“We think we can take the banks to the bank,” Craig Johnson, senior technical analyst at Piper Jaffray, said on CNBC. “We think this pullback is a great opportunity. … These are things we should be stepping up to and buying today.”

Looking ahead, the financial sector has an improved outlook as housing and auto sales strengthen, which could add to greater loans and more underwriting fees for banks, Jaffray added. [Ahead of Earnings, Investors Pour Into Bank ETFs]
