This President loves tweeting about the stock market. 

President Trump took to his favorite soapbox on Saturday -- Twitter (TWTR - Get Report) -- to point out yet again the stock market is doing well under his watch. He may want to check his math though, or be more specific. Since the day after his election, the S&P 500 has gained about 14.2%. The Dow Jones Industrial Average has risen about 19.6%, while the Nasdaq has tacked on 13.5%.

U.S. Stock Market up almost 20% since Election!

Trump's latest stock market tweet joins his many other stock market references. 

"The stock market is the highest it's ever been," Trump told The New York Times in an interview earlier in July. "It's up almost 20% since I took office."

He also bragged about stock market gains when he delivered remarks to a joint session of Congress in February, as well as during the only solo press conference of his presidency.

And the president is right: Wall Street has largely welcomed his presidency.

Stocks have added about $3.2 trillion since Election Day, as measured by the Wilshire 5000, which tracks all of the stocks actively traded in the United States.

"If we would've said that almost $4 trillion in the stock markets has been created [on November 8], everybody would have laughed at us. They would've said, 'Oh, that's ridiculous.' But that's what -- that's what it is," Trump said at a June 12 Cabinet meeting, rounding up by about $800 billion. 

"We've picked up in market value almost $4 trillion since November 8, which was the election," said in a speech delivered in Poland, rounding up again. "$4 trillion -- it's a lot of money. Personally, I picked up nothing, but that's all right." 

Trump has referenced the stock market dozens of times since his January 20 inauguration, according to database Factba.se. He has now tweeted the phrase "stock market" nine times as president, per the Trump Twitter Archive. On July 15, he mentioned it in three separate tweets.

Trump appears to specifically like tweeting about the Dow, which hit 20,000 five days after his inauguration. He celebrated the milestone with a tweet from the official @POTUS account and has touted the index on his personal account as well.

"Great optimism for future of U.S. business, AND JOBS, with the DOW having an 11th straight record close. Big tax & regulation cuts coming," he tweeted on February 25.

"Dow hit a new intraday all-time high! I wonder whether or not the Fake News Media will so report?" he tweeted on July 3. TheStreet did.
