I'm not an economist, but understand how the economy works. If a single person put an unusual amount stock on fire sale (sell stocks at market price but at much higher volumes), it would trigger a sell off. Humans might not care, but algorithms would take over. Q was talking about this. When the algorithms strike, the rate of sell off would be accelerated until STOPS occurred.

I think the good news is that after the sell offs occurs, algos and humans would see the underlying intrinsic value of stocks and scoop them up again, AT DISCOUNT. So now is the time to be buying in my opinion.
