NEW YORK ( TheStreet) -- Stocks extended their losses Thursday after the U.S. added a tepid 223,000 jobs in June and wages failed to show growth.

Economists were expecting about 230,000 jobs to be added to payrolls.

The S&P 500 declined 0.29%, the Dow Jones Industrial Average lost 0.37%, and the Nasdaq fell 0.37%.

The unemployment rate dropped to 5.3% from 5.5% in May. Average hourly wages remained unchanged during the month and are higher by 2% over the past year.

"The slower growth in average hourly earnings reflects the fact some 55% of the new private sector jobs were in lower paying sectors -- temp, retail, health, and restaurants," wrote ITG Chief Economist Steve Blitz. "The economy to service those who can afford leisure and those aging into higher health care needs continues to expand."

The jobs numbers for May were revised downward to 254,000 from a previously reported 280,000. April's figures were also lowered to 187,000 from 221,000.

U.S. weekly jobless claims rose 10,000 to 281,000 for the week ended June 27. The consensus was 270,000. Meanwhile, U.S. factory orders fell 1% in May, while analysts were looking for a 0.3% decrease.

Crude oil rose 0.42% to $57.27 a barrel. For the week ended June 26, natural gas in storage increased by 69 billion cubic feet, according to the Energy Information Administration. Plus, the number of U.S. oil rigs posted its first increase since December. As of July 2, 640 rigs were in operation. 

Whole Foods (WFM) shares slumped 0.53%. Co-CEO John Mackey admitted overcharging customers after New York City's Department of Consumer Affairs found evidence of mislabeling on various prepackaged items.

Investors were also grappling with developments in Greece. No negotiations between the debt-laden nation and its creditors will be held until after the Sunday referendum in which citizens will vote on whether or not to accept austerity measures. Polls from euro2day.gr show 47% of respondents voting "yes" while 43% voting "no."

"I think the market is probably underestimating the chance of a 'no' vote," Michael Ingram, a market analyst with BGC Partners, told TheStreet TV. "The vote on Sunday almost doesn't matter because it's essentially between a recession via a 'Grexit' or a depression by signing up for further austerity."
