NEW YORK, Nov 19 (Reuters) - U.S. stock index futures started a holiday-shortened week higher on Monday, with signs of progress in Washington talks to resolve the fiscal crunch lifting investors' mood.
Leading Democratic and Republican lawmakers expressed confidence on Sunday that they could reach a deal to avert the "fiscal cliff" even as they laid down markers on raising taxes and spending cuts that may make any agreement more difficult. European stocks also reacted by rising from a 3 1/2-month low.
Democratic Senator Dick Durbin said on CNN, "What I hear is a perceptible change in rhetoric from the other side."
Also appearing on CNN, Republican Representative Tom Price said, "Every member of our caucus appreciates that this fiscal crisis, this challenge that we have, is ever closer." Opinion polls show that Republicans would shoulder more of the blame if the country goes over the fiscal cliff.
"A deal that doesn't face healthcare spending head on and also raises taxes of substance with economic growth mediocre is not a good deal. This said, the markets will celebrate any deal in the short term but will likely deal with the economic consequences in 2013," said Peter Boockvar, managing director at Miller Tabak & Co in New York.
S&P 500 futures rose 7.4 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures added 61 points and Nasdaq 100 futures rose 16 points.
