President Donald Trump is fired up about the recent stock market gains and is promising that more good times are ahead.

Stocks have been on fire as of late, with the Dow Jones Industrial Average gaining nearly 4 percent during a rally that began in mid-August. Though some investors think the jump could be the calm before an autumn storm, Trump took the opportunity for a victory lap in a Thursday morning tweet.

"For all of you that have made a fortune in the markets, or seen your 401k's rise beyond your wildest expectations," he said.

The rally brings the Dow up to a 5.7 percent rise year to date. Markets have shrugged off a series of headwinds including worries about a trade war, higher interest rates and rising valuations that are making parts of the market looking expensive.
