New York: Alarmed investors sent the Dow plunging more than 650 points in a shortened Christmas Eve trading session on Monday. Markets plunged after the Trump administration sent out confusing signals about markets and the economy.
The S&P 500 fell 2.7% and the Nasdaq was off 2.2%.
Stocks initially fell on Monday following a statement from Treasury Secretary Steven Mnuchin that he had checked on the health of the country’s largest banks.
The market recovered late morning, but then plunged even lower after President Donald Trump tweeted: “The only problem our economy has is the Fed.” Investors are concerned that Trump may fire Federal Reserve Chairman Jerome Powell.
