The Nasdaq lost ground sharply on Thursday, dragged down by a slide in technology stocks, as investors poured money into sectors that may benefit from Donald Trump's victory in the U.S. election.
The S&P 500 extended its loses to trade lower, while the Dow hit a record intraday high earlier in the session.
Trump's proposed policies such as tax cuts, higher fiscal spending and simplifying regulation are likely to benefit sectors such as banks and industrials.
But the possibility of Trump slapping punitive tariffs on exports from some countries such as China has unnerved some investors.
"Tech stocks aren't really in the handbook," said Art Hogan, chief market strategist at Wunderlich Securities in New York.
"They aren't really going to benefit from Trump's stimulus spending on infrastructure and are sort of sitting in the middle. They aren't part of the oversold sectors such as banks and health nor are they high dividend paying stocks that getting sold off."
