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. U.S. stock futures fell and European shares opened lower, although they recovered some losses in early London trading after the initial overnight move. 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.
