Both the Dow Jones Industrial Average and the Nasdaq have reversed course after a week of losses. The Dow was up 570.50 points to 25,979.86 and the Nasdaq was up 112.96 to 8680.33 near midday trading. The two major bellwethers of investor sentiment had a rough week last week as the spread of the novel coronavirus, COVID-19, and the response from governments that it engendered cut into supply chains and corporate earnings.
