Wall Street and the US dollar gained overnight as investors positioned themselves ahead of next week's Federal Reserve meeting.
The greenback drew support from Citigroup which called the US currency "attractive". The Bloomberg Dollar Spot Index, which tracks the currency versus 10 counterparts, rose 0.3 percent to 1,224.24 as of 1.20pm in New York.
Wall Street also moved higher, following three days of declines. In 1.25pm trading in New York, the Dow Jones Industrial Average advanced 0.7 percent. In 1.10pm trading, the Standard & Poor's 500 Index gained 0.4 percent, while the Nasdaq Composite Index added 0.6 percent.
Gains in shares of Chevron and those of Boeing, last trading 1.9 percent and 1.6 percent higher respectively, helped propel the Dow higher.
"There is some amount of bargain hunting too as investors are price sensitive and we're going to see some sloppy trading today, because there is no major economic data or news," Kim Forrest, senior equity research analyst, Fort Pitt Capital Group in Pittsburgh, told Reuters.
