All too often you hear 'weakness is an opportunity' said Cramer. Of course, that's not always the case. How about now?
Back in the days when Cramer worked on the trading desk, he and his colleagues often heard analysts pound the table that every pullback was a buying opportunity.
But they knew that wasn't the case. They would sometimes say "here comes the BO!" In other words, in that circumstance the buying opportunity stunk.
There are plenty of investors in the market who are bearish and currently subscribe to the BO philosophy. "There are many who want to fight this tape," Cramer explained. "They think that stocks are overvalued because they keep getting revised upward on little news."
