Stock futures continued Thursday's rally on Friday after the latest data showed fourth-quarter growth in the U.S. economy wasn't as bad as feared. 

S&P 500 futures were up 0.63%, Dow Jones Industrial Average futures added 0.6%, and Nasdaq futures rose 0.75%.

The second estimate of fourth-quarter GDP was revised up to an annual rate of 1% from 0.7%, suggesting that the U.S. economy was in better shape than expected to close out last year. Economists had expected GDP to be revised down to 0.4% growth. A stronger U.S. dollar and an inventory buildup continued to hurt manufacturing, though, with exports down 2.7% and imports falling 0.6%. Consumer spending rose 2%, though less than an originally estimated 2.2%. 

Leaders from G20 nations gathered in Shanghai. Investors are hoping for clearer action from China, the world's second-largest economy, on how to boost growth and stabilize markets. Some hope that the two-day meeting could also result in a coordinated stimulus effort from member countries, a notion backed by the International Monetary Fund. However, some have already ruled out such joint efforts. 

"Talking about further stimulus just distracts from the real tasks at hand," said Germany's Minister of Finance Wolfgang Schäuble on Friday. "We, therefore, do not agree on a G20 fiscal stimulus package as some argue, in case outlook risks materialize."

Crude oil continued higher on Friday on reports that Venezuela, Russia, Saudi Arabia and Qatar had agreed to meet in March to further negotiate a production freeze. West Texas Intermediate crude was up 1.1% to $33.44 a barrel.
