Wall Street rally pauses near record highs

U.S. stocks were little changed on Tuesday after key indexes hit record highs as oil prices turned lower and investors grappled with policy uncertainty under President Donald Trump. The Dow Jones Industrial Average and the Nasdaq Composite hit all-time highs just after the market opened, with the S&P 500 coming just shy of yet another record high. Energy was the worst-performing S&P sector, falling 1.3 percent.
