NEW YORK – Stocks rose at the open on Wednesday after a sell-off the previous session left indexes at 12-year lows, with a jump in the price of oil and other commodities spurring energy and natural resource stocks.

Investor optimism was also buoyed by news suggesting China, the world's third-largest economy, may be on the brink of recovery, while a rebound in Asian and European stocks added to the positive tone.

U.S. private sector job losses accelerated in February, according to a report by ADP Employer Services that came in worse than economists' expectations. ADP said private employers cut 697,000 jobs versus a revised 614,000 in January, for the biggest loss since the report's 2001 launch.

The Dow Jones industrial average (.DJI) gained 106.73 points, or 1.59 percent, to 6,832.75. The Standard & Poor's 500 Index (.SPX) rose 10.80 points, or 1.55 percent, to 707.13. The Nasdaq Composite Index (.IXIC) added 19.73 points, or 1.49 percent, to 1,340.74.
