However, the stock market has surprised many and actually gone up significantly since Trump's victory.
Highlighting the market's performance, the president-elect noted in a tweet on Monday, "The world was gloomy before I won – there was no hope. Now the market is up nearly 10% and Christmas spending is over a trillion dollars!"

Explaining the possible reasons behind the rally, the New York Times noted, "Investors have concluded that at least in the short run, many of Mr. Trump's policies, including increased spending on infrastructure projects, could lead to faster economic growth than was expected."
In regards to Trump's mention of Christmas spending, he didn't provide a source, but according to CNBC, "A Deloitte University Press report in September projected that holiday sales this year will exceed $1 trillion, reflecting a 3.6 percent to 4.0 percent increase..."
As is the case with many Trump's tweets, this one prompted a fierce online debate.
Some questioned how much the president-elect is responsible for these positive trends, with comments like, "He's not even in office yet and he's patting himself on the back for things he has nothing to do with."
On the other side, a commenter defended the tweet, asserting, "actually he can take credit. It's obviously a cause and effect of him being elected that the markets are reaching new records."
