Sure, they've known of the possibility of a big rally on capture of one of the bad guys. They've also known of the possibility of a HUGE drop if there is very bad news, such as a really serious terrorist event, or an assassination.
Being a hedger myself, I've been more concerned about the bad news than about the good news. Looks like, for the moment, my concerns were misplaced...
Hard work often pays off over time,
but laziness always pays off right now.
