] (Updates to late morning)NEW YORK, Jan 21 (Reuters) - U.S. stocks pared gains on Wednesday, with the Dow and S&P 500 briefly turning negative as tough questions during Treasury secretary candidate Timothy Geithner's testimony raised some doubts about his confirmation.
Focus turned to a Senate hearing on Geithner's nomination, overshadowing an earlier rally that had sent the S&P 500 up over 2 percent following a solid forecast from IBM and bargain hunting in the banking sector.
Wall Street had cheered Obama's choice of Geithner when it was first announced, but the nomination has since generated some controversy. Geithner is expected to face questions about his past failure to pay some taxes.
Dave Rovelli, managing director of U.S. equity trading at Canaccord Adams in New York, said he believed the Senate will ultimately confirm Geithner, but uncertainty killed the stock rally.
The stock rally was squashed because of "the uncertainty of whether he's going to be confirmed or not, because we need someone right away," Rovelli said.
The Dow Jones industrial average <
> rose 65.79 points, or 0.83 percent, to 8,014.88. The Standard & Poor's 500 Index <.SPX> added 8.87 points, or 1.10 percent, to 814.09. The Nasdaq Composite Index < > was up 18.36 points, or 1.27 percent, at 1,459.22.Also denting sentiment was Geithner's testimony that President Barack Obama will lay out an economic stabilization plan in the next few weeks. Investors had been hoping to see the new administration hit the ground running with efforts to prevent the year-long recession from worsening.
"Geithner said Obama's economic plan will come in the next few weeks' and I think people are hoping for an immediate package now. But the fear is that it could take two to three months," said Bret Barker, portfolio manager at Metropolitan West Asset Management in Los Angeles.
Still, International Business Machines Corp <IBM.N> contributed the most to the Dow's gain, shooting up 8.7 percent to $89.12 after the world's top technology services company reported a quarterly profit and gave a 2009 profit outlook that surpassed expectations. For details, see [
