I expect this morning the President's Working Group on Markets (a/k/a/ 'The Plunge Protection Team') has been up & at-'em early in order to hold the futures where they were when I looked as I started writing - holding a dozen , or so, points over the psychologically important 8,000 level.
It's pretty safe to assume that we won't copy the 22.68% drop of the Dow Industrials experienced then. Oh, not that there's not plenty of fear and trepidation out there. Nope. Just that circuit breakers will click in and let everyone go out for beers long before that.
