As the votes started to swing in Donald Trump's favor overnight, Dow futures made some pretty stunning moves — at one point plummeting more than 800 points.
The plunge suggested markets had not expected a Trump victory and would be in for a wild ride Wednesday as investors digested the results of the U.S. elections.
Since then, futures narrowed their losses and were down about 286 points, or 1.6 percent.
Still, volatile trading is not unusual the day after an election. While the 2012 presidential race was arguably much less tumultuous, the markets still made some big moves.
