Stock of the day: Zions Bancorp (NASDAQ:ZION)

Two regional US retail banks announce results on Monday – Zions Bancorp (NASDAQ:ZION) and Keycorp (NYSE:KEY). ZION has been popular with short sellers for some time and remains highly borrowed with 12% of the company on loan. 1.5% of Keycorp is the figure for KEY. Both firms show the same pattern of positive investor sentiment over the past two weeks – represented by falling shorts and rising institutional ownership. However, in the last few days this trend has started to reverse. There is an anticipation from some that the recent price rally in both may run out of steam if the results are only modestly positive, according to Diamond Hill Capital Management on Reuters.
