After "Irene" attack

DJIA chart as 25/01/10 - 25/01/11

As 08/02/11

DJIA as 30/08/10 - 29/08/11

As 29/08/11

You can see the slide down graph of DJIA is cause of  S & P downgrade the US debt rating from triple A to double A plus early this month.
But my opinion is US stock exchange market will still uptrend after all.
