Stocks closed near session lows Thursday as investors digest the Federal Reserve's 0.75% rate hike. The Dow dipped below the key 30,000 mark for the first time since January 2021. While investors were previously optimistic about the Fed's announcement, they're now worried this week's rate hike could mark an overly-aggressive approach and tip the U.S. into a recession. Scott Wren, senior global market strategist at the Wells Fargo Investment Institute, joins Closing Bell to discuss today's close, when the U.S. could enter a recession and how bad it might be, and more.
