In the following video, Motley Fool financials analysts Matt Koppenheffer and David Hanson take a look at a speech given by the Fed's Janet Yellen, in which she discusses the Fed's plan to be highly communicative and transparent about how much longer its accomodative quantitative easing policy is going to continue. Matt and David tell us that this can only mean good things both for mortgage REITs like Annaly Capital (NLY -0.18%) and American Capital Agency (AGNC -0.03%), and for investors in these companies, as it will leave everyone better informed about what the Fed is up to and when interest rates are going back up, without needing to rely on rumor or prognostication.
