It's another up and down day for stocks, but that's become status quo for markets lately. The big development on the fiscal cliff today was "constructive" talks between the White house and Congressional leaders this morning, which gave investors a little hope that we may get some sort of reasonable solution. Markets perked up from early losses, and near the end of trading, the Dow Jones Industrial Average (DJINDICES:^DJI) is up 0.12% and the S&P 500 (SNPINDEX:^GSPC) has gained 0.20%.

United Health Group (NYSE:UNH) is the Dow's biggest winner, climbing 1%.
