This paper brings Black–Litterman optimization, exotic betas and varying starting portfolios together into one complete, symbiotic framework.
Agnostic risk parity: taming known and unknown unknowns
This paper offers a new perspective on portfolio allocation, which avoids any explicit optimization and instead takes the point of view of symmetry.
Optimal management of green certificates in the Swedish–Norwegian market
