Today was a mixed trading day on somewhat light trading pre-holiday volume throughout most of the trading day and there was no real feeling for a positive or negative close until the afternoon. A drop of 11% in new house sales in November added concerns over the housing recovery. This was in contrast to personal income and spending rising 0.4% and 0.5%, respectively, in November. Oil had a solid day with a $2.22 gain to $76.62 close on big inventory draw-downs.

Here were today's unofficial closing bell levels:

Dow 10,466.44 +1.51 (0.01%)
S&P 500 1,120.59 +2.57 (0.23%)
Nasdaq 2,269.64 +16.97 (0.75%)

The markets were very mixed going into the close and which direction the closing bell was going to be was not known until right at the close. Core consumer inflation seems to still be contained, although oil rose sharply today on supply and refining concerns. Even the FOMC decision to keep rates at the near-zero policy and keeping the "extended time" phrase on for extremely low fed funds rates did not hurt the markets today.

Here were today's unofficial closing bell levels:

Dow 10,441.12 -10.88 (-0.10%)
S&P 500 1,109.18 +1.25 (0.11%)
Nasdaq 2,206.91 +5.86 (0.27%)
