NEW YORK, Nov 29 (Reuters) - U.S. stocks finished higher on Thursday as investors bought on sporadic dips in a market roiled by conflicting comments from Washington about negotiations on an agreement to avoid the "fiscal cliff."
Tech shares, including Research In Motion and Advanced Micro Devices, helped the Nasdaq outperform the broader market. Telecommunications and health-care stocks were the day's best-performing sectors.
Reflecting the uncertainty surrounding U.S. budget talks, trading was choppy. Wall Street reversed early gains and fell shortly after House Speaker John Boehner, the top Republican in Congress, dashed hopes that lawmakers were getting closer to a budget deal that would avert automatic tax increases and spending cuts set for early 2013 - the fiscal cliff - that could push the U.S. economy into a recession next year. But the market rebounded by afternoon and the three major U.S. stock indexes rebounded to near their session highs.
"There is an emotional part in buying on the small dips here. Investors are more worried about missing the rally than losing money as they believe that the 'fiscal cliff' will be solved eventually," said James Dailey, portfolio manager at TEAM Asset Strategy Fund in Harrisburg, Pennsylvania.
"Until the fiscal cliff is solved, the madness of the crowd will not subside."
Discussions on Capitol Hill are aimed at avoiding big automatic spending cuts and tax hikes, known as the fiscal cliff, that will start taking effect beginning in January.
Boehner's comment about a lack of progress in talks with the White House was one of a series of contrary pronouncements by lawmakers and the Obama administration over whether Washington will finally cut a deal.
There have been some signs that leaders are moving closer to a fiscal agreement. The S&P 500 has gained about 5 percent recently after a sell-off that took it down almost 8 percent following the U.S. election on Nov. 6. But investors remain wary that politicians' ad hoc statements can spark quick reversals in the market.
U.S.-listed shares of BlackBerry maker Research In Motion rose 4 percent to $11.54 after Goldman Sachs upgraded the stock to "buy" from "neutral" on optimism ahead of the launch of the BlackBerry 10 smartphone.
Advanced Micro Devices Inc shares gained 4.1 percent to $2.04 on plans to sell and lease back its campus in Austin, Texas. The sale and lease-back will raise cash and fund its chipmaking business as Advanced Micro Devices diversifies beyond the struggling PC industry into new markets.
The Dow Jones industrial average rose 36.71 points, or 0.28 percent, to 13,021.82 at the close. The Standard & Poor's 500 Index gained 6.02 points, or 0.43 percent, to 1,415.95. The Nasdaq Composite Index advanced 20.25 points, or 0.68 percent, to close at 3,012.03.
