 | | Modern portfolio theory (MPT) and its mean-variance optimization (MVO) model for asset allocation are Nobel Prize-winning theories of global equilibrium, but are unreliable for the primary task to which the financial services industry applies them—building portfolios. |
 | | In 1959, Harry Markowitz, the "father of modern portfolio theory," published Portfolio Selection,² in which he proposed that investors expect to be compensated for taking additional risk, and that an infinite number of "efficient" portfolios exist along a curve defined by three variables: standard deviation, correlation coefficient, and return. |
 | | Focus, therefore, on the conclusions as to which portfolios are riskier and not on the obviously different shapes of the curves. |
