wmc is a special divi that does nothing - its 70 to 80 cents divi quarterly
conerstone is a fraud - plain and simple - its hard at times to short these cef's when they fraud like control the float - they keep the stock up as they transfer ownership from insiders to the public.
cefs are amazing - they are legalized ponzi schems (some of them) such that as long as they disclose they are returning capital they can do so and so people just see the yield and have no clue.
dnp is like this - get short and the shares get bought in quikcly
wmc is nothing like those but it is overvalued on a p/b basis and thats why you saw it go nowhere recently as the sector ran up.
