Jim Cramer was stunned by the lack of homework done by investors on Friday, and he hopes that doesn't extend into next week.
Shares of Honeywell dropped sharply after the company indicated that earnings could come in at the low end of its range. Investors forgot that industrials don't trade on earnings, but on organic growth. When taking that into consideration, the company actually guided up on that key metric.
"Just because we have a good run, that doesn't mean we stop doing homework. Don't be a misinformed miscreant. I'm begging you, take a few moments to do some thinking before you take action," the "Mad Money" host said.
There was also a note out from JPMorgan's Matthew Boss that stated a weak quarter could be coming from Nordstrom, as the company warned this is the worst mall environment since 1972.
That was all the signal Cramer needed to be concerned about department stores.
"Beware the department store, or at least the department store stocks ... If Nordstrom is hurting, and its stock fell nearly 9 percent today, they can't be alone," Cramer said.
