NEW YORK (CNNMoney.com) -- Stocks gave back earlier gains to end mixed Tuesday, as investor optimism over the extension of Bush-era tax cuts gave way to speculation about a widening federal probe into insider trading.
A spike in Treasury yields also tempered enthusiasm.
The Dow Jones industrial average (INDU) fell 3 points, or less than 0.1%, to close at 11,359. The S&P 500 (SPX) ended little changed at 1,224, after climbing to a 2-year high during active trading. The tech-heavy Nasdaq (COMP) rose 3 points, or 0.1%, to 2,598.
Stocks held gains for most of the day as investors welcomed news that President Obama had reached a deal with Republican lawmakers Monday that would extend Bush-era tax cuts for two years and unemployment benefits for 13 months. It would also lower the payroll tax by two percentage points for a year.
But the momentum faded late in the day after Obama, who had wanted the cuts for high-earning taxpayers to expire, said in a press conference that he would push to have them eliminated after the two-year extension is over.
"This gives us the time to have this political battle without having the same casualties for the American people," he said.
Obama said the compromise was necessary to prevent taxes from going up for middle-class taxpayers. But it also reflects the newfound clout Republicans have on Capitol Hill following last month's upset in the midterm elections.
Peter Boockvar, chief market strategist with Miller Taback & Co., said the market turned lower following a report that the government's crackdown on insider trading is accelerating. But he said investors were also nervous about a major sell-off in the bond market.
"I think it has more to do with the shellacking in the bond market," he said. While the deal to extend tax cuts was a positive, "investors can't ignore the spike in interest rates," he added.
The yield on the 10-year Treasury note jumped to its highest level since June, stoking worries that a rising interest rates could slow the sluggish economic recovery.
Stocks ended Monday's session mixed after drifting around breakeven for most of the day. Investors spent most of the day mulling over Federal Reserve chairman Ben Bernanke's pessimistic comments about the nation's economy.
