I was actually considering subscrinig to his newsletter and then I read this report, including this paragraph, which is part of a 24 page report entitled "Dow Jones Below 1,000?" This is a prediction of technician Robert Prechter and Faber spends some time talking about what one would do if one really thought a 90% decline was in the cards (Faber is bearish but not that bearish, at least in the near term). Here is one of his thoughts:
One way to protect assets could, of course, involve short selling — in the absence of cash and bonds being “safe” with the Dow below 1,000. (As explained above, massive defaults would occur.) A $1 billion portfolio could sell short its holdings “against the box” (meaning that, for the exact same shares the portfolio is long, equal short positions would be maintained). With the Dow below 1,000, even if no transactions get settled, the portfolio would have been fully protected. However, with the Dow on its journey to 1,000, short selling will likely be banned and short positions will have to be closed out — so, again, there is no full protection
Evidently it did did not occur to him that, instead of entering into a short against the box, one might instead simply sell.
