Stocks sold off and investors quit riskier assets on Friday after U.S. President Donald Trump said he and his wife had tested positive for the coronavirus and would isolate, four weeks before U.S. elections. Shortly before 0500 GMT, Trump said on Twitter that he and his wife had been tested for coronavirus after Hope Hicks, a senior advisor who recently traveled with the president, tested positive. S&P 500 futures — which fell sharply on Trump’s tweet — stabilised somewhat and were down 1.4% at 0931 GMT .
