First I doubt there is much interest here on the technicalities so I am not surprised about the lack of answers. For the others reading see;
Post-modern portfolio theory - Wikipedia, the free encyclopedia on the topic.
Personally I find the technical aspects overblown but since you are writting a professional paper you may see that differently, my argument against picking the topic is that I feel that such topic has been extensively visited already. (
http://www.actuaries.org/AFIR/colloq...guson_Rom.pdf; http://www.fcva.net/Documents%20and%...%20Theory.pdf: Post-Modern Portfolio Theory Comes of Age: The Journal of Investing to just refer to a few older articles). With CIMA and others adding it to the general curriculum (
CIMA Adds Post-Modern Portfolio Theory To Curriculum) it is part of the general analyst exam for certification; in that situation there is plenty of literature, so whatever you do will be a repeat in one or the other facett. If you look at the paper at
http://www.isectors.com/pdf/Practical_App_PMPT.pdf most is already said.
In such circumstances I believe the work on such a paper will not be very satisfying, but hey its your choice and if you want to do something which does not stand to far out (I remember the users of portfolio analysts are general a conservative bunch who do not like rocked boats) you may be right and I may be wrong.
