Market Moving Insight and Analysis. Join Jim Kramer, David Faber, and me, Carl Kintania, on the opening bell hour of CNBC Squawk on the Street.

This is C&BC. Good Monday morning. Welcome to Squawk on the street. Market Sell off.

I'm Carl Kintania with Jim Kramer, David Faber, the New York Stock Exchange. The Dow is set for its worst day in about four months, as concerns about the coronavirus do get worse.
