still less than one year into Trump's presidency -- who gets credit for the stock market uptick?

While Sam is correct that Wall St. hopes the party will continue, with Trump pursuing “public be damned” policies, the perspective reflected in the above excerpt is rather blindered.

During the Obama Administration, the major averages of the U.S. stock market more than Tripled. That’s Tripled with a T. The Nasdaq Composite Index more than Quadrupled. That’s Quadrupled with a Q. In and of themselves, these astounding facts don’t make the Obama epoch unique. There were a few other strong booms: during the Clinton years, during the Roaring Twenties, and during the mid-1930’s recovery from the Crash. However the prior booms were accompanied by share prices rising in Europe and around the world. During the Obama Boom, other world markets remained in the doldrums — a special American exceptionalism had indeed returned. Employment has risen sharply. The share of the U.S. economy accruing as corporate profits is now at a nearly unprecedented level. Billionaires have seen their worths climb dramatically.

In the context of reality, “Obama['s] regulations … held back growth in [share prices]” and “depressed confidence” is a peculiarly partisan synopsis.
