Annaly Capital Management If you're looking for a high-yield dividend stock to trust for income generation over the long run that's been absolutely clobbered in recent years, then I'd point you in the direction of mortgage real estate investment trust, or mREIT, Annaly Capital Management. Mortgage REITs tend to be at their best when interest rates are falling or at their lows since it widens their net interest margin, allowing them to borrow at low rates and re-lend at higher rates. When rates are rising or expected to rise, the opposite can be true.
