’s all that happens here IMO. There had to be quite a few new shareholders jumping in during this latest tid-bit of news, some buying the story up to 10.5c. All buyers would be losers above 0.065 so far. If there is another news story to come out in the near term, 6c might hold.
But if not, a long steady grind back to 2c or less should eventuate.
