US markets mixed, paring the worst of the early session losses following the resignation of the head of President Trump's National Economic Council, Gary Cohen - Dow down -83-points or -0.33%, having been down as much as 350-points in late-morning trade that saw the index erase year-to-date gains. The broader S&P500 slipped -0.05%, with Information Technology (up +0.55%), Real Estate (+0.52%) and Healthcare (+0.50%) the leading sectors, while Consumer Staples (down -0.93%) and Energy (-0.83%) brought up the rear. It was a solid effort for the index after S&P500 futures were down over >1% at one point during Asian trade yesterday. The technology-centric NASDAQ added +0.33%. White House press secretary Sarah Huckabee Sanders said President Donald Trump will sign a proclamation to enact new tariffs on steel and aluminum this week, with “potential carve-outs” for Mexico, Canada and possibly other countries.
