If he has to divulge his divestment it’s going to go to 0 before he can sell it all. If he doesn’t need to divulge it, it’s still going to go close to zero because the market for that stock won’t hold if 60% of it hits the market. If he’s been able to borrow against it, he’ll probably default and leave his lenders holding the bag.
It’s one of the core principles of fascism. The enemy is at once weak, feeble, and inferior yet simultaneously powerful, cunning, and insidious.
