Wall Street weakened from record highs as investors focused on US President Donald Trump's address to Congress later in the day to assess if bets on his broad policy promises are justified.
"While markets no doubt appear to like what they are hearing, the president now needs to deliver," Michael Hewson, chief market analyst at CMC Markets in London, wrote in a note, Bloomberg reported. "If he fails to do so, we could well see a swift market reaction."
In 1.09pm trading in New York, the Dow Jones Industrial Average fell 0.1 per cent, while the Nasdaq Composite Index dropped 0.6 percent. In 12.54pm trading, the Standard & Poor's 500 Index declined 0.3 per cent.
The US dollar also moved lower, while Treasuries gained, pushing the yield on the 10-year benchmark note one basis point lower to 2.35 per cent.
"What we're looking for tonight is just more meat on those bones," Mark Spellman, portfolio manager at Alpine Funds in Purchase, New York, told Reuters. "We've gotten these generalities and we're trying to figure out how things are going to be constructed."
