On Friday, "Mad Money" host Jim Cramer broke down his five rules to help investors make money in any environment.
Rule No. 1:"Don't dig in your heels when you're wrong"
Rule No. 2:"Price matters"
Rule No. 3:"Don't take your cue from an inferior company"
Rule No. 4: "Don't believe the hype"
Not all upside surprises are worth getting excited about, Cramer said. If a company reports quarterly results that show its earnings-per-share are higher than what the average analyst on Wall Street had expected, then all of the headlines will describe it as an upside surprise.
