In afternoon trading on Wall Street, the Dow Jones Industrial Average dropped 1 per cent, while the Standard & Poor's 500 Index slid 0.9 per cent, and the Nasdaq Composite Index sank 1.7 per cent.
Declines in shares of Microsoft and those of Intel, down 2.7 per cent and 2.3 per cent respectively, propelled the Dow lower.
Shares of Chevron and Exxon Mobil posted the biggest percentage gains in the Dow, last up 1.4 per cent and 0.8 per cent respectively.

To be sure, oil hasn't yet found a floor. "Production might level off or even decline a bit but remain at a very high level," Kyle Cooper, director of commodities research at IAF Advisors in Houston, told Bloomberg. "The fundamentals still look really bad and I think we'll resume the move lower."
In Europe, the Stoxx 600 Index finished the session with a 1.1 per cent slide from the previous close. The UK's FTSE 100 Index declined 0.4 per cent, Germany's DAX fell 1.2 per cent, while France's CAC 40 Index retreated 1.3 per cent.
Even so, there was better-than-expected data from Germany as the Ifo institute's business climate index rose to 107.9 in March, up from 106.8 the prior month and advancing for a fifth straight month.
There was some good news for cash-crunched Greece too.
The European Central Bank approved a slight increase in the emergency funds available to Greek lenders, Bloomberg reported, citing two people familiar with the decision. On Wednesday Greek markets were closed for a holiday.
