Buy more NLY or AGNC now

Along with hard selling of mREITs including NLY and AGNC in the past week or so, the discount to their book value for both NLY and AGNC is around 9-10%. It is a clear over-reaction, which creates a great buying opportunity if you want to establish a postion or add more. The more it is sold, the less risk it will have. You just need the gut and patience to do so. Simply buying NLY or AGNC will give you a yield of 12% or 18% respectively as it stands now. And a good chance of great capital returns in the months ahead. If you really want to have safety, then using cover call to generate more income to protect your capital. If you go deep enough into the money when writing a call, you may almost completely protect your capital while enjoying the high yield. I know it is very technical but for those who understand options, this is some food for thought.
