Banc One's already lackluster stock has weakened again, as investors fret that the superregional is an unlikely buyer of other major banks this year.

On Monday, Bane One's shares were down 75 cents to $32.35 at the close, a drop in value of 8.2% from the stock's most recent high on April 15 and 24% below its 52-week high of $42.25.
