Applied Materials, the top gainer on the S&P, rose more than 10 percent after the company beat earnings expectations despite reported drops in both earnings and revenue. The company admitted that the IT-spending slowdown has hurt business but offered a glimmer of hope: Demand for chips used in flat-screen TVs and computer screens is strong.

Retail sales were the reason du jour for investors to bid up the broader market.

Retail sales rose 0.3 percentlast month from December, largely reflecting increases in sales of new cars and gasoline. Economists had expected the gauge to drop by 0.4 percent. Excluding autos, gasoline and building materials, retail sales climbed 0.2 percent.

"As much as people want to get excited about this number, the same theme is there, which is that the U.S. consumer is slowing rapidly from the fourth quarter into the first quarter," Drew Matus, an economist at Lehman Brothers, told CNBC. "The rest of the first quarter is probably not going to look so great."

"The headline [retail] number doesn't account for promotional activity," David Turner, a retail analyst with BB&T Capital Markets, told CNBC. "Sales may look good, but I don't think the profits are following suit."

The rally was likely due to the fact that the market was expecting retail sales to decline, which would've been the second straight month-to-month drop, something that hasn't happened in five years that would suggest that the economy was slipping into recession.

Retail analysts still have some picks in the sector. Turner likes Pacific Sunwear, Skechers and City Trends, all based on valuations.

Charles Grom, a retail analyst at J.P. Morgan, is long Costco -- which has a 55 percent mix of food in its product line -- and J.C. Penney. He told CNBC that he thinks the department stores are headed for a rally. Grom is underweight on Family Dollar, Dollar Tree and Wal-Mart because they're "value traps" that are already up about 20 percent.

Elsewhere in retail, Sears Holdings said it's cutting 200 support-function jobs, which represents about 4 percent of its headquarters staff. The operator of the Kmart and Sears chains last month warned that fourth-quarter profit would decline amid a drop in holiday sales. The company let its CEO go last month and billionaire investor Eddie Lampert has come under fire for failing to turn around the struggling retailer after engineering the Kmart-Sears merger.

Treasury Secretary Henry Paulson offered the market some encouragement, repeating his view that the U.S. economy will avoid recession this year, though it will grow at a slower pace. He also said that Treasury will act quickly to distribute tax rebates.

However, Paulson said he thinks the markets have not yet digested the full effects of the housing downturn.
