[NEW YORK] US stocks snapped a five-day losing streak Thursday, rising despite worries about next week's British vote on whether to leave the European Union.
But sentiment remained jittery due to polls showing a tight vote in Britain on June 23.
"We're far from having priced in a worst-case scenario yet," Art Hogan, chief market strategist at Wunderlich Securities, said of the Brexit vote.
Wall Street stocks appeared headed for another day of losses, but began turning higher around midday. Mr Hogan said a bounce was inevitable after five straight falls, and did not reflect improved investor confidence.
