Editor's Note: This is a recap of a program that was orginally broadcast on Good Friday, April 14.
When people hear about insider trading, the movie Wall Street usually comes to mind, Jim Cramer said on his "RealMoney" radio show Friday. Insider trading has reared its head once more as analysts from Merrill Lynch ( MER)and Goldman Sachs ( GS) were recently arrested and charged with insider trading and securities fraud. But Cramer said he has no sympathy for them. While the Securities and Exchange Commission used to rely on whistle-blowers for tips, now the SEC process used to catch insider trading has become more sophisticated as they have the ability to track every trade. "They will nail you" if you are caught, he said, adding to remember that in the case you are caught, you are presumed guilty until proved innocent. If you get a tip, look at both sides of what it is, he said. If you get insider information and gain from it, the government will come and confiscate your gains at best and throw you in jail at worst, he said. If everyone knows the tip you're not going to profit from it, he added. "Tips are for waiters, and will cause you to lose money," he said, adding that if people are buying stocks on tips they don't need to listen to Cramer's show because they won't have money to play the game. Zoltek ( ZOLT) has moved from $9 to $21 and now it's time to sell it, Cramer said. Instead, he recommended getting into Chesapeake Energy ( CHK), since he believes natural gas prices are going to rise. In recent Friday trading, Zoltek was at $24.23, while Chesapeake was at $29.35.
