If I could say the bottom, I would be very very rich by now. But one thing to keep in mind ( in all this excitement about bounce back ) is that MANAGEMENT of all MReits ( especially AGNC ) is buying back their stock ( thus supporting the stock price ) when they are selling at a 10% or more discount to BV. The big question is - HOW LONG can they KEEP DOING it ? It takes a small matter of a thing called CASH to do that after all !
So I would try to NOT get TOO EXCITED about these bounce backs. I would rather keep a close eye on the earnings and interest rates and MBS prices - just my 2 cents.
