Business insider reports something so terrible that it should be causing Trump to shake in his golden boots:

‘The US stock market’s horrible year looks set for a particularly nasty ending, with both the S&P 500 and the Dow Jones Industrial Average on track for their worst ends to the year since 1931.

The S&P 500 is headed down 7.8% in December. If it were to close at that level or lower, it would mark the index’s worst performance in the year’s final month since 1931, when it closed with a plunge of about 15%. The same is true of the Dow, which has dropped more than 7% since December 1. (The Dow plummeted 17% in December 1931.)

Those losses would eclipse the most recent major slump, in 2002, when both the S&P and the Dow dropped about 6% in December.’
