Wall Street was higher after swinging between gains and losses on Thursday as a fall in healthcare stocks capped gains in technology and energy shares. The S&P health sector was the biggest loser, while the Nasdaq biotech index was on track for its biggest monthly fall in 16 years with a 3 percent fall. Abbott Labs was the biggest drag on the healthcare sector, with an 8.8 percent drop.
However, the energy sector was buoyed by the rise in crude oil, which held steady near $34 a barrel, gaining nearly 3 percent. Oil had risen as much as 6 percent earlier on speculation that Saudi Arabia and other Opec countries would cut output to boost prices. "Oil's been firmly in control of the market," said Kim Forrest, senior equity research analyst at Fort Pitt Capital Group in Pittsburgh.
"I think what oil has become is a proxy for 'are we going into a recession?'," she said. At 12:59 pm ET (1759 GMT), the Dow Jones industrial average was up 67.9 points, or 0.43 percent, at 16,012.36, the S&P 500 was up 10.65 points, or 0.57 percent, at 1,893.6 and the Nasdaq Composite index was up 38.52 points, or 0.86 percent, at 4,506.69. Nine of the 10 major S&P sectors were higher, with energy and tech sectors gaining the most. Facebook surged 12.2 percent to $106.23 after the world's biggest social network reported a 52 percent jump in revenue. Amazon, which reports after the bell, was up 5.5 percent at $615.28. The two stocks gave the biggest boost to the Nasdaq. PayPal, which was spun-off from eBay last year, was up 7.3 percent at $33.90 and Under Armour was up 18.4 percent at $81.26 after revenue at both companies beat estimates.
