U.S. crude sank 2.7 percent after Goldman Sachs said that the global glut of oil supply could push prices as low as $20 a barrel. Drillers had some of the biggest losses in early trading. Rig operator Transocean slid 3.7 percent.

That sent energy stocks sharply lower. Energy shares in the S&P 500 sank 1.4 percent, nearly three times as much as the broader index.

ZIG-ZAG-ZIG: Major indexes are on track to finish the week solidly higher following deep losses last week. News about China's slowing economy and other concerns have knocked the market down 7 percent over the past month. It has been a staggered fall, with sharp drops one week followed by slight gains the next.

CHINA: Before traders return to their desks on Monday, a large batch of Chinese economic news will come out over the weekend. Joshua Mahony, market analyst at IG, said that could lead to a turbulent start to trading next week.

"The weekend release of Chinese retail sales, industrial production and fixed asset investment numbers means that Monday is likely to start with a bang," Mahony said. "And if recent data is anything to go by, it will most likely point towards yet more trouble in the beleaguered Asian powerhouse."

BONDS AND CURRENCIES: Prices for U.S. government bonds rose, pushing the yield on the 10-year Treasury note down to 2.18 percent from 2.23 percent late Thursday. The euro slipped to $1.1288 while the dollar was flat at 120.71 yen.
