Dow ekes out 20-point gain

So much for the lousy jobs report - after being down slightly for much of the session, stocks rallied late in the day. Perhaps the market was helped along by a big jump in the euro (often a bellwether for stocks), perhaps it was increased expectations of a tax cut deal in Congress, or perhaps new developments in the European debt crisis. For the week, the Dow was up 2.6 percent.
