Analysis and Applications of Alternative Portfolio Optimization Approaches

Background
Over 70 years ago Harry Markowitz launched finance into a new era by inventing modern portfolio theory [1].

Markowitz approach is to choose the right portfolio as the one that maximizes expected returns and controls the risk (modelled as the variance of the portfolio).

One of the (possibly undesired) consequences of the above approach is that the resulting allocation distributes large parts of the risk to the small modes of, the correlation matrix of returns of the different securities.

There are many alternative approaches that lead to portfolios that are optimal in a different sense [2,3,4] and that redistribute risk differently.

Their respective derivations are typically very different and yet the resulting allocations can often be brought into similar forms.

Objective(s)
(a) Unify the theoretical foundations that lead to the different portfolio optimization strategies.

Exemplary directions:

Are there some shared first principles that can unify the different approaches?
The following approaches are typically derived from different principles and yet ( are expected returns):

Markowitz approach [1]

Max. entropy approach [2] 0
Agnostic Risk Parity approach [3] 1
What are the practical limitations and possible/necessary extensions in realistic settings?
How does the structure of impact the results?
How should the methods be adapted in a dynamic setting under cost constraints?
