As expected, GDP growth in Q4 was driven by changes in private inventories, adding 3.39% to GDP.

From the BEA:

Real gross domestic product -- the output of goods and services produced by labor and property located in the United States -- increased at an annual rate of 5.7 percent in the fourth quarter of 2009, (that is, from the third quarter to the fourth quarter), according to the "advance" estimate released by the Bureau of Economic Analysis.
...
The increase in real GDP in the fourth quarter primarily reflected positive contributions from private inventory investment, exports, and personal consumption expenditures (PCE). Imports, which are a subtraction in the calculation of GDP, increased.

The acceleration in real GDP in the fourth quarter primarily reflected an acceleration in private inventory investment, a deceleration in imports, and an upturn in nonresidential fixed investment that were partly offset by decelerations in federal government spending and in PCE.
...
Real personal consumption expenditures increased 2.0 percent in the fourth quarter, compared with an increase of 2.8 percent in the third.
...
Real nonresidential fixed investment increased 2.9 percent in the fourth quarter, in contrast to a decrease of 5.9 percent in the third. Nonresidential structures decreased 15.4 percent, compared with a decrease of 18.4 percent. Equipment and software increased 13.3 percent, compared with an increase of 1.5 percent. Real residential fixed investment increased 5.7 percent, compared with an increase of 18.9 percent.

This is very close to my expectations and shows a fairly weak economy (real PCE increase 2.0%). The question is: what happens in 2010?

I'll have some more on GDP and investment later ...
