NEW YORK (Reuters) - U.S. stock index futures pointed to a modestly higher open on Tuesday, with the benchmark S&P 500 index set to continue a rally fueled by hopes of a deal on Greek debt and by firmer oil prices.
Stocks rallied late in the prior session on signs Greece was softening its approach to debt negotiations. A source told Reuters that Greek Finance Minister Yanis Varoufakis, in London to reassure private investors he was not seeking a showdown with Brussels over a new debt agreement, said the new left-wing government would spare privately held bonds from losses.
Adding support was a further gain in oil prices, with U.S. crude up 2.4 percent to $50.76 and Brent up 2.7 percent to $56.21. The advance came after BP

The S&P 500 <.SPX> is still down more than 3 percent from its Dec. 29 record high amid lackluster corporate earnings and data showing the U.S. economy growing at a slower pace than investors anticipated. January's 3.1 percent decline was the worst monthly performance for the index in a year.
According to Thomson Reuters data through Monday morning, of 226 companies in the S&P 500 to report results, 73 percent beat expectations. The expected growth rate for the quarter sits at 5.4 percent, down from 11.2 percent expected on Oct. 1.
