Unfortunately this implied "downgrade = stock plunge" association seems to be everywhere this morning with no mention that long term interest rates for US debt have actually dropped. Well, if everyone believes that downgrade --> stock plunge, or even if a sufficient number of people believe that downgrade --> stock plunge, then it's no surprise that downgrade --> stock plunge. I think the smart money will be hunting bargains. Pity I don't have any right now.
