Jim Cramer says to get used to the market having down days, because the Dow didn't get to 19,975 without them, and it won't get to 21,000 without them, either.
"Sell-offs are a natural occurrence, and if they never happened, we wouldn't be fixated on Dow 20,000 because we would be closer to Dow 200,000," the "Mad Money" host said.
The market declined on Thursday, and Cramer explained the reasons why and whether investors need to worry about it.
The first thing Cramer does when he dissects the tape is to figure out what the leadership stocks are. On the downside on Thursday, it was retail, especially Bed Bath & Beyond, which tanked 9 percent after missing projections.
