NEW YORK, Dec. 21 (Xinhua) -- The U.S. dollar traded mixed against other major currencies on Thursday as investors digested a batch of economic reports.

U.S. real gross domestic product (GDP) increased at an annual rate of 3.2 percent in the third quarter of 2017, according to the third estimate released by the Commerce Department on Thursday. In the second quarter, real GDP increased 3.1 percent.

"Third quarter GDP was close enough in this final revision for investors to move on to thinking about Q4 and 2018," FTN Chief Economist Chris Low said. "The Fed thinks GDP will grow 2.5 percent, and that appears to be the high end of Street economists' expectations."

Meanwhile, in the week ending December 16, the advance figure for seasonally adjusted initial claims was 245,000, an increase of 20,000 from the previous week's unrevised level of 225,000, the U.S. Labor Department said Thursday.

The 4-week moving average was 236,000, an increase of 1,250 from the previous week's unrevised average of 234,750.

The dollar index, which measures the greenback against six major peers, decreased 0.03 percent at 93.284 in late trading.
