Cramer's 'Mad Money' Recap: BASF's Good Chemistry

If people have made big wins, they should take some profits and play with the house's money, he urged.

In last week's Sell Block, Cramer said he warned people against staying in Blackstone Group (BX Quote) and hopes people listened.

However, horseman Google (GOOG Quote), which Cramer recommended last week, missed its quarter and now the stock is down.

"This was a bad quarter from Google," he said. "Maybe I became a hog on Google."

Also, Cramer said he "screwed up" on his "Game Plan" last week. First of all, anyone who bought his recommended stocks Monday morning wasn't using the game plan correctly, Cramer said.

"Please don't buy the first trading day the week after I recommend a stock," he said. "You have to wait for weakness" -- or in some cases -- "take a pass." If a stock opens up strong, take a pass, Cramer stressed.

Second, in the case of Johnson Controls (JCI Quote), viewers should have set a limit, and if they were unable to purchase the stock at or below their price, they should have also taken a pass, he said.

"That's what you have to do," Cramer said. Don't get jumpy buying stocks.

Cramer said he blew it on Johnson Controls. The stock didn't blow away its quarter, Cramer said, but it's still an "anointed" stock and should start going up after this so-called disappointment.
