S&P looks set to snap seven-day losing streak

The S&P 500 looked set to snap a seven-day losing streak on Thursday, but a fall in Facebook's shares dragged down Nasdaq futures. Tension in global markets rattled by U.S. election nerves eased after a UK court ruling that parliament must approve a government decision to trigger Brexit. Facebook fell 5 percent to $120.87 in premarket trading, a day after the social media giant warned that revenue growth would slow this quarter.
