The preferred shares for NYMT are listed as NYMTP . They paid 7.25% ( $1.81 annually ) when issued at $25 in May, 2013. Currently selling below par, the return is around 8.4% . While the common pays twice as much as the preferred, the latter provides a higher degree of safety. I own both the common and the preferred.
For what it is worth, (and I hope I'm not too "nit-picky"), the dividend is .4844 x 4 = 1.9475, 1.9375/20.54 = 9.4328% which is a pretty good yield for a preferred. The coupon rate is 7.75%. I bought some today.
It depends on what stock screener you are using. For Yahoo, enter in the letters of the company issuing the preferred shares followed by a dash and then a "P" along with the letter corresponding with the series of preferred you are looking for: (such as NYMT-PA) for New York Mortgage Trust Preferred Series A
