NEW YORK (TheStreet) -- U.S. stocks rallied into the close Friday, but couldn't make up for losses earlier in the week, ending with the biggest weekly decline since Aug. 1 as the S&P 500undefined failed to reclaim the 2,000 level. An upward revision to U.S. second-quarter GDP figures fueled expectations that the Federal Reserve will stay the course on ceasing QE by October and raising rates by the second quarter of next year.

The Dow Jones Industrial Average (I:DJI)  jumped 0.99% to 17,113.15, but fell 0.96% for the week. The S&P 500undefined  gained 0.86% to 1,982.85, but with a 1.37% weekly loss. The Nasdaqundefined  was higher by 1.02% to 4,512.19, ending the week lower by  1.48%.

The U.S. economy expanded by 4.6% in the second quarter, the government said Friday, matching estimates and coming in higher than the prior estimate of 4.2%.

The biggest contributor to the upward revision to overall GDP was business investment, noted Paul Ferley, RBC Economics' assistant chief economist. The growth rate for this component was raised to 9.7% from a previously estimated 8.4%, which added an additional 0.2 percentage points to overall second-quarter GDP growth. 

"I would take encouragement from this strengthening in business investment," he said. "It implies businesses are confident enough to spend and invest. This reinforces the impression provided by the sustained solid gains in employment so far this year." Ferley said Friday's GDP numbers are consistent with his view that growth in business investment will rise rise around 6.5% this year and 8% in 2015, up from a 3% gain in 2013.
