Subject: Re: Market house of cards based on debt
The broker will call the margin if the bet goes south but at least that’s as far as it will go.

That presumes that the underlying stock can be sold any any price. Like a “trailing stop” that sells at (say) $100, the stock could drop to $80, $50 or whatever before a buyer is found.

That kind of cascading failure would put those margin sales in negative territory, and making getting ANYONE whole a question mark.

We’re in new and dangerous territory here, Tonto.
