The Dow Jones Industrial Average surged Thursday afternoon after a dramatic morning plunge, concluding another day of extreme volatility in the stock market. The Wall Street Journal reports that after declining all morning, the Dow swung 850 points in the afternoon to close on a relative high. This comes just a day after the Dow gained 1,000 points on Wednesday, marking its largest single-day gain in history. That jump was preceded by the worst-ever Christmas Eve market drop, spurred in part by Donald Trump’s criticism of Federal Reserve Chairman Jerome Powell. JJ Kinahan, the chief market strategist at TD Ameritrade, told the Journal that this volatility is likely here to stay, at least in the near future. “So many things have come together that I’d expect the volatility to continue into the new year,” Kinahan said. “There’s still a lot of answers waiting around earnings [growth], tariffs and a sense of where the economy is at.”
