The Federal Open Market Committee starts a two-day meeting on Tuesday. It will release its latest policy statement at the end of the meeting on Wednesday in the US, followed by a news conference hosted by Bernanke.
"Bernanke's first goal is to get people to understand that there will be no tightening in the rate of purchases," said Jim McDonald, chief investment strategist at Chicago-based Northern Trust Global Investments, told Reuters.
"And since there are acceptable signs of growth in the economy, investors with a medium or longer-term horizon are happy to be buying in this environment."
