Note: This is mostly a repeat of a June 2017 post with updated statistics and graph, and one new quote.

There are a number of observers who think the stock market is the key barometer of policy success.  My view is there are many measures of success - and that the economy needs to work well for a majority of the people - not just stock investors.

However, for example, Treasury Secretary Steven Mnuchin was on CNBC on Feb 22, 2017, and was asked if the stock market rally was a vote of confidence in the new administration, he replied: "Absolutely, this is a mark-to-market business, and you see what the market thinks."

And Larry Kudlow wrote in 2007: A Stock Market Vote of Confidence for Bush: "I have long believed that stock markets are the best barometer of the health, wealth and security of a nation. And today's stock market message is an unmistakable vote of confidence for the president."

Note: Kudlow's comments were made a few months before the market started selling off in the Great Recession. For more on Kudlow, see: Larry Kudlow is usually wrong

Update: And from White House chief economic advisor Gary Cohn on December 20, 2017:

"I think there is a lot more momentum in the stock market. ... "The stock market is reflecting the reality of what's going in the business environment today," said Cohn, director of the National Economic Council. "There is going to be a continuation [of the] rally in the equity markets based on real underlying fundamentals of the U.S. economy ... as well as companies having more earnings power because of lower tax rates."

For fun, here is a graph comparing S&P500 returns (ex-dividends) under Presidents Trump and Obama:

Blue is for Mr. Obama, Orange is for Mr. Trump.

At this point, the S&P500 is up 20.2% under Mr. Trump - compared to up 37.4% under Mr. Obama for the same number of market days.
