Wall Street dips on Trump protectionism, Qualcomm drag

U.S. stocks edged lower on Monday as early moves by President Donald Trump highlighting a protectionist stance on trade gave investors cause to rethink the post-election rally. In his latest executive order, Trump signed to formally withdraw the United States from the 12-nation Trans-Pacific partnership trade deal. Trump has also vowed to renegotiate the North American Free Trade Agreement (NAFTA) with leaders of Canada and Mexico.
