On a more negative note, Zions Bancorporation's management said that the company's loan growth depended in part on aggressive price competition, which Miller said "does not bode well for the company's [net interest margin], which is already under pressure due to the general low rate environment, and we expect estimates to come down as a result.
Zions reported a second-quarter net interest margin -- the difference between a bank's average yield on loans and investment securities and its average cost for deposits and borrowings -- of 3.62%, declining from 3.73% the previous quarter, but unchanged from a year earlier.
Miller called Zions "an asset-sensitive bank that thrives in a rising rate environment," and said that "with rates likely to remain flat for the foreseeable future, we look to remain on the sidelines with regard to shares.
The analyst estimates that Zions Bancorporation will earn 98 cents a share for all of 2012, followed by 2013 EPS of $1.85.
