Wells Fargo & Company (WFC) offers multiple preferred stocks; I favor the Series D (WFC.PR.D) for its yield and risk profile. Series D provides a 6.2% yield, strong dividend coverage (17–20x), and robust equity-to-preferred coverage (9.5x), minimizing default risk. Series D's low coupon and call protection reduce call risk, making it preferable to higher-coupon alternatives with similar yields.
