RealMoney Radio Recap: Getting a Q&A Clue

Answering his next question, Cramer said the changes in technology have not changed the market significantly, other than allowing people to buy and sell much more cheaply and read a lot more about companies. TheStreet.com, which Cramer founded, allows you to read this information, he said.

When a mailer asked what the most satisfying part of market is, he said the market is not a game of culture or helping people, but of making money.

"It's not satisfying when you lose a lot, and it is when you make a lot," he said. "It's a bad day when you lose money and a good day when you make some."

IPO Odyssey

Initial public offerings can be good or bad, Cramer told a caller.

The best IPOs tend to be companies that are early on in a new business cycle, he said, adding that the dogs come in by the time every one has come public.

Cramer said he was intrigued when MasterCard(MA Quote) became public. Nobody thought much of this company, but it has become a big winner, he said.

"I look for out-of-the-way stuff that could work," he said. "When I look at an IPO, I don't necessarily want the hottest one."

When he was a hedge fund manger, he said he liked the ones that went up over time, like iRobot (IRBT Quote).

Cramer said he tends to like a company when it "gingerly" becomes public, adding that a lot of banks are like this.
