NEW YORK (TheStreet) -- U.S. stocks moved sharply higher on Wednesday as the technology sector rebounded after a week of market pressure. 

The S&P 500 was up 1.7%, the Dow Jones Industrial Average climbed 1.5%, and the Nasdaq added 2.1%.

The Nasdaq enjoyed its best daily gain in three weeks as the tech sector rallied.

Manufacturing activity in Chicago fell sharply in September to its weakest reading since May. Chicago PMI fell to 48.7 over the month from 54.4 in August. Economists had expected a slight decline to 53. Chicago manufacturing has a strong correlation with the national ISM index which monitors the overall U.S. manufacturing sector.

Major benchmark indexes were on track for quarterly losses of around 9% after facing a range of worries over the past three months. Prime among them, China's devaluation of the yuan and further signs of a slowdown in the world's second-largest economy that rocked markets since August. The performance is its worst since the third quarter of 2011 when the S&P 500 lost 14% as a Europe's debt crisis crushed global markets. 

The U.S. economy added 200,000 private sector jobs in September, above expectations for an increase of 190,000. However, August's job gains were revised down to 186,000 from 190,000, according to the ADP jobs report. The official jobs report from the Labor Department will be released on Friday.
