This study consists in the construction of long-only absolute return fund-of-funds (FoF) for the Private Banking Division
of a major financial institution. The project is part of the institution’s recent initiative to enhance its portfolio construction
framework and to equip managers with sophisticated optimization models and tools to deal with the unintended movements
of financial markets. More specifically, the fund construction model presented in the paper is used by the Private
Banking division for its new ”Absolute Return” investment program which aims at extending the availability of absolute
return financial products to individual investors.
The portfolio selection discipline goes back to the Markowitz mean-variance portfolio optimization model [31]
which is based on the trade-off between risk and return and in which the diversification principle plays a dominant role.
The mean-variance portfolio selection model is a quadratic optimization problem that defines the proportion of capital
to be invested in each considered asset. Since Markowitz’s work, many other portfolio optimization models have been
proposed. The main motivations have been threefold and relate to
– the mitigation of the impact of the estimation risk [5]: many empirical studies (see, e.g., [11, 33]) have shown that the
optimal portfolio is extremely sensitive to the estimation of the inputs, and, in particular, that errors in the estimation
of the expected returns have a much larger impact than those in the estimation of the variances and covariances.
Asset managers would thus rather trade-off some return for a more secure portfolio that performs well under a wider
