Cramer's 'Mad Money' Recap: Are You Cut Out to Own Stock?

You don't have to have nerves of steel to play the game, he said. But investors do need to have some nerve. The issues he heard about on vacation will always be there, and the rumors won't be scared off by evidence or common sense.

"There have always been worries in the market. There have always been what I regard to be professional wet-blanket people," Cramer said. "They're very, very persuasive. You know what they're about? They're about losing money."

Unfortunately, positive market predictions don't sell papers -- but they do make money, Cramer said. "And Cramer only cares about making money."

Cramer said that he sees bull markets all over, including in agriculture, infrastructure, machinery, minerals and mining, autos and aerospace. Plus, he said, you need to be in tech, because "this is the season to be tech jolly."

"This is a great market," Cramer said. "But if you can't listen to the endless stream of negativity coming from the press without getting scared, maybe this bull market isn't for you."

In response to a caller, Cramer said that Morgan Stanley(MS) "is good, but it's had a nice run." He called the whole group is cheap, including Goldman Sachs(GS), which he owns for his Action Alerts PLUS charitable trust. And he's just now discovering Merrill Lynch(MER), which is "way down."
