New Rules

In all of Cramer’s years on Wall Street, he’s learned a thing or two. When it comes to investing, he says, the most important thing to remember is that you have to play by the rules. So he’s gone and set up a few rules of his own – rules that cannot be bent or broken, he says, because nearly every time he’s broken one of these rules he’s lost money. The rules are there for a reason: they keep you disciplined and keep you away from making mistakes. Read on for five of Cramer's most important rules. Check out Cramer’s latest book for all 20 of them.
