In this study, we use zero-one variables to control fixed transaction costs independent of trade size in the portfolio selection problem. The optimal solution to the maximum flow, risk constrained stochastic portfolio network is found using Digital Portfolio Theory (DPT). Digital signals...

While the literature on Socially Responsible Investment (SRI) is mainly focused on the stock market, little attention has been paid to SRI in sovereign bonds. This paper investigates the effect of taking into account socially responsible indicators for countries, the Vigeo Sustainability Ratings...

Using a data-set that provides unprecedented details on individual investors’ stockholdings, we analyse whether investors take into account corporate governance when they select stocks. After controlling for the supply effect via free float and other firm characteristics, we find that all...

This paper investigates the diversification prospects which may be reaped when investing in a mixture of emerging and developed market assets. Given that emerging markets are somewhat distinct from developed ones, one may expect significant diversification potential and therefore risk reduction....

We develop a new family of estimators of the covariance matrix that relies solely on forwardlooking information. It uses only current prices of plain-vanilla options. In an out-of-sample study we show that a minimum-variance strategy based on these fully-implied estimators outperforms several...

This paper proposes a new way to measure and deal with risk within the portfolio selection problem using a skewness/semivariance biobjective optimization framework. The solutions of this biobjective optimization problem allow the investor to analyse the efficient trade-off between skewness and...
