I have been a big fan of Wells Fargo preferred ever since the crisis. Great income instrument. Annaly ... maybe ok but know that these are perpetual instruments and not as liquid , and if trading in retail lots, the bid ask can be really wide. Check the tax implications also
On a different note, "seeking alpha" always keep pitching every income and dividend stock in my inbox every single day. There is not a preferred or high yielding stock that they don't like so take whatever they say with skepticism
As the market rallies and yields on the mainstream fixed income instruments keep falling, and stocks keep getting richer on a forward P/E basis --- you will see a lot of esoteric investments come out of the woodworks because they look "cheap compared to everything else" .
