If you're not buying stocks after Wednesday's market selloff, you'll be sorry, Stifel Financial Chairman and CEO Ronald Kruszewski said Wednesday.
The Dow Jones industrial average dropped 238 points and the Russell 2000 entered correction territory, down 10 percent from its July high, making for the stock market's worst start to October since 2011.
"Look, I think it's a normal correction in a market," he said. "We haven't had a 10 percent correction in the S&P in over 1,000 days."
On CNBC's "Fast Money," Kruszewski said that the longer-term trend was up despite a down day.
