"Everyone was worried that credit would never improve until unemployment improved," said Jim Cramer on CNBC's "Stop Trading!" segment on Wednesday.We're seeing, however, that that is not the case, he said. "It looks like credit's improving ahead of unemployment," he said. For example, Capital One ( COF) is "not as bad as we thought," Jefferies upgraded American Express ( AXP) to buy, and "we see June doing better" in terms of monthly credit trends. Turning to FedEx ( FDX), Cramer said that people "were so suspicious" of its optimism. "They thought that FedEx had jumped the gun the previous quarter in saying things had bottomed," he said. "Does the stock not tell you that FedEx is spot on?" Cramer said. "This stock should be going down. The transports are struggling and struggling to break out here. I think they do."
