S&P 500 E-mini futures turn negative as votes counted in UK referendum

SAN FRANCISCO, June 23 (Reuters) - S&P 500 futures turned negative on Thursday after Newcastle, seen as a safe "remain" district, reported only a marginal win in Britain's referendum over whether to stay in the European Union.

S&P 500 E-mini futures were down 0.4 percent, giving up earlier gains. Earlier on Thursday, U.S (Other OTC: UBGXF - news) . stocks rallied as Wall Street bet strongly that Britons would vote to remain part of the European Union, potentially avoiding a hit to European trade and its consequences to global economic growth.
