One of the scare tactics that Donald Trump used in the 2020 presidential campaign was about the stock market. He told investors that the market would fall drastically if Joe Biden was elected, and investors would lose huge amounts of money.
As expected, that turned out to be just another of his thousands of lies.
The market rose sharply in the month after Joe Biden's election, and rose significantly more than it rose after the 2016 election. In fact, the Dow, NASDAQ, and S&P 500 all rose more after Biden's election than after Trump's election.
Investors in the market hate surprises, like the crazy actions by Trump (such as a trade war against China and many of our allies). They see Biden as returning to solid economic principles, and they like the team of economic professionals he has chosen.
