US economic problems not over, sell the ‘dead cat bounce’ « Peter J. Cooper’s Weblog

This is trader terminology for something that happens in a very bad downturn. Eventually things get so bad that they recover just a little, leading to flood of false optimism about the future, partly from traders who want to use the bounce to clear their books. It is like a cat falling off a building. It will bounce upwards on impact but still be dead.
