President Trump on Saturday predicted a stock market crash “the likes of which has not been seen before” if he doesn’t win re-election in 2020. “The Trump Economy is setting records, and has a long way up to go,” Trump wrote on Twitter. “However, if anyone but me takes over in 2020 (I know the competition very well), there will be a Market Crash the likes of which has not been seen before! KEEP AMERICA GREAT.” The president’s comments came shortly after he hyped up the upcoming launch of his campaign at a Florida rally on Tuesday. Trump has repeatedly claimed that the success of the U.S. stock market depends on him remaining in the White House, though data from Macrotrends suggests the performance of the Dow Jones Industrial Average has been about average under him compared to its performance under former presidents Barack Obama and Bill Clinton, according to Bloomberg.
