CNBC's Jim Cramer on Tuesday warned investors that stock prices could be on a downward trend over a short period of time.

"I want to buy these stocks, but only into weakness. However, keep in mind that we've run a great deal, so you have to be prepared for an exogenous event that causes a pullback that will give you opportunities to buy at lower, less-expensive levels," the "Mad Money" host said.
