● This paper reviews several aspects of the asset allocation debate and offers observations to reshape or provide a fresh perspective. ● The first area of exploration is the debate over the well-known 1986 study by Brinson, Hood, and Beebower, in which they contend that the changes in portfolio return variations over time can be explained by static index implementation of asset allocation versu...
