Stocks End Lower as 'Cliff' Talks Turn Sour

Stocks ended near session lows Wednesday, wiping out much of the previous session's rally, as negotiations to avert the looming "fiscal cliff" turned sour after Speaker John Boehner said the House of Representatives will pass a budget proposal that President Barack Obama had already threatened to veto.

The Dow Jones Industrial Average fell 98.99 points, or 0.74 percent, to close at 13,251.97, pulling back after posting its second triple-digit rally in the previous session. General Electric and Alcoa led the blue-chip laggards.

The S&P 500 dropped 10.98 points, or 0.76 percent, to finish at 1,435.81. The Nasdaq declined 10.17 points, or 0.33 percent, to end at 3,044.36. The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, jumped above 17.

"I wouldn't be surprised to see a hard selloff after a deal is reached—sell the news," said Harry Clark, chairman and CEO of Clark Capital Management. "We're in a high-risk area—everyone's most confused than ever and the public is out of the market totally."

Boehner pressed his "Plan B" proposal that would extend the Bush-era tax cuts for those earnings up to $1 million, despite Obama's veto threat, saying it will be approved Thursday by the GOP-controlled House.

"Then the president will have a decision to make," said Boehner. "He can call on the Senate Democrats to pass that bill, or he can be responsible for the largest tax increase in American history." (Read More: Early Santa Rally? If Congress Doesn't Mess Up)

Meanwhile, Obama said the two sides were only $200 billion apart in a deal to avoid the looming "fiscal cliff," and he's ready to get the job done.

"If you look at Speaker Boehner's proposal and my proposal, they're pretty close. They're the same categories with a few differences, but we're right there," said Obama. "This is not a situation where I'm unwilling to compromise and anyone who looks at this objectively would say that I have met [the Republicans] at least halfway."

Adding to jitters, ratings agency Fitch warned that the U.S. could lose its triple-A status if Washington does not solve the "fiscal cliff" issue. The agency current has a negative outlook on its U.S. sovereign rating, while Standard & Poor's cut its triple-A status on the U.S. last August.

Herbalife plunged more than 12 percent after widely-followed hedge fund manager William Ackman said he is shorting the nutrition and skin-care products company's stock and has told people he considers the business to be little more than a "pyramid scheme." Ackman is expected to explain his reasons for the move at an investment conference Thursday. (Watch: Herbalife CEO: 'This Is a Legitimate Company')
