Cramer recounted what he used to call his "Bristol-Myers Theorem," derived from Bristol-Myers Squibb ( BMY), a drug company with the most consistent earnings imaginable. He explained that back at his hedge fund, anytime an associate would run in panicking about a negative story, he would always ask, "How does that affect the earnings of Bristol-Myers?" In just about every case, it didn't. That's why Cramer often recommends reliable, consistent earning stocks with great dividends, stocks like Kinder Morgan Energy Partners ( KMP), or Verizon ( VZ), or utilities such as Southern Company ( SO). Cramer said no matter what the negativity of the day, companies like these will allow investors to put those stories into perspective.
