US stocks advanced Thursday following an upbeat retail sales report, but the gains were limited by concerns over the rapid fall in oil prices.
At the closing bell, the Dow Jones Industrial Average stood at 17,597.37, up 64.22 points (0.37 percent).
The broad-based S&P 500 gained 9.16 (0.45 percent) to 2,035.30, while the tech-rich Nasdaq Composite Index rose 24.14 (0.52 percent) to 4,709.16.
The indices were in positive territory all day, but finished below their intra-session peaks, with the Dow trading above 17,750 at times.
"Investors are watching oil and they don't know what to make of it," said Jack Ablin, chief investment officer at BMO Private Bank.
Key worries for investors include fears that a major hedge fund or bank could be hurt by a bad bet on oil, he said.
"There's a cloud hanging over the market," Ablin added.
Earlier, US government data showed that retail sales in November rose 0.7 percent in a solid start to the holiday shopping season.
