Wall Street moved higher, while the US dollar slid, as investors await the outcome of the Federal Reserve policy meeting on Wednesday to gauge the timing of the next interest rate increase.
While few expect Federal Open Market Committee to announce a rate hike this week, most bet they will do so later this calendar year.
"Fears about the Fed increase and then dissipate, and all you can do is try to follow that news flow," lan Higgins, chief investment officer at Coutts & Co in London, told Bloomberg. "The Fed is very aware of what the market is looking for and hopefully we'll get no policy shock."
In 3.10pm trading in New York, the Dow Jones Industrial Average rose 0.2 per cent, while the Nasdaq Composite Index inched 0.01 per cent higher. In 2.55pm trading, the Standard & Poor's 500 Index gained 0.3 per cent.
"The market has been all over the place. It's been driven by the threat of higher interest rates," Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, told Reuters. "Most people feel the most unloved bull market in recent memory will be cut off at the knees by higher interest rates and the Fed is certainly threatening that in the near term."
