The big macro can cause big moves in the market. What does today's headline macro news mean for your portfolio?

What's happening: The U.S. Bureau of Economic Analysis released its "advanced" estimate for third-quarter gross domestic product today. GDP growth clocked in at 2.5% after creeping along at a lackluster 1.3% rate in the second quarter.

In plain English, please: Gross domestic product is widely used as the main gauge of economic growth, so when pundits talk about the U.S. economy growing (or not), they usually have GDP in mind.

Depending on whom you ask, economists were expecting this GDP reading to come between 2.3% and 2.7%, so the 2.5% reported was basically in line with what the market was already anticipating. While that could be a pretty ho-hum announcement, economic numbers have been disappointing enough lately that even an as-expected outcome from a major indicator like this is likely comforting to investors.

Of course it's notable that this isn't called an "advanced" reading for nothing. On Nov. 22, another reading based on a broader set of data will be released, and no doubt investors will key in on that to make sure that the first pass wasn't way off the mark.

Stocks to watch: Powering the GDP gains in the third quarter were personal consumption expenditures and nonresidential fixed investment. In particular, durable goods -- household appliances, consumer electronics, autos -- were particularly strong after a weak showing in the second quarter. Potential investable ideas on that would include Apple (Nasdaq: AAPL), Ford (NYSE: F), and Whirlpool (NYSE: WHR). Meanwhile, with nonresidential structure spending up 13.3% in the quarter and equipment and software gaining 17.4%, investors could consider business software and equipment suppliers like Oracle (Nasdaq: ORCL) or EMC (NYSE: EMC), or materials and construction-related companies like Cliffs Natural Resources (NYSE: CLF) and Caterpillar (NYSE: CAT).
