Technology stocks sell off

U.S. stocks erased opening gains and edged lower on Wednesday, building on steep losses from the previous session, as Federal Reserve Chairwoman Janet Yellen remarked that stock values are high at an event in the morning.

Traders already had been fretting after a lower-than-forecast ADP employment raised nervousness among investors ahead of the more closely followed nonfarm payrolls report slated for Friday.

Implied volatility on the S&P 500, as measured by the CBOE Volatility index -- a measure of investor nervousness--jumped above 15, suggesting investors are getting jittery.

The S&P 500(SPX) fell 10 points, or 0.5%, to 2,079 with nine of its 10 main sectors trading lower. The energy sector was the only bright spot following a jump in oil prices. Technology stocks continued to pull back.

The Dow Jones Industrial Average(DJI) is down more than 100 points, or 0.6%, to 17,814. The Nasdaq Composite(RIXF) lost 24 points, or 0.5%, to 4,916.

Yellen's comments came at a panel discussion Wednesday (http://www.marketwatch.com/story/yellen-sees-dangers-in-quite-high-stock-valuations-2015-05-06) with the head of the International Monetary Fund, Christine Lagarde and didn't help lift investors' spirits.

Investors had been digesting a report, released before U.S. stocks opened for trading, which showed the pace of hiring in the private sector slowed in April. Meanwhile, productivity slumped for the second quarter in a row. Some economists dismiss the ADP report as it has little predictive power for the official nonfarm payrolls due on Friday.

Data: The U.S. created 169,000 private-sector jobs in April, payrolls processor ADP said, after a downwardly revised 175,000 jobs were created in March, well below the consensus estimate. A slowing pace of job gains may prompt the Federal Reserve officials to delay raising interest rates after the June meeting.

U.S. productivity in the first quarter fell by a 1.9% annual pace, resulting in the first back-to-back drop since 2006. The decline in productivity stemmed from companies hiring more workers and employees working longer hours even as production of goods and services declined.

Earnings:Wendy's Co.(WEN) released first-quarter adjusted earnings per share that slightly beat consensus, but revenue missed forecasts. Still, shares jumped 4.9%.

SodaStream International Ltd.'s(SODA) first-quarter earnings met FactSet consensus estimates, but revenue came short of forecasts. Shares fell 5.8%.

Shares of Herbalife Ltd.(HLF) climbed 16% after the nutrition-supplement maker late Tuesday raised its outlook for the year (http://www.marketwatch.com/story/herbalife-raises-guidance-as-earnings-grow-48-2015-05-05-174852122) as earnings rose a stronger-than-expected 4.8% in the first quarter.

Internet stocks were taking a beating on Wednesday. Twitter, Inc., LinkedIn Corp and Yelp Inc. were down more than 1.6%.

Groupon Inc.(GRPN) dropped 4.8% after the online deal company on Tuesday said its first-quarter loss narrowed (http://www.marketwatch.com/story/groupon-adjusted-profit-sales-in-line-with-views-2015-05-05).

Shares of Synageva BioPharma Corp.(GEVA) soared 114% after news Alexion Pharmaceuticals Inc. (ALXN) will buy the biotech firm in a cash-and-stock deal valued at $8.4 billion (http://www.marketwatch.com/story/alexion-to-buy-synageva-in-84-billion-biotech-deal-2015-05-06). Alexion shares lost 8.5%.

The dollar (DXY) was pushing lower against other major currencies, particularly the euro which broke $1.13 against the buck.
