There is a variety of models for portfolio selection. However, in portfolio theory applications little or no attention is paid to the cardinality problem. In this paper, an algorithm for dealing with this problem is presented. The proposed allocation algorithm is implemented in a software system, which is based on the Fuzzy Logic Q-measure Model and manages financial investments in real time. T...

In den vergangenen Jahren entwickelte sich Magnetresonanztomographie (MRT)-geführte Brust-Biopsie zu einer der vielversprechendsten Verfahren innerhalb des Feldes der interventionellen Magnetresonanztomographie (iMRI). Die vorliegende Arbeit präsentiert ein neu entwickeltes Verfahren zur verbesserten Echtzeitnadelführung unter Nutzung eines optischen Moiré Phase Tracking (MPT) Systems. Es ermög...

In the perspective of oil-importers, this paper considers an extension of the Value at Risk approach incorporated with timevarying conditional volatility model to trace the actual dynamic risk of regional oil-importing portfolio caused by the country risk volatility. With an application to oil economies in the Former Soviet Union (FSU) region, empirical results show that the country portfolio r...

Abstract The optimum portfolio selection for an investor with particular preferences was proven to lie on the normalized efficient frontier between two bounds defined by the Ballestero (1998) bounding theorem. A deeper understanding is possible if the decision-maker is provided with visual and quantitative techniques. Here, we derive useful insights as a way to support investor?s decision-makin...

We develop a numerical scheme for determining the optimal asset allocation strategy for time-consistent, continuous time, mean variance optimization. Any type of constraint can be applied to the investment policy. The optimal policies for time-consistent and pre-commitment strategies are compared. When realistic constraints are applied, the efficient frontiers for the precommitment and time-con...

This study examines the relationships between stock fundamental ratios and idiosyncratic volatility from 1993 to 2010 for Australian Securities Exchange listed companies. The portfolio analysis results show that high idiosyncratic volatility companies tend to be small (measured by size), highly leveraged (measured by interest cover ratio), low profitability (measured by return on equity and ear...

Optimality conditions are derived for problems of minimizing a general measure of deviation of a random variable, with special attention to situations where the random variable could be the rate of return from a portfolio of financial instruments. General measures of deviation go beyond standard deviation in satisfying axioms that do not demand symmetry between ups and downs. The optimality con...

THE CURRENT PAPER BY YACINE AIT-SAHALIA and Michael W. Brandt ~henceforth AB! addresses two issues that are of central concern in portfolio choice: How can portfolio advice be made realistic while remaining tractable? How can

Studies of bank diversification, as well as Basel II regulatory framework, use indirect methods of characterizing the sources of diversification in bank portfolios. The present paper more directly estimates the sources of diversification in thirteen retail credit categories from asset-backed security performance measures that are highly correlated with (unobservable) loan value. Classical Marko...
