Resum 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-making t...

Typically portfolio analysis is based on the expected utility or the mean-variance approach. Although the expected utility approach is the more general one, practitioners still appreciate the mean-variance approach. We give a common framework including both types of selection criteria as special cases by considering portfolio problems with terminal wealth constraints. Moreover, we propose a sol...

This paper examines the so called 1/n investment puzzle which has been observed in defined contribution plans whereby some participants divide their contributions equally among the available asset classes. It has been argued that this is a very naive strategy since it contradicts the fundamental tenets of modern portfolio theory. We use simple arguments to show that this behavior is perhaps les...

Using high-frequency data, we decompose the time-varying beta for stocks into beta for continuous systematic risk and beta for discontinuous systematic risk. Estimated discontinuous betas for S&P500 constituents between 2003 and 2011 generally exceed the corresponding continuous betas. We demonstrate how continuous and discontinuous betas decrease with portfolio diversification. Using an equiwe...

Data warehouses are characterized in general by heterogeneous data sources providing information with different levels of quality. In such environments many data quality approaches address the importance of defining the term “data quality” by a set of dimensions and providing according metrics. The benefit is the additional quality information during the analytical processing of the data. In th...

Stocks market performance measurement has long been regarded as the most interesting part in investment. Many new methods emerge every year but most of these are rooted from Modern Portfolio theory by Harry Markowitz. In this research paper, we have used the efficient frontier from modern portfolio theory to determine the best stocks performance in KLCI index from 2006-2010. The data is compare...

Migrating a live, running operating system from one machine to another has proven to be an invaluable tool over the past few years. Today, however, the only way to migrate an OS is to run it in virtual machine, thereby incurring the disadvantages of virtualization (e.g., virtualized devices often do not keep pace with the latest hardware). This paper proposes a new infrastructure for operating ...
