Wall Street investors were likely to lose momentum Friday, dragged down by market uncertainty overseas, a weak report on personal income, and concerns about events -- or lack of events -- in Washington.

Assuming no last minute deal, $85 billion in automatic spending cuts are due to begin Friday, although it may be weeks or months before the pain is felt. Still, markets are likely to remain in a cautious mood as major indexes hover just below record highs.

U.S. stock futures were lower before the opening bell.

The Commerce Department reported that personal income fell 3.6% in January, which was the steepest month-to-month drop in 20 years. Personal income was expected to have dropped 2.4%, according to a consensus of economist forecasts. Personal spending notched up 0.2%, as expected.

Paul Donovan, UBS economist in London, said that recent highs on Wall Street have made stocks sensitive to lackluster markets in Europe and Asia -- particularly in China after a "softer than anticipated" manufacturing report. He also said Europe continues to be unsettled by political turmoil in Italy.

Eurostat reported the euro zone unemployment edged up to 11.9% in January. Italy's unemployment was slightly lower than that, at 11.7%, but its youth unemployment has reached a staggering 38.7%.
