All of the other MREITS (except CYS about which there is an interesting Seeking Alpha article) have already declared their dividends. Until ANH declares, many would rather buy a known quantity in a quarter where some are lowering the dividend compared to Q2 (CMO and AGNC). If ANH declares at least .32, it should get a nice pop IMHO compared to the other MREITS. .30 is probably worst case and at 7.86 (without even backing out accrued div of about .25) the yield would be 15.3%. All in all this is a good entry point.
For those written on the Oct 7 1/2 calls, it might be worth rolling them out to April for a .10 credit, as I did yesterday for some of my position. It will decrease the chance of being assigned significantly, unless the stock really goes higher. And even if you get called, you have taken out a little more by rolling.
