Once this bailout/handout craze is finished (with the Fed on Monday), the focus should be back on data, i.e., declining growth, mostly slowing earnings (with a few bright spots like MSFT) and more credit market problems.
There were only 2 major U.S. releases this week, and one of them (initial jobless claims) uses some funny math. With so little news, it was a great week for a cut and stimulus package. Wait till ISM Manufacturing, NFP, retail sales, housing data, etc. comes out, as well as who-knows-what news from the banks and monolines. Then we'll see what this rally is made of.
