Jim Cramer on markets as stocks plunge and Dow drops more than 800 points

Stocks plunged on Thursday with the Dow dropping more than 800 points as tech shares snapped a 10-day winning streak. Mad Money host Jim Cramer joins 'Closing Bell' to discuss. I'm very skeptical about today's action, he says. When you see stocks that are down 10 percent, that means there are people frantically trying to get rid of these stocks at the bell, says Cramer. It may be time to ring the register, he adds.
