NEW YORK (MarketWatch) -- U.S. stocks sold off sharply in late trade Monday, resulting in the worst losses for benchmark indexes in several months on concerns about the December jobs report and more discussion of the Federal Reserve's bond taper.

Weighing on sentiment were comments from Atlanta Federal Reserve president Dennis Lockhart in support of further tapering to the one already announced in December.

The Dow Jones Industrial Average (DJI) suffered the worst one-day drop since Sep 20, shedding 179.1 points, or 1.1% to 16,257.94 by the close, falling for the fourth-straight session. .

The S&P 500 index (SPX) closed down 23.17 points, or 1.3% to 1,819.20, snapping its two-day winning streak. The Nasdaq Composite (RIXF) finished 61.36 or 1.5% lower at 4,113.30. Both the S&P 500 and Nasdaq saw their worst one-day points drop since Nov 7.

In a speech to the Rotary Club of America, Atlanta Fed president Lockhart said he supports "similar tapering steps" as the one taken to reduce bond-market purchases by $10 billion by the Federal Reserve last month, so long as the economy grows at the 2.5% to 3% clip he's forecasting this year.

He pointed out that the labor market is not as healthy as a 6.7% unemployment rate suggests as he also said continued disinflation could pose risks to economic performance. Follow stock market live blog here.

On Friday, the government reported that the U.S. economy added 74,000 jobs in December, the smallest gain in three years and well below economists' forecast of about 200,000. The unemployment rate fell to 6.7%, however, largely due a large number of people dropping out of the labor force. Investors were undecided whether this should be taken as a negative or positive for markets, as stocks fluctuated in an narrow range on Friday, closing mostly higher.

In separate news, the federal government recorded a budget surplus of $53 billion in December, the Treasury Department reported Monday. Nearly $40 billion in payments from government-controlled mortgage giants Fannie Mae and Freddie Mac helped the surplus, the largest on record for the month of December. The surplus brings the government's budget deficit for the first quarter of fiscal 2014 to $174 billion, 41% lower than the first three months of fiscal 2013.

In a research note from David Kostin at Goldman Sachs, wrote that the S&P 500 valuation is looking "lofty by almost any measure."

Chaning Smith, managing director at Capital Advisors, said that markets are playing catch-up with the bond market, finally realizing that the jobs numbers were fairly bad.

"Investors are also nervous ahead of earnings releases from the banks tomorrow and if the results miss expectations, there will be a lot more pressure on the markets," he added.

J.J. Kinahan, chief strategist at TDAmeritrade said that markets are having a delayed reaction to the jobs data.

"When payroll numbers came in, we all thought that the first digit was missing, then realized that it was just 74,000. Market reaction to that number on Friday was anomalous, as they shrugged them off. Today buyers that usually came in the afternoons were absent and people were taking profit and lightening their positions in an anticipation of earnings results," Kinahan added.

* Comment: Nicholas Colas, chief market strategist at ConvergEx Group, a global brokerage company based in New York, wrote in a note: "The most disappointing number from Friday's Employment Report was not the miss to jobs growth expectations (74,000 versus the hoped for 200,000), but rather the continued precipitous decline in labor force participation. At 62.8%, this measure of people actually working or looking for employment has slumped back to the levels of the 1970s economic malaise. More importantly, the trend here has outstripped the U.S. Government's forecasts, which only called for such a level around 2020. January 2013 may not see any improvement if Congress does not extend emergency unemployment benefits, with participation dropping further if the long-term unemployed chose to exit the workforce as a result. That would leave the Fed with an unwelcomed communications problem: quickly drop the 6.5% threshold unemployment rate from its monetary policy, or risk being seen as out of touch."

Shares of Twitter Inc. rose as high as 4% but eased by late trade and closed 1.4% after Goldman Sachs lifted its price target for the social media network to $65 from $46 and maintained a buy rating. Wendy's Co.shares rose 6.4%, as the fast-food company's expected adjusted earnings per share were higher than analysts expected.
