Wells Fargo has been the strongest earnings performer among the "big four," with its return on average assets (ROA) ranging from 1.40% to 1.54% over the past five quarters, while its return on average tangible common equity (ROTCE) has ranged from 16.27% to 16.99%, according to Thomson Reuters Bank Insight.

JPMorgan Chase runs second, with ROA ranging from 0.88% to 1.12% over the past five quarters, with ROTCE ranging from 14.24% to 16.82%.

Citigroup's ROA over the past five quarters has ranged from 0.10% to 0.88% and its ROTCE has ranged from 1.22% to 10.19% over the past five quarters.

Bank of America has ranked last among the big four over the past four quarters, with ROA ranging from 0.6% to 0.73%, while its ROTCE has ranged from 0.85% to 10.16%.

But as investors look ahead, they see that Bank of America's consensus 2015 EPS estimate of $1.62% is 76% higher than the consensus 2013 EPS estimate of 92 cents. The other "big four" members don't come anywhere close to that level of expected earnings improvement.
