Catou:
I suspect the bounce in price of many of these rate reset preferreds is not because of anticipation that their dividend payments will rise but rather that the dividend cut to come won't be as deep as it might have looked to be just a few short months ago.  
Again at least to me, the far superior investment is one where the dividend rises every year and that dividend paid is not subject to fluctuation (both up and down) based on some unknowable, extraneous factor like the future interest rate on a five-year government of Canada bond. 
Clearly I am looking at this from an inestor's point of view, not as a short-term trader might.
And by the way, sometimes prices rise on dividend-growth companies' stocks in anticipation of their annual dividend increase announcements. It does happen.
