Wall Street lower at the open after post-election rally

Wall Street opened lower on Wednesday - a day after the Dow closed higher for the seventh day in a row following Donald Trump's election win - as investors brace for higher interest rates. Trump's plans to cut taxes and raise infrastructure spending would boost economic activity, while his proposal to impose tariffs on cheap imports would likely drive inflation higher. The Fed will hike rates in December barring any major shocks, policymaker James Bullard said.
