Wall Street rose overnight, as did oil, after China's central bank lowered its reserve requirement ratio in an effort to stoke economic growth.
It was the fifth time in a year that China's central bank cut the amount of cash that banks must hold as reserves.
Wall Street moved higher. In 12.38pm New York trading, the Dow Jones Industrial Average rose 0.3 percent, while the Nasdaq Composite Index gained 0.5 percent. In 12.23pm trading, the Standard & Poor's 500 Index advanced 0.4 percent.
Oil also gained, bolstered by Saudi Arabia's promise to cooperate with other producers to help stabilise prices. The Saudi cabinet said in a statement it "will always remain in contact with all main producers in an attempt to limit volatility and it welcomes any cooperative action," according to Reuters.
Gains in shares of Caterpillar and those of DuPont, last up 1.9 percent and 1 percent respectively, led the Dow higher.
