FRANKFURT (MarketWatch) -- U.S. stock futures traded marginally lower on Monday, giving up earlier gains, as positive economic data and a pledge to cut government deficits were not enough to sustain market sentiment.
Futures on the Dow Jones Industrial Average fell 16 points to 10,088. S&P 500 futures dropped 1.10 to 1,073.60 and Nasdaq 100 futures fell 3.25 points to 1,836.
Most major U.S. stock indexes finished slightly higher on Friday.
Earlier in the session, stock futures had gained, as leaders of the world's advanced economies pledged over the weekend to halve their government deficits by 2013.
Meeting in Canada, leaders of the Group of 20 major economies also vowed to stabilize or reduce the ratios of government debt to gross domestic product by 2016.
The G-20 warned that synchronized fiscal adjustment across several major economies could adversely impact the recovery. As a result, fiscal consolidation plans should be differentiated to national circumstances and focused on growth-boosting measures. Read more on the G-20 summit.
Lars Christensen, chief analyst at Danske Bank, downplayed the importance of the G-20 commitments.
"I don't think the G-20 has changed a lot in terms of market sentiment," Christensen said. "The world picture is still one of caution. We saw a little bit of stabilization on Friday and that carries through today as there is a lack of much news."
He said that in the low-liquidity summer markets, the World Cup in South Africa appears to be dominating the news more than any other issues.
For markets, however, "the European sovereign debt crisis is still the story," Christensen said. "For now, Europe is the weak link in the global economy."
In the U.S., the Commerce Department said Monday that the savings rate for American households rose to the highest level in eight months in May. Personal incomes also increased.
