There is little doubt that the Market has responded to the Trump Economic Agenda,

In President Trump’s First Two-and-a-Half Years He’s Already Outperformed Every President in US Stock Market History

Editor:  What has happened to the Stock Market economy beginning 24 hours after Trump was sworn in as President of the United States,  could have happened as early as 2011 or 2012.  Market pressure for a substantial recovery was in place since that time.  But it required a meaningful reduction in the corporate tax rate and a revision (if not a reduction) in the regulatory policies of the federal government.  

In a debate with Hillary in 2008,  Barack went on record refusing to establish a coorporate tax cut,  in spite of admitting that such a policy would stimulate a financial/jobs recovery.  His reason for such a refusal was profoundly silly:  "Such a cut in taxes would not be fair,"  he argued,  "because the middle class and the poor would not receive the same tax break." 

As a result,  his economy for the entire eight years of his time as chief financial officer,  never averaged more than 2% GDP annually, and,  in fact, suffered a 1.8% GDP average for his 8 year term.   

With Trump's swearing in,  the Market took an 800 point dive but reversed itself, all before the first day had ended and has been on a remarkable upswing since that time.    

The hope of regulatory reduction coupled with a corporate tax cut, was enough to drive the beginnings of the Upswing.  Of course,  in time,  hope was replaced with reality and the Market has been on record pace ever since.
