Wall Street pared earlier gains overnight as oil plumbed fresh lows, while other commodities also fell, as investors tried to gauge China's efforts to stabilise its stock market and currency.
In 12.54pm trading in New York, the Dow Jones Industrial Average fell 0.1 per cent. The Nasdaq Composite Index, however, rose 0.2 per cent. In 12.39pm trading, the Standard & Poor's 500 Index slid 0.2 per cent, after earlier rising as much as 1.2 per cent.
"This is a market that's been selling off very hard and is probably short-term oversold," Alan Gayle, senior strategist for Atlanta-based Ridgeworth Investments, told Bloomberg. "Trying to read the day-to-day implications from Chinese policy moves is exceptionally challenging."
Oil weakened. Benchmark Brent crude touched US$30.43 per barrel, the lowest since April 2004, while US West Texas Intermediate crude slid as low as US$30.10, the lowest since December 2003.
"The momentum is too strong to the bearish side, even if fundamentally nothing has changed," Dominick Chirichella, a senior partner at Energy Management Institute, told Reuters.
