I sometimes wonder if you see the irony of your own posts!
"..ASIC said it had observed “blatant attempts” by some local investors to pump share prices by using social media to announce a target stock or designated time to buy, and a target price or percentage gain to be reached.."
Have a read of the voluminous posts you have made on exactly that theme? Perhaps a call from ASIC is pending for you!
And the proof (if any more was needed) of your 'knowledge' of how markets work lies in your last 2 sentences. Even if you believe that anonymous posts on social media, or, public forums, influence share prices, their effect is to produce transient price fluctuations - more an example of the 'greater fool' principle at work, than anything to do with company value.
Like water, value inevitably reverts to its correct level - once the fools have been cleaned out.
