Wall Street was mixed overnight as investors found value in some beaten-down stocks including biotech shares, even as concern lingered about the global economic outlook.
In New York trading at about 1.30pm, the Dow Jones industrial average rose 0.3 percent, while the Standard & Poor's 500 Index eked out a 0.08 percent advance. The Nasdaq Composite Index slipped 0.1 percent.
Gains in shares of 3M and those of Johnson & Johnson, last up 1.7 percent and 1.6 percent respectively, led the Dow higher.
"Investors are still very nervous on the global markets," Paul Nolte, portfolio manager at Kingsview Asset Management in Chicago, told Reuters. "I think it's buying of what has done poorly and selling of what has done well in the last two-three days - a little bit of bargain hunting, a little bit of taking advantage."
Even so, Goldman Sachs' chief US equity strategist David Kostin downgraded his year-end price target for the S&P 500 to 2,000, from 2,100, citing "a slower pace of economic activity in the US and China and a lower oil price than we had been previously assuming."
US consumers proved more upbeat than expected. The Conference Board's consumer confidence index climbed to 103.0 in September, from a downwardly revised 101.3 in August.
