Cramer tells everyone to buy, everyone buys. Price goes up, then smart people cash out in the profit taking. It doesn't matter what the recommendation is after that buy. Cramer can tell you to sit in a dark closet and fart for the rest of the week. He's successfully driven the price up on a very short term basis, and those that have caught on make easy money.

This is a well known effect.

I like the assertiveness of this command to stop downvoting compared to the often passive-aggressive or hurt pleas.

you can literally watch a tick-by-tick chart of a Stock/ETF that is talked about by any of the CNBC talking heads during market hours and watch this occur in real time.
