NEW YORK, Dec 22 (Reuters) - U.S. stock index futures were higher on Tuesday, extending gains from the previous session, as investors awaited a final reading on third-quarter economic growth and existing home sales data.
Existing home sales are expected to post their third straight monthly increase in November, a sign that the troubled housing market could be stabilizing. Gross domestic product is seen up 2.8 percent, according to a Reuters survey of economists.
"There's a sense that GDP could be higher than consensus, and that's helping futures," said Kim Caughey, senior equity research analyst at Fort Pill Capital Group in Pittsburgh.
"GDP will be the go-to number to get reassurance that the recession is truly over, while strong home sales will be another sign that indicators are going the right way."
