"This Verizon ( VZ) quarter was really strong for wireless, really strong for FiOS," said Jim Cramer on Monday's "Stop Trading!" segment on CNBC. "It's the beginning of what I think is going to be a series of upgrades."Cramer said that Verizon's earnings-report pattern is that "everyone pooh-poohs Verizon's number instantly, and then they take a second look." He called the stock a "very strong buy." Whirlpool ( WHR) also reported a "very good quarter," he said, even though "Whirlpool should be losing money hand over fist in this type of economy." He said that Whirlpool's quarter and the reaction to the stock are "absolutely a sign that things are bottoming." Cramer told viewers to check out the Federal Reserve Bank of Dallas and the Texas Manufacturing Outlook Survey. "April turned up nicely, so nicely that they're saying it might have turned back a lot of the downturn from September," Cramer said.
