It was going up on a rebound, the way the economy always does. The economy is a charging bull that stops for water breaks. The fact that the water break happened under 0bama has nothing to do with him, nor is the bull acceleration to DJIA 18k. DJIA was 18k in 2014, 2015 and 2016. The bull was running back and forth. 
  
 Trump's election just said to the bull 'go forward' and bam, DJIA 26k in 1 year.
