Markets opened lower this morning, and a modest gain of 80,000 non-farm jobs and a slight improvement of the US unemployment rate to 9.0% didn’t lift investors’ spirits before the opening. Today’s confidence vote in Greece kept financial stocks down as investors try to figure out what it will mean if the Greek prime minister is booted out and the country doesn’t accept the latest batch of austerity tied to the country’s $180 billion bail-out package. The IPO of Groupon Inc. (NASDAQ: GRPN) went off at $20, with shares rising to $31.44 before pulling back to $26.11 in the last half hour of trading. Crude oil is basically flat and gold has pulled back less than -0.5%. The dollar is slightly stronger against both the euro and the yen, putting weight on commodities.

The unofficial closing bells put the DJIA down more than 61 points to 11,983.32 (-0.51%), the NASDAQ fell more than 11 points (-0.44%) to 2,686.15, and the S&P 500 fell -0.63% or more than 7 points to 1,253.23.
