Stocks surrendered their early gains and scampered back into negative territory Tuesday after the Conference Board reported that U.S. consumer confidence fell in February, pouring cold water on hopes that an economic recovery is under way.

The blue-chip Dow Jones industrial average fell 30.45 points, or 0.30 percent, to 10,115.26. The broader Standard & Poor's 500 Index was down 0.03 points, or 0 percent, at 1,109.40. The tech-laced Nasdaq Composite was off 2.92 points, or 0.16 percent, at 1,766.96.

A rumor that U.S. special forces had landed in Iraq swept through trading desks and exacerbated the mid-morning drop, traders said. But the market pared its losses after a Pentagon spokesman denied American troops were in Iraq and said the report originated with Fox News Channel.

Fox News Channel operates FOXNews.com.

The market posted gains after the opening bell, but they quickly evaporated after the Conference Board reported is consumer confidence index fell to 94.1 in February — its lowest level since November and well below expectations — from a revised 97.8 in January.

"The magnitude of the decline (in confidence) was very surprising," said Hugh Johnson, chief investment officer at First Albany Corp. "That's really worrisome. It's hard to imagine a recovery in the economy and earnings if consumers are not confident and spending money."

Lingering uncertainty about prospects for an economic turnaround has made for volatile trading as various economic reports whipsaw the market, said Eric Gustafson, portfolio manager at Stein, Roe & Farnham. "People are just very fearful of volatility and being on the wrong side of a trade."

February's drop in the consumer index helped undermine Wall Street's confidence in the economy, analysts said. Investors are paying close attention to such data because consumer spending, which has been resilient despite recession, powers two-thirds of U.S. economic activity.

The report, which is said to be watched by Federal Reserve Chairman Alan Greenspan, arrives before the the central banker begins his twice-yearly testimony on the economy to Congress on Wednesday.
