Wells Fargo may be one of the only banks to satisfy Wall Street this earnings season, says Paul Miller, FBR Capital Markets managing director of financial institutions research.
Financials, which finished as the third worst performing group on Thursday, will have trouble delivering the goods to investors, especially if 10-year treasury yields fall below 2.5 percent, he said.
"I think the banks continue to sell off. There's a lot of good news factored in these banks, mainly further growth down the road. The banks need a higher yield curve," said Miller on CNBC's "Fast Money." "I think rates are going to stay lower than people think."
