Jim Cramer says there are two main reasons why bank stocks could be the ones to own in 2017. "I'm valuing the banks for the first time in many years on earnings. Citigroup (C) - Get Citigroup Inc. Report can easily earn $5 a share. Wells Fargo (WFC) - Get Wells Fargo & Company Report and Bank of America (BAC) - Get Bank of America Corp Report have more earnings power as compliance costs go down." Cramer goes on to say that this sector does very well under deregulation and at least three rate hikes this year.
