in the portfolio selection problem, the manager considers several objectives simultaneously such as the rate of return, the liquidity and the risk of portfolios. these objectives are conflicting and incommensurable. moreover, the objectives can be imprecise. generally, the portfolio manager seeks the best combination of the stocks that meets his investment objectives. the imprecise goal program...

Many transportation agencies have discovered that traditional highway contract administration procedures and project delivery methods do not meet current demands. In response, they are turning to alternative contracting. Four trends are perceived in road management. First, with respect to project delivery, more and more projects are contracted for the whole life cycle of the road. Second, contr...

in the research we try to introduce “network matrix” in selecting optimizing portfolio for active management in investment companies, to evaluating obtained portfolio of this, with this aim that have high efficiency in relation to market portfolio efficiency. first matrix (portfolio) is value-growth stocks that are classified by standards p/e and p/b and second matrix (portfolio) are an aggress...

Cross-ownership smooths firms' idiosyncratic shocks but affects their portfolio choice and, therefore, risk-taking position. The classical intuition on the role of pooling risk in raising welfare is valid when ownership evenly dispersed. However, some firms concentrated hands a few others, deeper integration leads to excessive and volatility consequently, it results lower aggregate welfare.

Introduction One of the basic problems of applied finance is the optimal selection of stocks by conflicting objective of maximizing future return and minimizing investment risk. The first systematic treatment of this dilemma is the mean variance approach proposed by Markowitz. Markowitz combined the optimization and probability theory to solve the dilemma. In Markowitz’s mean variance model, th...

We explore theoretically and experimentally the general equilibrium price and allocation implications of delegated portfolio management when the investor-manager relationship is non-exclusive. Investors transfer their securities allocations to managers, managers trade in a competitive marketplace to achieve new allocations, and payo↵s are distributed back to investors after subtraction of a por...

In this paper, we show that although minimum-variance hedging unambiguously reduces the standard deviation of portfolio returns, it tends to increase portfolio kurtosis and consequently the effectiveness of hedging in terms of a more general measure of risk such as VaR is uncertain. We compare the reduction in standard deviation with the reduction in 99% VaR for thirteen cross-hedged currency p...

This chapter provides an introduction to the advent of Information Technology Outsourcing (ITO) and its impact on portfolio management in modern day decision-making. Specifically, it outlines the use of the Application Portfolio Matrix (APM) by companies in formulating their strategic IT direction and why such techniques may be unsuitable for outsourcing decisions, which are inherently complex ...

This paper studies the role of detrended wealth in predicting stock returns. We call a transitory movement in wealth one that produces a deviation from its shared trend with consumption and labor income. Using U.S. quarterly stock market data we find that these trend deviations in wealth are strong predictors of both real stock returns and excess returns over a Treasury bill rate. We also find ...
