Impossible to tell if there is a discount or not since too many variables are in flux. However, after a huge sell-off on high volume the stock did turn on Ben's mumblings. If one bought when they should have @$21.50 or so, then all they can do is to set a stop-loss and wait to see. Only the market can tell you if there is a discount or no - not a poster on Seeking Alpha or anywhere else.
It will be interesting to see what happens. AGNC went from wonder child , to over reaction, and now is under valued with huge fed fears on the horizon. Its a real tug of war. Its gut check time. Those who chose right will probably make some good money ( short or long ). The flock will sit back and wait for the herd to go in one direction. Of course, at that point, the opportunity to make money will be gone. Time to purchase some pop corn.
