US stocks tumbled Monday after last week's disappointing jobs report showed a slowdown in hiring that raised concerns about the strength of the economic recovery.
The Dow Jones Industrial Average fell one per cent as Wall Street got its first chance to react to the government's labour data, released when the US markets were closed for Good Friday.
The sell-off "is understandable" after the government reported the economy created a meagre 120,000 jobs in March, well below analyst forecasts of 200,000, said Dick Green at Briefing.com.
"That was indeed a disappointment and while still a solid increase, reduces the underlying optimism towards the economic outlook that had been created by three straight prior months of in excess of 200,000," he said.
The Dow finished the session at 12,929.59, down 130.55 points.
The broad-market S&P 500 shed 15.88 points (1.14 per cent) to 1,382.20, while the tech-heavy Nasdaq dropped 33.42 points (1.08 per cent) to 3,047.08.
The weak US jobs report raised speculation that the Federal Reserve may yet have to apply fresh stimulus to juice growth.
"Markets may ratchet up expectations for additional quantitative easing by the Fed, but we believe the odds are less than 50 per cent," said Ryan Sweet at Moody's Analytics.
Investors awaited a speech by Fed chairman Ben Bernanke in Georgia later Monday, on the subject of fostering financial stability.
Financial stocks took a beating. Bank of America shed 3.3 per cent, Morgan Stanley (2.2 per cent), Citigroup (2.4 per cent) and JPMorgan Chase (1.0 per cent).
Shares of AOL skyrocketed 43.3 per cent to $US26.40 after the struggling internet pioneer announced it would sell more than 800 patents to Microsoft in a $US1.06 billion ($A1.04 billion) deal. Microsoft fell 1.3 per cent.
In other corporate news, telecom giant AT&T said it was selling its Yellow Pages unit called YP Holdings LLC to the equity firm Cerberus in a deal worth $US950 million. AT&T shares slipped one per cent.
Door-to-door beauty products seller Avon lost 3.1 per cent after announcing a new chief executive, Sherilyn McCoy, snatched from Johnson & Johnson.
