Cramer is absolutely shocked by the mistakes Wall Street pros are making right now. He doesn't want you to make them too.
"It's plain stupid to trade off headlines before the full story is out," said the Mad Money host.
Seems pretty simple – yet Cramer said it happened twice on Wednesday and in both instances, investors lost money.
In this circumstance pros sold Federal Express on headlines that read 'FedEx Profits Plummet' and 'People in No Rush to Send Packages.' "As money manager pored over the release and saw the headlines they just dumped the stock," Cramer said.
Largely, sellers were spooked by new information which showed that FedEx was cutting its capacity between the United States and Asia.
"Then, came the earnings call and FedEx painted a very different picture," Cramer said. "They were the most bullish that I have heard them be in a very long time."
Ultimately, FedEx forecast earnings growth of 7 percent to 13 percent and said daily volume grew 10 percent in the fourth quarter driven by market share gains and growth in e-commerce.
"As you might imagine, after the call, the stock took off," Cramer said, trading well over 2% higher. Money managers who sold the headlines were crying in their coffee by mid-morning.
