It might be time to buy the banks, Jim Cramer said on NBC's "Stop Trading!" segment Monday. Cramer isn't sure that all financial stocks are sells right now. " Nat City yields 9%. ... Don't overlook the fundamentals." "My temptation is to say everybody's going to sell," Cramer added. "Maybe you have a tradable rally in the largest stocks in the world, because everyone is going to sell. ... with these stocks where they are right now ... it's probably worth it to take a stand on these." Cramer said things may be "good, not bad," for the financials. He pointed out that with CEO John Stumpf, whom Cramer believes in, Wells Fargo ( WFC) should recover well. Cramer also reaffirmed his support for new Merrill Lynch CEO John Thain, calling him the "man to watch at Merrill." Cramer said he was excited to see that Thain brought back Jeffrey Kronthal, who was ousted from Merrill in 2006 "because he didn't want to do a lot of subprime." "I'm liking Thain and Kronthal," Cramer said. "Dip into banks."
