He said that's a recipe for complacency, which is always dangerous. Cramer said he likes markets that rally off of worry and fear, adding those are the ones with real power. "I do not like markets that rally off of euphoria and good feelings," he continued.Cramer explained that just two weeks ago the markets were preparing for the end of the world, the collapse of the European banking system and the collapse of a few European countries as well. But in just two short weeks, all of the news has reversed and the markets have regained lost ground. The markets are now assuming that there will be no bank collapses, said Cramer, along with no more sovereign debt issues. He said there's an assumption that banks are using low rates to recapitalize and all of our economies will just start humming along without worry. And it's for all of those reasons that Cramer said he cannot lower is threat assessment of DEFCON 3 for the markets. Cramer said he can't' recommend investors buy into a market where everything is set up to go right, because it never does. "Wait for a break before buying," he told viewers, "and if you haven't sold already, it's time to trim." He said even the red-het retails and cyclicals and oil stocks should be trimmed into the rally. "Stay cautious," Cramer told viewers, "a better time to enter now awaits us."
