Never mind “why are they dumping stocks”.
Why are they all building fortified farmsteads on the South Island of New Zealand?
You beat me too it, forget the stock moves. Why has pretty much every billionaire build apocalypse bunkers in a remote island on the other side of the world off the plane of the ecliptic mind you. Why is that important because nearly every major comet and asteroid orbits in or near the solar plane of the ecliptic the odds of an astrological impact are lowest at the poles and next lowest is far as one can be from the plane of the ecliptic guess where New Zealand falls.
Cheap insurance, bragging rights, etc
“Why are they all building fortified farmsteads on the South Island of New Zealand?”
They’re building nothing. It’s a cover story to lure all the starving survivalists looking for peanut butter for their hardtack. All they’ll find in New Zealand is penguins and kiwis, neither of which make yummy sandwiches.
